Hi,
While google suggest rewards for developing applications for Android,
there is an open source firmware named OpenMoko
(http://openmoko.org/).
I asked Michael Shiloh what are some of the requirement in building
apps in different compilers (FPC to be exact, and I also mentioned
Lazarus :)). Well "all" that is required is to bind ourself to the C
libraries.
I wonder what does it mean (other then binding) to make FPC and
Lazarus to support such environment.
I've been playing with that thought also (I've been following that
project for a while now). It supports X and gtk so that part should work
and AFAIK it runs some arm-linux so imo fpc could genererste some exe.
Since there wasn't an (easy) emulator environment, I stopped thinging
about it and didn't test.
OK, thinks have inmroved and you now can run a qemu emulator :)
I did some tests.
First, just using the gnu-arm-linux binutils, I compiled a arm-linux
trunk fpc and compiled a test (RTTIdump) console app. It runs fine on
the emulated moko.
Second I tried one of my simple test gtk2 apps. It compiles, but failed
to link since the gnu-arm-linux binutils don't understand the format
used for the X, gdk, gtk libs.
I should have done some more initial reading, since openmoko brings its
own binutils. After installing the openmoko toolchain I tried and
linking my testapp failed again. Now ld was complaining that the .o
files of the rtl had a wrong eabi version.
Sure, true, indeed, I forgot to recompile fpc.
And that ends in:
/net/thunder/mnt/mirror1/src/fpc/trunk/rtl/units/arm-linux/system.s:
Assembler messages:

It seems that the used arm core has no floatingpoint unit.
Does fpc support softfloat ? (if yes, how to use ?)
