emere --info eigen
I think I know where this comes from: from cuda. https://bugs.gentoo.org/674570 Right, no need for a duplicate. *** This bug has been marked as a duplicate of bug 674570 *** I would keep this bug open until 674570 is resolved. This is convenient for people who fail to build eigen and are looking at related bugs for solution. And the relation to cuda is far from obvious. CUDA being horrible is technically not a bug. Every user of it must be aware of its toolchain limitations. I don't argue with that nvidia is evil, and I feel your emotion. But I would prefer gentoo to be friendly. Right now, eigen fails to install with a cryptic message, which turns out not to be eigen's fault, but is it absolutely not clear from the message. I think it is sensible to keep a bug open, so people who look into the issue don't have to spend time on it. This saves time for gentoo users. When the message is improved, or the problem goes away, the bug should be closed. Now this should be fixed by https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=80eaf4a2f289a4dc883265b58ae56d7519f97645 |
