Thanks. I want to build like this because I can then use multiple build
directories with different options (debug/release/profile/stdlib-debug
etc.) In order to do so the build system must not write anything into the
source directory.

OK, I tried that and here comes the next error: It does not find qt if I
don't give the qt dir on the command line:
~/lyx-1.5/build-tree-scons$ scons -f ../development/scons/SConstruct
build_dir=.
scons: Reading SConscript files ...
Qt library directory is not found. Please specify it using qt_lib_path
Since pkg-config finds qt just fine I should not be forced to give any qt
commandline option (and even if I would not have pkg-config it should just
work because qt is installed in /usr/include, /usr/lib and /usr/bin). Next
try:
~/lyx-1.5/build-tree-scons$ scons -f ../development/scons/SConstruct
build_dir=. qt_lib_path=/usr/lib
Now it finds QtCore and QtGui, but then wants a QtCore_debug and
QtGui_debug:
Processing files in src/frontends/qt4...

I don't know any Linux distro that has QtCore_debug and QtGui_debug
packages. Why does it search for these? If I want to debug qt I can load
the debug symbols from an extra file that comes with the qt debug package.
Apart from that building LyX in debug mode does not automatically mean
that I also want to debug qt. Commenting out line 348 in qt4.py seems to
fix this problem, at least it starts to compile.
BTW1 the error message above is misleading: QTDIR cannot be given on the
scons command line, it is qt_dir.
BTW2 I get bogus boost messages:
Checking for boost library signals, regex, filesystem, iostreams...
Warning: Can not find an appropriate boost library in /usr/lib.

This is double wrong. I do have the boost libraries installed in /usr/lib,
so they should be found. And it wants to build with the included boost, so
they should not be searched in the first place.

PS: I am deliberately not looking at any scons documentation. If scons
should replace the autotools one day it needs to be as simple to use as a
configure; make; make install; sequence.
