Building with rpmbuild under Ubuntu

I need to build yum with a patch under Ubuntu 10.4 (reason being that i need a yum with chroot support for my vserver instance)

Since yum src for ubuntu where not avaliable (3rd party repos) i downloaded the source off the offici开发者_JS百科al repos and the patch off the linux-vserver.

However, when i try to build it with

rpmbuild -ba yum.spec 

It fails with

error: Failed build dependencies:
    python is needed by yum-3.2.22-0.src
    gettext is needed by yum-3.2.22-0.src
    intltool is needed by yum-3.2.22-0.src

Now i have all of these installed and i have no idea how to resolve this since i don't go rebuilding my stuff everyday.

Regards, V.

The problem is that rpmbuild is trying to resolve the dependencies using RPM's own database of installed packages - which is not the same thing as apt-get's database. apt-get knows those things are installed, but rpm doesn't.

Since you're sure you have these things installed, I'd suggest editing yum.spec and removing them from the BuildRequires line.

The solution is to enter the right deb-src repos to your yum list, download the source with apt-get source yum and apply the patch. Finally build the package with dpkg-buildpackage.
