Hi Cle,
Hi Alexander,
unfortunately, we see problems on Mac OS since quite some time.
You'll see that if you search in the archive of this mailing list
(http://www.mail-archive.com/picolisp@software-lab.de).
I had already seen this, but those problems dealt with being not able to
build picoLisp though. Therefore I had the hope, that my problem perhaps
is already solved! :-}
I don't have a Mac myself. So I'm still hoping that some of the Mac
users fires up a debugger and helps, but no results so far :-(
Ok! Today I had give it a try and finally I was able to patch and build
picoLisp to being runable under Snow Leopard passing all unit tests in
lib/test.l and running doc/hello.l and doc/family.l too :-)
I have attached the patch necessary to fix all glitches for Snow
Leopard. I have tested the changes against Snow Leopard and NetBSD and
they work fine! I intend to have a look, if they run under Leopard
(MacOS/X 10.5) tomorrow if I can manage to install Xcode on my PPC machine.
BTW: If you duplicate the OpenBSD section in the src/Makefile and
replace OpenBSD by NetBSD, you can add another platform picoLisp is
running onto :-D
The attached patch was made against the development version downloaded
as picoLisp.tgz from your homepage. The patch was applied as:
tar xzf picoLisp.tgz
cd picoLisp
patch -p0 < ../picoLisp.patch
(cd src; make clean picolisp)
./p lib/test.l -bye
I hope, I did not break your coding style too much via the patch ...
Best regards and thanks for picoLisp ... :-)
Ciao,
Cle.
