Hi David,

I am trying to get the OS X version to run from a clean CVS trunk (i have backed-up my previous version). you did a lot of changes, and i rather try to get the current CVS trunk to run correctly on OS X and create a patch from there instead going from a 2 month old version.

currently I hit a wall as soon as i try to make dtool.

cd ./src/dtoolbase && make all
cc   -c -o Opt2-osx/dtoolbase_dlmalloc.o -I. -I/Users/kaweh/Projects/panda3d/dtool   -D_DEBUG -Wall -g -O2 -fPIC dlmalloc.c

collect2: ld returned 1 exit status
make[1]: *** [Opt2-osx/libdtoolbase.dylib] Error 1
make: *** [dtoolbase] Error 2

i also know what the problem is. if we look at dtool/scr/dtoolbase/Makefile lines 37-38 it says:

Opt2-osx/libdtoolbase.dylib : $(libdtoolbase_so) 
	 CC -shared  -o Opt2-osx/libdtoolbase.dylib $(libdtoolbase_so) -L/usr/local/panda/lib

now this is wrong on OS X. to link correctly it needs to say

Opt2-osx/libdtoolbase.dylib : $(libdtoolbase_so) 
	 g++ -dynamiclib  -o Opt2-osx/libdtoolbase.dylib $(libdtoolbase_so) -L/usr/local/panda/lib

i assume this is because ppremake is using the unix template for generating the Makefile… i don’t see a OS X template. calling CC on C++ code is also odd as far as i can tell.

do you know which *.pp file i should try to fix and see if i can get the current clean CVS trunk to build correctly?

thanks,
kaweh
