[aur-general] How to handle installers in PKGBUILDs

[Michael Schubert]

Hi,

I am already maintaining a couple of PKGBUILDs and wanted to add one
for CellDesigner, which is used to model biochemical pathways. The download
is only available as binary package with its own installer.

Now, I thought that I could use the installer inside a PKGBUILD with $pkgdir
as root. However, the installer cross-references some files in others with
absolute paths, i.e. when the package is installed it still links to the
build dir instead of the system dir. Because of the way the cross-refs are
inserted, simple sed'ing these does not work.

The obvious solution would be to use fakeroot/chroot in the $pkgdir and use
to to emulate a root directory structure. My question now is: (1) am I on
the right track and (2) is there any standard way to do this in PKGBUILDs?

I couldn't find any sample PKGBUILDs concerning this issue and the ArchWiki
contains no information either.
Any help would be appreciated.

Cheers, Michael
