First off, this patch creates a syntax error. On 25.12.2011 07:52, Allan McRae wrote:
- Only calculates the version for libraries specifically requested and not all libraries. This has the disadvantage of running find over the $pkgdir for as many libraries as needed, but is unlikely to be an issue due to caching.
Maybe you could create a search string like the following? This won't preserve the order, but it will traverse the file system only once and according to the find manpage it's POSIX compliant. find /usr/lib -type f \( -name libx264.so\* -o -name libc.so\* -o -name libarchive.so\* \)
- The order of the provides array in the PKGBUILD is kept in the package - There are more warning messages when things fail and those that were there are no longer errors (as I do not think failure of libprovides should result in complete packaging failure)
I think it should because libraries hardly move between packages or change their names and the packager might not see the message and push a package with incorrect provides. It might be a good idea not to abort right away though. You could check all entries and abort later, but I think you shouldn't create a package since the packager will have to fix the incorrect entry and rebuild/repackage anyway.
- It is now modular so can be easy extended to other library types other than ELF *.so.

This else block doesn't have any matching if statement. The one with "Library listed in %s is not a shared object" already closes 'if LC_ALL=C readelf -h "$fn" 2>/dev/null | grep -q '.*Type:.*DYN (Shared object file).*'; then' -- Florian Pritz
