ruby/swig/svn load error

[Belorion]

I just finished installing the SVN binding for ruby using SWIG 1.3.24
(swig 1.3.25 wouldn't compile -- syntax errors).

I reconfigured an reinstalled Subversion (1.2.1) afterwards so that it
knew about the bindings (as per the instructions[1]). I did a `make
swig-rb` with no problems, a `make check-swig-rb` in which unit tests
are run, no problem. I did a make install-swig-rb.

However, when I do a `ruby -e 'require "svn/core"' I get this error:

/usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so:
libsvn_swig_ruby-1.so.0: cannot open shared object file: No such file
or directory - /usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so
(LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/svn/error.rb:1
from /usr/local/lib/ruby/site_ruby/1.8/svn/core.rb:3:in `require'
from /usr/local/lib/ruby/site_ruby/1.8/svn/core.rb:3
from -e:1:in `require'
from -e:1


Now, I can see libsvn_swig_ruby-1.so.0 in /usr/local/lib. Why can't it fin=
d it?

I don't know if this is relevant, but during the `make
install-swig-rb` I get a lot of these "warnings":

libtool: link: warning:
`/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../..//libdb-4.2.la' seems
to be moved
libtool: link: warning:
`/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../..//libexpat.la' seems
to be moved


Anyway, I can run all the unit tests just fine (which obviously use
the libraries) if I execute from
/usr/local/src/subversion-1.2.1/subversion/bindings/swig/ruby (as
root, due to permission issues), but from anywhere else I get the
above load error.

Anyone have any suggestions? I am using Ruby 1.8.2 (december build),
SWIG 1.3.24, and Subversion 1.2.1 on this Suse 9.2 box, and followed
the insructions from [1].

Thanks.

Hi,

"ruby/swig/svn load error" on Mon, 1 Aug 2005 08:30:53 +0900,

I just finished installing the SVN binding for ruby using SWIG 1.3.24
(swig 1.3.25 wouldn't compile -- syntax errors).

You can compile with SWIG 1.3.25 by applying the attached
patch. This change is included in trunk.

However, when I do a `ruby -e 'require "svn/core"' I get this error:

/usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so:
libsvn_swig_ruby-1.so.0: cannot open shared object file: No such file
or directory - /usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so
(LoadError) snip
Now, I can see libsvn_swig_ruby-1.so.0 in /usr/local/lib. Why can't it find it?

Could you show me the result of the following commands?

(1) % ldd /usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so

(2) % env LD_LIBRARY_PATH=/usr/local/lib ldd /usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so

(3) % env LD_LIBRARY_PATH=/usr/local/lib ruby -e 'require "svn/core"'


If (2) and (3) don't occur any errors, could you
re-configure with --prefix=/usr option?


Thanks,

I think you forgot to attach the patch . Where would I find it
online? I am browsing the CVS repository on sourceforge, but can't
seem to find the file I need.

If (2) and (3) don't occur any errors, could you

After doing those two things, the errors went away. (still using 1.3.24)

Thanks a lot for the speedy reply. Once I can find the patch for
1.3.25, I'll see how that one works.

I'm so sorry...
I really attached the patch this time!

Thanks Kou, the patch fixed the compilation issues with 1.3.25. Any
suggestions as to how to fix the library linking issue permanently, so
I don't have to do this ...

(1) % ldd /usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so

(2) % env LD_LIBRARY_PATH=3D/usr/local/lib ldd
/usr/local/lib/ruby/site_ruby/1.8/i686-linux/svn/ext/core.so

(3) % env LD_LIBRARY_PATH=3D/usr/local/lib ruby -e 'require "svn/core"'

Everytime? Thanks again.

Everytime? Thanks again.

Or add

/usr/local/lib

to /etc/ld.so.conf.


Or add

setenv LD_LIBRARY_PATH=/usr/local/lib

to your ~/.login. (if you use csh/tcsh)


Thanks,
