Tomas,
Which OS / arm board combination are you using?
Thanks,

Hi Alex,
attached is a patch to compile picolisp on arm out of the box. The -m32
switch doesn't seem to be defined there.
The -fPIC option was necessary for:
gcc -o ../lib/z3d -shared -export-dynamic z3d.o
/usr/bin/ld: z3d.o: relocation R_ARM_MOVW_ABS_NC against `a local symbol'
can not be used when making a shared object; recompile with -fPIC
z3d.o: could not read symbols: Bad value
collect2: error: ld returned 1 exit status
make: *** [../lib/z3d] Error 1
make: Target `picolisp' not remade because of errors.
Maybe there is a better way to handle the error?
Would it be possible to include it in the official version?
Thank you,
Tomas
