I'd suggest that you start off with Martin's binary, build the matching 2.6.4, FPC 2.6.4 has no support for EABIHF AFAIK. I have a patched 2.6.4 version with EABIHF support but I suggest to use FPC 3.0 or fixes_3_0 instead. I am sure Bo knows where to get it. ;-) Sources yes, I have checked out something like 4 different source trees by now. But the binaries are another deal... I fear you do not read my mails. http://sourceforge.net/projects/mseide-msegui/files/fpcarm/ Agreed, best place to start. What is EABIHF? The application binary interface of RaspberryPi. HF variant of the ARM (E)ABI. So you think that fixes_3_0 would be a better fpc on my RPi2? Yes.

Sure but the accustomed development environment (tools, documentation, version control, useful links, mail and mailinglists...) must first be installed and maintained separately. I find it much more convenient to use a single "every day" development environment for all tasks.

What I do find useful is being able to cut-and-paste between (programs running on) different hosts, which in practice either means running the IDE over SSH or having something running on each computer to implement a shared clipboard. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Hi all,
I have compiled a simple mips/linux application with using raspberry pi,

Illegal instruction.
Here is my application output and the source.

end.
Is there any special options for mips/linux to compile under arm/linux?
Thanks.
I think you need to give us more information about how you've built and
how you're invoking the compiler. Also I notice from
https://onion.io/omega/ that it runs OpenWRT, I'm not sure what the
situation is with this but I think you'll need to link in appropriate
runtimes.

Also I notice from https://onion.io/omega/ that it runs OpenWRT, I'm not sure what the situation is with this but I think you'll need to link in appropriate runtimes. On Linux we're using the syscall interface instead of libc, so for a simple program like the above this shouldn't be the problem. Propably the wrong CPU type was selected or something like that... But as you said we need more information. Regards, Sven ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
