GNU Make question

[Rick]

I thought this was obvious...but meh
Here is what I want: I simply want to set a macro when the target 'server' is being build. That way a clean ded server can be build.
Here is what I have now, and doesn't work :-/

server: $(SERVER_OBJS)
	$(CXX) $(CXXFLAGS) -DSTANDALONE -o cube_bot_fbsd-server $(SERVER_OBJS) $(SERVER_LIBS)

For same reason the macro 'STANDALONE' is not set.

Can somebody please help me?

[Lazy]

Are you using the right macro?
Because this works for me...

dtest.c

#include <stdio.h>

int main( void ) {
	#ifdef _SERVER_
	printf( "Server started!\n" );
	#else
	printf( "Client started!\n" );
	#endif

	return 0;
}

Makefile

CC=gcc
CFLAGS=-O2
CLFILE=client.exe
SVFILE=server.exe

server:
	$(CC) $(CFLAGS) -o $(SVFILE) -D_SERVER_ dtest.c

client:
	$(CC) $(CFLAGS) -o $(CLFILE) dtest.c

clean:
	rm client.exe
	rm server.exe
	rm dtest.o

OK got it to work, thanks

I guess its the way of compiling...it works if I do it simulair to yours:

server:
	$(CXX) $(CXXFLAGS) -o cube_bot_fbsd-server -DSTANDALONE $(SERVER_FILES) $(SERVER_LIBS)

Where SERVER_FILES are the actual source files instead of the object files.

Not entirely sure if this is right...but I think the defines really only work compiling the source files direct, not on the object files - though header files are sometimes used when linking, so it could have an effect there.
I could be completely wrong - someone please correct me if I am!

I'm not sure about linking header files(never saw that happen), but you're right about the other part. Unfortunaly this way of compiling doesn't leave any .o files and thus you have to recompile everything each time.
