I'm trying to move a small Sinatra app I have going on an Ubuntu box to a redhat box.
While installing gems, I get a "Can't build native extension" error while trying to install the gem dm-mysql-adapter.
I have mysql-devel installed, which I believe is the required library, but it doesn't seem to work.
All the info I can find online is for Ubuntu and says installing libmysqlclient-dev (which doesn't exist for Redhat; again, I believe mysql-devel is the appropriate package).
Any advice for someone using redhat?
you have the correct package "mysql-devel-5.1.48-1" but the gem installs fine on my centos5 box without the package installed, you could try the ruby-mysql gem instead.

I ma trying to install fat free crm on windows using these instructions http://guides.fatfreecrm.com/Setup-Microsoft-Windows.html
I am on the part where we install mysql2 lib and libmysql.dll
The command "gem install --no-rdoc --no-ri mysql2 -v 0.2.7 -- with-mysql-dir=X: --with-mysql-lib=X:\bin --with-mysql-include=X:\include" fails and error comes "Error installing mysql2:
ERROR: Failed to build gem native extension.".I fixed this part my changing the version of mysql in the command to 0.3.11.Now the last step says to copy libmysql.dll but I cant find that file in the specified directory.
If it's of interest, Bitnami has recently published a one-click installer for FFCRM. See https://bitnami.com/stack/fat-free-crm I'll also update the FFCRM docs to note this.
I've recently started exploring JRuby using Joe Kutner's book "Deploying with JRuby", but I've hit an issue when trying to install the jruby-lint gem. Below is the output from my attempts, including the version numbers of Java, JRuby, and my OS.
I don't understand the output, especially why nokogiri wouldn't install as a jruby-lint dependency, but would install ok on its own. While the jruby-lint gem is now reported as having installed correctly, it has not delivered a jrlint executable/script to use, and I don't know where to go from here. Any ideas?

I ran into a very similar issue, also while working through this book. Updating Rubygems solved it for me. Perhaps try:
jruby -S gem update --system
It's interesting that it tries to install the Ruby(not JRuby) version of Nokogiri cause it tries to install C extensions.
I think if you install the same version required by jruby-lint which is nokogiri-1.6.0.rc1, problem will be solved.
Neither solution here works for me on Windows. jruby -S gem install nokogiri
installs nokogiri-1.6.0-java
If I download the gem from https://github.com/jruby/jruby-lint and build it myself it leaves the gem folder empty at jruby\lib\ruby\gems\shared\gems\jruby-lint-0.4.1
And it won't make a bat file for running it in the /bin dir. I don't think this gem is ready for windows. Could it be that I'm trying to install it on BitNami stack? I haven't tried it with a regular install of JRuby.
In case updating Rubygems doesn't work, try:
gem install nokogiri
This will install nokogiri-1.6.0-java
then again:
gem install jruby-lint
and you're good to go.
Environment:
Windows 7 64bit (Home Premium)
Ruby 1.9.2 p290 (2011-07-09) [i386-mingw32]
Rails 3.0.10
MySQL 5.5
Ruby, despite my having successfully installed the mysql2 rubygem thinks that the gem is missing when I invoke a rails command that requires it.
After having spent the evening getting the mysql rubygem installed on Windows 64 bit, I decided to (finally) get cracking on linking mysql to a local rails server. This is how I was trying to do it...
(Fairly) Exact transcript from cmd.exe

Notes:
I noticed it wants rubygem mysql2-0.2.11, I have 0.3.7. I tried installing 0.2.11 specifically by the method I used to install the two gems above. No dice, it couldn't find a gem by the name mysql2-0.2.11 in 'any repository'
I'm stumped, any thoughts fellas (and gals)?
I believe your MySQL installation is a 64bits (like Windows), correct?
Ruby is 32bits, so you cannot link 32bits against 64bits.
I've posted a article covering the installation steps on my blog:
http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/
These steps use MySQL Connector/C to workaround the 32bits versus 64bits issues.
Both mysql or mysql2 gem should work with this.
Have you included mysql2 in your Gemfile and subsequently executed bundle install ?
## my sql installation (on 64 bit architecture)
download connector (download zip file and extract it to c drive)
http://dev.mysql.com/downloads/connector/c/
download mysql
http://dev.mysql.com/downloads/installer/5.6.html
command to install mysql with connector
C:\Sites\rails_project\resume>gem install mysql --platform=ruby -- --with-mysql-
dir=C:/mysql-connector-c-6.1.0-win32
After this copy libmysql.dll from connector folder and paste it to ruby>bin folder
Ruby already installed on Mac. So i just installed rails.

Dont understand what to do. gem install mysql installing without MySQl itself or I should download and install MySQL as prorgamm? If yes, from what resource, what version, how to instal? Please help me, im newbie on mac. Big thanks!
You're almost certainly going to need MySQL installed to have the MySQL gem installed (even better is the mysql2 gem, which Rails also works with - just use mysql2 instead of mysql in your database.yml file).
I find the best way to get MySQL on my Mac whenever I format it (which, admittedly, is rarely) is to use Homebrew. So, if you don't have Homebrew installed, I'd start with that... and once that's done, it should be a matter of running sudo brew install mysql, and running the instructions it provides after the installation is done.
So I am getting the same issue as mentioned here -
gem install mysql failure in Snow Leopard
But I haven't been able to get it fixed using the answers on this link.
Here's a brief history -
I had MAMP on my machine,
but now I downloaded the latest MySQL from mysql.com and installed version 5.1.46
this new version runs fine and client "mysql" is able to connect
and I also have XCode v3.2.1, since someone mentioned that it can cause issues.
Here's the error -

"can't find header files for ruby" usually means that the system can't locate the header files for Ruby. This happened to me when I upgraded to 10.6 from 10.5. Download the latest XCode from Apple's site and reinstall it. Make sure that you check the box for "UNIX Development" during the install. The header files for Ruby are not in the main package.
Have you installed other versions of Ruby or are you using the standard 1.8.7 that comes with OS X? You can check your version of ruby by typing ruby -v at a terminal prompt.
