@petervdonovan Hi Peter. I really don't understand what's the problem and asking you for some insights.

The problem is the CI test runner can't find openssl headers, when making federate binaries.

The problem is this part.

/Users/runner/work/lingua-franca/lingua-franca/test/C/fed-gen/SimpleFederatedAuthenticated/src-gen/fed1/core/federated/federate.c:65:10: fatal error: 'openssl/rand.h' file not found

and I see it's happening when the make command occurs. But I don't understand why it's not working, because the CMake's OpenSSL linking has worked above. Also, the RTI build also works which also needs openssl headers.

I really don't know why it's not working. I have a bunch of tries on my commits, so you may check it out if the CI test takes too long.

I hope for your help!

It looks like you're doing basically the right things here, and I do not know off the top of my head what the issue is likely to be. However, here are some ideas:

• where you write if (osName.contains("mac")) { in CMakeLists.txt, make sure that it isn't returning darwin, or something like that, instead of mac. You can add debug prints to the CMakeLists.txt if you need to in order to check that the branch is being executed.
• You can also try to SSH into the GitHub Actions runner. This is surprisingly easy and is briefly mentioned here.

Wow. Never knew I could ssh into the runner. I'll try that! Thanks!

@lhstrh It's finally ready. Thanks to @petervdonovan telling me the ssh trick!
