Problems with ssh and doxygen in makepkg

lardon · 2008-07-15 14:59:37

Hi,

When building a package with makepkg, if the build process uses either ssh (for cvs access) or doxygen, the build fails because these programs try to create config files in /root . Apparently, the problem comes from fakeroot : doxygen thinks he is running as root and tries to create the config files in /root. Has anyone had this problem before? Any solutions?

Thanks a lot!

try

export HOME=$startdir/src/.root

at the top of build()

Consider the following dummy pkg:

pkgname=dummy
pkgver=0.1.1
pkgrel=1
pkgdesc="A dummy package"
arch=('i686' 'x86_64')
url="http://shit.com"
license=('BSD')
depends=()

source=()
md5sums=()

build() {
    echo "$(whoami) ${USER}"
    echo "${HOME}"
    echo "${UID} $(grep root /etc/passwd)"
}

It produce the following output when running makepkg:

As you can see user environnement variables are still in the scope. So redefining variables is useless when programs get home directory path from libc.
fakeroot change you uid to match the root one and hook the standard library. Using strace you can see this inconscistency:

$HOME links to the user home
libc links to the root home

fakeroot must have a way of changing home directory for the fake root because this problem is recurrent when using program that need to write/read config from home directory.
i didn't manage to find this options...

Anybody has an idea to do that?

Tardo's solution doesn't work, any ideas? el cerdo's post describes my problem more precisely.

Thank you for yor dummy package. It is very interesting.

Sorry, but I do not agree. I cannot imagine a situation in which a package should alter or even read a user's directory, even if the user is root.

lardon, what is wrong with tardo's solution? Does it help to create that directory?
