Under some circumstances, LibraryManager misbehaves and cannot find libraries.
We have started to see (initially in ROOT 6 upgrade work) that GCC is misinterpreting the regex used to find plugin libraries. This should be fixed, and tests put in place to prevent recurrence.
#3 Updated by Christopher Green almost 5 years ago
It is now understood why released versions of art do not exhibit the observed problem: there,
cpp0x/regex, which currently believes that GCC does not implement C++11 regex sufficiently, and therefore uses
boost::regex instead. The ROOT 6 upgrade has dropped
cpp0x, and therefore uses
std::regex from GCC, which triggers the problem.
