I am trying to run a python script which includes a wrapper for a c++ code. The script runs on a linux machine without any issues. When I compile the c++ part with make, it throws me this error:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.4.sdk/usr/include/c++/v1/__filesystem/path.h:446:1: fatal error: declaration of anonymous class must be a definition class _LIBCPP_EXPORTED_FROM_ABI path { ^ 1 error generated.

Can anybody help me with fixing this? Thanks!

I tried re-installing both the Command Line Tools and XCode but nothing seems to work. I do not have any anaconda/brew/ports installed.

A good first step with problems like this is to try compiling a minimal C++ program, just to make sure that something isn’t borked with your tools setup. I have example of that here.

If that works you can start adding code snippets from your main source base to see if you can reproduce the problem.

Hi Eskimo,

I did that and everything works just fine. My macbook is brand new so I do not see how something can be broken with the tools setup. Any other suggestions?

Cheers, Alessia
