giac-1.7.0.13-r1 fails install phase on Prefix

It looks like a double prefix of sorts. The Exemples folder is located under

/storage/strogdon/gentoo-rap/var/tmp/portage/sci-mathematics/giac-1.7.0.13-r1/image/usr/share/giac/doc/

And under my prefix's image folder there is

ls /storage/strogdon/gentoo-rap/var/tmp/portage/sci-mathematics/giac-1.7.0.13-r1/image
storage  usr

Just realized giac-1.7.0.13-r1 is a portage, not s-o-g, package.

Not a solution to the Prefix issue but do you have on Gentoo under /usr/share

/usr/share/giac
/usr/share/giac.backup.0000

Here /usr/share/giac is empty and /usr/share/giac.backup.0000 is a symlink to /usr/share/doc/giac-1.7.0.13-r1. I'm guessing that /usr/share/giac was a holdover from a previous install. Removing /usr/share/giac, the backup symlink and reinstalling giac seems to look better - /usr/share/giac is now a symlink to /usr/share/doc/giac-1.7.0.13-r1.

I actually do have /usr/share/giac.backup.0000 and it is a dead link to doc/giac-1.7.0.13-r1. I have 1.7.0-43 currently installed and I don't remember if I imported all the changes of the main tree regarding the doc. There is an issue that some of the manual is under a non-free license and shouldn't be redistributed the way we do. The other issue is that by default the doc is not installed in the right spot according to Gentoo policies. The link is because it is difficult to patch the right location inside giac, so a pointer was left.

[strogdon]

I think so. I have proposed a fix at https://bugs.gentoo.org/829385 on Prefix that now behaves like Gentoo, i.e.

EPREFIX/usr/share/giac is a symlink to EPREFIX/usr/share/doc/giac-1.7.0.13-r1 where the compressed docs are installed.

I'll close this. Fixed with https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=ecc4a10ede9f57abd1770d5c6ac20184ec317fa6
