Hi Alex, Thank you for the reply.
I had the same issue on another machine. I was able to get this working by
changing the gcc args to -m32 in lib/native.l instead of -m64
(apply call L 'gcc "-o" (tmp Nm)
"-fPIC" "-m32" "-shared" "-export-dynamic"
"-O" "-falign-functions" "-fomit-frame-pointer"
"-W" "-Wimplicit" "-Wreturn-type" "-Wunused" "-Wformat"
"-Wuninitialized" "-Wstrict-prototypes"
"-pipe" "-D_GNU_SOURCE" (tmp Nm ".c") ) ) )
I was then able to call cFibo successfully
joe@joe-linux:~/tmp/picolisp$ ./pil +
: *CPU
-> "emu"
: (load "misc/fibo.l")
-> NIL
: (cFibo 3)
-> 2
: cFibo
-> ((N) (native "/home/joe/.pil/tmp/7311/fibo" "Fibo" 'I N))
:
I don't know enough about this to offer an opinion on whether -m64 is
appropriate on a 32bit machine. It sounds like it's possible to cross
compile to 64 bit with supporting libraries but I don't think it'd be
possible to execute it.
