Good morning, I hope that I'm not duplicating anybody's effort here - if I am, please get in touch so we can coordinate said effort. Anyway, to the subject at hand. About a year ago I posted a few results of my subsequently aborted attempt of getting Boost to work with the SunStudio 8/5.5 SUN compiler. Just about the only library I managed to get to work was the smart_ptr library. This still stands - I'm getting the impression that that particular compiler ran into even more hiccups with later versions of Boost. I've finally managed to get myself a decent spec SUN workstation and thanks to SUN now providing SunStudio 11 for the cost of a download, the latest compiler as well. Just got the whole shebang installed and attempted to compile boost without any configuration apart from adding the compiler to my path. The result looks pretty good so far - there are still a couple of compilation issues (most seem to be centred around type_traits/is_enum.hpp) and several link failures. I'll be looking into these hopefully over the next couple of weeks. So far, the overall results look a lot better compared to Studio 8 - after a build of the 'state' target with the basic sunpro tool set and absolutely no changes to the existing 1.33.1 configuration, bjam reports the following: ...failed updating 360 targets... ...skipped 192 targets... ...updated 877 targets... IME that's a massive improvement over results I got previously. Once I got to look into the problems above I should be able to set up a regular regression test and provide the results but I'm probably getting a tad ahead of myself... Regards, Timo
