HTH.

The default build on windows builds both versioned *and* unversioned libs (at least for 1.34.0 - can't remember back to 1.33.1 building). If specifying "--layout=versioned" on the bjam command line results in *only* versioned libs then the bjam 'default' is actually something else, no?

The libs versioned creates are internally versioned. It only creates *links/copies* with the unversioned names. For example, in Windows, if you link to the unversioned DLL link library (boost_*.lib), the resulting binary will depend on the versioned DLLs. Same applies on the Unix side. The libs produced by the system layout, are built internally without the version info (if I remember correctly). -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

Yes; it's exactly this copy that I'd like to suppress. Is there a way to do that? (Brutal modifications to the Boost build infrastructure are welcome suggestions; I just need some direction here.)

Open up boost-root/Jamfile.v2 and comment out, or delete, these lines: generate stage-unversioned : stage-proper : <generating-rule>@make-unversioned-links ; explicit stage-unversioned ; generate install-unversioned : install-proper : <generating-rule>@make-unversioned-links ; explicit install-unversioned ;

I don't think so. Looking at Solaris, anyway:

$ ls -shF lib/libboost_thread* 1.0K lib/libboost_thread-sw-mt-d-1_34.so@ 240K lib/libboost_thread-sw-mt-d-1_34.so.1.34.0* 240K lib/libboost_thread-sw-mt-d.so*

That's after building with "variant=debug link=shared threading=multi". The first listed there is a symlink; the latter two are not. I'm reasonably sure that if I linked against the last one in this listing, that dependency is exactly what I'd get.

That would be a mistaken expectation ;-) Note that those last two are exactly the same size. They aren't copies and rebuilt libs. They are hard-links to the same inode. As in it executes: ln libboost_thread-sw-mt-d-1_34.so.1.34.0 libboost_thread-sw-mt-d.so Hence the soname in the library is still the versioned in both. Which is what ELF, and others, will use to reference to link in the future to the library. Of course the soname only applies to platforms which have such support. So your statement may be true in some minority of platforms. Additionally, for Windows, the link library that matches the DLL refers to the versioned DLL, since it's just a copy of the versioned link library. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - grafikrobot/yahoo

I see all 3 postings, check your mailing list settings (there is an option that you don't receive your own postings). Cheers, Filip _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
