[Scons-users] UT application does not get built

[Bill Deegan]

There's really not enough info to help you.
Please provide simple test case which reproduces the problem..
Also where would you expect the test program binary to be produced in the
tree you've shared?
Or at least the contents of your SConstruct and SConscript.
