The problem is in configure: checking for the ld -shared flag... no The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/dev/ulm.git/commit/?id=3f79558a92d59bc8e691c04ea001eaaa94148a1d commit 3f79558a92d59bc8e691c04ea001eaaa94148a1d Author: Ulrich Müller <ulm@gentoo.org> AuthorDate: 2020-07-10 13:38:28 +0000 Commit: Ulrich Müller <ulm@gentoo.org> CommitDate: 2020-07-10 13:38:28 +0000 pam_skey: Fix configure test for ld -shared.

These are allowed in gcc: https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html Apparently clang has a problem with that construct. (Presumably it needs an extra option to enable support, but it looked simpler to remove the nesting instead.) |
