Problem installing mysql gem

Rails
1

Hi guys,

I’m totally new in ruby. I’d appreciate some help.

I followed the Getting Started guide in www.rubyonrails.org, and got
the server up and running on a sample app I’ve created, as the guide
perscribed.

Now I’m stuck with the installation of mysql gem.

I’ve tried "gem install mysql – --with-mysql-config=“c:\Program Files
\MySQL\MySQL Server 5.0\scripts\mysql_config”.
All I got was:

Successfully installed mysql-2.7.3-x86-mswin32
1 gem installed
Installing ri documentation for mysql-2.7.3-x86-mswin32…
Installing RDoc documentation for mysql-2.7.3-x86-mswin32…
ERROR: While generating documentation for mysql-2.7.3-x86-mswin32

x86-mswin32/rdoc --exclude ext --main README --qu
iet ext README docs/README.html
(continuing with the rest of the installation)

I’ve downloading the api by my self and install it, but it keeps
failing on:

have_library: checking for main() in libmysql.lib…

Anybody can help here??

Did you try

gem install mysql – --with-mysql-config=“c:\Program Files\MySQL\MySQL
Server 5.0\scripts\mysql_config” --no-rdoc --no-ri

Looks like its the doc generation thats failing…

I’m also having the same problem. Tried that ant it still doesn’t work.

In addition, I’m getting this when trying to run in rails:

The specified module could not be found. -
c:/ruby/lib/ruby/gems/1.8/gems/mysql-2.7.3-x86-mswin32/ext/mysql.so

Try installing MySQL in a directory without any spaces, e.g., c:
\mysql5.
And then try installing the mysql gem.

Ok… found the solution. At least for me.

remove the
RUBY_HOME\lib\ruby\gems\1.8\gems\mysql-2.7.3-x86-mswin32\ext\mysql.so
and everything will work again.

Also, some people noticed that this files is also on
RUBY_HOME\lib\ruby\site_ruby\1.8\i386-msvcrt

Removing or renaming this file fix the problem as suggested on this

Thanks anyway. =)
