Re: [Gcl-devel] Fwd: Patch for gcl-2.6.7 on MacOSX(10.4.2) to build maxima-5.9.[12] and so on.

[Aurelien Chanudet]

Hi all,

I've fixed most compilation issues (see attached patches ; I may have
forgotten some).

Just some issue concerning symbol mangling : although C symbols on
Darwin are prepended by leading underscore, it does not appear to be
possible to refer directly to _getc (in plt.h). getc (without the
leading underscore) should be used instead.

Can someone contribute back to the binutils maintainers the code in
mach-o.h, mach-o.c and mach-o-reloc.c ?

I get the following error :

my_free and my_malloc are defined in o/alloc.o, which apparently isn't
supplied to the linker. What's the best way to fix this ?

Thanks & regards,
Aurelien
