hicolor-icon-theme is not necessary as gtk3 pulls it in. pcre is not necessary as it's required by grep which is in the base-devel group.

Tags are available, please use:

pkgver() {
    cd $_gitname
    printf "%s" "$(git describe --long --tags | sed 's/\([^-]*-\)g/r\1/;s/-/./g')"
}

pkgver=0.1beta2.r155.fcf10b8

The PREFIX=/usr make flag is not necessary.

Please use consistent indentation.

@TrialnError, thx, fixed.

Adding autoconf and libtool to makedeps isn't necessary.
All packages from base and base-devel are a requirement for the AUR and those packages aren't added to the deps lines

Edit: and pkg-config

@johnnydvc, yeah but otherwise yaourt can't build projects from the AUR. You have to be able to execute stuff like autogen.sh or configure. Maybe there's a way how to tell yaourt to build in a different directory, but it definitely needs the ability to execute scripts.

@wander, I think that might be it. I'll try to mount without noexec.
But that's generally not a good idea.

@johnnydvc, can you post the complete build log? And can you please try to manually execute the autogen.sh script?

It seems like autogen.sh can't be executed, which is pretty strange. Maybe the execute flag is missing, or you mounted /tmp with noexec option?

Sorry, still not building.
Same error message.

Hi,
I just updated the build dependencies. Can you try it again?

Hi, I cannot build it.
... no permission while auto generating
any ideas?

/tmp/yaourt-tmp-e/aur-fsearch-git/./PKGBUILD: Zeile 24: ./autogen.sh: Keine Berechtigung

I'm glad I could be of help :-)
