Does this imply you get no other failures? Even close to that would be
great news.
I have four other errors, which are all floating point errors, and it is
debatable whether they are failures.
I'm curious how many of the patches in tickets in the FreeBSD component
[1] you actually need with 5.1.beta5 in order for Sage to be a-ok.
I did not use #5873, #7831, #9606, #12059. All the others I used.
I used a work around for #9606, which I will describe below.
Is there anyone out there who can help review those? It would be really
helpful to know which of those can be closed, and which ones could be
merged, though it would be good to have two sets of eyes on those who
actually understand such build systems. That would make one not need the
"port" concept, though naturally that would be good to have too (if it
is something that uses some system components like Sage-on-Gentoo).
If you want to avoid using a FreeBSD port, you are going to have to
incorporate something like this:
FreeBSD allows for the user to use several different versions of cc
(including clang). It uses gcc-4.6 by default whenever a fortran
program is required.
For this reason, I created my own versions of cc, c++, gfortran, etc,
and sh, in $SAGE_ROOT/bin. sh was merely a link to /usr/local/bin/bash
(hence no need for #9606). For cc, etc, I placed a script something like:
#!/bin/sh
if [ "x$*" = "x-v" ]; then
exec /usr/local/bin/gcc46 "$@"
else
exec /usr/local/bin/gcc46 \
-Wl,-rpath=/usr/ports/math/sage/work/sage-5.0.1/local/lib \
-Wl,-rpath=/usr/local/lib/gcc46 \
"$@"
fi
Can you check if Trac 13134 [2] fixes it?
I got a whole different set of errors:
