Symbol not found: _mrb_sym2str

After I update my mruby and nginx with the latest master (v2.2.0) start to get following failure?

nginx: [emerg] dlopen() "/usr/local/nginx/modules/ngx_http_mruby_module.so" failed (dlopen(/usr/local/nginx/modules/ngx_http_mruby_module.so, 10): Symbol not found: _mrb_sym2str
  Referenced from: /usr/local/nginx/modules/ngx_http_mruby_module.so
  Expected in: flat namespace
 in /usr/local/nginx/modules/ngx_http_mruby_module.so) in /usr/local/nginx/conf/nginx.conf:12

Anything changed for build process?

Thank you for your report. I think this issue is a mruby specification. Please issue to mruby repository.

Thank you for your report. I think this issue is a MRuby specification. Please issue to MRuby repository.

I have created issue for a MRuby repo with following url
mruby/mruby#4934
, But I'm still not sure why Travis test environment looks like works fine not my local. Maybe some OSX or Clang issue?

@matsumotory I could solve this issue. When I delete mruby build folder (old version) the it's building correctly.
That's mean .minirake clean not working for version update. What do you think if I add some shell in build.sh to delete mruby build folder if version different than current one.

[matsumotory]

That sounds good. Could you send the PR?

Seems like with new version might need to specify build_config as like as follows.
rake clean MRUBY_CONFIG=NGX_MRUBY_ROOT/build_config.rb
According to answer of mruby issue

@Zogoo I believe db45048 fixes the issue.
