------------------------------

             Summary: Failed to build with SWIG 4
                 Key: SVN-4818
                 URL: https://issues.apache.org/jira/browse/SVN-4818
             Project: Subversion
          Issue Type: Bug
          Components: bindings_swig
    Affects Versions: 1.12.0
         Environment: Arch Linux x86_64, SWIG 4.0.0.
            Reporter: Felix Yan


The Python binding failed to build with an error:

{{Deprecated command line option: -classic. This option is no longer supported.}}

 After fixing this (by removing -classic from build.conf), a lot of new errors like below appeared:

{{subversion/bindings/swig/python/svn_client.c:6201:128: error: ‘svn_argnum_swig_obj’ undeclared (first use in this function); did you mean ‘svn_argnum_obj1’?}}

After looking up the changelog of SWIG 4, it appears fastunpack becomes default so I added {{-nofastunpack}} to get around this.

Next error is inside Ruby bindings:

{{subversion/bindings/swig/ruby/svn_client.c:1605:21: error: ‘SWIG_POINTER_NO_NULL’ undeclared (first use in this function); did you mean ‘SWIG_POINTER_OWN’?}}

Looks like the vendored proxy/*.swg files are outdated. I removed some and get passed this one.

Finally it built fine, but I am stuck at the test suite now. The python binding failed to import correctly:

{{File "/home/felix/projects/arch/packages/subversion/trunk/src/subversion-1.12.0/subversion/bindings/swig/python/libsvn/core.py", line 32, in _swig_setattr_nondynamic}}
{{method = class_type.__swig_setmethods__.get(name, None)}}
{{AttributeError: type object 'svn_auth_cred_simple_t' has no attribute '__swig_setmethods__'}}

Please let me know how to proceed, thanks!
