Did some testing. Results:
- A (hopefully attached) patch for waf so the patch to Warzone isn't
needed anymore.
- Speed seems better than before.
- 0.9.1: 1:17
- current svn: 1:07
- make: 0:57
I guess the make build is faster because of different options to gcc,
though I tried to use the same. Or perhaps something else in the
wscript file. On my last test, waf and make were roughly the same
speed.
- Sometimes there's some kind of deadlock when using -j3 (I haven't
noticed it without yet, but I usually use -j3), the last file shown
is src/aiexperience.c. Then waf hangs and even ctrl-C doesn't end it,
I have to use ctrl-\ to kill waf. I guess I have to investigate that
further if it's not a know problem. (Using the current svn waf)
- The working of the waf script is a bit tricky: It carries the
wafadmin directory attached to it, and puts that into ~/.waf-x.y.z,
but only if this directory doesn't exist yet. So when modifying it
you have to delete ~/.waf-x.y.z first, else you get the old version
and thus the modifications are not used.
- Is there an easy way to use several build directories with different
compiler settings? With the autostuff I can do for example:
mkdir debug; cd debug
../configure --enable-debug
make
cd ..
mkdir release; cd release
../configure
make
mkdir cpp; cd cpp
../configure CC="g++ -fpermissive"
make
and I can build a debug version, a release version and test g++
compilation, all from the same source tree. Is that possible with
waf? It seems blddir is defined in wscript without a way to override
it.
