This is a bug report for perl from hv@crypt.org,
generated with the help of perlbug 1.41 running under perl 5.31.1.
-----------------------------------------------------------------
[Please describe your issue here]
On this new computer with a freshly installed Ubuntu (bionic), I tried
to build blead with clang and threads support, which fell over at the
linking stage missing references such as pthread_get_specific() and
some maths functions.
Tracking back, I found during configure that it had:
Checking for optional libraries...
What libraries to use? [none]
I then found that I hadn't actually installed gcc on this machine, so
the /usr/bin/cc link was also pointing at clang.
After installing gcc (which updated the /usr/bin/cc link), retrying the
clang build successfully found:
What libraries to use? [-lpthread -lnsl -ldl -lm -lcrypt -lutil -lc]
.. to create the perl below.
Not sure if the fault here lies with me, perl or clang.
[Please do not change anything below this line]
