Tutorial

Step 1: Download and Unpack

First, you should ensure that your system meets mingw-cross-env's requirements. You will almost certainly have to install some stuff.

When everything is fine, download the latest release:

wget https://bitbucket.org/vog/mingw-cross-env/downloads/mingw-cross-env-X.Y.tar.gz

and unpack the tarball:

tar -xzvf mingw-cross-env-X.Y.tar.gz

If you don't mind installing it in your home directory, just skip the following step and go straight to step 3.

Step 2: System-wide Installation (optional)

Now you should save any previous installation of the mingw-cross-env. Assuming you've installed it under /opt/mingw (any other directory will do as well), you should execute the following commands:

su
mv /opt/mingw /opt/mingw.old
exit

Then you need to transfer the entire directory to its definitive location. We will assume again you use /opt/mingw, but feel free to use any other directory if you like.

su
mv mingw-cross-env-X.Y /opt/mingw
exit

We're almost done. Just change to your newly created directory and get going:

cd /opt/mingw

Step 3: Build mingw-cross-env

Enter the directory where you've unpacked the mingw-cross-env. Now it depends on what you actually want – or need.

If you choose to enter:

make

you're in for a long wait, because it compiles a lot of packages. On the other hand it doesn't require any intervention, so you're free to do whatever you like – like watch a movie or go for a night on the town. When it's done you'll find that you've installed a very capable Win32 cross compiler onto your system.

If you only need the most basic tools you can also use:

make gcc

and add any additional packages you need later on. You can also supply a host of packages on the command line, e.g.:

make gtk lua libidn

You'll always end up with a consistent cross compiling environment.

After you're done it just needs a little post-installation.

Step 4: Environment Variables

Edit your .bashrc script in order to change $PATH:

export PATH=/where mingw-cross-env is installed/usr/bin:$PATH

In case you are using custom $PKG_CONFIG_PATH entries, you can add separate entries for MinGW cross builds:

export PKG_CONFIG_PATH="entries for native builds"
export PKG_CONFIG_PATH_i686_pc_mingw32="entries for mingw-cross-env builds"

Remember to use i686-pc-mingw32-pkg-config instead of pkg-config for cross builds. The Autotools do that automatically for you.

Note that any other compiler related environment variables (like $CC, $LDFLAGS, etc.) may spoil your compiling pleasure, so be sure to delete or disable those.

Congratulations! You're ready to cross compile anything you like.

Step 5a: Cross compile your Project (Autotools)

If you use the Autotools, all you have to do is:

./configure --host=i686-pc-mingw32
make

Don't worry about a warning like this:

configure: WARNING: If you wanted to set the --build type, don't use --host.
If a cross compiler is detected then cross compile mode will be used.

Everything will be just fine.

Step 5b: Cross compile your Project (CMake)

If you have a CMake project, you can use the provided toolchain file:

cmake ... -DCMAKE_TOOLCHAIN_FILE=/where mingw-cross-env is installed/usr/i686-pc-mingw32/share/cmake/mingw-cross-env-conf.cmake

Step 5c: Cross compile your Project (Qt)

If you have a Qt application, all you have to do is:

i686-pc-mingw32-qmake
make

If you are using Qt plugins such as the svg or ico image handlers, you should also have a look at the Qt documentation about static plugins.

Note the sql drivers (-qt-sql-*) and the image handlers for jpeg, tiff, gif and mng are built-in, not plugins.

Step 5d: Cross compile your Project (Makefile)

If you have a handwritten Makefile, you probably will have to make a few adjustments to it:

CC=$(CROSS)gcc
LD=$(CROSS)ld
AR=$(CROSS)ar
PKG_CONFIG=$(CROSS)pkg-config

You may have to add a few others, depending on your project.

Then, all you have to do is:

make CROSS=i686-pc-mingw32-

That's it!

Step 5e: Cross compile your Project (OSG)

Using static OpenSceneGraph libraries requires a few changes to your source. The graphics subsystem and all plugins required by your application must be referenced explicitly. Use a code block like the following:

#ifdef OSG_LIBRARY_STATIC
USE_GRAPHICSWINDOW()
USE_OSGPLUGIN(<plugin1>)
USE_OSGPLUGIN(<plugin2>)
...
#endif

Look at examples/osgstaticviewer/osgstaticviewer.cpp in the OpenSceneGraph source distribution for an example. This example can be compiled with the following command:

i686-pc-mingw32-g++ \
    -o osgstaticviewer.exe examples/osgstaticviewer/osgstaticviewer.cpp \
    `i686-pc-mingw32-pkg-config --cflags openscenegraph-osgViewer openscenegraph-osgPlugins` \
    `i686-pc-mingw32-pkg-config --libs openscenegraph-osgViewer openscenegraph-osgPlugins`

The i686-pc-mingw32-pkg-config command from mingw-cross-env will automatically add -DOSG_LIBRARY_STATIC to your compiler flags.

Open Issues with NSIS

The NSIS package contains some native tools that are currently 32-bit only. In order to build these on a 64-bit system, multi-lib support must be enabled in the compiler toolchain. However, not all operating systems support this.

Since no other packages depend on it, the remainder of mingw-cross-env can be successfully built by simply removing the package:

rm where mingw-cross-env is unpacked/src/nsis.mk

Usage

All build commands also download the packages if necessary.

In a BSD userland, substitute "make" with "gmake".

make
build all packages, non-parallel
make gcc
build a minimal useful set of packages, i.e. the cross compilers and the most basic packages, non-parallel
make foo bar
build packages "foo", "bar" and their dependencies, non-parallel
make foo bar -j 4 JOBS=2
build packages "foo", "bar" and their dependencies, where up to 4 packages are build in parallel, each with up to 2 compiler processes running in parallel
make check-requirements
check most of the requirements if necessary – executed automatically before building packages
make download
download all packages, non-parallel, such that subsequent builds work without internet access
make download-foo download-bar
download packages "foo", "bar" and their dependencies, non-parallel
make download-foo download-bar -j 4
download packages "foo", "bar" and their dependencies, where up to 4 packages are downloaded in parallel
make strip
strip all package builds and remove unnecessary files
make clean
remove all package builds – use with caution!
make clean-pkg
remove all unused package files, handy after a successful update
make update
for internal use only! – update the version numbers of all packages, download the new versions and note their checksums
make dist
build a source distribution tarball and the website

List of Packages

See something missing? Feel free to create a new package.

Guidelines for Creating Packages

  1. The package should be a free software library that is really used by one of your applications.

    BTW, we're always curious about the applications people are porting. We maintain a list of projects which use mingw-cross-env. No matter whether your project is free or proprietary – as long as it has its own website, we'd be happy to link to it.

    Also, feel free to link to us. :-)

  2. Grep through the src/*.mk files to find a project that is most similar to yours. (Really, grep is your friend here.)

    For instance, when adding a GNU library, you should take a package like gettext.mk or libiconv.mk as the base of your work. When using a SourceForge project, you could start with a copy of xmlwrapp.mk. And so on.

  3. Adjust the comments, fill in the $(PKG)_* fields.

    Be especially careful with the $(PKG)_DEPS section. The easiest way to get the dependencies right is to start with a minimal setup. That is, initialize mingw-cross-env with make gcc only, then check whether your package builds successfully.

    Always list the dependency on gcc explicitly:

    $(PKG)_DEPS     := gcc ...
  4. Write your $(PKG)_BUILD. If your library has a ./configure script, enable/disable all dependency libraries explicitly via "--enable-*" and "--disable-*" options.

  5. You might also have to provide a patch for it. In that case, have a look at other patches such as sdl-2-fix-dinput.patch. In particular, each patch file should be named as:

    PACKAGE-PATCHNUMBER-DESCRIPTION.patch

    and should start with:

    This file is part of mingw-cross-env.
    See doc/index.html for further information.
    
    This patch has been taken from:
    https://...

    where the URL points to the bugtracker entry, mailing list entry or website you took the patch from.

    If you created the patch yourself, please offer it to the upstream project first, and point to that URL, using the same wording: "This patch has been taken from:".

    Depending on the feedback you get from the upstream project, you might want to improve your patch.

  6. If you find some time, please provide a minimal test program for it. It should be simple, stand alone and should work unmodified for many (all?) future versions of the library. Test programs are named as:

    PACKAGE-test.c
    or
    PACKAGE-test.cpp

    depending on whether it is a C or C++ library. To get a clue, please have a look at existing test programs such as sdl-test.c.

    At the very end of your *.mk file you should build the test program in a generic way, using strict compiler flags. The last few lines of sdl.mk will give you a clue.

  7. You could also try to provide a $(PKG)_UPDATE section. However, that requires some experience and "feeling" for it. So it is perfectly okay if you leave the $(PKG)_UPDATE section empty. We'll fill that in for you. It's a funny exercise.

  8. Check that you don't have "dirty stuff" in your *.mk files, such as TAB characters or trailing spaces at lines endings. Have a look at random *.mk files to get a feeling for the coding style.

    The same holds for your test program.

    However, patch files should always appear in the same coding style as the files they are patching.

    Finally, in your $(PKG)_BUILD section, please check that you use our portability variables:

    bash $(SHELL)
    install $(INSTALL)
    libtool $(LIBTOOL)
    libtoolize$(LIBTOOLIZE)
    make $(MAKE)
    patch $(PATCH)
    sed $(SED)
  9. Check whether everything runs fine. If you have some trouble, don't hesitate to ask on the mailing list, providing your *.mk file so far.

  10. Propose your final *.mk file to the mailing list. Don't forget to tell us if there are some pieces in your *.mk file you feel unsure about. We'll then have a specific look at those parts, which avoids trouble for you and us in the future.
