SunOS 4 Binary Compatibility

Two major changes from the SunOS 4 environment hold true for SunOS 5.9 releases. The binary compatibility package enables dynamically linked socket applications that are based on SunOS 4to run on SunOS 5.9.

• You must explicitly specify the socket library (-lsocket or libsocket) on the compilation line.

• You might also need to link with libnsl by using -lsocket -lnsl, not -lnsl -lsocket.

• You must recompile all SunOS™ 4 socket-based applications with the socket library to run in a SunOS 5.9 environment.
