make sure you have included string.h and also make sure your compiler knows the path for library

i have included string.h and the compiler sure knows the path of library as it was building earlier ok.

Post the code (use Improve question)around line 73 of your source file dir.cpp so we can see exactly what you are doing.

Solution 1

strlen is defined in libc.a
It should be done automatically, but make sure -lc is in the command line for the linker. I am not familiar with Eclipse for C++, but there is probably a project properties somewhere. Add -lc into the Additional Libraries setting.
