[MacRuby-devel] mysql gem fails to install

[Jean-Denis MUYS]

Hello again,

One of the gem I use is mysql. It used to work. I still have forensic evidence of that in the older place where gems were installed (deep within /Library/Frameworks).

Now it doesn't install. Here is the full terminal transcript:

Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

Results logged to /Library/Ruby/Gems/MacRuby/0.12/gems/mysql-2.8.1/ext/mysql_api/gem_make.out

I checked the mkmf.log for more info. Here is its full content:

have_func: checking for mysql_ssl_set()... -------------------- yes

I tried to execute the call to gcc-4.2 in there. gcc replies "no input files".

the mkmf.rb file mentioned is a MacRuby file and the gem installs fine using the regular "gem" command, so I suspect the problem is MacRuby's (especially since I had installed no so long ago), but I am not enough of a rubyist to go further.

Any suggestion?

Thanks,

Jean-Denis
