Arch Linux User Repository

Note: Upstream GIT repository is more up to date, so there now is the package gtkam-git which builds well with up to date system.

The author of gtkam also responds to upstream issue reports.

Ahoj,

• At first, -Wno-implicit-function-declaration -Wno-error=incompatible-pointer-types needs to be added to $CFLAGS to work around errors like gtkam-preview.c:443:17: error: implicit declaration of function ‘gp_setting_set’; did you mean ‘g_settings_set’? [-Wimplicit-function-declaration] and gtkam-preview.c:564:61: error: passing argument 1 of ‘gtk_file_chooser_set_filename’ from incompatible pointer type [-Wincompatible-pointer-types] with up to date GCC (version 15.x):

Regards!

On an up-to-date system, makepkg fails with:

    Aborting...

I concluded to install: First: dependencies need to be installed. So simply : Try to install gtkam from aur to be sure that all dependencies are installed. When installer stops because of cheksum fail,stop installer and proceed as follow: download package : http://downloads.sourceforge.net/project/gphoto/gtkam/1.0/gtkam-1.0.tar.gz from terminal tar xzf gtkam-1.0.tar.gz then enter inside gtkam-1.0 directory cd ~/gtkam-1.0 ./configure make sudo make install done!

same problem than karhu. So i'm going to find the public GPG key on servers and find it. BUT this key is NOT trusted. Impossible to install/update gtkam.

Hi I get this message when I try to update from 0.2.0-2 to 1.0-1 : ==> Vérification des signatures des fichiers sources grâce à gpg... gtkam-1.0.tar.gz ... ÉCHEC (Clef publique inconnue 2209D6902F969C95) Now I changed the version without PKGBUILD and "the unknown public key", just manually.

Thanks valr - I had just made the symlink, but will rebuild

@perseus: you have to rebuild gtkam
