Hi, Vaclav,
pointing the absolute path to CXX solved the problem.
I have tested the calculation speed and compared it with GCC builds.
There is a small table, showing the relative calculation speed.
GCC, optimized........................... 1.0
LLVM, optimized........................ 0.91
So. GCC makes better binaries for the moment.
But I added also -O3 into CXXFlags in both cases, and there is what I
got:
GCC, optimized........................... 1.32
LLVM, optimized........................ 1.21
Anyway, GCC wins.
Vaclav, could you not have a look at "optimize" option in SConstruct?
It seems, there is a bug, it does not optimize a code, although "scons
-h" shows optimize=True.
Thanks

Why scons says, that it can't find clang++?
Sorry, Anton, I have no idea what happens on your computer. You might
need to set PATH in scons (don't know how, see man scons perhaps) or you
can say CXX="/some/directory/bin/clang++".
HTH, v
