PMON2000 is verified to build on Linux 2.6.x and *BSD using GCC 3.3.5 and Binutils 2.15. You will also need bison to build pmoncfg. To help setting up the GNU cross toolchain on Linux the attached script is provided.
Environment variables are used to control the behavior of PMON2000 and pass information between programs. Some variables affect console input and output, other controls the default settings for commands while some controls the boot process such as boot device and automatic startup.
