I have noticed somethig similar. Building a static lib works, but as soon as you try to link that static lib to another binary, you get duplicate symbols errors.

Edit: Someone opened an issue for the problem I actually have: https://bitbucket.org/multicoreware/x265_git/issues/622

[BtbN]

This is an issue in how the new temporalfilter header tries to use the private namespace:

https://bitbucket.org/multicoreware/x265_git/src/8584bc7bd99262b8bd926476c866840fe0d9428a/source/common/temporalfilter.h#lines-36

Just putting “using” into a header obviously does not work, since all the functions will not automatically be put into the namespace.
The header needs to use the namespace like every other header does, for example:

https://bitbucket.org/multicoreware/x265_git/src/8584bc7bd99262b8bd926476c866840fe0d9428a/source/common/threadpool.h#lines-30
