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

[Elliott Slaughter]

I made three different compilation attempts. Hopefully one of them will give
us a lead as to what to try next.

When compiling with ./configure --host=armel --build=armel --with-fpe=no , I
get the following error:

if [ -f CROSS-COMPILER ]; then \
        touch ecl_min; \
    else \
        gcc  -o ecl_min cinit.o c/all_symbols.o -L./ libeclmin.a -leclgmp
-lm  -lgc;\
    fi
libeclmin.a(print.o): In function
`edit_double':/home/elliott/src/ecl-9.1.0-e/src/c/print.d:513: undefined
reference to `isfinite'
libeclmin.a(number.o): In function
`ecl_make_singlefloat':/home/elliott/src/ecl-9.1.0-e/src/c/number.d:158:
undefined reference to `isfinite'
:/home/elliott/src/ecl-9.1.0-e/src/c/number.d:158: undefined reference to

undefined reference to `isfinite'
:/home/elliott/src/ecl-9.1.0-e/src/c/number.d:181: undefined reference to
`isfinite'


Strangely enough, how far I get in the compilation process is determined by
what host and build settings I use. If instead I choose arm-linux-gnueabi,
which is what dh_make would have chosen, I get the following. (For some
reason, I don't appear to have gdb installed on the emulator, so I can't
really give you more information that this, although I suppose I could try
reinstalling the SDK if this seems important.)

if [ -f CROSS-COMPILER ]; then \
        ./CROSS-COMPILER compile; \
    else \
        ECLDIR=`pwd`/ ./ecl_min compile; \
    fi

Internal or unrecoverable error in:
Got signal before environment was installed on our thread.
  [22: Invalid argument]
/bin/sh: line 4: 10213 Aborted                 ECLDIR=`pwd`/ ./ecl_min
compile


Finally, I managed to compile on the device itself (after fighting to get
enough room to fit gcc), but the compiled binary crashed with the error
"Illegal instruction". I have attached a gdb backtrace, in case you can make
sense of it:

/media/mmc2 # gdb ecl
GNU gdb 6.8-debian
This GDB was configured as "arm-linux-gnueabi"...
(gdb) run

[Switching to Thread 0x4001fc40 (LWP 9556)]

(gdb) where

    argc=<value optimized out>,
    argv=<value optimized out>)
    at /media/mmc2/ecl/build/ECLINITSrP7rJ.c:50

Although I'm wondering if this failure wasn't really the result of using
different libc6 versions--since the only binaries I could find for armel
were the main debian repositories, I used libc6 version 2.7 and associated
binaries instead of the version 2.5 binaries the Nokia-provided SDK uses. As
such these results may not be worth anything.

(Actually, it confuses me that ECL can fail this badly after getting all the
way through the compilation process, considering that it has to load and run
ecl_min to even compile the rest of the executable.)

Again, thanks for your support.
