how to build

[johnv02139]

• Antlr needs to be installed in /usr/share/java/antlr4-runtime.jar; this should be configurable somehow
  • one potential place for the Antlr jar to go is in <repo>/lib, but unfortunately lib is an actual source code directory; it would be nice to move the existing lib to another name and free it up to be used as a git-ignorable directory
• make install wants to write into /opt/sanka, which requires root permission; again, should be configurable
• can't figure out how to compile the generated C
  • added -I /opt/sanka/include for library dependencies
  • added -I../.. since I was in the directory with the C and H files
  • added -L /opt/sanka/lib -lsankaruntime This seemed to find all the dependencies. But it still didn't find main()

gcc -I /opt/sanka/include -I../.. WordMap.c -L /opt/sanka/lib -lsankaruntime

Undefined symbols for architecture x86_64:
  "_main", referenced from:
     implicit entry/start for main executable
     (maybe you meant: _WordMap__main)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Then again, I may never have compiled a C program on this computer...

The Makefile in example now shows how to simply compile a Sanka program to an executable.
