make[2]: *** [libutil/mipmap.o] Error 1
make[1]: *** [default] Error 2
make: *** [default] Error 2

the errors all seem to be related to malloc issues.  This code is the first error:

    beforeImage =
        malloc(image_size(widthin, heightin, format, GL_UNSIGNED_SHORT));

It appears that darwin and/or gcc 4.0.1 really don't like converting the
unsigned short* to a void* but I'm not sure how to go about fixing it.

Comment 1 Benjamin Reed 2006-06-10 08:09:01 UTC

OK, it looks like the issue is the C code is being compiled with C++

Darwin is the only platform with "CC = c++" and I *suspect* it's because at some
time in the past someone did that because of issues linking c++ libraries.

However, it appears that's not necessary, as the mklib call makes sure that CXX
is called for the linker:

$(LIB_DIR)/$(GLU_LIB_NAME): $(OBJECTS)
   $(TOP)/bin/mklib -o $(GLU_LIB) -linker '$(CXX)' \
      -major $(GLU_MAJOR) -minor $(GLU_MINOR) -patch $(GLU_TINY) \
      -cplusplus $(MKLIB_OPTIONS) -install $(LIB_DIR) \
      $(GLU_LIB_DEPS) $(OBJECTS)


I'm testing right now, but I bet that's the issue.

Yes, same issue as #7174, please put additional comments there.
