Hi,

I was just fiddling with the ABI_v1 build system and I tried to give it a new target "raspberrypi-(arm/thumb)"

Here's what I've done, is it now really that simple to create crosscompiler for Aros or am I missing something?






If it is that simple then next thing would be to code bootstrap code... GCC is still building so I don't know what the result will be

Nope, it needs a lot more...

Building AROS/Libs/version.library ...
/opt/aros-arm/arm-aros-ld: /home/ubuntu/AROS.raspberrypi-arm/bin/raspberrypi-arm/gen/compiler/libinit/libentry.o: compiled for a little endian system and target is big endian

Edit: Stupid me, let's just give the elf object a correct flag in configure > aros_object_format="armelf_linux_eabi"

And now we fail with

Linking AROS/Tests/getcpuinfo...

Error: Error while running make in test: No such file or directory
make: *** [all] Error 10

Edit: gcc flags should take care of that

Edit: I fear that the cross compiler needs some patches... or it needs to be configured differently

Edit: Let's mess with the cross tools compilation and declare --without-system-libunwind

Edit: Nope, --disable-libunwind-exceptions ?

Edit: I'm getting nowhere...

Edit: Bypassing getcpu the next one failing is AROS/Tests/benchmarks/graphics/pixelarray... but a lot of code compiles in between

Edit: Bypassing pixelarray the next one failing is AROS/Libs/uuid.library

All these fail the same as getcpu (no __cxa_begin_cleanup etc.)

Googling a bit lead me to belief it's a gcc bug with 4.5-4.6 versions

Running FILE with one of the build librarys tells me this:

Edit: Building HDToolbox fails when uuid.library is bypassed as it depends on it

Edit: Next one failing is AROS/Tools/ShowConfig

I'd like the native Rasperry Pi to run solely on thumb instruction set, I'll try that next. Maybe it will bypass that GCC bug with version 4.6.2 or not.

Quote:

There is no strange bug in gcc 4.6. Look at the nightlies, the arm version is built every night using gcc-4.6.2 crosscompiler (built together with AROS).

Not to mention that I've successfully built armel and armhf linux hosted targets here at home. No problem with that.

Regarding native rpi port - why don't you look at arm linux hosted and start there? Why do you try to create separate crosscompiler at this stage? Use the one AROS builds. Look at the linux-arm entries in configure script, or even at the efika entry which I started to work on. That should be your starting point I think...

BTW: You will need to link against aeabi library too

This is now taken from configure.in

aros_kernel_ldflags="-mthumb"
;;

This is all just a mental exercise, nothing to take serious about.

I should have really looked closer at the configure and the mmakefile which does the crosstool.

This is the Aros cross compiler not any separate one.

With these those undefined symbol errors are gone, still need to make gcc not to throw error on [-Werror=implicit-function-declaration]

/home/ubuntu/aros_svn/trunk/AROS/workbench/devs/monitors/IntelGMA/galliumclass.c:198:5: error: implicit declaration of function ‘HIDD_BM_OBJ’ [-Werror=implicit-function-declaration]

Now that it compiles it's time to tune it to the platform (It builds everything at the moment)

Edit: For the good or worse it still emits Arm code by default, I thought I had enough -mthumbs in there...

Edit: Created arm-raspberrypi in arch with boot folder, efika as reference

Edit: First thing to code would be the boot code and serial driver for debug purposes.

While trying to figure out the arch specific code, I get thrown with this:

Linking gen/kobjs/kernel_resource.o
There are undefined symbols in '/home/ubuntu/AROS.raspberrypi/bin/raspberrypi-arm/AROS/boot/aros-raspberrypi':
U __LIBS__symbol_set_handler_missing
U __PROGRAM_ENTRIES__symbol_set_handler_missing

Is this the cause? Should I configure the crosstools differently to get rid of it... Removing exception handling?

http://infocenter.arm.com/help/index. ... oc.dui0203j/Cacdfeci.html

Edit: Oh... I think I switched them off already with the --disable-sjlj-exceptions switch while making the compiler

Let's add -fno-exceptions to cflags

Edit: Culprit wasn't GCC, but I suspect my UglyHackMonkeyCode(tm)... compiler/include/aros/symbolsets.h contains macro "THIS_PROGRAM_HANDLES_SYMBOLSET(x)" which emits those undefined symbols. -> genmodule.h ? collect-aros...

Calling "make raspberrypi-image" creates a 4 byte file called kernel.img from boot.o

8000: eafffffe b 8000

That's just a while(1); eg. branch to itself... All this for just 4 bytes worth of code... :)
