New description:
The 'prereq' script in {{{$SAGE_ROOT/spkg/base}}} is currently version
0.7. This does not check that the maths library {{{libm}}} exists. I
thought that was pretty much a formality, but it is not on AIX, where the
shared maths library {{{/usr/lib/libm.a}}} does not get installed by
default. This may also be the case on other operating systems, including
perhaps some cut-down Linux distributions, though I'm not aware of any
system other than AIX where the maths library does not get installed on a
basic installation of the operating system.
{{{
-bash-4.1$ ls /usr/lib/libm*
/usr/lib/libmbx.a
}}}
The maths library is part of the {{{bos.adt}}} fileset. Hence a test for
the maths library should be added. After installing {{{bos.adt}}}, so the
maths library exists:
{{{
-bash-4.1$ ls /usr/lib/libm*
/usr/lib/libm.a /usr/lib/libmbx.a /usr/lib/libm_r.a
/usr/lib/libmsaa.a /usr/lib/libmsaa_r.a
}}}
== Notes for reviewers ==
You will need to copy the {{{prereq-0.8.tar}}} from this ticket and the
{{{prereq-0.8-install}}} script from #11070 to {{{$SAGE_ROOT/spkg/base}}}
For the purposes of reviewing this ticket, you only need to look at the
changes to configure.ac.
== Notes for the release manager ==
This ticket must be merged with #11070, which also has positive review.
Each depends on the other. Some notes about the upgrade process are given
on #11070
