-= Instructions for cross-building UQM =-
|
|
|
|
|
|
Terminology:
|
|
Build system
|
|
The system on which the code is being built.
|
|
Host system
|
|
The system on which the code is supposed to run on.
|
|
|
|
|
|
Set the environment variable 'CROSS_ROOT' to the root of your cross building
|
|
environment. This is not necessary for the build scripts, but it will
|
|
simplify what you type in the following steps.
|
|
|
|
Make sure your cross-building tools (gcc, ld, etc) are in the path.
|
|
export PATH=$CROSS_ROOT/bin:$PATH
|
|
Make sure that it isn't being reset by subshells that are started.
|
|
unset ENV BASH_ENV
|
|
|
|
Set the environment variable 'BUILD_HOST' to the host system.
|
|
This is whatever 'uname -s' returns on such a system (like "MINGW32").
|
|
When building for Windows CE, using the cegcc tools, you should use "cegcc".
|
|
|
|
If your host system is big-endian, set the environment variable
|
|
'BUILD_HOST_ENDIAN' to "big". For a little-endian system, you don't
|
|
have to do anything.
|
|
export BUILD_HOST_ENDIAN=little
|
|
|
|
If you're using pkg-config (advised), set the environment variable
|
|
PKG_CONFIG_PATH' to the pkgconfig directory of the cross environment.
|
|
This dir normally resides in the 'lib/' directory.
|
|
export PKG_CONFIG_PATH=$CROSS_ROOT/lib/pkgconfig
|
|
|
|
For any libraries that can't be detected - which will be a lot if you
|
|
don't use pkg-config - set the corresponding include dirs in CFLAGS and
|
|
library dirs in LDFLAGS.
|
|
export CFLAGS="-I$CROSS_ROOT/include"
|
|
export LDFLAGS="-L$CROSS_ROOT/lib"
|
|
|
|
Run configure:
|
|
./build.sh uqm config
|
|
This will produce the file 'build.vars' and 'config_unix.h' (or config_win.h
|
|
on MinGW or Cygwin). If there are any problems during the build, you can
|
|
usually easilly solve them by editing these files manually.
|
|
|
|
Start the compilation:
|
|
./build.sh uqm
|
|
|
