Thanks for the patch. I just applied it here locally and it seems to work and
now a libgcc.so is build instead of libgcc_s.so
However, I am still having issues when building some software where it
complains about missing symbols (e.g. _Unwind_SjLj_Resume) which point out to
be symbols of the exception handling. After some investigation I found out
that I can fix that by explicitly specifying "-shared" or "-static" on the
link command line. Just with "-use-dynld" doesn't seem to be enough as
otherwise the new libgcc_eh.a is not added in the link line.
So right now I am a bit confused. Shouldn't be the default "-static"? Why do I
have to explicitly add either -static or -shared to get the link working when
compiling C++ projects. And what is this "-use-dynld" all about? I thought
that the commandline option I need to specify when linking shared. So why do
I have to use "-shared"?
Anyone has any idea and can explain the current confusion with -shared,
-static and -use-dynld?
cheers,
jens
