Cross compiling 4tH:
and running it:
MXE (M cross environment) is a Makefile that compiles a cross compiler and cross compiles many free libraries such as SDL and Qt. Thus, it provides a nice cross compiling environment for various target platforms, which
| Runtime | Host Triplet | Packages |
|---|---|---|
| MinGW 3x | i686-pc-mingw32 | 301 |
| MinGW-w64 | i686-w64-mingw32 | 288 |
| x86_64-w64-mingw32 | 266 |
First, you should ensure that your system meets MXE's requirements. You will almost certainly have to install some stuff.
When everything is fine, download the current stable version:
git clone -b stable https://github.com/mxe/mxe.git
If you don't mind installing it in your home directory, just skip the following step and go straight to step 3.
MXE builds and installs everything under the same top-level directory and is not relocatable after the first packages are built.
Now you should save any previous installation of the MXE. Assuming you've installed it under /opt/mxe (any other directory will do as well), you should execute the following commands:
su mv /opt/mxe /opt/mxe.old exit
Then you need to transfer the entire directory to its definitive location. We will assume again you use /opt/mxe, but feel free to use any other directory if you like.
su mv mxe /opt/mxe exit
We're almost done. Just change to your newly created directory and get going:
cd /opt/mxe
Enter the directory where you've downloaded MXE. 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
Targets can also be specified on the command line. By default, only i686-pc-mingw32.static is built, but you can build your toolchain(s) of choice with:
make MXE_TARGETS='x86_64-w64-mingw32.static i686-w64-mingw32.static'
or by adjusting the MXE_TARGETS variable
in settings.mk.
You'll always end up with a consistent cross compiling environment.
If you have trouble here, please feel free to contact the mxe team through the issue tracker or mailing list.
After you're done it just needs a little post-installation.
Edit your .bashrc script in order to change $PATH:
export PATH=/where MXE is installed/usr/bin:$PATH
You may be tempted to also add $(TARGET)/bin
to your path. You never want to do this,
the executables and scripts in there will cause conflicts
with your native toolchain.
In case you are using custom $PKG_CONFIG_PATH entries, you can add separate entries for cross builds:
export PKG_CONFIG_PATH="entries for native builds"
export PKG_CONFIG_PATH_i686_pc_mingw32_static="entries for MXE builds"
Remember to use i686-pc-mingw32.static-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, $LDFLAGS, etc.) may spoil your compiling pleasure, so be sure to delete or disable those.
For the most isolated and repeatable environment, use a white-list approach:
unset `env | \
grep -vi '^EDITOR=\|^HOME=\|^LANG=\|MXE\|^PATH=' | \
grep -vi 'PKG_CONFIG\|PROXY\|^PS1=\|^TERM=' | \
cut -d '=' -f1 | tr '\n' ' '`
Congratulations! You're ready to cross compile anything you like.
If you use the Autotools, all you have to do is:
./configure --host=i686-pc-mingw32.static make
If you build a library, you might also want to enforce a static build:
./configure --host=i686-pc-mingw32.static --enable-static --disable-shared make
Don't worry about a warning like this:
configure: WARNING: If you wanted to set the --build type, don't use --host. If a cross compiler is detected then cross compile mode will be used.
Everything will be just fine.
If you have a CMake project, you can use the provided toolchain file:
cmake ... -DCMAKE_TOOLCHAIN_FILE=/where MXE is installed/usr/i686-pc-mingw32.static/share/cmake/mxe-conf.cmake
If you have a Qt application, all you have to do is:
/where MXE is installed/usr/i686-pc-mingw32.static/qt/bin/qmake make
Note that Qt 4 is in the "qt" subdirectory. Qt 5 is in the "qt5" subdirectory and its qmake can be invoked similarly.
If you are using Qt plugins such as the svg or ico image handlers, you should also have a look at the Qt documentation about static plugins.
Note the sql drivers (-qt-sql-*) and the image handlers for jpeg, tiff, gif and mng are built-in, not plugins.
If you have a handwritten Makefile, you probably will have to make a few adjustments to it:
CC=$(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.static-
That's it!
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.static-g++ \
-o osgstaticviewer.exe examples/osgstaticviewer/osgstaticviewer.cpp \
`i686-pc-mingw32.static-pkg-config --cflags openscenegraph-osgViewer openscenegraph-osgPlugins` \
`i686-pc-mingw32.static-pkg-config --libs openscenegraph-osgViewer openscenegraph-osgPlugins`
The i686-pc-mingw32.static-pkg-config command from MXE will
automatically add -DOSG_LIBRARY_STATIC to your compiler flags.
If you need further assistance, feel free to join the mailing list where you'll get in touch with the MXE developers and other users.
To obtain the current stable version, run:
git clone -b stable https://github.com/mxe/mxe.git
The development version can be obtained by:
git clone -b master https://github.com/mxe/mxe.git
N.B. when using the development version, ensure you use the local documentation (index.html) - the website reflects the stable branch.
To retrieve updates, run:
git pull
You can also browse the web repository.
In addition, feel free to join the mailing list and to propose new packages.
The following .git/config settings ensure
that the stable branch will always be pushed to the
gh-pages
branch in addition to the
stable branch,
thus ensuring the website will always stay in sync:
[remote "origin"]
url = git@github.com:mxe/mxe.git
fetch = +refs/heads/*:refs/remotes/origin/*
push = refs/heads/master:refs/heads/master
push = refs/heads/stable:refs/heads/stable
push = refs/heads/stable:refs/heads/gh-pages
[branch "master"]
remote = origin
merge = refs/heads/master
[branch "stable"]
remote = origin
merge = refs/heads/stable
For the sake of simplicity, there are just two branches, "master" and "stable". Although it might seem obvious, here's an overview of the types of changes that go into each branch:
And this is how the branches relete to each other:

Certain packages contain 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.
To build the remainder of MXE, specify the affected packages to exclude:
make EXCLUDE_PKGS='ocaml%'
All build commands also download the packages if necessary.
In a BSD userland, substitute "make" with "gmake" as all commands are based on GNU Make.
settings.mk
LOCAL_PKG_LIST := foo bar .DEFAULT local-pkg-list: local-pkg-list: $(LOCAL_PKG_LIST)
make will only build those packages (and their
dependencies, of course)
settings.mk and defaults to the number
of CPUs up to a max of 6 to prevent runaway system
load with diminishing returns - see the
GNU Make manual
for more details on parallel execution

The package should be a free software library that is really used by one of your applications. Please also review our legal notes.
BTW, we're always curious about the applications people are porting. We maintain a list of projects which use MXE. 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. :-)
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.
The GNU Make Standard Library is also available (though it should be unnecessary for most packages).
Adjust the comments,
fill in the $(PKG)_* fields.
To fill the $(PKG)_CHECKSUM field, use a command such as (for file gettext.mk):
make update-checksum-gettext
or:
openssl sha1 pkg/gettext-x.y.z.tar.gz
if you have already downloaded the package
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 MXE with make gcc only,
then check whether your package builds successfully.
Always list the dependency on gcc explicitly:
$(PKG)_DEPS := gcc ...
Add your package to the list of packages.
Each package gets its own table row element with table cells specifying your package name, official name and website:
<tr>
<td class="package">gettext</td>
<td class="website"><a href="https://www.gnu.org/software/gettext/">gettext</a></td>
</tr>
Always look for the SSL version of a website, that is,
prefer https:// URLs over http:// URLs.
Write your $(PKG)_BUILD.
If your library has a ./configure script,
enable/disable all dependency libraries explicitly
via "--enable-*" and "--disable-*" options.
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 MXE. See 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.
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.cor
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.
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 a placeholder:
define $(PKG)_UPDATE
echo 'TODO: write update script for $(PKG).' >&2;
echo $($(PKG)_VERSION)
endef
We'll fill that in for you. It's a funny exercise.
Check that you don't have "dirty stuff" in your *.mk files,
such as TAB characters or trailing spaces at lines endings. Run:
make cleanup-style
to remove these.
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.
When patching sources with crlf line endings, the patch
file itself should also have the same eol style. Use the
convention of naming the file as *crlf.patch
to instruct git not to normalise the line endings (defined
in .gitattributes).
Finally, in your $(PKG)_BUILD section,
please check that you use our portability variables:
bash | → | $(SHELL) |
date | → | $(DATE) |
install | → | $(INSTALL) |
libtool | → | $(LIBTOOL) |
libtoolize | → | $(LIBTOOLIZE) |
make | → | $(MAKE) |
patch | → | $(PATCH) |
sed | → | $(SED) |
sort | → | $(SORT) |
wget | → | $(WGET) |
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.
Issue a
pull request
to propose your final *.mk file to us.
If you have trouble with pull requests,
send your file to the mailing list instead.
Either way,
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.

Modern legal systems are like any other large, complex, and evolving body of code you're likely to encounter.
They have their own language with quirky parsers, compilers, and interpreters (though these tend to be human). Their issue trackers are a backlog of court cases. They have bugs. They have traps for the uninitiated that may potentially do more than waste your time.
We currently limit ourselves to:
--enable-languages='c,c++,objc,fortran'
so nothing mentioned here or on the mailing list should be taken as legal advice. :-)
The best starting point for any legal questions would be the
FTF (Freedom Task Force of the FSFE (Free Software Foundation Europe)).
They have been very helpful in the past, and maintain an extensive network of legal contacts, both within and outside Europe.
Your local jurisdiction may be a signatory to various international agreements, so be sure to mention where you are in any correspondence (much like any detailed bug report really).
Additionally, you should also do some background reading from the FSF (Free Software Foundation) and Wikipedia to familiarise yourself with some of the potential issues (and experience some context-switching overhead).
Contributions are always welcome!
Ownership of all contributions (bug fixes, new packages, doc updates, etc.) remain with the author. All we require is a real name (no l33t handles, please), and that you release your work under our licence.
If you prefer not to be credited with a contribution, please notify the committer.
Each package is individually licensed under terms specified by the authors of that package. Please see the respective source tarball and/or project website for details.
Packages that are non-free or ambiguous will be removed or rejected.
The definition of free must be one of:
Please contact the mailing list if you notice a package that doesn't meet these guidlines.
In addition to the usual considerations (copyrights, patents, trademarks, export regulations etc.), building statically linked libraries for Windows exposes some edge cases that you may not have encountered before.
According to freedom 0 and our own licence, you can use mxe in countless different environments, each with it's own special legal considerations. The configuration options of certain packages (e.g ffmpeg) allow the use of non-free software and/or combinations that cause license violations.
For these packages, we will provide sensible defaults aimed at achieving the following goals:
