I'm not applying the second patch for now.
It would be good if this Macaulay2 could be made to rebuild Singular in
this case. Perhaps have an environment variable that determines if those
two targets are built or not.
{{{
build()
{
patch
distclean
config
build_singular
build_libsingular
if [ "x$SAGE_USING_Macaulay2" = xyes ] ; then
build_factory
build_libfac
fi
create_singular_script
install_docs
}
}}}
Then ensure Macaulay2
* exports SAGE_USING_Macaulay2 = "yes"
* Rebuilds Singular. This time build_factory & build_libfac would built,
due to the environment variable being set to "yes"
I guess this depends on the popularity of Macaulay2. If 20% of people
install it, then we might as well build all targets. If however only 1% of
people install Macaulay2, then I doubt it warrants slowing the build
process for everyone.
Currently I believe Singular is the slowest package to build in Sage (at
least on my !OpenSolaris machine), though neither R or Maxima are
building, so I can't say for sure. But Singular definately takes a long
time to build, so if that could be improved, it would be nice. Of course,
it depends on how long those targets take to build. If the savings from
not building them are only small, we might as well build them.
Another option might be to let an environment variable be used to stop
those two targets building, but by default build them all.
