Installing on openSUSE 11.1

Desktop wxRuby
1

Hello,

I try to install wxruby on openSUSE 11.1, but do not succeed.
I get an error, when trying to compile wxRuby; error message please see
at the
bottom of this message.

Using:

  • openSuse 11.1
  • wxruby: wxruby-2.0.1.tar.gz from rubyforge.org
  • wxWidget: “wxAll” from wxWidgets.org/downloads, compiled with
    “configure --with-gtk --enable-unicode” (no problem)
  • rake version 0.8.7
  • SWIG Version 1.3.36
  • ruby 1.8.7 (2008-08-11 patchlevel 72) [i586-linux]

Unfortunately, I have only very limited knowledge of linux and of
compiling and
no knowledge of any kind of C…

Using the wxRuby-gem and using wxwidgets.rpm from the
openSUSE-repository was
not successfull.

I use Ruby for hardware testing (quite a lot) and need some
graphical output of data values now.

I would be glad to get some help solving the above problem.

  • wxWidget: “wxAll” from Downloads - wxWidgets, compiled with

Please could you try configuring wxWidgets with the options listed here:

http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets

First, ‘make clean’ in the wxWidgets directory, then ‘configure’ with
the arguments listed on the page, then ‘make && sudo make install’.

You may need to install packages libmesa and libmesa-dev before
configuring wxWidgets to get GLCanvas support.

In particular, I think your problem is that wxRuby is trying to build
support for GL Canvas, but this isn’t available. The build process
should detect this and skip this, but clearly this hasn’t worked. Sorry
for the inconvenience.

  • rake version 0.8.7
  • SWIG Version 1.3.36
  • ruby 1.8.7 (2008-08-11 patchlevel 72) [i586-linux]

These all look fine. Please let us know if you’re still having problems.
