Re: [Fink-users] GMP C++ shared lib

[Fred Mesnard]

Hi Justin, hi Martin,

Here are some more info:

I have installed Mac OS X 10.2 + the developer CD + the august update from Apple:
% what /usr/bin/libtool
/usr/bin/libtool
PROGRAM:cctools_misc PROJECT:cctools-435 DEVELOPER:root BUILT:Mon Jul 15 20:25:50 PDT 2002

I don't have Fink installed, I'm waiting for the next version.
I add:
% set CPPFLAGS=-fexceptions
% echo $CPPFLAGS
-fexceptions
%

I configure GMP 4.1 with the --enable-cxx option. No problem, I think. Then I do a make:
... everything seems to compile fine until :
scanf/fscanffuns.o scanf/scanf.o scanf/sscanf.o scanf/sscanffuns.o scanf/vfscanf.o scanf/vscanf.o scanf/vsscanf.o
ranlib .libs/libgmp.a
creating libgmp.la
(cd .libs && rm -f libgmp.la && ln -s ../libgmp.la libgmp.la)
/bin/sh ./libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I. -D__GMP_WITHIN_GMP -g -O2 -mpowerpc -no- cpp-precomp -mcpu=750 -c -o dummy.lo `test -f dummy.cc || echo './'`dummy.cc

Any suggestion?
