Hi All, I am trying to build boost version 1_44_0 on Solaris.The Solaris box has Sun Studio 10 installed. The compiler details are bash-2.05$ CC -V CC: Sun C++ 5.7 2005/01/07 I am using the following command to build boost libraries *bash-2.05$ bjam --build-dir=/export/home/dfdev/Boost_1_44_0/boost_1_44_0/tmp/build-boost toolset=sun stage* But i get the below compilation errors, not even one of the projects build sun.compile.c++ /export/home/dfdev/Boost_1_44_0/boost_1_44_0/tmp/build-boost/boo st/bin.v2/libs/iostreams/build/sun/release/stdlib-sun-stlport/threading-multi/fi le_descriptor.o Notice: The Early Access serial number will expire in -7 days.

Am i missing something? Do i need to do any configuration changes? I will appreciate your input's. Regards, Nakul
