Help for nimble toolchain

(1/1)

caminati:
Hello, I am glad to see how much Robert advanced using his Debian import scripts.
I lately didn't contribute much to the port mainly because of lack of time, and secondarily because I was fancying about an alternative approach.

Basically, I hope to be able to bootstrap musl with only busybox, pcc and as binaries, like I can do on x86 linux.
The problem is that arm support for pcc existed briefly only for netbsd.
I successfully native-compiled on allwinner debian wheezy/sid some older pcc using the arm--netbsdelf.
That unexpectedly worked; however, when using the resulting pcc to compile musl I got different errors according to the pcc source version number: either


--- Code: ---op 75 slipped through

--- End code ---
OR

--- Code: ---compiler error: function '__builtin_stdarg_start' has no return type

--- End code ---
OR

--- Code: ---pcc -std=c99 -nostdinc -ffreestanding -fexcess-precision=standard -frounding-math -D_XOPEN_SOURCE=700 -I./arch/arm -I./src/internal -I./include  -Os -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack -falign-functions=1 -falign-labels=1 -falign-loops=1 -falign-jumps=1 -fno-stack-protector  -c -o src/aio/aio_readwrite.o src/aio/aio_readwrite.c
/tmp/ctm.pCEL0j: Assembler messages:
/tmp/ctm.pCEL0j:3: Error: bad expression
/tmp/ctm.pCEL0j:3: Error: junk at end of line, first unrecognized character is `0'

--- End code ---

Either the netbsd trick has some issue, or a nimble toolchain isn't possible on arm, as it is on x86.
I hope the former, of course.

Ideas? Anybody willing to experiment with that?
I already asked on pcc and sunxi lists, with only generic assurance that porting pcc  should be not much work.

I had a go at compiling pcc on my Hackberry Allwinner a10 following the general instructions at pcc.ludd.ldu.se (as perhaps you already had done on your hardware) as follows: (with build-essential, flex and bison already imported and loaded)                                                   
                                                           
import cvs   #Another import that works, as well as flex and bison....                                                                   
tce-load -i cvs/cvs.tcz                                                         
cvs -d :pserver:anonymous@pcc.ludd.ltu.se:/cvsroot co pcc                       
cd pcc   
./configure                                                                     
(... "checking" messages ....)                                                                             
configure:errror 'arm7l-unknown-linux-gnu' is not (yet) supported by pcc       

Not terribly encouraging, since the gcc, etc, are all debian versions.  Some way to confuse the configure operation, perhaps?

Thanks for your work on Allwinner a few months ago!

EDIT: Tried the same thing on Debian wheezy headless on Allwinner; same error message. /EDIT

Thanks for your work on imports, btw.

Yes, that is expected, since there is no support for arm linux.
That's why I resorted to using arm-netbsd, as I said.
