Hi, I'm new to Boost and while trying to build it on Solaris 10 using the sun Toolset and the and Sun Studio 12.1 compiler I'm running into this issue: sun.archive bin.v2/libs/exception/build/sun/release/link-static/stdlib-sun-stlport/threading-multi/libboost_exception.a "CC" -xar -o "bin.v2/libs/exception/build/sun/release/link-static/stdlib-sun-stlport/threading-multi/libboost_exception.a" "bin.v2/libs/exception/build/sun/release/link-static/stdlib-sun-stlport/threading-multi/clone_current_exception_non_intrusive.o" common.copy stage/lib/libboost_exception.a cp "bin.v2/libs/exception/build/sun/release/link-static/stdlib-sun-stlport/threading-multi/libboost_exception.a" "stage/lib/libboost_exception.a" ...failed updating 4 targets... I'm kinda stuck here. What could be the reason for this error? Ihsan -- ihsan@dogan.ch http://blog.dogan.ch/
