Building Firmware under Cygwin

Prerequisites

Cygwin should be installed with at least the following packages:

• wget
• gcc
• g++
• make
• subversion
• unzip

Build Process

These are temporary instructions for building the reprap firmware under cygwgin.

• Run cygwin
• Choose a location to build the source. For now it should be somewhere without spaces in the path. /usr/src is a reasonable place to do this for now. From the windows filesystem point of view, this will typically be C:\cygwin\usr\src
• Issue the following commands
  • mkdir /usr/src    (just in case it doesn't exist - ignore the error if it already exists)
  • mkdir /usr/src/reprap
  • cd /usr/src/reprap
  • wget http://reprap.org/bin/viewfile/Main/SimonMcAuliffe?filename=cygwin-firmware.zip
  • unzip cygwin-firmware.zip
  • cd firmware
  • PATH=${PATH}:`pwd`/sdcc/bin    (note these are back-ticks not apostrophes)
  • make
• The output .hex files will be stored in subdirectories of C:\cygwin\usr\src\reprap\firmware\build\16f628

After changes to source code, subsequent builds can be executed by just re-running the make command.

If re-entering cygwin, to re-build you will first need to issue the following commands:

• cd /usr/src/reprap/firmware
• PATH=${PATH}:`pwd`/sdcc/bin

Then the make command can be executed as necessary.

Updating code to get the latest version

• cd /usr/src/reprap/firmware
• svn update devices
