If I make PKGBUILD for instance for some GTK gui, should I put as dependencies also xfree and so on or it is ok to relay on the gtk dependencies?
I know that pacman check if gtk is installed and consequently you have alll gtk dependencies installed.
My question is mainly about the PKGUILD file format and what we have to write in it.
it never hurts to be thorough with you depends. that being said you can "keep it simple" and rely on other dependent packages to satisfy your dependencies. i always try and provide at least one depend though.
I am not your friend
