### 2.4 Additional instructions for cross platforms

The `RANLIB` environment variable must be set to the path of the cross `ranlib` prior to running `configure` with the appropriate `--target` option.

For example, for VxWorks 5 execute:

           $ export RANLIB=ranlibppc
           $ ./configure --target=powerpc-wrs-vxworks [some options]
           $ make
           $ make install

Only one PolyORB installation (native or cross) is currently possible with a given `--prefix`. If both a native and a cross installation are needed on the same machine, distinct prefixes must be used.

Use `./configure --help` for a full list of available configuration switches.
