-This file contains a collection of notes that various people have
-provided about porting Tcl to various machines and operating systems.
-I don't have personal access to any of these machines, so I make
-no guarantees that the notes are correct, complete, or up-to-date.
-If you see the word "I" in any explanations, it refers to the person
-who contributed the information, not to me;  this means that I
-probably can't answer any questions about any of this stuff.  In
-some cases, a person has volunteered to act as a contact point for
-questions about porting Tcl to a particular machine;  in these
-cases the person's name and e-mail address are listed.  I'm
-interested in getting new porting information to add to the file;
-please mail updates to "john.ousterhout@eng.sun.com".

-This file reflects information provided for Tcl 7.4 and later releases (8.x).
-If there is no information for your configuration in this file, check
-the file "porting.old" too;  it contains information that was
-submitted for Tcl 7.3 and earlier releases, and some of that information
-may still be valid.
+This file used to contain a collection of notes that various people
+had provided about porting Tcl to various machines and operating
+systems.  This information is now available in the Tcl porting
+database at the following location:
 
-A new porting database has recently become available on the Web at
-the following URL:
-    http://www.sunlabs.com/cgi-bin/tcl/info.8.0
-This page provides information about the platforms on which Tcl and
-and Tk 8.0 have been compiled and what changes were needed to get Tcl
-and Tk to compile.  You can also add new entries to that database
-when you install Tcl and Tk on a new platform.  The Web database is
-likely to be more up-to-date than this file.

---------------------------------------------
-Solaris, various versions
---------------------------------------------
-
-1. If typing "make test" results in an error message saying that
-there are no "*.test" files, or you get lots of globbing errors,
-it's probably because your system doesn't have cc installed and
-you used gcc.  In order for this to work, you have to set your
-CC environment variable to gcc and your CPP environment variable
-to "gcc -E" before running the configure script.
-
-2. Make sure that /usr/ucb is not in your PATH or LD_LIBRARY_PATH
-environment variables;  this will cause confusion between the new
-Solaris libraries and older UCB versions (Tcl will expect one version
-and get another).
-
-3. There have been several reports of problems with the "glob" command.
-So far these reports have all been for older versions of Tcl, but
-if you run into problems, edit the Makefile after "configure" is
-run and add "-DNO_DIRENT_H=1" to the definitions of DEFS.  Do this
-before compiling.
-
---------------------------------------------
-SunOS 4 and potentially other OSes
---------------------------------------------
-
-On systems where both getcwd(3) and getwd(3) exist, check the man
-page and if getcwd, like on SunOS 4, uses popen to pwd(1)
-add -DUSEGETWD to the flags CFLAGS so getwd will be used instead.
-
-That is, change the CFLAGS = -O line so it reads 
-CFLAGS = -O -DUSEGETWD
-
---------------------------------------------
-Linux, ELF, various versions/distributions
---------------------------------------------
-
-If ./configure --enable-shared complains it can not do a shared
-library you might have to make the following symbolic link:
-ln -s /lib/libdl.so.1 /lib/libdl.so
-then remove config.cache and re run configure.
-
---------------------------------------------
-Pyramid DC/OSx SVr4, DC/OSx version 94c079
---------------------------------------------
-
-Tcl seems to dump core in cmdinfo.test when compiled with the
-optimiser turned on in TclEval which calls 'free'.  To get around
-this, turn the optimiser off.
-
---------------------------------------------
-SGI machines, IRIX 5.2, 5.3, IRIX64 6.0.1
---------------------------------------------
-
-1. If you compile with gcc-2.6.3 under some versions of IRIX (e.g.
-   4.0.5), DBL_MAX is defined too large for gcc and Tcl complains
-   about all floating-point values being too large to represent.
-   If this happens, redefining DBL_MAX to 9.99e299.
-
-2. Add "-D_BSD_TIME" to CFLAGS in Makefile.  This avoids type conflicts
-in the prototype for the gettimeofday procedure.
-
-2. If you're running under Irix 6.x and tclsh dumps core, try
-removing -O from the CFLAGS in Makefile and recompiling;  compiler
-optimizations seem to cause problems on some machines.
-
---------------------------------------------
-IBM RTs, AOS
---------------------------------------------
-
-1. Steal fmod from 4.4BSD
-2. Add a #define to tclExpr such that:
-extern double fmod(); 
-is defined conditionally on ibm032
-
---------------------------------------------
-QNX 4.22
---------------------------------------------
-
-tclPort.h
-	- commented out 2 lines containing #include <sys/param.h>
-
-tcl.h
-	- changed  #define VARARGS ()
-	- to       #ifndef __QNX__
-	             #define VARARGS ()
-	           #else
-	             #define VARARGS (void *, ...)
-	           #endif
-
---------------------------------------------
-Interactive UNIX
---------------------------------------------
-
-Add the switch -Xp to LIBS in Makefile;  otherwise strftime will not
-be found when linking.
-
---------------------------------------------
-Motorola SVR4 V4.2 (m88k)
---------------------------------------------
-
-For Motorola Unix R40V4.2 (m88k architechure), use /usr/ucb/cc instead of
-/usr/bin/cc.  Otherwise, the compile will fail because of conflicts over
-the gettimeofday() call.
-
-Also, -DNO_DIRENT_H=1 is required for the "glob" command to work.
-
---------------------------------------------
-NeXTSTEP 3.x
---------------------------------------------
-
-Here's the set of changes I made to make 7.5b3 compile cleanly on
-NeXTSTEP3.x.
-
-Here are a couple lines from unix/Makefile:
-
-# Added utsname.o, which implements a uname() emulation for NeXTSTEP.
-COMPAT_OBJS =		 getcwd.o strtod.o tmpnam.o utsname.o
-
-TCL_NAMES=\
-	-Dstrtod=tcl_strtod -Dtmpnam=tcl_tmpnam -Dgetcwd=tcl_getcwd \
-	-Dpanic=tcl_panic -Dmatherr=tcl_matherr \
-	-Duname=tcl_uname -Dutsname=tcl_utsname
-
-# Added mode_t, pid_t, and O_NONBLOCK definitions.
-AC_FLAGS =		 -DNO_DIRENT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_SYS_TIME_H=1  
--DTIME_WITH_SYS_TIME=1 -DHAVE_TM_ZONE=1 -DHAVE_TM_GMTOFF=1 -DHAVE_TIMEZONE_VAR=1  
--DSTDC_HEADERS=1 -Dmode_t=int -Dpid_t=int -DO_NONBLOCK=O_NDELAY ${TCL_NAMES}
-
-
-Here are diffs for other files.  utsname.[hc] are a couple files I added
-to compat/  I'm not clear whether that's where they legitimately belong
-- I considered stashing them in tclLoadNext.c instead.  The tclIO.c
-change was a bug, I believe, which I reported on comp.lang.tcl and
-has apparently been noted and fixed.  The objc_loadModules() change
-allows "load" to load object code containing Objective-C code in
-addition to plain C code.

- 
-The macro va_start in /usr/include/stdarg.h is incorrectly terminated by
-a semi-colon.  This causes compile of generic/tclBasic.c to fail.  The
-best solution is to edit the definition of va_start to remove the `;'.
-This will fix this file for anything you want to compile.  If you don't have
-permission to edit /usr/include/stdarg.h in place, copy it to the tcl unix
-directory and change it there.

-Linux 1.2.13 (gcc 2.7.0, libc.so.5.0.9)
---------------------------------------------
-
-Symptoms:
-
-*	Some extensions could not be loaded dynamically, most
-	prominently Blt 2.0
-
-	The given error message essentially said:
-	Could not resolve symbol '__eprintf'.
-
-	(This procedure is used by the macro 'assert')
-
-Cause
-
-*	'__eprintf' is defined in 'libgcc.a', not 'libc.so.x.y'.
-	It is therefore impossible to load it dynamically.
-
-*	Neither tcl nor tk make use of 'assert', thereby
-	preventing a static linkage.
-
-Workaround
-
-*	I included <assert.h> in 'tclAppInit.c' / 'tkAppInit.c'
-	and then executed 'assert (argc)' just before the call
-	to Tcl_Main / Tk_Main.
-
-	This forced the static linkage of '__eprintf' and
-	everything went fine from then on.
-
-	(Something like 'assert (1)', 'assert (a==a)' is not
-	sufficient, it will be optimized away).
