no, it does not. I know templates *NORMALLY* end up in the .s file after the compilation pass then the .o file after the assembly pass. if you actually read my email I said : > > the std::string template is ----> ****NOT**** <---- compiled into the .s file g++ does not seem to put the std::string template's code into the .o file like the other templates. it seem to NOT be instanciated in the .o file. I guess it would make sense to have the std::string class compiled once instead of in every file since its used everywhere, that would greatly speed up compile time but would cause problem in my case. I have the .s file right here and there is no assembly code for the std::string template's instance at all. my other templates are there, just not std::string. hence my question: where is it? and, if it IS precompiled, can I force g++ to compile td::string every time to see if that fixes the problem? -- Stephane Hockenhull SSC-Studios.com
