Add DESTDIR support for gap

[embray]

Implements #24024 for gap; this one is slightly non-trivial.

[jdemeyer]

Why not use sdh_configure here?

[embray]

Hmm, for some reason I thought it wasn't a standard autoconf configure, but it looks like it is, actually. I don't know why it's being passed some PREFIX argument. That doesn't seem to do anything.

Use sdh_configure; clean up some superfluous arguments to the configure script

(already merges without conflict with #23733)

This appears to have some kind of problem installing gap.sh...

Branch pushed to git repo; I updated commit sha1. New commits:

​b4ecda9	trac 23733: deprecate SAGE64 and CFLAG64
​905e4d4	Stop supporting SAGE64 except in Numpy
​4f85314	Merge branch 'u/jdemeyer/no-sage64' into u/embray/build/destdir-gap
​c14afaa	turns out bin/gap.sh is a symlink to either gap-default64.sh or gap-default32.sh (only one or the other should exist). rather than add explicit support for dereferencing symlinks, for now just copy the real file

Branch pushed to git repo; I updated commit sha1. This was a forced push. New commits:

​b03b468	Update to use sage-dist-helpers; add DESTDIR support where possible
​19a00c4	update package version for buildbot
​0a0ae72	Use sdh_configure; clean up some superfluous arguments to the configure script
​6d1493a	turns out bin/gap.sh is a symlink to either gap-default64.sh or gap-default32.sh (only one or the other should exist). rather than add explicit support for dereferencing symlinks, for now just copy the real file

[embray]

I think it should be good now.

[embray]

I believe this issue can reasonably be addressed for Sage 8.4.

[jdemeyer]

Since SAGE_GAP is no longer used in the script, it would be more clear to replace

SAGE_GAP="$SAGE_LOCAL/gap"
INSTALL_DIR="$SAGE_GAP/$GAP_DIR"

by

INSTALL_DIR="$SAGE_LOCAL/gap/$GAP_DIR"

[jdemeyer]

I would remove

[ -f bin/gap.sh ] || sdh_die "Error building GAP ('gap.sh' not found)."

You have a commit message turns out bin/gap.sh is a symlink to either gap-default64.sh or gap-default32.sh (only one or the other should exist). rather than add explicit support for dereferencing symlinks, for now just copy the real file. I would rather see something like that in a comment in the script, otherwise it's quite obscure what sdh_install -T bin/gap-default*.sh "$SAGE_LOCAL/bin/gap" does.

Given that we have sage-legacy-uninstall, shouldn't this be moved there?

rm -rf "$INSTALL_DIR"
rm -f "$SAGE_LOCAL/gap/latest"
rm -f "$SAGE_LOCAL/bin/gap"

(just a question, if there is a good reason to keep it there: fine for me)

Replying to jdemeyer:

rm -rf "$INSTALL_DIR"
rm -f "$SAGE_LOCAL/gap/latest"
rm -f "$SAGE_LOCAL/bin/gap"

Yes, this ticket just predates that being merged; as long as this is still open it makes sense to go ahead and move that stuff into an spkg-legacy-uninstall.

​ee25fe7	move the old cleanup code to an spkg-legacy-uninstall

[embray]

Done all of the above.

[embray]

Bump.

[embray]

This is also implemented by #22626 which supersedes this.
