It would be -lfile as the linker inserts 'lib' and adds on '.a'.

You'd need to add in the library directory C:\dev-cpp\lib, however,
for the linker to find it.

For example,

g++ -o test test.cpp -LC:\dev-cpp\lib -lfile

The -L says to look in C:\dev-cpp\lib for the library file
"libfile.a".  If the library file is in the same directory, you could
use -L. .
