Created attachment 919446 [details] config.log During my most recent world upgrade I encountered the following configure failure for hwloc ``` . . . **** NVIDIA GL configuration checking for gethostbyname... yes checking for connect... yes checking for remove... yes checking for shmat... yes checking for IceConnectionNumber in -lICE... yes checking for X11/Xlib.h... yes checking for XOpenDisplay in -lX11... yes checking for NVCtrl/NVCtrl.h... yes checking for XNVCTRLQueryTargetAttribute in -lXNVCtrl... no configure: WARNING: Specified --enable-gl switch, but could not configure: WARNING: find appropriate support configure: error: Cannot continue ```

Created attachment 919448 [details] emerge --info
I ran into this issue as well. Try doing a fresh emerge of x11-drivers/nvidia-drivers before attempting hwloc again. In case this is relevant for anyone: I had neither the wayland or X USE flags enabled on nvidia-drivers when I encountered this. I was in the process of adding the wayland USE flag globally.
I recently added lto to my global USE flags and it was the problem, are you using lto? Disabling it for this package solved same situation. https://wiki.gentoo.org/wiki/LTO#Disable_LTO_per_Package
