Things would be far easier if there were still such things as ARM-based workstations, i.e. booting from an external device (USB or whatever) rather than internal Flash. The boards I've got are made by iEi, but you get either CE or Linux- not both. I'm hoping to be able to hack OpenFirmware onto a CompactFlash card which would give it much the same interface as Suns and PPC-based Macs.

It's best to compile 2.4.0 with -dFPC_ARMEL (no need to use -CaEABI) and use the resulting compiler. Thanks Jonas. It's worth noting that the hardware is an NLSU2 Slug, so uname -a reports I've managed to get trunk working on my slug (also on debian lenny) quite a while ago, so I hope it's still possible.

Thanks Henry. I've definitely had both FPC and Lazarus running natively on ARM in the past, but I suspect it was on Etch and that I ground to a halt when Debian started forcing the EABI transition. I do remember that I had a demo program for a Velleman K8055 interface board working on x86, SPARC and ARM... can't remember whether I ever tried it on PPC since I've only got a system fairly recently. Is my recollection correct that somebody's working on the MIPS port? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

For example, if I say fpc -i to 2.4.0 I get ..
