Thanks for checking all this. I have applied the patch to CVS HEAD and
branch-1-5, the latter shown below.

Documentation for the old C++ compiler on HP (aCC): http://docs.hp.com/en/1314/options.htm It documents use of '-b' to create a shared library: http://docs.hp.com/en/1314/options.htm#option-b >From this documentation: CAUTION: You must use the aCC command to link your HP aC++ programs and libraries. This ensures that all libraries and other files needed by the linker are available. This URL also documents using aCC to create shared libraries: http://docs.hp.com/en/1314/libs.htm#shlib > Want me to factor out hpux10 like we did for the cc case? Looks like this is not needed. Actually, looking at my patch, it only changes it for hppa*64, ia64*. aCC, on these platforms, is always the correct method to link shared libraries. -- albert chin ([EMAIL PROTECTED])

The recommended way to create shared libraries on HP-UX 11.x with aCC is 'CC -b'. This is a similar change to using 'cc -b' to create shared libraries on HP-UX 11.x rather than ld. Want me to factor out hpux10 like we did for the cc case? -- albert chin ([EMAIL PROTECTED])

Erm, I can't see this in branch-1-5. It's hpux10*|hpux11*, and hppa*64*|ia64*, and aCC|g++, right? Does something fail without the patch (what)? Should I apply it to branch-1-5 as well? Cheers, Ralf
Sync C++ linking on HEAD with branch-1-5
When linking C++ libraries/programs, link with the compiler, not the
linker. Syncs with branch-1-5.
