Hello,

when I build my application under Ubuntu (BLITZ + Shared libs)theIDE automatically use libstdc++6 although I've also libstdc++5. Some users using Suse and libstdc++5 report to be not able to run the program. They suggested me to link against the old libstdc++5 to increase the portability. How to do it? (Please consider that Blitz + All static option doesn't work and the only build method that works is only BLITZ + Shared libs).

Thank you,
Luigi

Another solution is maybe to link statically the libstdc++6. But how to tell to theIDE to perform this task? Any idea?

maybe try to have a look at "Package organizer" -> "Core" package -> Solaris - Link options.
What if to make something similar for you project?
Personally, I would experiment by trying to prevent linking the "bad" library (or e.g move to another dir) for any other packages involved and/or add Link option for your package.
But this is just an idea and I have little Linux experience...

Recently I got the answer to the problem of statically link libstdc++6 to my app:

Menu Package Organiser:
add the following link option to your package (right click):
-static-libgcc

Menu Setup/Build Method, in LIB section add (right click):
/usr/lib
/usr/lib/gcc/i486-linux-gnu/4.0.2

The last two rows are those in which reside the libs to link.

I believe that the only safe way how to link different stdlibc++ is to use appropriate GCC version.... (that is why there is "compiler name" in BM setup).

AFAIK, stdlibc++ is bound to that.
