wxruby users - Sep 2006 - Installation success, execution failed

Hello, after I wasn''t able to install wxruby via gem (404) I  
downloaded the file from rubyforge and installed it on my intel mac.  
No failure the so I tried to start the minimal.rb with ruby -r/r?/ 
ubegems <path>...
This didn''t work so I tried to do it in irb but the same error occured:

irb(main):001:0> require ''rubygems''
=> true
irb(main):002:0> load ''/usr/local/lib/ruby/gems/1.8/gems/wxruby2- 
preview-0.0.35-i686-darwin8.4.1/samples/minimal/minimal.rb''

when you simply run "ruby -rubygems minimal.rb" you get an error about
dyld not being loaded? That seems very strange.

After that, try: require ''wx''

That should load the wxruby2 library, without mixing in any possible 
problems with the minimal sample.

I wonder if the intel-mac WxWidgets library included in the gem has been 
built against the standard libpng instead of using the one bundled with wx?

I don''t have access to this platform but perhaps someone can have a
look
- the ./configure script for WxWidgets tells you which one it''s using 
when it finishes.

PS - I think we ran into a wrinkle with rubygems and the way the build 
tools version number is included on OS X gem filenames - when this was 
deleted, the gem command line tool can''t find the right package. This 
was tweaked since the last version so might well work better

I came across this the other day. To fix it, I installed libpng
through Darwin Ports, which put it in /opt/local/lib/libpng*, so I
then made a symlink from /usr/local/lib/libpng.3.dylib to
/opt/local/lib/libpng.3.dylib. This seems to solve the problem on my
box.

Ok, I missed the libpng, should be mentioned at http:// 
wxruby.rubyforge.org/wiki/wiki.pl?Installation. :)

Why WXRuby searches for the libpng in /usr/local... ? Aren''t there  
any ways/indices to find the location of this lib?

$ sudo gem install wxruby2-previewSelect which gem to install for  
your platform (i686-darwin8.7.1)
1. wxruby2-preview 0.0.35 (i486-linux)
2. wxruby2-preview 0.0.35 (i686-darwin8.4.1)
3. wxruby2-preview 0.0.35 (powerpc-darwin7.9.0)
4. Cancel installation
 > 2
ERROR:  While executing gem ... (OpenURI::HTTPError)
     404 Not Found

But the gem still couldn''t be found, tried to sysupdate my rubygems  
before this try.

Thanks and Regards

I think it''s a little glitch with the build, thanks for reporting the 
bug. The gems should be all-in-one and not have dependencies. I think 
people who are building gems just need to ensure that wxWidgets was 
built with:

--with-png=builtin

and similarly for tiff and jpeg; the output from ./configure says 
whether system or builtin versions will be used.

Could you send me the output of ruby -e ''puts RUBY_PLATFORM''

thanks
alex

I built the Intel Mac 0.0.35 gem but never tested it because I have
been very busy lately. When I built wxWidgets I did NOT specify
--with-png=builtin.

Hopefully I will get some time soon so I can fix my wxWidgets build to
generate working wxRuby gems.

Sorry for any inconvenience.

Maybe the wiki should have a page with how to build the
''APPROVED''
wxWidgets lib for each platform.

I''m not 100% sure that''s it, but it seems likely
then.

Sounds like the gem is fine apart from that. We''ll be happy to receive
a
gem whenever you have time. Much appreciated.

No worries. We didn''t know it would cause a
problem

Good idea

cheers

No problem Sean, I''m grateful to you for building it anyway.

Alex, I got this: i686-darwin8.7.1

These are the build settings I use on OSX (I added the --with-png=builtin)

cd to wxWidgets directory root
mkdir osx_build
cd osx_build
../configure --enable-debug=no --enable-shared=no --enable-static=yes
--enable-unicode --with-png=builtin
make -j 2
sudo make install
cd ..
mkdir osx_build_debug
../configure --enable-debug=yes --enable-shared=no --enable-static=yes
--enable-unicode --with-png=builtin
make -j 2
sudo make install

I use -j 2 on make since I have a dual processor machine.

I am building the Intel OS X 0.0.36 gem as I write this.
