Hello,
In yout ltconfig script, there is the following comment concerning
building shared libs on solaris:
(this is taken at line 1335 of ltconfig, libtool version 1.3c 1.687,
2000/02/03)
# $CC -shared without GNU ld will not create a library from C++
# object files and a static libstdc++, better avoid it by now
This choice prevents me from compiling correctly with libtool on
solaris.
I have to build a c++ shared library that uses exception. Linking the
shared library with libtool prevents exceptions from working correctly.
In my experience, I do get correct results by manually using $(CC)
-shared, at least with gcc 2.95.2.
g++ calls collect2, which calls the linker. I only have the native
linker installed on my machine.
Here's a verbose transcript of what gcc 2.95.2 does when linking a
shared lib.
The setup is a c++ shared library that internally uses exceptions
(libtest.so),
with a c++ program using it (main).

So maybe this requirement isn't a requirement anymore?
Can anyone with the expertise clarify the situation, please?
Thanks!
