Hi, I am trying to build boost_1_34_0 on Solaris 10 using Sun C++ 5.8. Sun C++ 5.8 requires "-library=stlport4" for successful build of boost_1_34_0. However, by default bjam is using the standard library. How do I pass <stdlib>sun-stlport option at command line ? Currently the only way (as per the instructions @ http://blogs.sun.com/sga/ category/Boost ) is to create user-config.jam with following contents --------------------------------cut here---------------------------------- import toolset : using ; using sun : : /db2/sunstudio11/SUNWspro/bin/CC : <cxxflags>-library=stlport4 <cxxflags>-features=tmplife <cxxflags>-features=tmplrefstatic <linkflags>-library=stlport4 ; --------------------------------cut here---------------------------------- regards, Prashant Thakre
