compile GNU/Linux binaries in Windows

[The Storm]

Can someone explain me how to compile with this EPB. It will be good to have a linux version.

[sfx1999]

So, how do I cross compile for the PDP-11?

"Can someone explain me how to compile with this EPB. It will be good to have a linux version."
just create a file named "Makefile" in your source directory, like this one:

PHP Code:

 CPP = g++
TARGET = epb
BASEFLAGS = -Dstricmp=strcasecmp -Dstrcmpi=strcasecmp
OPTFLAGS = -DNDEBUG
CPPFLAGS = ${BASEFLAGS} ${OPTFLAGS} -O2 -w -I"./hlsdk"

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 $@ 


(note that you MUST have a backslash after each ".o" file; the forum has bugs which ate up all backslashes)

write all your .cpp files in the list, change all .cpp to .o.

Then install the compiler, start a DOS prompt, run the setvars.bat file first and change into your source dir. Then run "make" and it should produce a epb_i386.so file and that's it.

I wonder what it would be like with the [ code ] tags instead...

CPP = g++ 
TARGET = epb 
BASEFLAGS = -Dstricmp=strcasecmp -Dstrcmpi=strcasecmp 
OPTFLAGS = -DNDEBUG 
CPPFLAGS = ${BASEFLAGS} ${OPTFLAGS} -O2 -w -I"./hlsdk" 
 
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 $@

*edit* damn, yer right.
I'd better look into that someday.

It's not working :
here is the error messege:
make : <e=2>:
make : *** [EPB_i386.so] Error 2

[Whistler]

in which step this error happened? would you post the full output?

(also you need to add the log.o to the list in Makefile if you haven't deleted it, and if you've created new files you need to add them as well)

[The Storm]

Here :

dll.cpp:20: error: expected `>` before '*' token
dll.cpp:20: error: expected `,` or `;` before '*' token
dll.cpp:22: error: expected `>` before '*' token
dll.cpp:22: error: expected `,` or `;` before '*' token
dll.cpp:29: error: `GETNEWDLLFUNCTIONS` does not name a type
make: *** [dll.o] Error 1

The strange is that when I compile it with MSVC there is no problem.

[Whistler]

then it's bacause something GNU/Linux specific is missing in the code... you gotta fix it first
search for "__linux__" in HPB bot and you'll see what's required

edit: I think this is the problem:

PHP Code:

// stuff for Win32 vs. Linux builds

#ifndef __linux__

typedef int (FAR *GETENTITYAPI)(DLL_FUNCTIONS *, int);
typedef int (FAR *GETNEWDLLFUNCTIONS)(NEW_DLL_FUNCTIONS *, int *);
typedef void (DLLEXPORT *GIVEFNPTRSTODLL)(enginefuncs_t *, globalvars_t *);
typedef void (FAR *LINK_ENTITY_FUNC)(entvars_t *);

#else

#include <dlfcn.h>
#define GetProcAddress dlsym

typedef int BOOL;

typedef int (*GETENTITYAPI)(DLL_FUNCTIONS *, int);
typedef int (*GETNEWDLLFUNCTIONS)(NEW_DLL_FUNCTIONS *, int *);
typedef void (*GIVEFNPTRSTODLL)(enginefuncs_t *, globalvars_t *);
typedef void (*LINK_ENTITY_FUNC)(entvars_t *);

#endif 


and it seems that in POD-Bot the GETNEWDLLFUNCTIONS isn't declared after the #else.

Thanks you Whistler. You was write ! The problem was in bot.h.
Now I succseful compile EPB for Linux. With the next release I will publish and the Linux version of EPB.
Thnaks you again.

EDIT : Did I must publish the source code of EPB if I publish a Linux version ?

[Whistler]

"Did I must publish the source code of EPB if I publish a Linux version ?"
Nope, as you are just *USING* gcc, which is totally free and not restricted
perhaps you can read through the GPL to see in which case you need to release the sources.
