can't build?

[drillsar]

Any recommendations?

Using Gentoo Linux 5.10.27; GCC 10.3.0

/usr/lib/gcc/x86_64-pc-linux-gnu/10.3.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/src/mod_pagespeed/psol/lib/Release/linux/x64/pagespeed_automatic.a(107.signals.o.o): in function pagespeed_ol_apr_signal_description_get': signals.c:(.text.apr_signal_description_get+0xe): undefined reference to sys_siglist'
collect2: error: ld returned 1 exit status

As already outlined in bug #1717 ,
it's impossible to build on any recent OS if GLIBC >= 2.32
OS and GCC versions don't really matter.

As outlined among the major features of GLIBC 2.32:

• The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
  are no longer available to newly linked binaries, and their declarations
  have been removed from <string.h>. They are exported solely as
  compatibility symbols to support old binaries. All programs should use
  strsignal instead.

As already outlined in bug #1717 ,
the building phase works just fine even on GCC >= 10 if GLIBC < 2.32 (that's the case of Fedora 32 as outlined by the former bug reporter; only Fedora 33 switched to GLIBC >= 2.32)

PSOL needs to be fixed in order to be compliant with GLIBC >= 2.32; until then, it's going to be impossible to build pagespeed on any OS shipping a GLIBC released in the last 11 months.

I succeeded managing it in an ugly way

Part of my deploy script:

git submodule update --init --recursive --jobs=16 --force
...
sed -i -r 's/sys_siglist\[signum\]/strsignal(signum)/g' third_party/apr/src/threadproc/unix/signals.c
python build/gyp_chromium --depth=. 

The problem for good solution is that I just can't build PSOL for ngx with mod_pagespeed later than commit #409bd76 (after this one the bazel-build was implemented)
apache/incubator-pagespeed-mod#2069

Thanks @acachy. I put sed in my deployment script and I managed to compile the latest-stable branch on Ubuntu Hirsute (21.04)

Cannot build on latest debian stable (11 bulseye) and unless this is fixed it won't build on the next Ubuntu LTS either

This

sed -i -r 's/sys_siglist[signum]/strsignal(signum)/g' third_party/apr/src/threadproc/unix/signals.c

does the trick on at least ubuntu 21.04 (rolling) and 21.10 (devel)
