OpenCOBOL successfully builds with and then compiles using LLVM Clang. clang throughout the build process, including make check and tests/cobol85/make test. …
Well met,
It worked first try, well second, to correct some unit tests. OpenCOBOL builds with export CC=clang, then utilizes clang for later .cob compiles.
$ sudo yum install llvm clang clang-analyzer clang-devel
$ export CC=clang
$ ./configure

cobc is built with clang, and uses clang when compiling the .c generated from the .cob.
