Mac make

In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/cstddef:37: ../version:1:1: error: expected unqualified-id 1.0.0

The reason for this problem is probably as follows:

1. the current directory (openabe/) is added to the library include path;
2. the openabe project has itself a 'VERSION' file;
3. the filename on macOS is case insensitive.

Thus, to address this problem, you can either rename the 'VERSION' file (in the openabe project) or just delete it.

---

If the project still cannot make successfully after applying the above solution, then you need to check whether there is a 'version' file under the '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/' directory. If not, you can try either of the following ways:

1. edit 'Makefile.common' and 'src/Makefile', and change 'gcc' to 'cc' or 'clang'
2. update 'gcc', and make sure its '--with-gxx-include-dir' configuration is like '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/c++'

Good luck~
