compile GNU/Linux binaries in Windows

[Whistler]

... It's just possible, this is what you need

It's actually just a mere build of the MinGW source code with some extra configs, as MinGW and GNU/Linux version of gcc are actually the same code.

binaries can be compiled ?
what is this program doing ?
Does it compile source code ? If so, does it have support for SUSv3 or LSBSv2.01 under windows ?

[Whistler]

it's just a GCC built under Windows in this way:
./configure --prefix=c:/gcc-gnulinux --target=i686-pc-linux-gnu
make
make install

Actually MinGW and *NIX gcc are the same code, this just enabled the GNU/Linux compiling instead of default MinGW Windows compiling. It should compile the same as GNU/Linux, but perhaps you need some extra libraries to compile something other than bots.

Can it do cross-compiles? I'd be interested in compiling native Linux binaries for my metamod stuff without needing to upload my sources each time on the BU server.

[sPlOrYgOn]

I just tried it with pbmm but it seems to create a .so file twice the size of when it is compiled on linux and also gets a badf load...
can i compile on the BU server too?

[Pierre-Marie Baty]

Anybody who has a shell account on the BU machine can compile his plugins... but I think you don't have one yet because you don't have any website for your bot. One more reason to change that

[Whistler]

well I've found the problem... try NOT to use "-march" parameter (like -march=i586 or so) and use "_i386.so" as the end of the filename and it should work in Metamod

also note that "gcc" is the C compiler, and "g++" is the c++ compiler so make sure you are compiling C++ code with "g++" command.

but the file size is still big, as it's totally staticly linked.

[Whistler]

well you also need to use the "-static" parameter...

here's the work Makefile

PHP Code:

CPP = g++
TARGET = podbot_mm
BASEFLAGS = -Dstricmp=strcasecmp -Dstrcmpi=strcasecmp
OPTFLAGS = -DNDEBUG
CPPFLAGS = ${BASEFLAGS} ${OPTFLAGS} -O2 -w -I"../metamod-1.17/metamod" -I"../hlsdk/multiplayer/common" -I"../hlsdk/multiplayer/dlls" -I"../hlsdk/multiplayer/engine" -I"../hlsdk/multiplayer/pm_shared"

OBJ =     bot.o \
    bot_chat.o \
    bot_client.o \
    bot_combat.o \
    bot_globals.o \
    bot_sounds.o \
    compress.o \
    dll.o \
    engine.o \
    util.o \
    waypoint.o

${TARGET}_i386.so: ${OBJ}
    ${CPP} -fPIC -shared -static -o $@ ${OBJ} -ldl -lm

clean:
    rm -f *.o
    rm -f *.map

%.o:    %.cpp
    ${CPP} ${CPPFLAGS} -c $< -o $@

%.o:    %.c
    ${CPP} ${CPPFLAGS} -c $< -o $@ 


looks like it's still far from being perfect

Works fine, thanks!

btw, I've just found another similiar way to compile win32 binaries from linux 8D:

[Pierre-Marie Baty]

Yes, and I believe that's what Will Day does with metamod, he compiles everything on GNU/Linuts
