[Scons-users] scons-local-2.5.1 build and clean shows random failure

[Hua Yanghao]

I tried first with the SConscript variant_dir parameter but seems it
doesn't work:

+        lib, objs, objs_all = ENV.SConscript(true_scons_file,
variant_dir=output)

And the result is:
hua at grass:~/git/usw $ configs/linux64_full.py
Running : ./tools/scons config=linux64_full.py
scons: Reading SConscript files ...
output dir: output/linux64_full
output dir: output/linux64_full

scons: *** 'output/linux64_full' already has a source directory:
'arch/linux64_full'.
File "/home/hua/git/usw/site_scons/common.py", line 61, in BuildObjList
hua at grass:~/git/usw $

I found that if I want the the build to happen in the output/linux64_full folder
I have to call SConscript file from e.g.
output/linux64_full/src/SConscript instead of
the top level true SConscript file (src/SConscript).

Did I use it wrong?
