I think this may have been working somewhat of by accident before, because it says 'extern "C"' in one place and in another say '// sorry, if you want a C version, feel free to add it'
I delayed a bit sagemath 6.4 update due to some dependencies needing to be updated in Fedora, in the meantime 6.4.1 was released. Trying to update to Fedora sagemath rpm to 6.4.1 I am being hit by this: ---%<--- File "/home/pcpa/rpmbuild/BUILDROOT/sagemath-6.4.1-1.fc22.x86_64/usr/lib64/python2.7/site-packages/sage/libs/ntl/__init__.py", line 1, in <module> import all File "/home/pcpa/rpmbuild/BUILDROOT/sagemath-6.4.1-1.fc22.x86_64/usr/lib64/python2.7/site-packages/sage/libs/ntl/all.py", line 34, in <module> from sage.libs.ntl.ntl_ZZ_p import ( ImportError: /home/pcpa/rpmbuild/BUILDROOT/sagemath-6.4.1-1.fc22.x86_64/usr/lib64/python2.7/site-packages/sage/libs/ntl/ntl_ZZ_p.so: undefined symbol: ZZ_p_to_int error: Bad exit status from /var/tmp/rpm-tmp.moMkJq (%install) ---%<--- Previously it was exported as a "C" symbol: $ rpm -q sagemath sagemath-6.3-3.fc22.x86_64 $ objdump -T --demangle /usr/lib64/libcsage.so | grep ZZ_p_to_int 0000000000008760 g DF .text 0000000000000005 Base ZZ_p_to_int But the newly generated libcsage.so does only show a C++ symbol: $ objdump -T --demangle BUILD/sage-6.4.1/src/c_lib/libcsage.so | grep ZZ_p_to_int 00000000000087d0 g DF .text 0000000000000005 Base ZZ_p_to_int(NTL::ZZ_p const&) So, it may be required some extra wrapping, but more likely, patch the cython code to only use ZZ_to_int(ZZ*). This may also be useful... $ rpm -q gcc binutils gcc-4.9.2-1.fc22.x86_64 binutils-2.24-29.fc22.x86_64 Thanks, Paulo -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
