Segmentation Fault in Snow Leopard

rubyonrails-talk
1

I just upgraded to snow leopard and I’m trying to get the 64 bit version

of mysql and ruby going. I ran through the steps here…

http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard/

mysql is running properly and when I run

which ruby I get…

/usr/local/bin/ruby

Which should be right. However, when I go to install rubygems…

sudo /usr/local/bin/ruby setup.rb

I get a segmentation fault. No matter what I try to do I get a

segmentation fault. My app was running just fine before the upgrade to

snow leopard and now none of my rake commands work, nothing but

segmentation faults. I’m stumped. Thanks in advance.

If you have Snow Leopard, then you should have following these instructions

to install Rubygems:

sudo gem update --system

Also, you can find further details here:

Good luck,

Thanks Conrad,

However, I also get a segmentation fault when I run

sudo gem update --system

Did you install the latest version of developer tools for Snow Leopard?

-Conrad

Yes,

I’ve got the snow leopard DVD. Went into optional installs and

installed Xcode.mpkg before I started any of this. Got a nice checkmark

saying it installed properly.

still getting segmentation faults with just about everything.

The lastest version of Developer Tools can be obtained from here if you’re

in the iPhone Developer Program:

http://developer.apple.com/iphone/

Otherwise, you’ll need to get the latest from here:

Xcode 3.2.1 Developer DVD (Disk Image)

Next, what the version of Ruby that you’re using? Also,

when you type gem -v, what appears on the screen?

Also, can you send the output of the following commands?

which gem

which ruby

Sure thing. Thank you. Seriously.

gem -v Illegal instruction (yikes)

which gem /usr/local/bin/gem

which ruby /usr/local/bin/ruby

OK, let's do the following for now:

1). Remove /use/local/bin from your       PATH.

2). Open a new shell window

3). Update Rubygems

       sudo gem update --system

4). Install Rails

       sudo gem install rails

Let me know what happen.

I ran

mate ~/.profile

It looked like this export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" I changed it to this export PATH="/usr/local/sbin:/usr/local/mysql/bin:$PATH"

I opened up a new shell and ran sudo gem update --system

Still got a segmentation fault.

After you make the above change, restart you OS? This should remove any of the resident libraries

from memory.

stripped the sbin part out...

Ran all the commands-

which gem /usr/local/bin/gem

gem -v Illegal instruction

which ruby /usr/local/bin/ruby

ruby -v Illegal instruction

echo $PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

(I also downloaded the latest iphone developer kit and installed it to be safe)

Did you use the Disk Utility app to “Repair Disk Permissions” on the system disk?

-Conrad

15

Yes!

Conrad…you are the man.

after a restart and the export path command, I was able to run

sudo gem update --system successfully

so now…

which gem

/usr/bin/gem

gem -v

1.3.5

which ruby

/usr/bin/ruby

ruby -v

ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]

This has been making my head spin all day. I really appreciate the

help. Are there any other commands I need to run to get everything

running smoothly in Snow Leopard?

This is great to hear. Also, make sure that you update your PATH

within your .profile to look exactly like the following:

export PATH=/usr/local/mysql/bin:${PATH}

The above statement is a very basic PATH and it should be sufficient

for now. Also, I would recommend installing the following gems if

you haven’t done so already:

sudo gem install rails

sudo gem install sqlite3-ruby

sudo env ARCHFLAGS=“-arch x86_64” gem install mysql – --with-mysql-config=/usr/local/mysql/bin/mysql_config

sudo gem install mongrel

sudo gem install gemcutter

gem tumble

Note: The above assumes that you followed the MySQL installation instructions here:

   [http://weblog.rubyonrails.org/2009/8/30/upgrading-to-snow-leopard](http://weblog.rubyonrails.org/2009/8/30/upgrading-to-snow-leopard)

Last but not least, there are many gems and the primary gem host is located at http://www.gemcutter.org.

Good luck,

I ran those commands and I thought everything was installed properly, but I'm still having a mysql issue. I ran one of my rake commands for my app and got...

!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! no such file to load -- mysql

and then ran gem install mysql but got this...

Any idea what is wrong with mysql?

Maybe the C headers are not installed/discoverable? How did you install mysql? I've found that the 10.5 64 bit package hosted on the mysql site makes things easier than installing from source.

Also, you're going to need to specify 64 bit when you install the mysql gem:

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql- config=/usr/local/mysql/bin/mysql_config

18

Oh. Just went back and read the rest of the posts.

You may want to re-install mysql. If you installed xcode, then installed mysql, then installed xcode again, the mysql system libraries may have been crushed in the last xcode install. Just a guess.

19

Think of it as a learning experience :slight_smile: Some people pay for this kind of training.

What kind of computer is this? If you run this in a terminal window:

ruby -e "p ['foo'].pack('p').size"

Do you get 4 or 8? Ruby should be running in 64 bit mode (thus giving you an 8).

Also, how did you install mysql? Did you install it using port or fink? Did you install from a package?

20

I get an 8. I seem to be going in circles unfortunately.

If I run this command...

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Things get messed and I get segmentation faults on my rake commands and Illegal instruction on commands like gem -v or ruby -v.

If I go back and run export path commands

PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

this gets rid of the illegal instruction errors.

As far as mysql goes, first time around I followed these instructions

did everything in the shell

2nd time around after talking to you, I followed this instructions and did it through a package

However, I'm missing a step in the sequence of things I need to do to get this right and it either results in a segmentation fault or that last error I posted "lazy symbol binding failed."

I'm just lost now going in circles. Either of you guys have 5 minutes for an IM convo today? Just run through the commands real quick see if we can get it going?
