Created attachment 773702 [details] hwloc-2.7.1 build log Hwloc-2.7.1-r1 build fails with the following error message: error: libXNVCtrl.a(NVCtrl.o): requires dynamic R_X86_64_32 reloc which may overflow at runtime; recompile with -fPIC The complete build log is attached. libXNVCtrl is part of the nvidia-drivers package. I don't know what this means. Should nvidia-drivers be built with the "-fpic" compile option? The complete build log is attached.

Hm, I have a potential suspicion of what might have happened, but the only way I see it may be possible is if you forced USE=-pie on gcc through /etc/portage/profile (haven't tried). Is it the case? Albeit there seem to be a lot of other custom things here which could have an impact.
NVIDIA uses -fPIC about everywhere relevant /except/ NVCtrl.o, it looks it meant to use it given the Makefile does += -fPIC, but that Makefile doesn't get used given the library is built by a higher level Makefile. `XNVCTRL_CFLAGS=-fPIC emerge -1 nvidia-drivers` would force it on which I could add to the ebuild. But as I mentioned, gcc defaults to enabling it unless you did USE=-pie on gcc -- just want to confirm if it's really because of that.

Well, I tried it and gcc[-pie] did allow me to reproduce. Do wonder why it's an issue /now/ given this -fPIC been always missing, but haven't looked at how hwloc builds. Don't see a problem with adding it to ensure it's used even with -pie anyhow.

Legacy 0/390 branch is not affected.
