Because there is no cross-compiler that can build Solaris code on the PC, the framework libraries that are linked into Solaris applications must be built on Solaris. In addition to the framework source files, you need a script that removes carriage returns from framework source files to be built on Solaris. These files are provided in the Solaris library's tar file, which is installed when you select the Solaris 2.x Libraries option during the IBM® Rational® Rhapsody® installation.
