I see the same thing without the patch in the installed libstdc++.la. The real kicker is that the -L's for the build directory come before the -L's for the install directory. For an install, the order should be reveresed. > Also, there are an amazing number of -lm's and -lgcc_s's that are unnecessary. > > What I expect this to look like is simply: > > dependency_libs=' -lm -L/usr/pubsw/lib -lgcc_s' > > because, quite frankly, that is all that is necessary. It's my understanding that the extra -lm's and -lgcc_s's are added to handle cyclical dependencies. These may not be present on all systems. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=5291
