Created attachment 560936 [details] Build log I tried building dev-cpp/eigen as part of building KDEnlive from portage. This failed (log attached) with the following being the key part of the message: * Only gcc version(s) 4.7 4.8 4.9 5.3 5.4 6.3 6.4 7.2 7.3 are supported, * of which none is installed However, dev-cpp/eigen didn't pull down the right GCC version in the process of building (I have GCC 8 and 7.4, the latter also being pulled down by the KDEnlive build).

Ebuilds have no business with pulling in specific GCC versions, however I'm curious why this is coming up only now in what seems like a very stupid build system move; after GCC-8 being in ~arch for so long already (and I'm sure I've built eigen meanwhile).
[31;01m*[0m environment, line 3132: Called cuda_src_prepare [31;01m*[0m environment, line 1294: Called cuda_sanitize [31;01m*[0m environment, line 1286: Called cuda_gccdir '-f' ^ this is coming from CUDA. There is nothing that KDE or dev-cpp/eigen can do about it, you are responsible to set a compatible GCC version to satisfy proprietary needs.
