I recently installed Arch Linux and wanted to rebuild Valhalla and all its dependencies.

For prime-server, I got stuck following the documentation. When running make test:

  CXX      src/libprime_server_la-prime_server.lo
  CXX      src/libprime_server_la-netstring_protocol.lo
  CXX      src/libprime_server_la-http_util.lo
  CXX      src/libprime_server_la-http_protocol.lo
  CXX      src/prime_httpd-prime_httpd.o
  CXX      src/prime_proxyd-prime_proxyd.o
  CXX      src/prime_workerd-prime_workerd.o
  CXX      src/prime_echod-prime_echod.o
  CXX      src/prime_filed-prime_filed.o
  CXXLD    libprime_server.la
  CXXLD    prime_serverd
/usr/bin/ld: src/prime_serverd-prime_serverd.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
/usr/bin/ld: /usr/lib/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [Makefile:890: prime_serverd] Error 1
make: *** Waiting for unfinished jobs....

However, re-running ./configure LDFLAGS='-pthread' seemed to solve it. I guess this could be somewhere in the CMakeLists.txt. If not, happy to PR an updated documentation.

Oh, not yet used to Arch apparently.. Just found it in the AUR: https://aur.archlinux.org/packages/prime_server/.

Also, announced in Valhalla repo: valhalla/valhalla#1159.

At least Valhalla, maintained by the same account, doesn't seem to be at its latest.

we've seen this so many times on so many different compilers. at this point im wondering what is the right thing to do? it seems to me that some versions of GCC must be automatically linking pthread without it needing to be specified meanwhile other versions did not. or perhaps the project is freeloading off of other dependencies flags...

anyway because we ran into this a bunch of times already, we added it to configure.ac https://github.com/kevinkreiser/prime_server/blob/master/configure.ac#L37-L38

which should put the flag into your generated Makefile... We'd need to look at configures log and the generated Makefile to see what exactly is going on on your system.

I had the same issue on Fedora 31.
I still needed to add -lpthread to LIBS in Makefile to make it work

@noerw can you drop the output of config.log here?

sure

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by prime_server configure 0.6.5, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure

@noerw thanks! the output looks the same as mine with respect to DEPS_LIBS... so can you then do:

VERBOSE=1 make prime_serverd

and share that output?

hmm... i was expecting that this part:

  CXX      src/libprime_server_la-zmq_helpers.lo
  CXX      src/libprime_server_la-netstring_protocol.lo
  CXX      src/libprime_server_la-http_util.lo
  CXX      src/libprime_server_la-http_protocol.lo
  CXXLD    libprime_server.la
  CXXLD    prime_serverd

would actually show the compiler/linker command line and args... why isnt VERBOSE=1 working?

so this is your link line:

libtool: link: g++ -I/home/norwin/src/prime_server/prime_server -g -O2 -o .libs/prime_serverd src/prime_serverd-prime_serverd.o ./.libs/libprime_server.so -lczmq -lzmq -lcurl

and this is mine:

libtool: link: g++ -I/sandbox/prime_server/prime_server -g -O2 -o .libs/prime_serverd src/prime_serverd-prime_serverd.o ./.libs/libprime_server.so -lzmq -lczmq /usr/lib/x86_64-linux-gnu/libcurl.so -pthread

So it seems to me that this is a combination of this: https://lists.gnu.org/archive/html/libtool/2010-11/msg00032.html

And my misunderstanding about this: https://stackoverflow.com/questions/17055279/autotools-for-pthreads-not-setting-correct-linker-flags

Which means that my libtool must automatically inject pthreads for me and I incorrectly rely on that. So it seems to me I need to actually use PTHREAD_CFLAGS instead of hoping someone elses platform will add it for them.
