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](http://rubyforge.org)
- wxWidget: “wxAll” from [wxWidgets.org/downloads](http://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.

Axel

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

[http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets](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.

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