Launching gpg-agent 2.2.7 as daemon produces the following error and then quits:
gpg-agent: Fatal: error allocating thread attributes: Function is not available
Running on HP-UX 11.31.
I am able to run gpg-agent version 2.0.30 with nearly the same libraries successfully. The only difference is the use of pth in version 2.0.30 vs. npth 1.5 in version 2.2.7. The tests that came with the build of npth 1.5 ran successfully.
