C compiler cannot create executables

You need to install some development tools that are not installed by default. This should help:

sudo apt-get install build-essential

Thank you for your help. But when i try to continute to install. the message is like following, it seem like 'mkdir' permission denied

mkdir -p -m 755 /usr/local/lib/ruby/1.8 /usr/local/lib/ruby/1.8/i686-linux /usr/local/lib/ruby/site_ruby/1.8 /usr/local/lib/ruby/site_ruby/1.8/i686-linux

Are you using sudo before ./configure && make && make install?

From the above message, it seems that your make was successful, but make install failed, because you don't have write permissions for /usr/local/

By the way, if you are using Feisty, and want to install ruby 1.8.5 through apt-get, do sudo apt-get ruby1.8
Doing sudo apt-get ruby will install ruby 1.8.2-1, and doing sudo apt-get ruby1.9 will install ruby 1.9

Yes. I use command like following:
sudo ./configure && make && make install.

Still give me the wrong message. i am installing ruby 1.8.4. do you mean try sudo apt-get install ruby1.8. it is not working. How do i solve the write permissions for /us/local/ ??? it is still same erro after running?.

Thanks a lot!!!

Hello,
If you want to install ruby on ubuntu, the easiest method is to use a precompiled package, try:
sudo apt-get install ruby

If you really want to compile ruby from source, then the correct command is:
./configure && make && sudo make install

sudo apt-get install ruby works fine !!! Thanks a lot !!! One question,

when I type ruby -v, it shows: ruby 1.8.4 (2005-12-24) [i486-linux]

I guess that's mean ruby already install ??

Yup, you have ruby installed now :-)

Thank You!!!!!

What commands for install : RubyGems and Rail ??? Please help. i need to get this done

In fact, this is my first time using Linux. I just follow the book to install. But Can not be sucessful until you guys direct me.

For installing Ruby on Rails and RubyGems, use this:
sudo apt-get install rails rubygems

Here are the package details:
http://packages.ubuntu.com/feisty/web/rails
http://packages.ubuntu.com/feisty/interpreters/rubygems

Sorry, it still shows some mistakes

:~/Desktop$ sudo apt-get install rails rubygems
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package rails

Also, for some reason, even though i have ruby install, why i can not find any directory and file for ruby 1.8.4

Thanks a lot!!

Hello,

to install rails, you have to add the universe repository,
howto here: https://help.ubuntu.com/community/Repositories/Ubuntu#head-5bbef89639d9a7d93fe38f6356dc17847d373096

hmm in fact this howto is not really up-to-date,

you can add the universe repository with:
System->Administration->Software sources

And if you want to know which files are installed for the ruby package,
go to synaptic: System->Administration->Synaptic Package Manager
Search for ruby
right-click on ruby -> Properties
Go to 'installed Files' tab

I try to use following link to install rubygems:
http://packages.ubuntu.com/feisty/interpreters/rubygems

it gave me message "Error:Dependency is not satisfiable : libgems-ruby1.8

Also, when itry to command:sudo apt-get install rails rubygems

E: Couldn't find package rubygems

FYI:I already add universe repository

Thank for your help !!!

Hello,

What is the result of this command ? :
sudo apt-cache madison libgems-ruby1.8 rubygems

Does running "sudo apt-get update" solve this ?

What is the content of /etc/apt/sources.list file ? :
cat /etc/apt/sources.list

after run : sudo apt-cache madison libgems-ruby1.8 rubygems .
I still have the same problem: E: Couldn't find package rubygems

After run "sudo apt-get update" , The erro message is below:

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

i tired to cat sources.lst. no such directory. I used synaptic package manage found there is no cotents in source.lst but in source:

You made a typo, it is "cat /etc/apt.sources.list" NOT "cat /source.lst"

about the error with sudo apt-get update, it means that a update program is open and is blocking access to other update programs, closing the update program or rebooting the computer should fix this problem.

Ok. I will try that soon and will let you know about it.

By the way, what is command for install MYsql database.

could you give me the steps for downlaon ruby,rails, rubygems and mySQl. I saw some sites have by click one to download for whole package. I don't know know if there is one click to donwload everything for Linux. Please give me the steps.

still not work. Can somebody help to install that thing !!! i was so painful.

Right now . I ma try to install ubygems. after i run ruby setup.rb
give me the erro:

/usr/local/lib/ruby/site_ruby/1.8/rubygems/remote_fetcher.rb:4:in `require': no such file to load -- zlib (LoadError)
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems/remote_fetcher.rb:4

        from setup.rb:814:in `invoke'
        from setup.rb:773:in `invoke'
        from setup.rb:1578

Please help. I don't understand why just install this to Linux are so difficult???

Hello again,

You still didn't answer my question, what is the content of the /etc/apt/sources.list file ?
please type the following in a terminal (without errors) and report the output here:
cat /etc/apt/sources.list

PLEASE SEE BELOW REPORT:

ahhhhhhh

You should have told us you are still using ubuntu edgy.
Please upgrade to feisty.
more information here:
http://www.ubuntu.com/getubuntu/upgrading

Taje so long to upgrade. what's wrong with this software. i almost given up. Would you just tell how to uninstalll the linx. I don't want to install anymore. I feel really sad. so many mistakes. i could not figure out. I know i am using the old version. however, why it is so many problems.....I could not understand !!! i also try to donwload 7.04 v to my live cd. It takes so long to download (15% only but already 4 hours)

But thank you for your help !!!

one question:

do i have to download 7.04 desktop eidition or server edition ? i need to post my site in public

Thanks

The desktop edition automatically installs a graphical desktop (gnome for ubuntu, kde for kubuntu, xfce for xubuntu). The server edition does not, but instead installs automatically some server software (i.e. webserver, database etc.)

In general you can start with either edition since you can always install all software later. However, it makes sense to use the one that is from the beginning closer to what you want to do.

if i want to install ruby on rails. so i need to install server edidtion or desktop edition. Please advise

thanks

when i trird to run :sudo apt-get install ruby ri rdoc libmysql-ruby

E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

Thanks for your question.

Please close Synaptic Package Manager before calling that command.

You can install ruby on rails on the server edition as well as the desktop edition. Since, the desktop edition automatically installs a graphical desktop, I'd recommend desktop edition for you. (though you can also install a graphical desktop on server edition as well).
