Hi, I'm having a problem while linking a dynamic library which was created using gcc with a .cpp file using the g++ compiler.Each time I link I get an error of undefined symbols. Here is the command : For creating dynamic library I use: gcc helloworld.c -dynamic helloworld #this creates a helloworld dynamic library. Here's the command to link: g++ hello.cpp -lhelloworld error : undefined symbol printhello Here helloworld is a library in which a function called printhello() is implemented which is used by hello.cpp. Please let me know if you have any suggesstions. johnsy
