Using Debian "Etch", which is arm rather than armel, I was able to compile FPC 2.2.2 running natively on an ARM system. I was subsequently able to use this to compile Lazarus 0.9.27, hence generate X applications natively. I can't remember whether I did any debugging.

Debian "Lenny" has switched to armel rather than arm. FPC 2.2.2 installs without error but trying to compile the canonical test.pas I get:

/usr/bin/ld: ERROR: Source object
/usr/local/lib/fpc/2.2.2/units/arm-linux/rtl/system.o has EABI version 0, but target test has EABI version 4

I think this is a fairly succinct indication of why I wasn't able to get FPC to compile itself prior to compiling Lazarus for Lenny.

Looking at the Debian "Lenny" repository, there is an fpc metapackage but the components- fp-compiler etc.- are not available.

From recent discussion I presume that to progress this I have to cross-compile, either on Debian "Etch" or on a non-ARM system. Can somebody point me at the information I need, and tell me explicitly what target I should be using?

Is there any way I can help by packaging an armel build for download, ditto for v2.2.3 for SPARC?

Well, actually no, did you try to bootstrap FPC itself? Then the program generated only contains files generated with the new binutils set.

Lenny is availible for both arm and armel.

Sorry, I'm not with you. I installed the same 2.2.2 binary that I'd previously used then tried to use that to compile the 2.2.2 sources. It didn't work, at which point I went back and did some more basic tests.

But the interesting stuff (nokia tablets, pandora) is armel

It sounded like you try to compile (actually: link) a new program for a armel 4 abi with a precompiled RTL for a armel 0 abi.

My suggestion would have been to try to recompile the RTL first with the binutils that come with the armel 4 abi system.

Thanks, Peter, I'll see if I can follow it up. I suspect that the problem is that the build tailored for the specific hardware I'm using is now armel-only and I've not got time to start working my way up the learning curve of repackaging the distro.

Yes, I think that's what's happening.

OK, I think I'm with that. Any pointers to documentation would be appreciated, I'm still at the stage of finding my way around.

Thanks, I saw some of that last night before I posted but there's more on gmane than in my local archive. I'll get back onto this later.

florian's done some more work on arm eabi and afaik it works if you compile without optimisations (-O-). this is using fpc trunk.

Yes. I uploaded a starting eabi compiler to
http://www.florianklaempfl.de/ppcarm

Please use only with -O-

Lovely. I've got to give up the disc in this machine which will knock me back a couple of days but I'll get back onto it as soon as I am able.
