I think this may be related to compiling with a different C++ standard than the linked tensorflow library is built on. Would you be able to try the branch fix_tf_linking (commit 5c6bbf1)?

[yurivict]

Commit 5c6bbf1 still has the same problem.

[klarh]

Just to double check, is the fsph version 0.2.0 or 0.3.0, and if this was built with a checked out version of the repository, could you retry with a clean build directory? I found a similar error at one point where build artifacts with the old compilation flags were still left behind.

Failing the clean build and version issues, would you be able to attach or link to a build log in verbose mode?
