ubuntu-12.04

I tried to install Nokogiri on my Ubuntu 12.04 system, and got an error that said " libxslt is missing ", but the libxslt-dev and libxml2-dev are installed. Is there a robust installation process? How can I check the links to dependent libraries? I used RVM, and the RVM pkg is installed too. ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /home/victor/.rvm/rubies/ruby-1.9.3-p125/bin/ruby extconf.rb checking for libxml/parser.h... yes checking for libxslt/xslt.h... yes checking for libexslt/exslt.h... yes checking for iconv_open() in iconv.h... yes checking for

I'm about to update default GCC (version 4.6.3) shipped by Ubuntu 12.04 to 4.8.2, though the compilation requires a standalone C++ compiler admin@ubuntu: /usr/local/gcc_build$ sudo make ends up with configure: error: C++ compiler missing or inoperational make[2]: *** [configure-stage1-libcpp] Error 1 Therefore I turn to the process of g++ installation with a preference to the latest version, which means that I would like to compile from source directly rather than apt-get . But seriously, I can't find the source anyway!(O_o). On the other hand, does the source of GCC also come along with that

How do I install CLang on Ubuntu, using precompiled binaries of CLang that I downloaded? Here's how I downloaded CLang: "LLVM Download Page" -> "Download LLVM 3.2" -> "Clang Binaries for Ubuntu-12.04/x86_64" ( http://llvm.org/releases/3.2/clang+llvm-3.2-x86_64-linux-ubuntu-12.04.tar.gz .) Then, I expanded the archive into a folder on my Ubuntu 12.04 LTS 64-bit machine. The contents of the expanded folder look like this: $ ls clang+llvm-3.2-x86_64-linux-ubuntu-12.04 bin docs include lib share Question: What do I do next? Do I have to copy these into some folders myself, and if so, which ones

This appears to be a common problem on 12.04. I've tried everthing in this thread including: sudo apt-get clean sudo apt-get autoclean sudo apt-get remove --purge mysql-client-5.5 mysql-client-core-5.5 mysql-common mysql-server mysql-server-5.5 mysql-server-core-5.5 sudo apt-get install mysql-server I still get the same old error. Installing/starting MySql5.5 looks like this: apt-get install -f mysql-server Reading package lists... Done Building dependency tree Reading state information...

I installed Scala on Ubuntu using the following sudo apt-get install scala ~$ which scala /usr/bin/scala ~$ whereis scala scala: /usr/bin/scala /usr/bin/X11/scala /usr/share/man/man1/scala.1.gz ~$ scala -version Scala code runner version 2.9.1 -- Copyright 2002-2011, LAMP/EPFL My question is what should I put in the variable SCALA_HOME? /usr/bin ? Tim Perry Today I installed scala using "apt-get install scala" and confirmed the scala jar files are located in /usr/share/java You should be able to set your SCALA_HOME to /usr/share/java and have it all work. I assume you want to use NetBeans so

I'm using Ubuntu 12.04 LTS linux on my machine. I've already installed LAMP on it. Now I want to enable the mod_rewrite module. I did google a lot and tried lots of tricks but couldn't be able to enable mod_rewrite. Can anyone help me to enable the mod_rewrite? Thanks in advance. TL;DR version -- do the following in your terminal: sudo a2enmod rewrite && sudo service apache2 restart With explanations -- do the following in your terminal: ls -l /etc/apache2/mods-available/rewrite.load ///if it prints out rewrite.load, it's there and ready to go sudo a2enmod rewrite //enables the mod ls -l /etc

I've just installed a Ubuntu 12.04 server and nginx 1.2.7, removed default from sites-enabled and added my own file into sites-available and symlink at sites-enabled . Then restarted nginx. Problem: However going to the URL does not load the site. netstat -nlp | grep nginx and netstat -nlp | grep 80 both returns no results! lsof -i :80 also returns nothing. A dig from another server returns the correct ip address so it shouldn't be a DNS problem. I was able to connect to apache which I have now stopped its service. nginx logs also show nothing. How should I troubleshoot this problem? /etc
