Project Proposal: Build Infrastructure Changes

[Erik Trimble]

Cmake sounds very promising.

I would certainly think it merits a discussion of usefulness.

The major barrier I'd say is that it would require us to do a forklift
replacement of the existing gmake Makefile build system. That is, it is
unlikely that an incremental replacement of the gmake system could
happen. However, I would love to be proved wrong. A proof-of-concept by
someone on one of the major subsystems would likely be a first step
here.



Just to remind everyone, we currently would need something that can
provide a reasonable build system to work on the following OS and
compiler combinations:

Linux 2.4 & 2.6 (both 32- and 64-bit) with GCC 3.2 and later
Windows 2000 & Windows 2003 x64 with Visual Studio 2003
Windows XP & Windows 2003 with Visual Studio 2010
Solaris 8 with SunStudio 11
Solaris 10 (32- and 64-bit, SPARC and x64) with SunStudio 11 and 12

Plus, be adaptable to other platforms, such as MacOS 10.5 with its
compiler (gcc 3.??), Linux on PPC & ARM, AIX on POWER, HPUX on PA-RISC
or Itanium, Windows 2008 or Win7 with VisualStudio, etc.
