wxruby users - Aug 2006 - Compiling WxRuby2 on Ubuntu 6.06

Hi All,

I am trying to compile WxRuby on Ubuntu 6.06. I checked out the latest
source code from CVS and ran ''rake'' under the wxruby2
directory. I am
getting the following error.

root@imayam:/work/wxruby/wxruby2# rake
(in /work/wxruby/wxruby2)
rake aborted!
Don''t know how to build task ''src/App.cpp''

(See full trace by running task with --trace)

I am totally new to SWIG and have absolutely no idea what is going
wrong.

The following is my environmental setup

1. Ruby 
root@imayam:/work/wxruby/wxruby2# ruby -v
ruby 1.8.4 (2005-12-24) [i686-linux]

2. Rake
root@imayam:/work/wxruby/wxruby2# rake --version
rake, version 0.7.1

2. GCC
root@imayam:/work/wxruby/wxruby2# gcc -v

Please see http://www.swig.org for reporting bugs and further
information

4. GTK
root@imayam:/work/wxruby/wxruby2# pkg-config --modversion gtk+-2.0
2.8.20

5. WxWidgets
root@imayam:/work/wxruby/wxruby2# wx-config --version
2.6.1

Please let me know if I am missing something or if I need to install any
other prerequisites. I am seriously considering WxRuby for my inhouse
projects and eventually write a self published book. 


Cheers,
Ganesh Gunasegaran.

Very strange. I also use Ubuntu 6.06. Actually, I have it on my desktop
(where I do wxruby development) and my laptop, where I have not done any
wx development. So I tried to compile wxruby2 on my laptop, and here are
my notes:

- Used cvs to checkout the wxruby2 module from rubyforge
- I already had rake 0.6.2 installed, so I used it
- Downloaded swig 1.3.29, ran ./configure; make; sudo make install
- Obtained libwxgtk2.6-dev package using Synaptic (apt)
- Obtained ruby1.8-dev package using Syaptic (apt)

At that point, rake successfully started to build wxruby2, going well
past App.cpp. I upgraded rake to 0.7.1 (gem update rake), and it still
seemed to work. (I got a compile error in RubyConstants.cpp because of
wxID_NONE, which I will look into now. Might be a wx 2.6.1 vs. 2.6.3
thing).

It would probably help if you could run rake --trace to get more
details.

Unfortunately, we require SWIG 1.3.29, as it has some very substantial
improvements over 1.3.27. I don''t think this should cause the
particular
error you are seeing, however.

I normally use 2.6.3, but 2.6.1 may work. Even if not, this should not
cause the rake error you are seeing.

Great. I believe we will be able to get it working for you.

It is. wxID_NONE was added in 2.6.2. I would really like to support wx
2.6.1 since it is in Ubuntu 6.06. I see four options:

1. Remove support for wxID_NONE. Great for 2.6.1 users, but bad for
2.6.3 users.

2. Only support wxID_NONE when compiled against wx 2.6.3. This would
mean that wxRuby apps couldn''t rely on having it available.

3. Define wxID_NONE ourselves if it is not available. However, certain
API calls that have defined behavior for wxID_NONE would not work when
running on wx 2.6.1. So it would appear to be available, but wouldn''t
really work.

4. Require wx 2.6.3.

5. Link wx statically into wxruby. Obviously this would make the gem
larger. And in the past, when I have attempted static linking, I have
struggled. So I''m not sure how long it would take to get it working.

It looks like gentoo, Fedora FC-4, and Debian[1] all have wx 2.6.2. So
it''s just Ubuntu that is a problem.Bummer.

I will look into option #5 today. If that doesn''t work out,
I''m not sure
which option I would favor.

I agree this would be preferable. I am pretty sure that when I build wxruby
it includes statically linked wx. It actually ran into problems unless 
wx was
built with --enable-static --disable-shared

but the unstripped binary is ~12MB...

I believe I have succeeded in building a Linux gem with wx 2.6.3 built
in statically, so it will work on systems like Ubuntu that have older wx
libraries, or no wx at all. I have tried it on one other computer, but
would love to have a couple other users test it privately before
publishing the gem more widely.

So, if you have a Linux box, and would be willing to try downloading the
gem (25 megs), installing it, and doing a bit of testing, please let me
know. The ideal tester for this is someone who has NOT yet built wxruby
from source, but at this point I''ll take any testers I can get.

Email me off-list ( wxruby at qualitycode.com ), briefly describe your OS
environment, and I''ll send you the link.

Thanks!

Kevin,

I also have the same problem, but on FC5. I get the following output 
when running rake -

I checked out the CVS and typed rake and got the following (with --trace) -

I am running FC5, with wxWidgets-2.6.3 installed from source.

Ok, so that''s the problem. If you have a too-old SWIG, for some reason
rake fails to output useful information. Even with --trace enabled, the
output is really poor.

Could you (or someone) enter a rubyforge bug for that. Hopefully then
someone can fix it easily, since it is pure ruby code in the rakefile.
No knowledge of C++ or SWIG or even wxruby is required.

I don''t think this is a showstopper for the alpha release, since the
alpha release is primarily about the binary gems, not the source
tarball.

Thanks,

Kevin

Hi Kevin,

Thanks for the reply. The problem seems to be in the SWIG version I had.
I happened to have SWIG 1.3.27 installed thro'' Synaptic Package
Manager. 

I downloaded and compiled SWIG 1.3.29 from source and then ran rake.
WxRuby compilation went thro'' just fine.

Cheers,
Ganesh Gunasegaran.

Hi All,

Now ruby is not able to load wxruby2 library :( 

root at imayam:/work/wxruby/wxruby2/samples# irb
irb(main):001:0> require ''wx''
Unable to load wxruby. Searched
/usr/lib/ruby/site_ruby/1.8
/usr/lib/ruby/site_ruby/1.8/i686-linux
/usr/lib/ruby/site_ruby
/usr/lib/ruby/1.8
/usr/lib/ruby/1.8/i686-linux

I have checked that the wxruby2 libraries are indeed present in the
search path.

root at imayam:/usr/lib/ruby/site_ruby/1.8/i686-linux# ls wx*
wx.rb  wxruby2.so

I then tried to load wxruby2 directly and got this

irb(main):002:0> require ''wxruby2''
LoadError: libwx_gtk2_xrc-2.6.so.0: cannot open shared object file: No
such file or directory
- /usr/lib/ruby/site_ruby/1.8/i686-linux/wxruby2.so
        from /usr/lib/ruby/site_ruby/1.8/i686-linux/wxruby2.so
        from (irb):2

So it looks like there is something wrong with my WxGTK installation? I
compiled WxWidgets 2.6.3 from source.

root at imayam:/work/wxruby/wxruby2/samples# wx-config --version
2.6.3

If I am not able to resolve this issue, Kevin do you mind sending me the
link to static linked gem you were mentioning? I would be happy to test
it out. 

Cheers,
Ganesh Gunasegaran.

Never mind. WxWidgets seems to be installed in /usr/local/lib, which was
not included in the LD_LIBRARY_PATH for my root login. After
including /usr/local/lib in LD_LIBRARY_PATH samples work fine. Sorry
guys, my bad!!

I will hopefully give wxruby2 a good spin. Thanks for the great work.

Have filed a bug for this, will have a shot at submitting a patch later this

Great, well done. Did you have to change anything in our build system, 
or just change the options that WxWidgets is built with?

If anyone has an OS X PPC system, it would be great if you could try out 
a pre-release gem to check it has everything. Drop me a line off-list 
(alex AT pressure DOT to)

I created a new wxWidgets configuration, built it, selected it with
wx-config, and un-commented the rakelinux.rb code that (apparently) had
worked for me before.

I did a bunch of searching the web to try to figure out the secret of
having multiple wx builds on my system. The answer was in the INSTALL
file that ships with wx, but nothing on the web pointed me there. I
finally found it when I abandoned the web and looked at the wx README.
Even there, it''s not documented as well as I would like. But it worked.
