I’m trying to get eRuby and mod\_ruby running on OS X (Panther). mod\_ruby seems to be working fine, but if I try to enable eRuby, Apache can’t start up and writes the following to the error log: dyld: /usr/sbin/httpd Undefined symbols: \_rb\_cObject \_rb\_check\_type \_rb\_data\_object\_alloc \_rb\_define\_class\_under \_rb\_define\_method \_rb\_define\_module … So I’m guessing it’s trying to dynamically link to libruby and failing…or something…I have no idea what to do about that. Any ideas? I found quite a few postings with the same problem as this, but unfortunately couldn’t find any answers ☹ Thanks, Kevin ---

The following combination works fine for me: Mac OS X 10.3.2 (Panther) Ruby 1.8.1 Final (–enable-shared) Apache 2.0.48 mod\_ruby 1.1.1 (–with-apxs) eruby 1.0.4 (–enable-shared) Gennady. > **···** > > On Jan 19, 2004, at 20:40, Kevin M wrote: > > > I’m trying to get eRuby and mod\_ruby running on OS X (Panther). > > mod\_ruby seems to be working fine, but if I try to enable eRuby, > > Apache can’t start up and writes the following to the error log: > > > > dyld: /usr/sbin/httpd Undefined symbols: > > \_rb\_cObject > > \_rb\_check\_type > > \_rb\_data\_object\_alloc > > \_rb\_define\_class\_under > > \_rb\_define\_method > > \_rb\_define\_module > > … > > > > So I’m guessing it’s trying to dynamically link to libruby and > > failing…or something…I have no idea what to do about that.

Is there a reason you are using Apache 2 (as in, does it not work with the version that’s ditributed with OS X? I’d been trying with that). I had eRuby 1.0.5 and mod\_ruby 1.0.7 (same Ruby & OS X versions as you though). I tried reconfiguring everything with parameters as above, doing a make clean; make; make install, and now I get an error\_log message saying BUS ERROR instead, and Apache still won’t start. Perhaps I’ve made it worse 🙂 One last question though – will the ‘make install’ overwrite files as necessary, or might there be something left over I have to clean up manually? Sorry if these are dumb questions - I’m still a bit new to this 🙂 Cheers, Kevin ---

> mod\_ruby 1.1.1 (–with-apxs) Just to follow up: getting a newer mod\_ruby solved my problem. Thanks again… ---

I had eRuby 1.0.5 and mod\_ruby 1.0.7 (same > Ruby & OS X versions as you though). I was about to compile Apache anyway to include some specific options, so the choice for the latest version was merely because I wanted to stay with it as long as possible. > I tried reconfiguring everything with parameters as above, doing a > make clean; make; make install, and now I get an error\_log message > saying BUS ERROR instead, and Apache still won’t start. Perhaps I’ve > made it worse 🙂 You are almost there 😉 – BUS ERROR was exactly what I got with mod\_ruby 1.0.7 – version 1.1.1 (listed as development at the time I checked) has some serious fixes for that. I do not know if it matters or not, however I compiled everything ruby related with --prefix=/usr, as I noticed that some software (I do not remember what in particular) defaults to prefix /usr, while other to /usr/local on Mac OS X. > One last question though – will the ‘make install’ overwrite files as > necessary, or might there be something left over I have to clean up > manually? Sorry if these are dumb questions - I’m still a bit new to > this 🙂 ‘make install’ will overwrite files, however if some files are not used by a newer version, they will not be removed. So you may end up with some unnecessary garbage. That’s why I usually try to remove everything that I know of manually before running ‘make install’. > **···** > > > Cheers, > > Kevin
