Installing MySQL gem on Mac Leopard

December 30, 2008

If you are getting following error on trying to install mysql gem on mac (Leopard, in my case)

$ sudo gem install mysql
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:
ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb install mysql checking for mysql_query() in -lmysqlclient... no checking for main() in -lm... yes checking for mysql_query() in -lmysqlclient... no checking for main() in -lz... yes checking for mysql_query() in -lmysqlclient... no checking for main() in -lsocket... no checking for mysql_query() in -lmysqlclient... no checking for main() in -lnsl... no checking for mysql_query() in -lmysqlclient... no extconf.rb failed Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.  Check the mkmf.log file for more details.  You may need configuration options.

Try following

$ sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions.  This could take a while...
Successfully installed mysql-2.7
1 gem installed

The above thing is correct only if you have installed 32 bit MySQL dmg. If you have installed 64 bit MySQL dmg, you are sure to get following error on running rails server or any ruby app using mysql gem

dyld: lazy symbol binding failed: Symbol not found: _mysql_init
  Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle
  Expected in: dynamic lookup

dyld: Symbol not found: _mysql_init Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.7/lib/mysql.bundle Expected in: dynamic lookup

Trace/BPT trap

The reason is that MySQL Ruby gem build is 32 bit one and it doesn’t work well with 64 bit MySQL dmg

To solve all this, uninstall installed 64 bit MySQL dmg as follows ( There is no good way to uninstall MySQL from Mac other than below)

 sudo rm /usr/local/mysql
 sudo rm -rf /usr/local/mysql*
 sudo rm -rf /Library/StartupItems/MySQLCOM
 sudo rm -rf /Library/PreferencePanes/My*
 edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
 sudo rm -rf /Library/Receipts/mysql*
 sudo rm -rf /Library/Receipts/MySQL*

Now download and install 32 bit MySQL dmg

"You know you are a true Rahman fan when..."

December 07, 2008
  1. You have a peculiar taste in music, which does not necessarily have to match the taste of the “masses”.

  2. You have a good sense of melody and rhythm and can tell good music from average. You appreciate good music, regardless of who it comes from.

  3. You can go on for hours talking about Rahman when someone makes a mistake of asking you about your favorite music.

  4. You are never content and are always hungry and thirsty for more from Rahman.

  5. You have had many euphoric moments in your life.. connected with Rahman’s music.

  6. You agree that an average Rahman song is better than the best most of the other can churn out.

  7. Regardless of how the World finds Rahman music, you think Rahman makes music just for your ears. You genuinely believe that Rahman somehow knows what kind of music you unconsciously crave and then magically delivers that to you.

  8. Your most prized collection in your entire music collection is your Rahman collection, whether it’s in form of cassettes, CD’s or hard-disk space on computer or ipods.

  9. You sometimes feel this bliss, a kind of feeling that you are in heaven, when listening to Rahman’s music.

  10. If the World was to go back to using the barter system again, you wouldn’t mind trading a 1000 non-Rahman songs for a single Rahman song.

  11. You share this special bond with Rahman which is impossible to describe in words, let alone explain it to others.

  12. Your friends/family fail to understand why you listen to music in a language that makes no sense to you, whatsoever. But, a few weeks later, you totally understand why your friends/family are humming/singing the very song they don’t understand and were puzzled about you listening to it.

  13. You are part of the Rahman Yahoo! Group or Orkut A R Rahman fans Community and visit it at least once a day.

  14. You take pleasure in new group (community) members arguing with likes of Gops and Vijay, when they come out with some Rahman info/news.

  15. You are tired of new member joining the group and inquiring about and referring to the fake “Ekyam Satyam”. You too hope to listen to the real one someday, if it exists somewhere.

  16. You can talk to any other Rahman fan and connect with them instantly.

  17. You have a deep desire to meet Rahman in person, and know deep in your heart that one day your dream will come true.

  18. You have thought of it many a times and tried to come up with a plan of what you would do? How would you react? when you actually meet Rahman.

  19. You can find the challenging task of solving a complex problem rather easy compared to the daunting and difficult task of coming up with your absolute top-10 Rahman favorites.

  20. Any criticism of Rahman is hard for you to digest, because most of the time it comes from people that haven’t heard enough of Rahman and yet have no problem talking about him.

  21. Your blood pressure tends to rise when an average listener sings praises for other MDs(especially Anu Malik, Harris J, and the more recent and annoying Himesh).

  22. When it comes to R.D. Burman or may be Illayaraja, you tend to put an end to the conversation by saying… “No doubt, Illayaraja is the greatest, but I think Rahman is even better”… because it’s true. (Self-fulfilling prophecy?)

  23. You are a select few in the country that are familiar with obscure terms such as “BGM” or “Interlude” etc. And furthermore, you are a rare breed of fans that actually collects and listens to these “BGM” and “Musical bits” used in commercials.

  24. You can listen to an hour of non-stop Rahman interludes and guess over 80% of them right.

  25. You eagerly wait for each and every Rahman release, you set very high expectations for each album, a day after the release you will bash the album as below-average, a few months later you will hail the same album as a masterpiece and one of your personal favorites.

  26. You suffer from this rare condition where… you wake up from your sleep, humming or singing a Rahman tune, involuntarily. You realize the condition is severe when you randomly shout out a Rahman tune you haven’t heard in a long time.

  27. You may forget to take your dose of medication but you can not forget to get your daily dose of Rahman.

  28. You set high expectations of Rahman, and are honored and touched that he cares about you and works hard to satisfy you.

  29. You know and realize that Rahman is potentially the most creative composer to ever live in India, and may be even the World.

  30. You love and respect Rahman, the human being and not just Rahman, the composer.
