chuck 1.2.1.3-1

Description:

Segmentation fault due to lack of '-fno-strict-aliasing' compile flag as discussed in this forum post: http://electro-music.com/forum/viewtopic.php?t=36259

Steps to reproduce:

Running just about any .ck script will result in direct segfault or other strange errors. For example:

$ echo "1 => int test; if (test) chout <= \"Seems like it works\" <= IO.newline();" > test.ck ; chuck test.ck
Segmentation fault

Quick, easy and tested fix:

Add to build() function in /var/abs/community/chuck/PKGBUILD:

CFLAGS="$CFLAGS -fno-strict-aliasing"

(makepkg -s ; sudo pacman -U)

$ echo "1 => int test; if (test) chout <= \"Seems like it works\" <= IO.newline();" > test.ck ; chuck test.ck
Seems like it works

I've applied this fix and now all my .ck scripts are running just fine. Many example .ck scripts for testing may be found here: http://chuck.cs.princeton.edu/doc/examples/

Additional information about this package:

1) The 64-bit version should be removed: http://chuck.cs.princeton.edu/release/

"note: ChucK currently supports only 32-bit systems; 64-bit support is not yet available (but we are working on it)"

2) There are multiple build options available (linux-alsa, linux-oss, linux-jack). The PKGBUILD script makes the ALSA version, but does not indicate this in the description, nor does it list alsa-lib as a dependency.
