In order to run the tools in the Developer's Kit release after you install them, you must first set a few environment variables so your shell can find them.
PATH variable.
See section Setting PATH.
GCC_EXEC_PREFIX. Otherwise, the
compiler cannot find its resources. See section GCC paths.
INFOPATH so that info can find
the online documentation. See section Online documentation paths.
man programs recognize the environment variable
MANPATH as a search path for online manual pages. You must
either add your installation directory to your MANPATH
environment variable, or copy the online manual pages in your
distribution into a location where your man program can find
them. See section Online documentation paths.
