run arduino-builder on ARM Linux box #76
Description
I am trying to do something fairly unconventional, which is trying to use arduino-builder on a Beaglebone Black (armhf single board computer) to build an Arduino sketch with the latest 1.6.6 Arduino files. arduino-builder is required, since the distribution itself is CLI only, no display (and no one has built an armhf port of 1.6.6). Here are the steps I have taken (all on a beaglebone):
- Cloned the latest Arduino master branch on Git to get the latest /hardware/ folder
- Installed the latest avr-gcc toolchain (4.8.1) to /usr/bin/
- Successfully built arduino-builder
- Created a test sketch which is an empty init() and a loop(){ Delay(1000); }
- Added the line "mega.build.mcu=atmega2560" to Arduino/hardware/arduino/avr/boards.txt, since it was missing for some reason and caused arduino-builder to error with an empty -mmcu flag
- Changed the following to fix an error:
compiler.path={runtime.tools.avr-gcc.path}/bin/
to
compiler.path=/usr/bin/
- Executed the following command:
./arduino-builder -hardware="/root/workspace/Arduino/hardware/" -tools="/usr/bin/" -fqbn=arduino:avr:mega -verbose test.ino
Following is the resulting output. The apparent error is "ctags pattern is missing"

ctags pattern is missing
I tried grepping through the arduino-builder folder, but couldn't find that specific error string anywhere. I then realized that the machine itself didn't have ctags installed, so I ran apt-get install exuberant-ctags, which added ctags to /usr/bin/ as well. No change observed.
Any ideas on how I might fix this problem?
Also, I notice that there is a arduino-builder/src/arduino.cc/builder/hardware/platform.txt file which sets the variables:
tools.ctags.path={runtime.tools.ctags.path}
tools.ctags.cmd.path={path}/ctags
tools.ctags.pattern="{cmd.path}" -u --language-force=c++ -f - --c++-kinds=svpf --fields=KSTtzns --line-directives "{source_file}"
Where are these being used? They aren't present in my Arduino/hardware/..../platform.txt file, and as far as I can tell, the arduino-builder executable doesn't know anything about the platform.txt file in its build folder (unless those options were built into it somehow when I ran the Go build?)
