Hi,
I have two packages (one linked to the other) to build on different architectures and platforms. In order to build the code for a specific platform I need a specific version of gcc (v.6.0) but when the build kicks off for OpenSuse 42.2 I get the following error despite the fact that gcc6 is available on that distro.
unresolvable: conflict for provider of libgcc_s1 >= 6.1.1+r238085-1.12 needed by gcc6 (provider libgcc_s1-gcc6 is conflicted by installed libgcc_s1)
I'd like to keep the two .spec files as aligned as possible (hence keeping the dependency in both of them) to avoid bugs introduced in one version of the file vs the other.
The build is successful for the Factory repos.
Is there a way to fix this problem (i.e. force OBS to use/install a specific version of gcc) ? On an installed distro (42.2), this works fine by installing one version of gcc rather than the other...
Yes, but there is only a way via the prjconf:
Preinstall: !libgcc_s1 Preinstall: libgcc_s1-gcc6 Thanks for the hint; however, this I think is a project wide setting so all

yes, right, but the newer libgcc_s1 should be fully backward compatible. So IMHO the risk is really low.
A possible solution then would be to create a project containing only the packages which I need to and separate others...?
IMHO we should modify our official project configuration of openSUSE to use
the newer libgcc_s1 always. We can maybe do this in :Update project at least?
I was wondering the same; if we have gcc6 available for 42.2 why OBS is still (by default) building with the older compiler?
because it is still the default compile used in SLE and therefore all sources are only QA'd with the older one.
Couldn't we have the most recent one (available for a given distro) being the default compiler for OBS?
No, but IMHO the switch to the newer libgcc_s1 should be okay. That way a package just needs to BuildRequires: gcc >= 6.0 or alike to switch.
Ludwig?
