I wanted to assemble https://github.com/sim-/tgy under Mac OS 10.9.5, error:
make tgy.hex
Pass 1...
/bin/bash: line 1: 729 Abort trap: 6 avra -fI -o tgy.hex -D tgy_esc -e tgy.eeprom -d tgy.obj tgy.asm 2>&1
730 Done | grep -v 'PRAGMA directives currently ignored'
make: *** [tgy.hex] Error 134
When I do the same thing under Linux (Ubuntu 14.04), it works OK.
What I am doing wrong under Mac OS with avra?
You are not doing anything wrong, this is the bug in avra.
It uses strcpy in an unsupported way in one place in the code, Linux is more forgiving on this.
I have uploaded a patch for this.
