Re: [Boost-build] broken toolchain gcc + HP/UX-PA RISC -> ticket 1228with patches

From: Boris Gubenko (Boris.Gubenko_at_[hidden])

I use modified gcc.jam for testing Boost on HP-UX/ia64 with gcc 4.2.1. The 
results
are available on the web, see column: "HP-UX_ia64_gcc". While some tests fail, 
no
failure can be attributed to a problem in gcc.jam. This jamfile also seems to 
work on
PA-RISC: I did some limited testing -- setup phase of regression.py -- and all 
the programs
that are supposed to be built at this stage have been successfully built. I 
don't have the
resources to do full testing on PA-RISC. On both platforms, my user-config.jam 
has just:
'using gcc ;'

Attached patch shows what I've done. Like patch in ticket #1228, it implements 
the
suggestion in http://article.gmane.org/gmane.comp.lib.boost.build/15598 Unlike 
patch
in ticket #1228, it makes sure that '-static' option and soname is not used on 
HP-UX.
The latter eliminates "ld: (Warning) Can't hide symbol ..." warnings mentioned 
in:
http://lists.boost.org/Archives/boost/2007/09/127035.php There are other 
differences.

Should I add the patch below to the ticket #1228? Should I commit it and, then, 
if testing
on PA-RISC reveals some problem we can modify gcc.jam accordingly? From tests 
results
on HP-UX/ia64, this patch works just fine on this platform, so, if any change is 
needed, most
likely it will be to address some problem specific to PA-RISC.

When replying to this mail, please, cc me on the reply: boris.gubenko_at_[hidden]
I know for sure that I don't get all messages from boost-build list.

Thanks,
  Boris
