Hi, I uploaded the required information.
Hello, I followed the procedure available in https://github.com/arvidn/libtorrent/blob/RC_2_0/docs/building.rst and the library was built correctly. The only difference is: I did not apply any boost patch. My boost library is 1.77. I will try to update it to 1.78 (accordingly to the ebuild patch version.
Please try with GCC 10 or 11.
(In reply to Sam James from comment #6) > Please try with GCC 10 or 11. (the log of it building outside of Portage would be helpful too)
Hi, Sorry by the delay. I was in a farm without internet connection for some days. I updated my gcc to version 11 and it almost did the job. I believe this is a gcc related issue. I will try to use clang to build it. I will let you know. Seeya.

Hello, Some updates: - gcc 11 also reports a build error - clang 13 builds it However, if I try $ python -c "import libtorrent; print(libtorrent.version)" then I get an undefined symbol error: Traceback (most recent call last): <colombojrj> File "<string>", line 1, in <module> <colombojrj> ImportError: /usr/lib/python3.9/site-packages/libtorrent.cpython-39-aarch64-linux-gnu.so: undefined symbol: ERR_lib_error_string However, Sam helped to solve this issue by: 1. disable gnutls 2. build it with clang 13 I will test it with deluge and then I will post the results here.
It worked with deluge! Now I have a low power torrent client!

Everyone else seems to build with OpenSSL anyway. (Had numerous reports of this on IRC and on the forums, as well as on Bugzilla).
