Build environment for BrailleBuzz (the GNU tool-chain for STM32F103) January 29, 2015

I am documenting from memory here, I did this over a year ago and have just now gotten round to documenting it. There are a bunch of things I gloss over and one or two inaccuracies that I am miss-remembering. Nevertheless, this should give you a clue and along with the excellent documentation over at gnu.org it should get you going. Of particular use are my bash scripts, read them, understand them, and optionally use them verbatim. Also use the docs on the olmex site. I used those development boards to bootstrap this project they are excellent! I don’t know if it’s the “right” way but what I did was to create a usr directory off my home directory. While I have root on my box, and everything else around here, my goal was to avoid using it so that I could simply zip it up and hand it off to another developer; which is what I have recently done.

Under src one puts the source for the various tools, e.g. binutils, gcc, gdb, openocd, speex, and gmp, mpc, mpfr; the latter three are prerequisites for gcc.

Next one creates a build directory under usr. Under build one creates directories for each of the utilities enumerated below. I also played some games with soft links to facilitate version upgrades later:
