It should use ${EPREFIX}/usr/bin/ld, but the building system is misled. Any ideas? Reproducible: Always Steps to Reproduce: 1. Bootsrap a gentoo prefix on a host linux without the latest jsoncpp development package installed (for example debian sid's libjsoncpp-dev's version is not enough so this error won't be hidden) 2. Go into this prefix 3. emerge -v =sci-libs/tensorflow-2.2.0 Actual Results: Linking error thrown by non-gentoo_prefix linker Expected Results: No error occurs, successful installation

Thanks for your report. I have reproduced this bug.
It only happens when USE=cuda is set.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=03743bab4401db4277b5413d81f9a12650f7e63b commit 03743bab4401db4277b5413d81f9a12650f7e63b Author: Benda Xu <heroxbd@gentoo.org> AuthorDate: 2020-09-25 12:05:54 +0000 Commit: Benda Xu <heroxbd@gentoo.org> CommitDate: 2020-09-25 12:08:31 +0000 sci-libs/tensorflow{,-estimator}: add Python 3.8 and prefix support. tensorflow cuda build system hard codes /usr/bin/ld by default. This patch prefixifies it.
