Re: GNUstep-make and C++ projects...

[Jiva DeVoe]

Here's the output of that command:

$ make CC=g++ messages=yes
Making all for ctool LogTest...
g++  -rdynamic       -o shared_obj/LogTest \
                 \
	       -L/home/jiva/GNUstep/Library/Libraries -L/usr/local/lib/ 
GNUstep/Local/Library/Libraries -L/usr/local/lib/GNUstep/Network/ 
Library/Libraries -L/usr/lib/GNUstep/System/Library/Libraries -lm
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/crt1.o: In function  
`_start':
../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status
make[1]: *** [shared_obj/LogTest] Error 1
make: *** [LogTest.all.ctool.variables] Error 2

If you look there, mine is missing the source.cc in there.  Maybe  
something with my makefile... again here that is:

include $(GNUSTEP_MAKEFILES)/common.make

CTOOL_NAME = LogTest
LogTest_CC_FILES = source.cc

include $(GNUSTEP_MAKEFILES)/ctool.make


I'm using the debian packages... could it be something broken with  
those?

BTW, I notice I *have* to name my Makefile GNUmakefile... is it  
possible to just name it Makefile and have it work?
