Hi, yes, this is the right place to report problems and to ask questions about midas.

As for your trouble, I have the same macos 10.13.6, so we should be able to figure out what goes wrong.

Unfortunately, the posted instructions (to run cmake directly) hide all the information needed to debug build problems.

Instead of "cd build; cmake ..", please run "make cmake" and post the output. Printed should be all the compiler
and linker commands executed by the build. You can examine the mhttpd linker command to see if somehow
the wrong openssl library is being used.

If you do not need built-in https support in mhttpd, you can run "make cmake NO_SSL=1".

K.O.
