To Compile and Link on Linux

g++ -DLINUX -D_REENTRANT -Iheader_path -o Producer \\
    -Lruntime_path -lmqcrt Producer.c

where header_path and runtime_path are the paths to the Message Queue header file and runtime shared library appropriate to your installation method, as listed in Table 1–1. For example, when using an installation from rpm packages, you would specify /opt/sun/mq/include as header_path and /opt/sun/mq/lib as runtime_path.
