I've talked to tridge on Monday and he showed me waf. I've played a bit with
it and I think it is a nice tool. I think you can do the same things with waf
as with CMake. Here are my objections:
I've downloaded the latest version of waf and tried to compile the stuff
Tridge migrated. It crashed so I had to use a version Tridge fixed. This
didn't give a good impression of waf on me.
I've checked what compiler they support (gcc, suncc, msvc) and plattforms
(didn't find a list).
I haven't found a test infrastructure in waf I didn't find information how
they insure that a compiler and a platform is really supported.
CMake has a big test infrastructure and they ensure through nightly builds
that cmake works with different compilers on different platforms . I count
8 different platforms and 7 different compilers. This means
add_library(mylib SHARED mylib.c) will create a shared library on every
platform with different compilers.
As Samba runs on exotic platforms, they need to be supported. Currently only
Tru64 is missing in the CMake QA and Bill offered here to support Tru64 in the
future if we provide a machine with nightly builds. Earlier Björn said that is
not a problem as the machine is from SerNet and he would be happy to help.
If I look at waf then I think Samba will end up creating sambawaf maintaining
a build tool and supporting all those platforms and compilers.
Jelmer asked for cross-compilation support in CMake. I didn't find a note that
waf supports cross-compilation.
KDE is currently working on cross-compilation support. Especially for mobile
plattforms like Maemo, MeeGo and Symbian. Alexander Neudorf the KDE build
system maintainer is a CMake developer too. He currently works on supporting
new embedded compilers . So if you use CMake you will get this support for
free in the future.
