It's a source code tarball. You need GNU bash to run its configure script, which is not included in codeblocks-mingw. > 3) Will I need a 64 bit version of libusb, for my system?

If you really want to compile a package yourself, get GNU bash, GNU make and GCC from MinGW/MSYS at first. Then just follow the package's INSTALL file. > I do sort of understand the basics but getting wrapped around the axel on > something.

How did Codeblocks invoke GCC? What did GCC or ld complain?
