[Ecls-list] Help cross-compiling ECL for ARM EABI (was: Can ECL run on the Nokia S60?)

[Elliott Slaughter]

Hi,

I'm trying to cross compile ECL for Linux on ARM EABI, and have run into
some problems, the end result being that ECL crashes on the target device. I
would appreciate any assistance in debugging or getting this build to work.
Thanks in advance.

I have outlined my steps below (some of this may or may not be related, so
please stay with me):

I am compiling using a x86 Linux machine to a Nokia n810 running Maemo (a
Linux derivative) on ARM EABI, using the Maemo SDK+ toolchain. I am trying
to compile ECL from the newest CVS, using an ECL I just built from CVS on
the build machine.

When I started the cross compile, I didn't know what values were appropriate
in cross_config for ARM processors, so I just left the defaults. (I can't
find any references online for this, so I still can't check whether they
were correct or not.) If any of the following configuration settings are
wrong, please let me know:

ECL_STACK_DIR=up
CL_FIXNUM_TYPE=int
CL_FIXNUM_BITS=32
CL_FIXNUM_MAX=536870911L
CL_FIXNUM_MIN=-536870912L
ECL_BIGENDIAN=no
ECL_NEWLINE=LF
### 1.5) Can we guess how many characters are available for reading from
###      the FILE structure?
###          0 = no
###          1 = (f)->_IO_read_end - (f)->_IO_read_ptr
###          2 = (f)->_r
###          3 = (f)->_cnt
ECL_FILE_CNT=0
ECL_TO_RUN=/usr/bin/ecl

Continuing, the build process seemed to go well enough, except for a failure
to compile defsystem.lisp:

;;; No class named TOPOLOGICAL-SORT-NODE.
;;; Error: in file ext:defsystem;defsystem.lisp, position 117, and form
;;;   (DEFINE-STRUCTURE 'TOPOLOGICAL-SORT-NODE 'TOPSORT- ...)
;;; The form (SI::DEFINE-STRUCTURE 'TOPOLOGICAL-SORT-NODE 'TOPSORT- 'NIL
'NIL '((COLOR :WHITE :TYPE (MEMBER :GRAY :BLACK :WHITE))) '((COLOR :WHITE
(MEMBER :GRAY :BLACK :WHITE) NIL 0 NIL)) 'COPY-TOPOLOGICAL-SORT-NODE 'NIL
'NIL 'NIL '(MAKE-TOPOLOGICAL-SORT-NODE) '1 'NIL 'NIL
'TOPOLOGICAL-SORT-NODE-P) was not evaluated successfully.
Cannot find out entry point for binary file
;;; You are recommended to compile again.Broken at TOP-LEVEL. File:
#P"/home/elliott/src/ecl-9.1.0/src/lsp/top.lsp" (Form #26)No restarts
available.

I figured I could live without defsystem, so I continued and finished the
build.

The build compiled, and I built a debian package and attempted to install it
on the phone. I immediately found out that I was missing libgc1c2. Using
lenny debian sources, I found a binary, with one minor problem: it depended
on libc6 >= 2.7 and the device comes with 2.5. Hoping it would work anyways,
I installed libgc1c2, and then ecl. When I ran ecl, I got the following
error:

# ecl

Internal or unrecoverable error in:

Lisp initialization error.

  [22: Invalid argument]
Aborted

Hoping to find out more about this rather opaque error, I installed gdb and
got a backtrace:

   from /usr/lib/libecl.so.9.1
#3  0x4011b19c in ?? ()
   from /usr/lib/libecl.so.9.1

Which still leaves me with no clear idea of what exactly is going wrong.

Given the above information, what seems the most likely cause of the error?
How might I be able to get better information for debugging?

Do I need to worry about compatibility with the libc version? (I have tried
and failed to upgrade libc on the device, so if this is the issue than I
probably need to go and compile libgc1c2 for the old libc, not the other way
around.)

Does anyone have recent experience with compiling ECL for an ARM (especially
EABI) device? Are there any known issues involved? Does anyone currently
have a working binary?

Thanks again. Any assistence would be appreciated.
