My personal "wishlist" consist of two things: 1. Generation of register.c must be completely reworked, cause most timesImust wait about 15-20 minutes when recompiling sources; 2. Make CMake default for win-platform building is really good idea.Are you using a platform native build of python or the Cygwin version? A platform native build should faster. When I've been doing intensive work on a single dissector I've commented out the bit of Makefile.nmake that generates register.c when it wasn't required.How I can detect this? I'm use windows-msi-installer from python.org. Version 2.7.2. Btw at compile time I get error in python scriptworks(anotherscript, not that script that generate register.c)Andriy, The output of nmake -f Makefile.nmake verify_tools will tell you which python you are using. If you've installed Windows Python 2.7 into the default directory it should be C:\Python27\python.exe.
[BSo I all the time use native python build :)
config.nmake has some settings for which python to use, but if you leave everything at the defaults it should pick up the Windows python installation.As the generation of register.c uses Python across all platforms replacing it would require another cross platform solution, and as my guess is that the generation is I/O bound moving to a compiled rather than an interpreted solution may not improve things.Anyway, to compile wireshark you need to install many other "more traditional" tools, like bash and perl. Hence there are pocible muchfasterreplacement for python :) But, i think, this is more holywat theme then practical.I would be very surprised to find Cygwin bash or perl faster than a native Python, or even a Cygwin Python. On my Win XP build VM, generating register.c using windows Python 2.7 takes 6 seconds.
Somewhy, when REbuild is in progress, generating register.c takes moooore time. But, when I do clean build(I mean after distclean), register.c generates in a few seconds.
