so I was trying to build a C++ project, but then I get this error
**** Build of configuration Release for project p ****
**** Internal Builder is used for build
You should add "msys" path (C:\MinGW\msys\1.0) to tour project along with MinGW path (C:\MinGW\bin). Then build goes fine.
Had this exact same problem today, but luckily I found a video which sorted it out for me. Seems we weren't properly installing MinGW.
