Can't install tensorflow 2.1.0 with 1.9.3_pre20200412. bazel complains about missing autolink.h An ugly workaround: echo '#include "config.h"' > /usr/include/jsoncpp/json/autolink.h
Created attachment 636778 [details, diff] patch resolving tensorlfow 2.1 installation issue In order to successfully install tensorflow I had to had these to package.mask 2 │ >=net-libs/grpc-1.28.1 3 │ >=dev-python/grpc-1.28.0 4 │ >=dev-python/grpcio-tools-1.28.1 And appply the attach patch
I had this problem also. Looks like jsoncpp is the culprit, here. My system wants >=jsoncpp-1.9.2, but the only versions in Portage are 1.9.1, and 1.9.3_pre20200412 (which seems broken) I resolved the issue by grabbing a copy of jsoncpp-1.9.2-r2.ebuild and dropping it into my local overlay. With that version installed, Tensorflow builds without issue. I found the ebuild for 1.9.2 here: https://gitlab.com/liguros/core-kit/-/blob/3938cb4eb8810a50be217710079f0446df702307/dev-libs/jsoncpp/jsoncpp-1.9.2-r2.ebuild but that was just the first hit on Google.
This issue appears to persist in tensorflow 2.2.0_rc2. Reverting to: net-libs/grpc-1.26.0-r1 dev-python/grpcio-tools-1.26.0 dev-libs/jsoncpp-1.9.2-r2 (custom ebuild as mentioned by Simon Detheridge) seems to have fixed the problem. Furthermore, when compiling with CUDA (dev-util/nvidia-cuda-toolkit), GCC <= 8.3 is required, which no longer seems to be a system default (17.1 profile). This creates its own set of problems; switching between GCC's makes reasoning about linking errors difficult. I did not find the patch to be necessary in 2.2.0.
Could be related to bug 719274
This is fixed in TF-2.2 and 2.3 :)
