In a @code{csh} shell, you have to use the @samp{setenv} command for setting each of the environment variables. +Currently CLN works only with the GNU @code{g++} compiler, and only in +optimizing mode. So you should specify at least @code{-O} in the CXXFLAGS, +or no CXXFLAGS at all. (If CXXFLAGS is not set, CLN will use @code{-O}.) + On Linux, @code{g++} needs 15 MB to compile the tests.
