buildr(1)Introduce and Install

1. Install on Linux
>wget http://buildr.apache.org/scripts/install-linux.sh
>sudo sh install-linux.sh

It told me that I need these things as follow:
No package ruby available.
No package rubygems available.
No package ruby-devel available.
No package gcc available.

Hard to believe that. So many things to do on redhat.

message:
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
No package httpd-devel available.
Nothing to do

solution:
>vi /etc/yum.conf
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

[base]
name=CentOS-$releasever – Base
baseurl=http://mirror.centos.org/centos/4/os/x86_64/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever – Updates
baseurl=http://mirror.centos.org/centos/4/os/x86_64/
gpgcheck=1

>sudo yum clean all
>sudo yum update --skip-broken

Install gcc, git on my system.
>sudo yum install glibc-kernheaders --skip-broken

Some cycle dependency here.

try to prepare rvm and install ruby1.9.2, and install gem then.

2. Install on Ubuntu
Install ruby related things
>sudo apt-get install ruby-full ruby1.8-dev libopenssl-ruby build-essential

make sure I installed gem on my system
>gem --version
1.8.6

make sure JAVA is there on my system
>echo $JAVA_HOME
/usr/lib/jvm/java-6-sun

Install buildr
>sudo env JAVA_HOME=$JAVA_HOME gem install buildr

Other commands to upgrade a new version or install a specific version:
>sudo env JAVA_HOME=$JAVA_HOME gem update buildr
>sudo env JAVA_HOME=$JAVA_HOME gem install buildr -v 1.4.3

>sudo buildr test
error message:
RuntimeError : Are we forgetting something? JAVA_HOME not set.

solutions:
>sudo env JAVA_HOME=$JAVA_HOME buildr test

3. Install on windows
Install ruby tools on windows first http://rubyinstaller.org/downloads/archives, download the file with version 1.8.6
http://rubyforge.org/frs/download.php/71066/rubyinstaller-1.8.6-p398.exe

set JAVA_HOME

execute the install command
>gem install buildr --platform nswin32

error message:
'make' is not recognized as an internal or external command, operable program or batch file.

solution:
Install the DEVKIT, update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'

Add this directory to path: D:\tool\devkit\bin

Fix this problem, but other problem accured. My windows system is 64bit win7.

error message:
jniwrap.h:24: error: 'long long long' is too long for GCC
jniwrap.h:24: error: 'long long long' is too long for GCC
jniwrap.h:24: warning: useless type name in empty declaration

Solutions:
try install MinGW via this URL http://sourceforge.net/projects/mingw/files/

>gem install buildr --platform x86-nswin32

The problem is still there, maybe that is something related to my 64-bit system. I fail to install this on windows.

I tried to update my ruby to 1.9.2 and update my gem.

Using this command to check the envrionment
>gem evn

>gem install rjb --platform x86-mswin32
>gem install buildr --platform x86-nswin32

edit the file in this directory D:/tool/Ruby192/lib/ruby/gems/1.9.1/gems/rjb-1.3.3/ext/jniwrap.h, change the line
from
typedef long long __int64;
to
typedef long long long64;

>cd D:/tool/Ruby192/lib/ruby/gems/1.9.1/gems/rjb-1.3.3/ext
>make
>make all
>make install
>cd ..
>gem spec ../../cache/rjb-1.3.3.gem --ruby > ../../specifications/rjb-1.3.3.gemspec

try again
>gem install buildr --platform x86-nswin32
>buildr --version

successful here. but error message in next steps
>buildr compile
error message:

>gem uninstall rjb -v 1.3.3

rollback my ruby to 1.8.6, and gem 1.3.7
>gem install rjb -v 1.3.8 --platform x86-mswin32-60 
>env JAVA_HOME=D:\tool\jdk1.6 gem install buildr -v 1.4.6 --platform x86-nswin32-60

new error message:

solutions:
>gem uninstall rjb -v 1.3.3
>gem list

In the mean time, change the file jniwrap.h
>gem uninstall buildr -v 1.4.6

rollback back to 1.9.2
>gem install rjb -v 1.3.4 --platform ruby

>cd D:/tool/Ruby192/lib/ruby/gems/1.9.1/gems/rjb-1.3.4/ext
>make
>make all
>make install
>cd ..
>gem spec ../../cache/rjb-1.3.4.gem --ruby > ../../specifications/rjb-1.3.4.gemspec

Fail at last, I give up here.

4. Check the Installation
>sudo buildr --version
Buildr 1.4.6

5. Running Buildr
put a buildfile on that directory. Something like ant,
#clean and rebuild
>sudo buildr clean build
>sudo buildr install

The related things are ruby, rake, antwrap, yaml.
