Because I'm not familiar with boost.build and boost.jam I don't know the
correct description - sorry.
I see only some files which seams to contain data which controls the
build process.

site-config.jam and gcc.jam

I need boost libraries on HP/UX 11.11 which is PA-RISC (this is HPs own
processor).
This platform has HPs aCC compiler. HP has decided to promote Itanium
instead of PA-RISC processor on HP/UX Systems.
So HP does not provide aCC version 6.x on PA-RISC. The only version you
get is 3.x which is not able to compile boost libraries!
Thatswhy I'm forced to use gcc which is available on the traget platform
(including support for threading).

Neither - I need gcc but linker failed because wrong linker options
passed to it.

No! I want to use gcc with the correct linker options. Currently
boost.build passes gnu linker options to HP/UX linker. This does not
work.

No - aCC is left out of this scope beause it will not compile on this
platform (because the newest version available for HP/UX 11.11 is
obsolete C++).

Yes this works - but I do want shared libraries be builds per default as
it is done on LINUX.
If I type on LINUX 'bjam --toolset=gcc' the shared libraries are build.
If I type the same on HP/UX (with be corrections for the linker) the
shared libraries are not build. Why?

I was able to compile boost-1.33.1 on HP/UX 11.11 with gcc with no
problems.
Boost-1.34 (which I believe) comes with boost.build v2 make troubles as
I described in my previous emails.

Not user-config.jam it should be available for all users.

No - I want gcc on HP/UX PA-RISC!
