Comment(by fbissey):
I noticed that you have mpfr in the dep for lcalc and that you include
mpfr in the library list in module_list.py for the lcalc extension as
well.
lcalc doesn't currently depend on mpfr or link against it.
I checked the current spkg and the latest version included in this bug
and neither does. In spkg-install you have
{{{
if [ "$UNAME" = "SunOS" ]; then
LCALC_LIBS="-lpari -lmpfr -lgmpxx -lgmp -liberty"
else
LCALC_LIBS="-lpari -lmpfr -lgmpxx -lgmp"
fi
export LCALC_LIBS
echo "Using LCALC_LIBS=$LCALC_LIBS"
}}}
But LCALC_LIBS is not used anywhere in either the original Makefile
or the Makefile provided by sage.
I think it is a remnant from a time where Dave (Kirby) had an extremely
simplified Makefile for lcalc and even then it was a case of overlinking.
If you want to use mpfr in lcalc you need to export
{{{
PREPROCESSOR_DEFINE=-DUSE_MPFR
}}}
and on my machine at least lcalc refuse to compile with this.
