Under OpenBSD 5.0 on amd64 with gcc 4.2.1 I get the following build error:

gcc -c -Wall -Werror -ansi -O3 -fPIC src/double.c -o obj/double.o
cc1: warnings being treated as errors
src/double.c: In function 'Qdouble':
src/double.c:27: warning: dereferencing type-punned pointer will break strict-aliasing rules
src/double.c: In function 'get_double':
src/double.c:44: warning: dereferencing type-punned pointer will break strict-aliasing rules

I get the following build failures with /bin/sh and /bin/bash on fedora 16 and mac os x 10.6. Any thoughts?

Trying to package Fexl for Arch Linux. Running into a slew of issues.

• You can't build as an unprivileged user.
• There is no equivalent to make DESTDIR=...
• It does not create /usr/bin or /usr/share if these locations do not already exist.

I've hacked around this using a unionFS sandbox so that ./build thinks it is writing to the root filesystem.

You can see the attempts at trying to fix these in
https://aur.archlinux.org/packages/fe/fexl-git/PKGBUILD

But even after after all this stuff, the REPL does not actually work.

I decided to take a look at Fexl again after...well it looks like 2 years based on my old issues. With my current pull request and 2 other OpenBSD specific tweaks (remove -ldl and nomove RTLD_NODELETE since OpenBSD doesn't need the former and doesn't support the latter) Fexl built and runs just fine on my amd64 OpenBSD -current system. One thing when I run .check a1 it seems the try (/ 0.0 0.0) test returns nan instead of -nan on my system any ideas?

Thanks.

I set up a FreeBSD v9.2 machine on VirtualBox, and fexl isn't working there. It builds fine, but then I try this:

$ bin/fexl
say "Hello world."
^D

The result:

Undefined symbol examine on line 12
Undefined symbol var on line 15
...

Basically it's unable to resolve anything in share/fexl/fexl.fxl.

I was hoping that compatibility between Linux and BSD would be a slam-dunk, but how wrong I was. I suspect a lot of it has to do with the usual path drama (e.g. "/proc/self/exe" and the like).

Evidently jturner has had a lot more luck than I running Fexl on BSD.
