I recently installed MinGW on my 64-bit Windows 7 computer and when I attempt to compile the most basic of c++ programs, for example
#include
In just installed MinGW using the mingw-get-setup.exe v0.6.2beta-20131004-1 installer. Even though during the install I selected the gcc package, the installer didn't include the "mingw32-gmp" package, which includes libgmp-10.dll. I had to rerun the installer, chose the "Reinstall" option, and manually select the "mingw32-gmp dev" package.
