The Linux C++ STL (Standard Template Library) is not threadsafe. I'm working on a project where I will need the functionality of the STL but it also must be threadsafe. Currently, the only Rogue Wave® SourcePro® C++. I've used this before, and the company I am working with has used it in some of their products, but their version is several years old. Other than STL, Rogue Wave® contains libraries for things like Linear Algebra (LAPACK). What I would like to know is if there are other good commercial (or OpenSource) threadsafe STLs. BTW: The C++ standards committee will probably never endorse threadsafeness. -- Jerry Feldman <gaf@blu.org> Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9
