Linking a GCC-compiled library using Sun Workshop

Linking a GCC-compiled library using Sun Workshop

Post by Matt Hatch » Fri, 06 Sep 2002 00:02:55



I'm having problems linking an .a type static library archive using
Sun Workshop 5.0 under Solaris 2.6.

The archive was built with GCC (unfortunately I do not know which
version - is there a way to determine this from the archive?). If I
build an executable with CC using only the archive on its own then it
links fine, however if I include any other .c or .o files that
reference any of the functions contained within the archive then they
are not found and I receive symbol referencing errors.

My reason for using Sun Workshop is that I need also to link in some
C++ libraries compiled with WS5.0, and because of the name mangling
differences I can't use gcc to link them.

I am not able to recompile either of the libraries, so my simple
questions are: should this combination be possible? is there an
obscure link flag that I need to set? can someone suggest a
solution?!?!?!

Thanks in advance for your assistance,

Matt Hatcher.

Mixing objects generated with different
vendors' C++ compilers is almost impossible.
Even if you get this to link, you will probably see
unexpected runtime behaviour.

1. Using the OTL oracle library with Sun Workshop 5.0

Hi,

I'm a fairly new developer to Sun Workshop 5.0 (long time Windows developer,
sorry, just got smart <g>). I'm trying to use the OTL oracle library from
http://www.geocities.com/skuchin/otl/home.htm which looks really useful, but
it won't compile under Sun's Workshop 5.0 C++ compiler. I've emailed the
auther and he has tried to help me out, but says it works under the 6.0
compiler as that has a more complete STL implementation. Has anyone used
this libray and if so, what was your experience with it and did anyone get
it to compile under Workshop 5.0 C++?

Thanks,
Doug Farrell
