Just a few days ago, I had the opportunity to upgrade my iMac from a 20” to a 24”. Not only does it have more real estate on the screen, not only is the CPU slightly faster, but it also can take up to 3 Gb of RAM, from 2Gb, which is quite an improvement, especially if you like to run multiple VMs (using Parallel).

So it was quite a relief to us my notes to install Rails on Mac OS Tiger. Except that a lot has changed in the past 3 months since I last wrote that article, and before I update the page to make more sense to newcomers, I’ll just write down a few notes on what I had to do differently.

These reflect the installation on MacOS 10.4.8 and the latest version of MacPorts (as of 10/14/06).

First of all, Darwin Ports is no more: long live MacPorts!

Which means that here is a new location for darwin ports installer.

Then I uncovered a problem in the order of the steps:

Set the PATH before running “sudo port -d selfupdate”, not after as suggested.

One thing that I did not realize, is that you need to actually install a C compiler before you can get started! The easiest is to install XCode 2.4. There is a free registration you need to fill in.

I missed a sudo:

cp httpd.conf.sample httpd.conf => sudo cp httpd.conf.sample httpd.conf

The path to the launchctl file for apache2 has changed:

sudo launchctl load -w /Library/LaunchDaemons/org.macports.apache2.plist instead of sudo launchctl load -w /Library/LaunchDaemons/org.darwinports.apache2.plist

To initialize the database, you need to add:

add "sudo -u mysql mysql_install_db5"

The path to the launchctl file for mysql5 has changed as well:

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist instead of sudo launchctl load -w /Library/LaunchDaemons/org.darwinports.mysql5.plist

replace rb-mysql5 with rb-mysql since rb-mysql supports both flavors

And that’s where it got a bit tricky. With that combination of MacOS 10.4.8 and the current version of MacPorts, rb-mysql fails to compile.

make: *** [mysql.o] Error 1

At this point your are either stuck waiting for an update version, or if you are not afraid to dip into the code, you can arm-twist it into working by following these steps:

rb-mysql patch

These steps should be fairly simple to follow:

cd /opt/local/var/db/dports/build/_opt_local_var_db_dports_sources_rsync.rsync.darwinports.org_dpupdate_dports_ruby_rb-mysql/work/mysql-ruby-2.7.1
sudo ruby extconf.rb --with-mysql-include=/opt/local/include/mysql5/mysql/ --with-mysql-lib=/opt/local/lib/mysql5/mysql/

add '#include "my_global.h"' to mysql.c (as the first #include)
sudo make clean
sudo make
sudo make install

And voila. Running the tests will show 3 failing tests, mostly due to imprecisions, but I think you can live with them. Further testing with rails apps did not reveal any problems with MySQL access.

Note: I’ve contacted the maintainer of that port but I have not heard back yet. I will update this post when I do.

A few bonus gems I’ve found helpful, or can’t live without

And since you are in setup mode, you might as well add them to your collection.

If you think hooking your ride up with an in-car PC is 1337, or if you were impressed with Samsung's lineup of LED-backlit LCDs earlier today, you'll probably admire this one as well. For reasons unknown to mere men, a crafty car modder set out to not only install a water-cooled LED-backlit LCD into his ride, but to actually construct it. Taking a 12.1-inch widescreen display, he replaced the CCFL lamp with no fewer than 32 one-watt Luxeon LEDs, resulting in brightness akin to staring at the world's largest star. Additionally, he utilized a liquid-cooling setup which he later stated wasn't entirely necessary, but it does give you one more reason to boast. While we highly doubt the novice DIY crowd should try to replicate this without tons of dough and time to waste, be sure to click on through for a few more works-in-progress shots, or hit the read link for the full skinny.

Let's get one thing straight on this right from the start: this methodology makes little sense if you've got exactly one machine to install Vista on, as you'll probably spend more time making your USB flash drive bootable than it'd actually take to get your single machine up and running. So, to those of you who are staring down that daunting line of machines that you're fully responsible for, and can't imagine pulling yet another 18-hour day just to get Vista on every single one, here's a way to cut out early without being reprimanded. Joining the list of other high-profile applications that are better booted from a flash drive than CD / DVD or external hard drive, Windows Vista has now been figured out, and the process looks to be relatively painless; just snag a 4GB (or so) high-speed flash drive, format it, and copy Vista's DVD-ROM content over. Of course, you want to be real sure you get all the command lines right, so if you're seriously pondering doing this yourself, do yourself a favor and hit the read link for the expert's take, and watch each successive installation go from 20-minutes or more to "around 5 to 10" -- and leave it in your machine when you're finished for a bit of that ReadyBoost advantage, cool?

I've been noticing that quite a few of you are having issues uninstalling a framework when partially installed or when it has been corrupted.

If you can get to the framework origininal installation package then that would be very helpful. A central location to get these downloads would be: http://msdn2.microsoft.com/en-us/netframework/aa569263.aspx

Then after you've got the installation package on your machine, execute it.  what happens is that the installation will go into what is known as the maintenance mode.  It will give  you the option to repair and uninstall the framework.

Repairing and then uninstalling the framework in this manner normally will fix most of the issues that we've seend. 

For those of you who are using 3.0, we've released a 3.0 prerelease clean up tool, which should help you put your machine into a clean state.

http://www.microsoft.com/downloads/details.aspx?familyid=AAE7FC63-D405-4E13-909F-E85AA9E66146&displaylang=en  

 

Share Tag It! read more...

Commonly this is caused by the installation program you've downloaded to become corrupted in the download. By redownloading to either a different location you should be able to fix this issue.

 Another common remedy for this issue is to download the redistributable package corresponding to your architecture:

To download the full redistributable package, rather than the bootstrapper, click the architecture you need below to start the download:

X86 Redist Package

X64 Redist Package

The redistributable might download more than you need, but is a single download.  This is a preferred method if you do not worry about bandwidth, or if you want to put it on a secure location.

Be sure to Check Windows Update for any updates after you've installed the .NET Framework.

Most of the time this issue points back to a corrupted download.  Redowndownloading the package to a different directory will normally do the trick.

The place to download the framework from:

http://msdn2.microsoft.com/en-us/netframework/aa731542.aspx

You will need to make sure that you download the right architecture that matches your machine.
