after I upgrade my MacOS to version 11, the error is showing

I have tried different version of command line tool (12.1, 12.2, 12.3, 12.4), the error still exists

please help me to solve this issue, thanks!

I found the root cause

1. after upgrade command line tool, there's a include file named version (used to be __cxx_version and be included by lots of std lib)
2. compiler try to #include<version>, HOWEVER, there's a file named VERSION under the source code for waf to get essentia version

the way compiler try to find this version is case-insensitive, so the wrong VERSION is used.

---

here is my workaroud: (under the essentia source code)

1. rename VERSION to VERSION_waf
2. revise wscript

VERSION = open('VERSION_waf', 'r').read().strip('\n')

then the error log disappeared and successfully built

Thanks for reporting. It might only happen on case-insensitive filesystems, but even so, we should not have the -I compilation flag pointing to the source root directory where the VERISON is located (only src/* folders are included).

Update: I can reproduce that the compilation includes flags -I. and -I.. that lead to this issue.
