I have talked to multiple developers about this, yet none has assumed responsibility, so I'm not sure where to raise this: Building inside boost/tool/wave/build on trunk fails for me due to a link error, since wave wants to link to boost_thread, but doesn't link to -lpthread. (This is the default toolchain on my Fedora 8 box, i.e. GCC.) I'm not sure where the -lpthread needs to be added (I added it manually to the link command and it succeeded), or in fact, why wave links to boost_thread at all. It doesn't use threads underneath, or does it ? Another point I just touched on with Volodya on IRC is that all tools are built against the static boost libraries, presumably because Windows doesn't have the equivalent of -rpath. Could that be changed at least for non-Windows platforms that would allow it ? Thanks, Stefan PS: Thanks for changing the default to only build a single variant. It's *much* more pleasant to work with trunk now ! -- ...ich hab' noch einen Koffer in Berlin...
