Hi Pasha,
in your example below the problem is that $LD_LIBRARY_PATH gets only
expanded when searching for the library. So what happens is that the
system will look for $LD_LIBRARY_PATH/yourlib.so and of course
/user/cdf:/bla/bla:/xxx/yyy/yourlib.so
does not exist. To make it work as you expect TEnv should already do
the variable expansion. I've modified the TEnv class to do just
that for variables surrounded by $(). So in the new version you can
do:
Unix*.Root.DynamicPath: : .:~/rootlibs:$(LD_LIBRARY_PATH)
to get the expected behaviour.
Cheers, Fons.
