Help, I don't know how to solve this. I also tried the stable version with the same error.

[Lofesa]

Maybe is a library incompatibility. Signals comes from the stardad c libraries ans seems that is used by apr_memcached.
@oschaaf can you take a look on to this?

[oschaaf]

fedora/gcc10 just isn't a platform that we test building on. There probably aren't any fundamental blockers, but it may take some trial and error to get this to work.

[bymoye]

fedora / gcc10并不是我们测试构建的平台。可能没有任何基本的阻止程序，但是要使其正常工作可能需要反复试验。

But there is no problem in fedora 32 gcc:10.2.1....

[Lofesa]

Maybe gcc version related?

[eilandert]

it's glibc related I believe, every distribution released since +/- 1 year won't be able to compile, see #1735. I can compile it on ubuntu focal but not later.

[Lofesa]

I don´t know if in Ubuntu can be set a dual gcc installation or downgrade the gcc.
I compile the module with gcc 9.3.1 on a centos 7 server and it build

[eilandert]

Personally, I have no problems to build on focal or whatever distribution, as I build in Docker. But I do think this a problem what should be solved in the long-term future. Unfortunately I have too little knowledge on the problem to help fix this :-(

Just ran into this issue on NixOS unstable.

this error means you are trying to use a psol library built on an older glibc.
(for example, the psol library is built on ubuntu focal or bionic, you are using ubuntu jammy).
On newer glibc they removed pthread_mutex_consistent_np and sys_siglist functions

I uploaded precompiled psol binaries here: http://www.tiredofit.nl/psol-jammy.tar.xz

[GwynethLlewelyn]

@eilandert you're absolutely correct! I read your comments on issue #1743 — it took me a while to fix the toolchain, but, eventually, with your precompiled binaries, I managed to succeed. I'm sure that others will, too.

On the other hand, to @bymoye and other maintainers/moderators of this package: it would be nice to fix the autoconf files, so that it properly checks for the glibc version used by PSOL, and recompile it — if needed — using a more recent version, with the patches provided under issue #1743...

[eilandert]

I cooked some build instructions in #1760
