[Boost-users] boost builds dll's on mingw, can't use

Hi, I've been having problems linking to boost using mingw. I installed boost linking to mingw, but it installed the necessary boost-mgw files with either .dll or .lib extensions, which mingw can't use! I tried renaming the .lib's to .a's and the .dll's to .so's, which didn't work. then I tried adding a 'lib' prefix to each .a or .so, which still didn't work... there isn't actually a boost_thread library file, it's got some version number at the end - would that be a problem? Did I install it correctly? I'm linking to it using -lboost_thread in mingw (gcc). Any help much appreciated. Thanks, Imran
