Welcome to the forum, and thanks for the post.

What flavor of Linux and which version of GCC are you using?

Regards,
Mark

Thanks, I forgot to add the details: Gentoo (amd64) and gcc-4.3.4.

Hi Reto,

I have tested Ice Ruby on Gentoo 64 and was not able to reproduce the problem, our setup are very similar, seems to me that differences in CXXFLAGS could be the cause of this, we will further investigate that and include a fix in 3.4 release.

Hi Reto,

actually i was wrong about CXXFLAGS, as Ice source distribution doesn't use portage CXXFLAGS to build.

What ruby version were you using?

i have that:

[ebuild   R   ] dev-lang/ruby-1.9.1_p243  USE="berkdb gdbm ipv6 ssl -debug -doc -emacs -examples -rubytests -socks5 -tk -xemacs" 0 kB

Bests Regards,
José

Reto Glauser · February 2010

Hi José

nice catch. Unmasking, keywording and installing ruby-1.9 seems to do the trick:

# echo "=dev-lang/ruby-1.9.1_p243" >> /etc/portage/package.unmask
# echo "=dev-lang/ruby-1.9.1_p243 ~amd64" >> /etc/portage/package.keywords

even though ruby1.8 is still active:

# eselect ruby list
Available Ruby profiles:
  [1]   ruby18 (with Rubygems) *
  [2]   ruby19 (with Rubygems)

Looks like Ice-3.4b depends on ruby1.9 ?

Looks like Ice-3.4b depends on ruby1.9 ?

Ice For Ruby requires ruby >= 1.8.1

In my other gentoo setup (x86) it builds fine with 1.8.7

Available Ruby profiles:
  [1]   ruby18 *
pepone@marte /usr/src $ ruby -v
ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-linux]
pepone@marte /usr/src $ gcc-config -l
 [1] i686-pc-linux-gnu-4.3.4 *

What Ruby 1.8 version do you have?

Bests Regards,
José

Reto Glauser · February 2010

I don't have a x86 gentoo, but a second x86_64:

$ uname -a
Linux i7 2.6.31-gentoo-r6 #19 SMP Wed Dec 23 19:24:02 CET 2009 x86_64 Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz GenuineIntel GNU/Linux

and both fail with 1.8.7_p249

     Available versions:
        (1.8)   1.8.6_p388 1.8.7_p249

xdm · February 2010

I was able to reproduce the bug in gentoo linux x86 and x86_64 with

dev-lang/ruby-1.8.7_p249 and gcc-4.3.4

Previous 1.8.7 versions seems not affected, ruby 1.8.7 (2009-06-12 patchlevel
174) just works fine.

We will include a fix in 3.4.0 final release.

Thanks for point this out, and help to track it down.

Bests Regards,
José
