tbb 3.0 has been released

[josephsacco]

The current version of devel/tbb is 2.2, released 20090809. Version 3.0 is the current stable version released 20100406. Version 3.0 builds on a number of different architectures [See the build directory] including MAC ppc32 and ppc64.

I built version 3.0 on a dual 7448 G4 PPC [OS X 10.5.8] using Apple's gcc-4.2 and the default build system that comes with the tar ball. Version 3.0 will also build using Apple's gcc-4.0.1 All of the tests ran/passed, albeit slowly... :-)

FWIW... OpenCV-2.1.0 will build using TBB rather than openMP if available. [See the Change Log for OpenCV-2.1.0]

Portfile for building tbb-3.0

[josephsacco]

I have uploaded a revised Portfile that will successfully build tbb-3.0 on a G4 PowerMac. I suspect it will also work on other platforms, but that remains to be tested.

Some thoughts...

• The build uses whatever default Apple g++ and gcc it finds in /usr/bin. It might be worthwhile offer variants that allow tbb to be built with versions of the GNU compiler(s) installed in the macports tree.

• The examples were configured to build within the build tree. It takes some minor hacking to build the examples elsewhere. I am not sure it is worth adding enough scripting foo to the Portfile to fix this. If a user is interested in building these examples, learning to set the right include and library paths is a useful exercise left to the user... :-)

tbb-3.0 builds and runs on a MacBook Pro 2.8GHz Core Duo running OS X 10.6.4.

==> Time to update?

Joseph, please review earlier patch from #25208. I want to commit merged variant of tbb patch, cause'of maintainer timeout.

Joseph, please review earlier patch from #25208. I want to commit merged variant of tbb patch, cause'of maintainer timeout.

The Portfile generated by the patches in #25208 does not work on a PPC because of the lack of an appropriate build_arch. Modifying the if-statement logic to include PPCs works:

          ...
if {${build_arch} eq "i386"} {
    set arch_flag ia32
} elseif {${build_arch} eq "x86_64"} {
    set arch_flag intel64
} elseif {${build_arch} eq "ppc"} {
    set arch_flag ppc
} elseif {${build_arch} eq "ppc64"} {
    set arch_flag ppc64
}
               ...

I will review the other patches today and report back my findings.

Replying to drjesacco@…:

I have looked over the proposed patches and compared their effect to the effect of the Portfile patch I submitted three months ago. I do not see the benefit of the new patches nor do I see any harm provided the Portfile is altered to support PPCs. Your call...

FWIW... Some of the tests fail on both a 32 bit PPC and x86_64 platform irrespective of which patch set is used.

JFYI: +universal variant doesn't works - libs created only for x64
