Hi Iavor, It appears that HCSmain.cc does not contain a main() routine. Also, I presume that Solaris Workshop C++ generated object files are NOT compatible with GCC's C++ object files. (I expect that their ABI's are different.) That may be an issue if you are trying to mix-n-match. Plus, I would not expect Solaris generated object files to work with Linux. Even if it is Solaris for Intel and Linux for Intel. HTH, --Eljay
