I'll try to supply Kylix and to make the regression tests working, but this could last some time (if there is no overwhelming demand ;-)
It would be very nice if you could have a look at it. From what I've heard Kylix BCB is very similar to BCB 6 for Windows. So, I don't see why it shouldn't be possible to get Boost working with it. Kylix does have a lot of bugs though, but most of the bad ones only appear when building shared libraries. Why do I want to use Kylix? Because it's very very fast as compared to gcc. When compiling the QT library, for example, Kylix is approximately six times faster than gcc (optimizations were turned off in both compilers).
I've got ublas working with both C++ Builder 6.1 and Kylix 3 now. There are a lot of fixes required, but I'll be submitting patches soon. Regards, John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm
