Subj : Common C++ thread problem To : comp.programming.threads From : quaver Date : Tue Mar 22 2005 05:44 am Hello! I have problem with the thread-support of common-cpp. Here my code: #include #include using namespace ost; int main() { Mutex dataMutex; return EXIT_SUCCESS; } //end The error message I get is: main.o(.text+0x17): In function `main': /home/test/test/main.cpp:28: undefined reference to `ost::Mutex::Mutex[in-charge]()' I've installed the libcommoncpp2-dev My compiler is gcc3.3 (same error with 3.2) The whole Project is in KDevelop. My linker options are: -ldl -lccgnu2 Comiler Options: -I/usr/include/cc++2 Compiler Linker Flags: -L/usr/lib Does anybody have an Idea what I could have forgotten or what else could cause this error? Thanks, Dextro .
