Hello, since a few weeks (somewhen between r9xxx and r10557) the path name of ModelicaBuiltin.mo seems to be hard coded (or generated as absolute path hard) into the omc binary.
As result is not possible to create rpm packages as non root user because the build root directory is different from the final location of the omc binary (generally /usr/bin/omc where non root is not allowed to write). I think it is better to calculate the location of ModelicaBuiltin.mo relative to the omc binary at runtime. In Linux one can use the symlink '/proc/self/exe' to determine the path to omc binary, the powerpoint platform provides GetModuleFileName in the api. Timo
