It sounds like you are trying to include a binary as a header file. Does your CPATH environment variable perhaps include an empty string (::), contain . or start or end with :? We've had many issues like that in the past.

TomasOberhuber commented 5 months ago

Yes, it helped. It has never happened to me before. I am sorry for that. Thanks a lot.

upsj commented 5 months ago

No worries, this is among the most obscure build bugs we had so far. That happens if you have an executable that is named the same as a standard library header. We could probably rename the test, but that would make things inconsistent, so we avoided it so far
