Hi,
I can't get 6.2 to build -- it keeps failing on cddlib.
The log is attached, but I'm pretty sure the key part is:
/bin/bash ../libtool --tag=CC --mode=link gcc -g -O2 -L/usr/local/lib
-L/var/tmp/ddrake/sage/local/lib -o scdd_gmp simplecdd.o
../lib-src-gmp/libcddgmp.la -lgmp
libtool: link: gcc -g -O2 -o .libs/scdd_gmp simplecdd.o -L/usr/local/lib
-L/var/tmp/ddrake/sage/local/lib ../lib-src-gmp/.libs/libcddgmp.so
/var/tmp/ddrake/sage/local/lib/libgmp.so /usr/local/lib/libgmp.so -Wl,-rpath
-Wl,/var/tmp/ddrake/sage/local/lib
/usr/local/lib/libgmp.so: could not read symbols: File in wrong format
It looks like the linker is finding a system libgmp.so instead of the
one in Sage's tree. How do I get Sage to ignore it?
Hmmm, in spkg-install we meanwhile (only) have
export CPPFLAGS="-I$SAGE_LOCAL/include $CPPFLAGS"
export LDFLAGS="-L$SAGE_LOCAL/lib $LDFLAGS"
So probably we have to pass the location of GMP to 'configure' as well.
(For the previous version, 094f, Volker added a patch to let 'configure'
take '--with-gmp=...'.)
Although we apparently also patch all the Makefiles... (haven't looked
at those). And e.g. scdd, lcdd, redcheck etc. get linked correctly.
Jean-Pierre will know better.
