RE: Help needed to build shared library with libtool

[David Aldrich]

Hi Peter

Thanks for your reply.
> -shared is not a libtool flag

Oh, that's weird! We've been using that option for building other shared 
libraries for a long time.

That doesn't work, but the result is different:

libtool --mode=link g++ -o libGUI.la <my obj files>  -rpath /usr/local/lib 
-rpath /usr/lib64 -L/usr/lib64 -pthread   -L/usr/lib64
