RE: [boost] Re: changing aCC-Link-action
I have attached the updated acc-tools.jam file located in boost_1_31_0/tools/build/v1. I added the following option to the compile line: +z - to make the compiler generate PIC (position independent code) -- required for shared libraries. -w - suppresses warning messages And to the link line: -b - to tell the linker to generate a shared library instead of an executable. I'm assuming that aCC-Link-action is only used for generating shared library? Do you happen to know which thread functions where missing? -Jerry -----Original Message----- From: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] On Behalf Of David Abrahams Sent: Tuesday, May 11, 2004 1:50 PM To: boost@lists.boost.org Subject: [boost] Re: changing aCC-Link-action "DY, JERRY U (SBCSI)" <jd2419@sbc.com> writes:
I would like to add options to the compile and link line used for building the threads library. I have added as follows but not sure if it's the proper place for it. With these changes, I'm able to cleanly compile and build the threads shared lib using aC++ 3.55 compiler. Credit to the HP aC++ team for their help on hpux.hpp changes.

Hi Jerry, Thanks for the info. I don't think we want to define BOOST_HAS_PTHREADS unconditionally, because IIRC at least some versions of HPUX's headers don't contain one or two of the functions used by Boost.Threads It's more effective to post a patch as an attachment, so there's no ambiguity about how mailers have mangled it, and so it can be automatically applied. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
I have attached the updated acc-tools.jam file located in boost_1_31_0/tools/build/v1.
+z - to make the compiler generate PIC (position independent code) -- required for shared libraries.
That should be conditional on us actually building a shared library - we build static ones as well, not to mention executables.
-w - suppresses warning messages
What all of them?
And to the link line:
-b - to tell the linker to generate a shared library instead of an executable. I'm assuming that aCC-Link-action is only used for generating shared library?
Again we need to make this conditional on us actually building a shared lib, Rene, Dave, how does one do that? Thanks, for persisting with this, John.

If it is all of them it should be: flags acc CFLAGS <warnings>off : -w ;
And to the link line:
-b - to tell the linker to generate a shared library instead of an executable. I'm assuming that aCC-Link-action is only used for generating shared library?
No it's used to link everything except library archives.

Oops :-) That should be "target-type", singular not plural. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq

It works ;-) But the reason I posted it that way is because it's easier to understand for non-jam knowing people than trying to describe how to change the link action. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq

Ah I see... Yes and no ;-) I already, previously, corrected myself on that one. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq
