I tried and before I got to testing the patch I ran into an issue building Emacs on macOS 10.15 (aka Catalina). When I run make I get the following error: xml.c:26:10: fatal error: 'libxml/tree.h' file not found #include ^~~~~~~~~~~~~~~ 1 error generated. make[1]: *** [xml.o] Error 1 make: *** [src] Error 2 /Applications/Xcode.app/Contents/Developer/usr/bin/make -C lib all make[1]: Nothing to be done for `all'. /Applications/Xcode.app/Contents/Developer/usr/bin/make -C lib-src all make[1]: Nothing to be done for `all'. /Applications/Xcode.app/Contents/Developer/usr/bin/make -C src VCSWITNESS='$(srcdir)/../.git/logs/HEAD' all CC xml.o xml.c:26:10: fatal error: 'libxml/tree.h' file not found #include ^~~~~~~~~~~~~~~ 1 error generated. make[1]: *** [xml.o] Error 1 make: *** [src] Error 2 Mac OS X 10.14 has stopped placing the include libraries in their usual location, /usr/include, keeping them only inside the XCode directory. The work around was to run a pkg installer included in the XCode directory.[1] I can no longer find that file or anything similar in macOS 10.15. Any tips are appreciated. I will try to build and test the patch again this weekend. There was something in the article I referenced about linking the path where the libraries are to /usr/include but it wasn't recommended because it overrides the default behaviour expected by Mac OS and requires you to disable SIP (System Integrity Protection). I am open to trying anything.
