+<h2>Introduction</h2>
+
+tmake is an easy-to-use tool for creating and maintaining makefiles across
+many platforms and compilers. The idea is that you should spend your time
+writing code, not makefiles.
+
+<p>
+We wrote tmake because we spent too much time maintaining makefiles for
+Windows and Unix compilers. Being the developer of the multi-platform GUI
+toolkit <a href="http://www.troll.no/qt">Qt</a>, Troll Tech must provide
+Qt makefiles for more than 30 different OS/compiler combinations.
+
+<p>
+We looked at GNU autoconf, but it was Unix-specific and not flexible
+enough in our opinion. Our makefile system also had to deal with Qt
+<a href="http://www.troll.no/qt/metaobjects.html">meta object
+compiler</a> (moc) issues. The moc program extracts meta information from
+C++ files and generates a C++ file with data tables etc. It takes work to
+add makefile rules for the moc and wanted to automate this task.
+
+<p>
+The tmake project was started around mid 1996 and version 1.0 was released
+in September 1997. It soon became a success and is now widely used among
+Qt programmers.
+
+<p>
+tmake is written in Perl and requires perl version 5 or newer. You do not
+need to be familiar with Perl programming to use tmake, but you should
+learn Perl if you want to write your own makefile templates.
+
+<p>
+<b>Windows users:</b> The tmake distribution for Win32 includes tmake.exe
+(built by the perl2exe utility) and you do not need to download and
+install perl unless you want to modify the tmake source code or run other
+perl scripts. You can download perl for Win32 (Windows NT and 95) from <a
+href="http://www.activestate.com">www.activestate.com</a>
+
+<p>
+Feedback is highly appreciated. Contact the author hanord@troll.no if you
+have ideas, patches etc. for tmake.
+
+
+<hr>
+<h2>Installation</h2>
+
+<ol>
+<li>Make sure you have perl version 5 or later installed (optional
+for Windows users).
+<li>Unpack the tmake tar.gz or zip archive.
+<li>Set the TMAKEPATH environment variable to the directories
+containing the template files (see below).
+<li>Add the tmake/bin directory to your PATH.
+</ol>
+
+Here are some examples:<p>
+<strong>Unix Bourne shell:</strong><pre>
+ TMAKEPATH=/local/tmake/lib/linux-g++
+ PATH=$PATH:/local/tmake/bin
+ export TMAKEPATH PATH
+</pre>
+
+<strong>Unix C shell:</strong><pre>
+ setenv TMAKEPATH /local/tmake/lib/linux-g++
+ setenv PATH $PATH:/local/tmake/bin
+</pre>
+
+<strong>Windows NT and Windows 95:</strong><pre>
+ set TMAKEPATH=c:\tmake\lib\win32-msvc
+ set PATH=%PATH%;c:\tmake\bin
+</pre>
+
+<p>
+The template directory name has the form <em>platform</em>-<em>compiler</em>.
+Each template directory contains template files and a configuration file.
+
+<p>
+Supported platforms: AIX, Data General, FreeBSD, HPUX, SGI Irix, Linux,
+NetBSD, OpenBSD, OSF1/DEC, SCO, Solaris, SunOS, Ultrix, Unixware and
+Win32.
+
+<p>
+Have a look at the tmake/lib directory to see if your platform-compiler
+combination is supported. If it's not there, please tell us.
+
+<p>
+<b>Unix users:</b> tmake requires that perl is in /usr/bin. If your
+version of perl is elsewehere, either change the first line of tmake or
+make a small shell script which invokes tmake with the correct perl.
+
+
+<hr>
+<h2>Getting Started</h2>
+
+Let's assume you have a small Qt application consisting of one C++ header
+file and two source files.
+
+First you need to create a project file, e.g. hello.pro:<pre>
+ HEADERS = hello.h
+ SOURCES = hello.cpp main.cpp
+ TARGET = hello
+</pre>
+
+Then run tmake to create a Makefile:<pre>
+ tmake hello.pro -o Makefile
+</pre>
+And finally:<pre>
+ make
+</pre>
+This builds the hello program. Remember to set the <code>TMAKEPATH</code>
+environment variable before you run tmake.
+<p>
+See <a href="m-linux-gcc.html">Makefile for Linux/g++</a>.<br>
+See <a href="m-win32-msvc.html">Makefile for Win32/msvc</a>
+(Microsoft Visual C++).<br>
+
+
+<hr>
+<h2>Makefile Templates</h2>
+
+The tmake distribution includes three makefile templates and one
+configuration file for each platform/compiler combination. The
+<code>TMAKEPATH</code> environment variable tells tmake where to find
+these files:
+<p>
+<table border="0">
+ <tr>
+ <td>&nbsp;</td>
+ <td>app.t</td>
+ <td>&nbsp;</td>
+ <td>Creates a makefile for building applications.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>lib.t</td>
+ <td>&nbsp;</td>
+ <td>Creates a makefile for building libraries.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>subdirs.t</td>
+ <td>&nbsp;</td>
+ <td>Creates a makefile for building targets in subdirectories.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>tmake.conf</td>
+ <td>&nbsp;</td>
+ <td>This configuration file contains compiler options and lists
+ tools and libraries.
+ </tr>
+</table>
+
+
+<p>
+The hello.pro project file above does not have a <code>TEMPLATE</code> or
+a <code>CONFIG</code> tag. The default template is <tt>app</tt> (the .t
+extension is optional) and the default configuration is <tt>qt warn_on
+release</tt>.
+
+This project file produces exactly the same result as the hello.pro
+above:<pre>
+ TEMPLATE = app
+ CONFIG = qt warn_on release
+ HEADERS = hello.h
+ SOURCES = hello.cpp main.cpp
+ TARGET = hello
+</pre>
+
+
+
+<h4>Makefile Configuration</h4>
+
+<p>
+The <code>CONFIG</code> tag is recognized by both the app.t and lib.t
+templates and specifies what compiler options to use and which extra
+libraries to link in.
+
+These options control the compilation flags:
+<p>
+<table border="0">
+ <tr>
+ <td>&nbsp;</td>
+ <td>release</td>
+ <td>&nbsp;</td>
+ <td>Compile with optimization enabled, ignored if
+ "debug" is specified.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>debug</td>
+ <td>&nbsp;</td>
+ <td>Compile with debug options enabled.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>warn_on</td>
+ <td>&nbsp;</td>
+ <td>The compiler should emit more warnings than normally, ignored if
+ "warn_off" is specified.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>warn_off</td>
+ <td>&nbsp;</td>
+ <td>The compiler should emit no warnings or as few as possible.</td>
+ </tr>
+</table>
+
+<p>
+These options defines the application/library type:
+<p>
+<table border="0">
+ <tr>
+ <td>&nbsp;</td>
+ <td>qt</td>
+ <td>&nbsp;</td>
+ <td>The target is a Qt application/library and requires Qt header
+ files/library.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>opengl</td>
+ <td>&nbsp;</td>
+ <td>The target requires the OpenGL (or Mesa) headers/libraries.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>x11</td>
+ <td>&nbsp;</td>
+ <td>The target is a X11 application (app.t only).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>windows</td>
+ <td>&nbsp;</td>
+ <td>The target is a Win32 window application (app.t only).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>console</td>
+ <td>&nbsp;</td>
+ <td>The target is a Win32 console application (app.t only).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>dll</td>
+ <td>&nbsp;</td>
+ <td>The target is a shared object/DLL (app.t only).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>staticlib</td>
+ <td>&nbsp;</td>
+ <td>The target is a static library (lib.t only).</td>
+ </tr>
+</table>
+
+<p>
+As an example, if the hello application uses both Qt and OpenGL and you
+want to compile it for debugging, your <code>CONFIG</code> line should
+read:<pre>
+ CONFIG = qt opengl debug
+</pre>
+
+<p>
+The most common tmake options and project tags are described here.
+See the tmake <a href="tmake_ref.html">reference manual</a> for
+details.<p>
+
+
+
+<h4>The Application Template</h4>
+
+The application template, app.t, lets you compile and link executable
+programs or shared objects (DLLs).
+
+This template recognizes several tags.
+<p>
+<table border="0">
+ <tr>
+ <td>&nbsp;</td>
+ <td>HEADERS</td>
+ <td>&nbsp;</td>
+ <td>Header files.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>SOURCES</td>
+ <td>&nbsp;</td>
+ <td>Source files.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>TARGET</td>
+ <td>&nbsp;</td>
+ <td>Name of executable (adds .exe if on Windows).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>DESTDIR</td>
+ <td>&nbsp;</td>
+ <td>Where to put the target.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>DEFINES</td>
+ <td>&nbsp;</td>
+ <td>Tell compiler to define C preprocessor macros (-D option).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>INCLUDEPATH</td>
+ <td>&nbsp;</td>
+ <td>Sets the include file search path for the compiler (-I
+ option).
+ </td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>DEPENDPATH</td>
+ <td>&nbsp;</td>
+ <td>Sets the dependency search path for tmake.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>DEF_FILE</td>
+ <td>&nbsp;</td>
+ <td>Win32 only: Link with a .def file.</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>RC_FILE</td>
+ <td>&nbsp;</td>
+ <td>Win32 only: Use a .rc file (compile to temporary .res).
+ </td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>RES_FILE</td>
+ <td>&nbsp;</td>
+ <td>Win32 only: Link with a .res file.
+ </td>
+ </tr>
+</table>
+
+<p>
+
+
+<h4>The Library Template</h4>
+
+The library template, lib.t, lets you compile and create static or shared
+libraries.
+
+<p>
+The lib.t template supports the same project tags as app.t, but also
+<code>VERSION</code>. <code>VERSION</code> is the version number of the
+target library, e.g. 1.40. The version is important for Unix shared
+libraries, but ignored on Windows.
+
+
+
+<h4>The Subdirs Template</h4>
+
+The subdirs template, subdirs.t, lets you invoke make in subdirectories.
+
+<p>The <code>SUBDIRS</code> tag contains the name of all subdirectories to
+be processed.
+
+
+<h4>Special Templates for Microsoft Visual C++</h4>
+
+If you have Microsoft Visual C++ 5.0, you can use two special templates to
+generate a MSVC++ IDE project (.dsp file). After you have generated
+e.g. hello.dsp, choose "File"->"Open Workspace" and select the hello.dsp
+file. Visual C++ will then create a workspace (.dsw file) for you.<p>
+<table border="0">
+ <tr>
+ <td>&nbsp;</td>
+ <td>vcapp.t</td>
+ <td>&nbsp;</td>
+ <td>Creates an application project file (Microsoft Visual C++ 5.0
+ only).</td>
+ </tr>
+ <tr>
+ <td>&nbsp;</td>
+ <td>vclib.t</td>
+ <td>&nbsp;</td>
+ <td>Creates a library project file (Microsoft Visual C++ 5.0
+ only).</td>
+ </tr>
+</table>
+
+<p>
+Run tmake to create a hello.dsp file (use -t to override the default
+template):<pre>
+ tmake -t vcapp -o hello.dsp hello.pro
+</pre>
+
+
+<hr>
+<h2><a name="usage"></a>Program Usage: tmake</h2>
+
+Usage:<pre>
+ tmake [options] <em>project-file</em>
+</pre>
+Options:<pre>
+ -e expr Evaluate the Perl expression. Ignores the template file.
+ -nodepend Don't generate dependency information.
+ -o <em>file</em> Write output to <em>file</em> instead of stdout.
+ -p <em>file</em> Load an additional project file.
+ -t <em>file</em> Specify a template <em>file</em>.
+ -unix Force tmake into Unix mode.
+ -v Verbose/debugging on.
+ -win32 Force tmake into Win32 mode.
+</pre>
+
+The -t option overrides any <code>TEMPLATE</code> tag in the project file.
+<p>
+The default project file extension is ".pro". The default template file
+extension is ".t". If you do not specify these extension tmake will
+automatically add them for you.
+<p>
+
+
+<hr>
+<h2><a name="progen"></a>The progen Utility</h2>
+
+The progen utility creates project files for you. It can be used like
+this:<pre>
+ progen -n hello -o hello.pro
+</pre>
+If no .cpp or .h files are specified on the command line, progen
+searches for .cpp and .h (except moc_*.cpp) in the current directory
+and below.
+<p>
+Usage:<pre>
+ progen [options] [<em>C/C++ header files and source files</em>]
+</pre>
+Options:<pre>
+ -lower Lower-case letters in filenames (useful on Windows).
+ -n <em>name</em> Specify a project name (<code>TARGET</code>).
+ -o <em>file</em> Write output to <em>file</em> instead of stdout.
+ -t <em>file</em> Specify a template <em>file</em>.
+</pre>
+
+
+<hr>
+<h2>Advanced Topics</h2>
+
+In most cases you will be happy with using tmake as described above, but
+sometimes you need to add special compiler options or even add new
+makefile rules. This chapter describes how to customize your makefiles.
+
+<h4>Conditional Project Settings</h4>
+
+If you need a special compiler option etc., you can add platform-dependent
+settings in your project file:<pre>
+ solaris-cc:TMAKE_CC = /opt/bin/CC_5.0
+ solaris-cc:TMAKE_CFLAGS = -pts
+ unix:TMAKE_LIBS = -lXext
+ win32:INCLUDE_PATH = c:\myinclude
+ win32-borland:DEFINES = NO_BOOL
+</pre>
+
+You can prefix a project tag with unix: or win32: to make it specific for
+either Unix or Windows. You can also prefix tags with
+<em>platform-compiler</em>
+
+<h4>Your Own Templates</h4>
+
+If you know Perl programming, there is virtually no limitation to what you
+can do with tmake. First you need to know how tmake works.
+
+<h4>Template Processing</h4>
+
+When you run tmake, it first reads the <tt>tmake.conf</tt> file.
+This configuration file has the same syntax as the project file.
+
+tmake then reads the project file and sets the project tags it
+finds, e.g. <code>HEADERS</code>, <code>SOURCES</code> etc.
+
+All tags and values are stored in a global associative Perl hash
+array called <code>project</code>. For example,
+<code>$project{"SOURCES"}</code> contains "hello.cpp main.cpp"
+after processing hello.pro.
+
+When both the <tt>tmake.conf</tt> and the project files have been
+read, tmake starts reading the template file line by line and
+executes any Perl code it finds in the template.
+
+<ul>
+<li>Anything after <code>#$</code> until newline is
+ evaluated as perl code. The perl code is substituted
+ with the contents of the <code>$text</code>
+ variable.
+<li>Block of perl code: <code>#${</code> until
+ <code>#$}</code>.
+<li>Comments; <code>#!</code> until newline is stripped.
+<li>Anything else is copied directly from the template to
+ the output.
+</ul>
+
+<p>
+Example:<pre>
+ #! This is a comment which will be removed.
+ This text will appear in the output.
+ #$ $text = "The header file(s) are: " . $project{"HEADERS"};
+ # This text also appears in the output.
+ #${
+ $a = 12;
+ $b = 13;
+ $text = $a * $b;
+ #$}
+ That's all.
+</pre>
+Output:<pre>
+ This text will appear in the output.
+ The header file(s) are: hello.h
+ # This text also appears in the output.
+ 156
+ That's all.
+</pre>
+
+
+<h3>Using tmake With Lex and Yacc</h3>
+
+The standard tmake templates knows how to process C and C++ files, but
+sometimes you need to process additional files and link them into your
+project. A typical example is to process lex and yacc files when you're
+building a parser.
+
+<p>
+Parser template:<pre>
+ #!
+ #! parser.t: This is a custom template for building a parser
+ #!
+ #$ IncludeTemplate("app.t");
+
+ ####### Lex/yacc programs and options
+
+ LEX = flex
+ YACC = #$ $text = ($is_unix ? "yacc -d" : "byacc -d");
+
+ ####### Lex/yacc files
+
+ LEXIN = #$ Expand("LEXINPUT");
+ LEXOUT = lex.yy.c
+ YACCIN = #$ Expand("YACCINPUT");
+ YACCOUT = y.tab.c
+ YACCHDR = y.tab.h
+ PARSER = #$ Expand("PARSER");
+
+ ####### Process lex/yacc files
+
+ $(LEXOUT): $(LEXIN)
+ $(LEX) $(LEXIN)
+
+ $(PARSER): $(YACCIN) $(LEXOUT)
+ $(YACC) $(YACCIN)
+ #$ $text = ($is_unix ? "-rm -f " : "-del ") . '$(PARSER)';
+ #$ $text = ($is_unix ? "-mv " : "-ren ") . '$(YACCOUT) $(PARSER)';
+</pre>
+
+The parser template adds some extra rules to the application template
+in order to build the lex and yacc portions of the project. This
+template is portable across Unix and Windows since it generates different
+commands depending on the <code>$is_unix</code> variable.
+
+<p>
+To learn more about the Expand() function and other Perl functions which
+tmake provides, consult the <a href="tmake_ref.html">reference manual</a>.
+
+<p>
+Example project file:<pre>
+ TEMPLATE = parser.t
+ CONFIG = console release
+ LEXINPUT = lexer.l
+ YACCINPUT = grammar.y
+ PARSER = parser.cpp
+ SOURCES = $$PARSER \
+ node.cpp \
+ asmgen.cpp
+ TARGET = parser
+</pre>
+
+Here we use macro expansion <code>$$PARSER</code> to avoid writing parser.cpp
+two places.
+
+
+<h3>Counting the Number of Code Lines</h3>
+
+tmake is generic since it is based on Perl. You can create your own
+templates for other purposes than producing makefiles. Here is an example
+template that counts the number of code lines in our project.
+
+<p>
+Template wc.t:<pre>
+ #! Template that count number of C++ lines.
+ The number of C++ code lines for #$ $text=$project_name;
+ #${
+ $files = $project{"HEADERS"} . " " . $project{"SOURCES"};
+ $text = `wc -l $files`;
+ #$}
+</pre>
+Run it:<pre>
+ tmake -t wc hello
+</pre>
+Output:<pre>
+ The number of C++ code lines for hello.pro
+ 25 hello.h
+ 98 hello.cpp
+ 38 main.cpp
+ 161 total
+</pre>
+This will only work if the wc program is installed on your system.
