Wish: Cross compiling

[mihaim]

Did anyone tryed to do a cross compile ? If yes can anyone post a mini howto .... if not can someone look into it ?

 

It will be really nice to have clients cvs build up to date ....

 

So anyone wants to dig up in this ?

[Entropy]

For win32 you mean?

[mihaim]

Yep . Building win32 client from linux. Lots of advantages if we can do this .

A first shot in the dark, will try it later.

I have built a windows version of a bot once, using the mingW compiler on linux. I used the instructions on http://www.libsdl.org/extras/win32/cross/README.txt to install the cross-compiler.

I tried that, but didn't have the patience with the client...

Error 404: Not Found

 

when executing the first shellscript

 

So ill try to follow the instructions i posted now.

Ok, another link:

 

http://members.lycos.co.uk/alexv6/Cross_mi...sing_HOWTO.html

 

This one gave me already a HELLO.EXE which works both under Linux and Windows

 

Its easy to use, just read, download, extract into the named directories, execute once a script named cross by typing ". cross" once you logged on and compile using gcc.

 

For make there is a cross-make and a cross-configure is available too.

Or use Wine

[Malaclypse]

I managed to compile a windows binary using a mingw cross compiler Unfortunately I can not test it yet Anyone, I can send the binary to for testing?

[The_Piper]

Yes, me.

 

I sent you my email addy as a forum mail.

 

Im actually trying too to compile something more than a hello.exe. Let see how far we can go :lol:

 

Piper

[The_Piper]

Unbelievable, it works

 

Of course, i must compile with -DNO_MUSIC, but this seems to be my personal curse...

 

So, to cross compile, do this:

 

http://members.lycos.co.uk/alexv6/Cross_mi...sing_HOWTO.html

 

Follow the instructions in this link, download and install the software in the recommended directories and create that link /target.

 

Then follow the instructions in the "how to compile with dev-cpp" pinned post in the Programming forum. Meaning, install all the include and lib files to the /target/include and /target/lib directories as described in that post. And copy the OpenAl files too into the include and lib dirs. Unfortunately you need windows to execute the setup.exe for openal...

 

Then save this makefile as Makefile.cross. You must replace [tab] with real tabulators. Its based on a Makefile a player Ohmu posted some month ago in forums.

CXXFLAGS =  -I"$(DEV-MAIN)" -I"$(ICONV)" -I"$(LIBXML)" -I"$(SDL)" -I"$(OPENAL)" -I"$(OGG)" -I"$(VORBIS)" -DNO_MUSIC -DWINDOWS -march=i686 -fomit-frame-pointer -ffast-math -pipe -fexpensive-optimizations -O -DELC 
CFLAGS = $(CXXFLAGS) 

all: $(OBJECTS)
[tab]$(CC) -o "$(OUTPUT)" $(OBJECTS) $(LIBS)

$(ELC-RES):
[tab]$(WINDRES) -i elc_private.rc -I rc -o $(ELC-RES) -O coff

clean:
[tab]rm -f $(OBJECTS) $(OUTPUT)

 

Then simply go to your ELC directory and type "cross-make -f Makefile.cross" and thats it.

 

The result is named elc_cross.exe.

And another makefile which cross-compiles a client with music.

 

I added 2 more vorbis libs to solve that problem.

 

If you take the latest source from CVS and cross-make -f you get errors about some arc() functions. It seems that the math.h file from mingcc is wrecked, so simply remove #include <math.h> from those files where the errors with arc() occur.

 

Then it compiles fine both on Linux and Windows.

 

Erm, and you must replace [tab] in the makefile with real tabulators, of course.
