configure.ac

   2 dnl Process this file with autoconf to produce a configure script.
   3 dnl The ONLY thing this is used for is to configure for different
   4 dnl linux architectures and configurations, it is not used to make the
   5 dnl code more portable
   6
   7 dnl You MUST have an environment that has all the POSIX functions and
   8 dnl some of the more popular bsd/sysv ones (like select). You'll also
   9 dnl need a C++ compiler that is semi-standard conformant, exceptions are
  10 dnl not used but STL is.
  11
  12 dnl 'make -f Makefile startup' will generate the configure file from
  13 dnl configure.ac correctly and can be run at any time
