Hello,
The current LinBox? package in Sage 2.8.2 has the following assignments in spkg-install
CFLAGS="$CFLAGS -fPIC -I\"$SAGE_LOCAL/include\" -I\"$SAGE_LOCAL/include/linbox\"-L\"$SAGE_LOCAL/lib\""
CXXFLAGS="$CXXFLAGS -fPIC -I\"$SAGE_LOCAL/include\" -I\"$SAGE_LOCAL/include/linbox\" -L\"$SAGE_LOCAL/lib\""
CPPFLAGS="$CPPFLAGS -I\"$SAGE_LOCAL/include/linbox\" -I\"$SAGE_LOCAL\"/include"
but uses the configure with the following options:
./configure --prefix="$SAGE_LOCAL" --with-givaro="$SAGE_LOCAL" --with-gmp="$SAGE_LOCAL" --with-ntl="$SAGE_LOCAL" $OPS --with-blas="$LINBOX_BLAS"
This is due to a bug in LinBox? where for exmaple GMP_CFLAGS is not propagated down into the Makefiles (via Makefile.am). I have fixed this for the GMP and I assume that it is the same fix for NTL and Givaro. The GMP fix already made it into LinBox?-20070814.spkg and I did verify on my systems that the right gmp selected during configure is also linked against. Once I have made the fixes for NTL and Givaro I will push those fixes toward LinBox? upstream.
Cheers,
