[E3-hacking] Working (playing) from OS X

Hi, I bought one of the e3 emailers for a fiver a month or so back from a garage sale and have been having a play, on and off, since. However, I now no longer have a Linux box and only have a Windows laptop and an iMac G5 to work from. I have the necessary USB - RS232 adapter installed but cannot get pbltool.c to compile. I'm guessing this is due to it being written for the x86 architecture but I may well be wrong (as my c is useless). So, this is what I get: data:~/Desktop/Amstrad ayrea$ gcc -o pbltool pbltool.c /usr/bin/ld: Undefined symbols: _error _getline collect2: ld returned 1 exit status Any help would be appreciated, else I will just have to dual boot my laptop... Cheers Tony
