Hi,

Has gcc-c++ been removed as one of the automatically included dependencies at build time in OBS? A large number of packages in devel:languages:R:released are now failing to build due to g++ no longer being available, and we've changed nothing in the R-base-devel package Requires which they all rely on.

Can anyone shed some light on this?

It was never installed by default before. If it worked before some other package required it, you had it in prjconf or in BuildRequires.

But does not matter much, if your package needs it, it should BuildRequire it IMHO

We have BuildRequires: gcc-c++ in R-base.spec. Some traces: For example AlgDesign fails, that has Requires: R-base and BuildRequires: R-base-devel. R-base-devel requires R-core-devel R-core-devel requires R-base. I would expect gcc-g++ coming onto the field there? Nevertheless, nothing changed on our side, what makes the failed builds strange.

R-base-devel requires R-core-devel

R-core-devel requires R-base. I would expect gcc-g++ coming onto the field there?

BuildRequires are not transitive. gcc-c++ is required to build R-base, but not for installing it. So building AlgDesign requires R-base-devel, and thus R-core-devel and R-base, but not gcc-c++, install time requires *are* transitive.

That means gcc-c++ will be installed when *building* R-base. It says nothing about the dependencies of the packages it produces.

No, unless R-base *requires* gcc-c++.

BuildRequires is about build-time dependencies. Requires is about install-time dependencies. Build-time dependencies are not transitive.

Ok, that is like I did it from the beginning of times, erhh OBS, until at some time in the long forgotten past I obviously misunderstood a hint regarding some *Requires. Well. Thx for clarification. Will have to add a few Requires. It remains the question: Why did the build results change *now*? May be not so important, will have to find the proper place to add gcc-g++ anyway. Detlef
