I installed MinGW and MSYS on my Windows 7 computer. I added C:\Program Files (x86)\MinGW\bin to my path. Commands such as gcc and g++ work, but make does not. I looked in the directory, and there is no executable called make, even though I installed all components. There is a file called mingw32-make. There are also other files prefixed with mingw32-, such as c++, g++, gcc, gcc-4.6.1, and gfortran. However, there is a make in C:\Program Files (x86)\MinGW\msys\1.0\bin.
If I open the MinGW Shell and type in make, make executes. However, it does not execute from the Windows terminal.
Is this intentional, or could I be missing other executables as well? Should I just add C:\Program Files (x86)\MinGW\msys\1.0\bin to my path?
Yup, add the msys bin directory to your path (after MinGW's bin dir). That's exactly what the MinGW shell does and why it works there.
Try gmake. Sometimes the GNU version of Make installs itself as gmake in order to distinguish from non-GNU Make.
C:\Program files\xxx has spaces in it! Since shell scripts are involved, spaces are significant and have to be escaped. Hence this path will not work with mingw. The documentation recommends to install MingW in C:\MingW.
