Fixes for build on IBM pSeries for AIX and Linux

[wmichael]

This is a fix to allow building Boost on pSeries to 
work better. This fixes problem with the building of 
dynamic libraries and shared objects. It also adds a 
bunch of the latest option supported by the V8 
compiler. This unified diff patch has been tested on 
1.33.1 and CVS.

I have a few minor comments on the patch:

1) <optimization>speed is a feature that is meant to be common across all 
toolsets, so it should not be removed. It could translate to -O3 or -O4, 
perhaps.

2) <runtime-link>static is another feature that is meant to be common. Can 
it not be supported on XL C++?

Split patch in multiple files for easier review.

I have no problem with the 2nd Boost.Python patch. The first one essentially rips out a mechanism that we had to have on AIX to get things to work (because of its different linking model) and spent a great deal of time developing. I'm a little reluctant to apply that patch without having any explanation of why the mechanism is no longer needed. It's always possible they adjusted some flags in the toolset; if so I'm OK with it. However, if we're going to rip that thing out, we should also remove the aix_init_module.cpp source file from CVS and from Boost.Python's Jamfile.

Two further notes:

1. "It also adds a bunch of the latest option supported by the V8 compiler" probably implies we're breaking compatibility with earlier versions of this compiler.
2. This is an awfully large patchset to apply for a point release :)

[Thomas Witt]

Applied the following patches to RC_1_34_0:

tools-regression-compiler_status_cpp.patch (0.7 kB) - added by witt on 05/31/07 14:16:04.
libs-python-test-select_from_python_test_cpp.patch (0.9 kB) - added by witt on 05/31/07

[Thomas Witt]

Applied the following patches to RC_1_34_0:

boost-python-module_init_hpp.patch (1.8 kB) - added by witt on 05/31/07 14:11:32.

This makes aix_init_module.cpp obsolete. I did not remove it at this point as I don't want to mess with the build as such.

[Thomas Witt]

Update patch per request from guillaume.melquiond@…

[Thomas Witt]

Applied the following patches to RC_1_34_0:

boost-numeric-interval-detail-ppc_rounding_control_hpp.2.patch (0.7 kB) - added by witt on 06/07/07 14:43:02.

This was the last outstanding patch.

Removal of aix_init_module.cpp

[Dave Abrahams]

Patch enclosed to remove aix_init_module. The following files under libs/python should be cvs remove'd:

• src/aix_init_module.cpp
• example/Jamfile.v2
• example/Jamrules
• example/project.zip

I realize those last 3 are a separate issue technically, but they are each damaging in their own ways.

[Thomas Witt]

Applied patch and removed src/aix_init_module.cpp from RC_1_34_0. The example/... files are not in RC_1_34_0.

[ccambly@…]

Many of these patches have not been applied to trunk. I will re-open attaching patches for the trunk branch.

[ccambly@…]

Remove aix_init_module.cpp

[ccambly@…]

date time generator fix. nth_as_str is used before it is declared.

[ccambly@…]

Preprocessor iteration was fixed in V8 on IBM XL compiler

[ccambly@…]

Remove aix_init_module.cpp

[ccambly@…]

aix_init_module code is no longer required now that the libraries are built correctly. aix_init_module code has not worked since library tagging was added to Boost.Build.

[ccambly@…]

conflicting declarations from math.h

[ccambly@…]

Linker on LinuxPPC requires the definition of handle_execption_impl

[ccambly@…]

readdir_r is not thread safe by default on AIX this is why the wide_test fails.

[ccambly@…]

All the patches have now been attached that we are interested in.

[Steven Watanabe]

Someone with access to this compiler needs to review these patches and split them up into one ticket per library.

[viboes]

I propose to close this ticket. If the reporter want to make a ticket by component/library these could be taken in account by the library maintainers. Otherwise no body will be able to close this ticket, as no body can apply all the patches.

[Dave Abrahams]

Alternatively, you could make a ticket for each component addressed by this patch and simply point it at this ticket. That would probably be a minimal and fairly mechanical job.

[ccambly]

Over a period of the last few years we have been adding each of these fixes as separate tickets. Michael and I are ok with closing this particular ticket. I will open an remaining issues directly against the library.

[Jeremiah Willcock]

The BGL patches in here are obsolete (they are to files that no longer exist).

[Marshall Clow]

Over a period of the last few years we have been adding each of these fixes as separate tickets. Michael and I are ok with closing this particular ticket. I will open an remaining issues directly against the library.

Ok, then - I'm closing it.
