Crosscompiling with tdragon's gcc

[imbaczek]

Found this little gem during the weekend: http://www.profv.de/mingw_cross_env/. After dropping the author an email, he said he always wanted a more recent gcc, but didn't know about tdragon's, so the day after support was there. Installation: untar, make, done (it downloads sources itself), and it even crosscompiles boost! (for tdragon support you need to grab hg clone, it's not released yet.)

hmm.. this is usefull for unix distors with poor packaging systems, or simply no mingw packages by default?
or what would be good for us, about this?

[imbaczek]

we can have a gcc that doesn't suck, need to poke bibim when he's back.

[hoijui]

so we would have a better MinGW. like.. later version, more gcc like/compatible... things like that?

[imbaczek]

yeah, my main interest is debug symbols that actually work with gdb, but the optimizer improvements are worth it too, imho.

edit: i finished the spring crosscompilation and it works flawlessly. scons script for future reference:

Code: Select all

#!/bin/sh
#sconscross.sh

export MINGDIR=$HOME/usr/mingw_cross_env/usr/
export CC=$HOME/usr/mingw_cross_env/usr/bin/i386-mingw32msvc-gcc
export CXX=$HOME/usr/mingw_cross_env/usr/bin/i386-mingw32msvc-g++
export AR=$HOME/usr/mingw_cross_env/usr/bin/i386-mingw32msvc-ar
export RANLIB=$HOME/usr/mingw_cross_env/usr/bin/i386-mingw32msvc-ranlib

scons $* platform=windows

would've used cmake but no idea how to force crosscompilation there ^^

would've used cmake but no idea how to force crosscompilation there ^^

You could have checked the wiki:

# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)

# which compilers to use for C and C++
SET(CMAKE_C_COMPILER i686-mingw32-gcc)
SET(CMAKE_CXX_COMPILER i686-mingw32-g++)

# here is the target environment located
SET(CMAKE_FIND_ROOT_PATH /usr/i686-mingw32)

SET(MINGWLIBS /home/karl/spring/mingwlibs_v12)

Code: Select all

Pass this with "-DCMAKE_TOOLCHAIN_FILE=/your/toolchain/file" to cmake or select it in the gui to make a cross-compilation.

was looking in cmake docs, dunno what i missed, but it doesn't matter; it works and that's ok.

also, it doesn't crash like the builds from buildserv.

Do we have working buildbot yet? Or a binary for Windows?

[imbaczek]

i compiled one using my own crosscompiling setup, here it is: http://www.darkstars.co.uk/downloads/vi ... 136ac0.zip

seems to work fine.

[Argh]

Thanks so much, that will be veeeeeery useful.

[Argh]

Says it can't run, something about boost_thread-mgw43-mt-1_36.dll... crap.

[imbaczek]

forgot a dll. lemme see...

[Argh]

Sorry to be such a pain, I've just been dying to get a current build running...

[imbaczek]

these are the missing dlls: http://www.darkstars.co.uk/downloads/vi ... ost136.zip

Doesnt #buildserv offer the latest binaries as well? I recall it doing so.
Also, if you wanna compile it on windows with vs2005, shoot me a pm.

[imbaczek]

the problem is buildserv's binaries are broken for quite some time now.

[hoijui]

why iam i trying to get my branch running on buildserv then!?!?

BIBIM!!!!!!!!!!!!!!!

[imbaczek]

your branch may be fine as you didn't merge master for quite some time. compiling works, btw ;p

[Argh]

It's working over here. Horrible graphics errors with the trees and other issues, but I'll live.
