Bug discovered during installation 32bit packages on 64bit system

[phracek]

I would like to install 32bit packages on my 64bit system but installation failed.
This issues was discovered from official DevAssistant package (not from GitHub).

Command line was:
da crt android -n myandroid

Android assistant is available here:

I can't reproduce this. Can you please specify what output yum install glibc.i686 gives you? This could theoretically be a problem in local repo setup or current state of your yum repo mirror.

rpm -q --whatprovides "glibc.i686"

I think that this command will always return "no package provides glibc.i686", because nothing really provides glibc.i686. And thus DevAssistant will try to install the package every time. glibc package provides, among others, glibc and either glibc(x86-64) or glibc(x86-32). So using glibc(x86-32) instead of glibc.i686 would be probably a bit better. Of course, this doesn't explain why YUM fails to install it for Petr.

[bkabrda]

Good point with the provides. I think we could check if the package ends with .<arch> and transform it to the (<arch>-<bits>) somehow, but I think we'd have to include a sort of "transformation table" (e.g. i686 => x86-32, ...) and maintain it... Or try to find out where this info is hidden in RPM

[phracek]

Yeah, good point. glibc(x86-32) solves the problem. I think that adding this information to documentation is enought.
