I was my own project. I have not looked at the testsuite.

Good question; I don't know.  I think the test is very old, but of course
VersionedSharedLibrary is new.  I'll check into it more.  (Had to spend
last night cleaning up the wiki.)

Strange. Wasn't this also happening before scons 2.3 ? Or had this test
been introdcued with scons 2.3 ?

Yes... however the fix for that bug will perhaps be a bit more involved. It
now causes an unnecessary rebuild even when LIBPATH changes but the actual
libs found did not change.  (That's the new test failure recently reported
here.)

if you're speaking of scons 2.3.0, I think it looks like an effect of
http://scons.tigris.org/issues/show_bug.cgi?id=2903
which will be fixed in the next release.

This was with my latest (with py3 support).  Would you expect that changing
rpath args would be noticed and cause a rebuild?

Is this with the latest default branch or released version?  What OS? If
you can send a working sample that would be helpful.

[Scons-dev] scons rpath vs signature

2013-10-02 Thread Neal Becker 
It looks to me that changing rpath arguments did not cause a rebuild.

I used:

env = Environment (ENV = {'PATH' : os.environ['PATH']}, CXXFLAGS=cxxflags, 
SHCXXFLAGS=shcxxflags, LIBPATH=[NDARRAYLIBPATH, BOOSTLIBPATH, IPPLIBPATH, 
MKLPATH, ACMLLIBPATH], CPPPATH=[NDARRAYINC, BOOSTINC, PYTHONINC, NUMPYINC, 
EIGENINC, IPPINC, MKLINC, ACMLINCLUDE],  RPATH=[NDARRAYLIBPATH, BOOSTLIBPATH, 
IPPLIBPATH, MKLPATH, ACMLLIBPATH])

Then when building shared libs, changing rpath did not seem to cause a rebuild.
