Using the command names common to the xlc and c89 utility

The c89 and xlc commands support the c89, cxx, cc, and c++ command names. Users can use the c89 or xlc versions of these commands.

The c89 utility is installed in the /bin directory. To use the c89 version of these commands, the /bin directory must precede the /usr/lpp/cbclib/xlc/bin directory in the PATH environment variable.

xlc is installed in the /usr/lpp/cbclib/xlc/bin directory. To use the xlc version of these commands, that directory must precede the /bin directory in the PATH environment variable.

If the /bin directory precedes the /usr/lpp/cbclib/xlc/bin directory, you can still use the xlc version of these commands. To do so, use one of xlc, xlC, xlc++ and related command names (such as those with the _x and _64 suffix) and the -F option.

Example: To invoke the xlc utility using the c89 command names, issue:

 xlc -F:c89
