Problem description

I had a misconfigured compiler (Conda clang, macOS, missing sysroot configuration, the specifics here aren't too important) and Cantera's configuration step was failing, with the error message about std::isnan not being available, introduced in #1161. However, inspecting the config.log showed me other errors, mostly that the linker couldn't find a few standard libraries.

The problem is that the failure was not due to missing std::isnan, so I think the error message is too eager.

Steps to reproduce

I'm not sure what an easy way to reproduce this is... perhaps move one of the standard libraries out of the search path temporarily?

System information

• Cantera version: I'm building from a branch off main, but any commit after Prevent errors due to unsafe math optimizations #1161 was merged should do.
• OS: macOS, but I don't think it's important
