--- Comment #4 from r.menges at nice2cu dot de 2010-10-04 16:14:34 UTC --- (In reply to comment #3) > Please also show the error you're getting, as "crashes the application because > of a symbol-not-defined-error" is not very helpful > > I don't think this has anything to do with using a template function, I think > you've just built it wrong Actually i didn't write the makefile myself, it was generated by netbeans (6.7.). I am sorry, i was inexact about the error message: The symbol-not-defined is the error i see when using the original-code, which is executed in an apache context. The example simply crashes with an segfault. But you are right, the option -share is what caused the segfault in this example. After i removed the -shared option manually from the generated makefile, the example crashes no more. The "real" applications runs as an extension to php5 in the context of apache, it's an libary for c++-php-bridge we builded (so that c++-objects can be mapped into the space of php). This is where undefined symbol errors crashes the httpd-process with an error of undefined symbol, when using template<typename MsgType> void printMessage(MsgType msg); void printMessage(const char *); it misses the implemetation for std::string.
