How To: Install FreeTDS and UnixODBC On OSX Using Homebrew For Use With Ruby, Php, And Perl

jared.folkins — Tue, 10 Jan 2012 17:44:52 +0000

This little project started out as a basic script to connect to a Microsoft SqlServer and get data. It was a nightmare as I probably spent 15 hours learning about and troubleshooting both FreeTDS and UnixODBC. My pain is now your gain.

NOTICE: I have homebrew configured to install all packages into my local directory /Users/jared/.homebrew/

1) Install UnixODBC

[jared@localhost]$ brew install unixodbc
==> Downloading http://www.unixodbc.org/unixODBC-2.3.0.tar.gz
File already downloaded in /Users/jared/Library/Caches/Homebrew
==> ./configure --disable-debug --prefix=/Users/jared/.homebrew/Cellar/unixodbc/2.3.0 --enable-gui=no
==> make install
/Users/jared/.homebrew/Cellar/unixodbc/2.3.0: 24 files, 932K, built in 22 seconds
[jared@localhost]$

2) Edit the FreeTDS formula And install

What we are doing is changing the default tds version, enabling the msdblib, and pointing out where unixodbc installed.

require 'formula'
 
class Freetds > Formula
url 'http://ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-0.91.tar.gz'
homepage 'http://www.freetds.org/'
md5 'b14db5823980a32f0643d1a84d3ec3ad'
 
def install
system "./configure",·
"--prefix=#{prefix}",·
"--with-tdsver=7.0",·
"--enable-msdblib",
"--with-unixodbc=/Users/USERNAME/.homebrew/Cellar/unixodbc/2.3.0",
"--mandir=#{man}"
system 'make'
ENV.j1 # Or fails to install on multi-core machines
system 'make install'
end
end

[jared@localhost]$ brew install freetds

3) Start a new terminal session to make sure all your paths update

4) Confirm that you can connect to the server

We need to make sure that you can connect to the sqlserver and that the port is open and available to you.

To do this we use telnet. If you see the following, success! The port is open on the server.

[jared@localhost]$ telnet server.example.com 1433
Trying 192.168.1.101...
Connected to server.example.com.
Escape character is '^]'.

If you see the following. You failed. Check the Sqlserver configuration, firewalls, or network configuration.

[jared@localhost]$ telnet server.example.com 1433
Trying 192.168.1.101...
telnet: connect to address 192.168.1.101: Connection refused
telnet: Unable to connect to remote host

Note: Press the ctrl + ] keys to break to a prompt and then type exit.

5) Tsql

FreeTDS comes with a couple cli applications. One of them is tsql. It isn’t great, but I use it test and see if at least FreeTDS is working correctly. After you install FreeTDS using homebrew try and connect to the host using the following command.

[jared@localhost]$ tsql -H server.example.com -U USERNAME -P PASSWORD -v
 
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
1>exit

If you see a prompt, you haz awesome!

6) Sym link the FreeTDS and UnixODBC conf files

I create 3 sym links to the following files just for simplicity.

ln -s /Users/jared/.homebrew/Cellar/freetds/0.91/etc/freetds.conf ~/.freetds.conf
ln -s /Users/jared/.homebrew/Cellar/unixodbc/2.3.0/etc/odbc.ini ~/.odbc.ini
ln -s /Users/jared/.homebrew/Cellar/unixodbc/2.3.0/etc/odbcinst.ini ~/.odbcinst.ini

7) edit the .freetds.conf and add the following

[example]
host = server.example.com
port = 1433
tds version = 7.0

8 ) edit the odbcinst.ini and add the following

You are telling unixodbc where your FreeTDS drivers are located using this configuration file.

[FreeTDS]
Description = FreeTDS
Driver = /Users/jared/.homebrew/lib/libtdsodbc.so
Setup = /Users/jared/.homebrew/lib/libtdsodbc.so
UsageCount = 1

9) edit the .odbc.ini and add the following

[myexample]
Driver = FreeTDS // we just set this up a second ago
Description = MyExample
ServerName = example // this is the name of the configuration we used in the .freetds.conf file
UID = USERNAME
PWD = PASSWORD

10) isql should work

[jared@localhost]$ isql sqlinternal USERNAME PASSWORD
+---------------------------------------+
| Connected!
| sql-statement
| help [tablename]
| quit
+---------------------------------------+
SQL>quit

11) Osql Error

If you try osql, it throws an error.

[jared@localhost]$ osql -S myexample -U USERNAME -P PASSWORD
checking shared odbc libraries linked to isql for default directories...
/Users/jared/.homebrew/bin/osql: line 53: ldd: command not found
strings: can't open file: (No such file or directory)
osql: problem: no potential directory strings in "/Users/jared/.homebrew/bin/isql"
osql: advice: use "osql -I DIR" where DIR unixODBC\'s install prefix e.g. /usr/local
isql strings are:

reading /Users/jared/.odbc.ini

looking for entry named [FreeTDS] in /odbcinst.ini
found driver line: " Driver = /Users/jared/.homebrew/lib/libtdsodbc.so"
found driver /Users/jared/.homebrew/lib/libtdsodbc.so for [FreeTDS] in odbcinst.ini
/Users/jared/.homebrew/lib/libtdsodbc.so is not an executable file
osql: error: no driver found for sqlinternal
[jared@localhost]$

If you go through the error you will find that a certain driver is not executable. You just need to chmod the file.

[jared@localhost]$ chmod 554 /Users/jared/.homebrew/Cellar/freetds/0.91/lib/libtdsodbc.0.so

Now run it again.

[jared@localhost]$ osql -S myexample -U USERNAME -P PASSWORD

/Users/jared/.homebrew/bin/osql: line 53: ldd: command not found

Configuration looks OK. Connection details:

Driver: /Users/jared/.homebrew/lib/libtdsodbc.so
Server hostname: myexample.bendcable.net

How To: Install The HomeBrew Package Management Utility Locally On Mac OSX

jared.folkins — Mon, 29 Aug 2011 18:20:30 +0000

I was tired of having to compile my shiz by hand and not being a fan of Macports, I decided to give HomeBrew a try. Not knowing if I would like it, I wanted to install it locally in my home directory so that I could blow it away should it upset me.

Here are the steps I used to make it happen.

Assuming that you have git and all other dependancies (Intel CPU 2, OS X 10.5 or higher, Xcode with X11 3, Java Developer Update 4) installed.

jared@localhost$ cd

jared@localhost$ git clone https://github.com/mxcl/homebrew.git

jared@localhost$ vi ~/.bash_profile

Add the following line then :wq

export PATH=$HOME/homebrew/bin:$PATH

Open a new shell session and type brew.

jared@localhost$ brew
Example usage:
  brew install FORMULA...
  brew uninstall FORMULA...
  brew search [foo]
  brew list [FORMULA...]
  brew update
  brew upgrade [FORMULA...]
  brew [info | home] [FORMULA...]
 
Troubleshooting:
  brew doctor
  brew install -vd FORMULA
  brew [--env | --config]
 
Brewing:
  brew create [URL [--no-fetch]]
  brew edit [FORMULA...]
  open https://github.com/mxcl/homebrew/wiki/Formula-Cookbook
 
Further help:
  man brew
  brew home

You are all set!

Macifier - Pacifying Your Keyboard And Mouse

My daughter Gracie was routinely disabling our family laptop while she skyped with her Grandparents. So I wrote a small Macintosh application that locks the keyboard and mouse. After showing the initial app to my buddy Mike Brisk, he created an awesome logo.

(Nerd) Logitec MX Mouse & Snow Leopard 10.6 functionality

jared.folkins — Tue, 01 Sep 2009 18:04:35 +0000

For hard core geeks out there, nothing is more important than peripherals. Having a solid setup makes life a lot easier when your livelihood is working on the computer day in and day out.

Keyboard = link

Mouse = link

Recently we have been testing the new and (Not Really) improved Mac operating system. I use my mouse to bounce in between virtual desktops by assigning several of my mouse buttons to the applications ‘Spaces.app’ and ‘Expose.app’. After upgrading to 10.6 (Snow Leopard) those features ended up broken. The reason is that Snow Leopard moved the applications ‘Spaces.app’ and ‘Expose.app’ into the ‘Utilities’ directory. The good news is that the fix is simple, all you have to to is create a couple of Symbolic links.

This is assuming you have the Logitech software installed for the mac.

1) Open the application ‘Terminal’

2) From the command line, run the following commands. You may be prompted for your password.

sudo ln -s /Applications/Utilities/Spaces.app /Applications/Spaces.app

sudo ln -s /Applications/Utilities/Expose.app /Applications/Expose.app

And that should do it!

You may need to reassign your mouse buttons again in;
‘System Preferences’->’Logitech Control Center’
