Hi, I am trying to compile/install boost libraries (1.35.0 version) and some erros appears in console: # ./configure --without-icu --with-libraries=regex,filesystem Building Boost.Jam with toolset qcc... tools/jam/src/bin.qnxntox86/bjam Unicode/ICU support for Boost.Regex?... disabled.

Not all Boost libraries built properly. Does anybody know how to solve this? My qcc/QCC is set to 3.3.5,gcc_ntox86. The same error appears when i try with bjam Thanks Ricardo ____________________________________________________________________________________ You rock.
