Ubuntu 11.04: Installing GCC 4.4.6

由 纵饮孤独 提交于 2019-12-10 23:51:37
问题 I am trying to install GCC 4.4.6 on Ubuntu 11.04 64 bit and having some trouble. As the package does not ship with this distribution I try to build it from source. It needs GMP and MPFR which I installed from the package system. I am using distinct source, build and install directories as advised. Target=build=host. Except --prefix I do not give any configure options: gcc-4.4.6/configure --prefix=[absolute_path]/install/gcc-4.4.6 These environment variables are also used: CXX=/usr/bin/g++-4.4

I tried to empty my apc.ini files but it didn't worked. Still after I load a page for the first time, the page will be stored in the cached and the second time I load the page, it loads much faster. Here's a PHP file that I use to measure the time. <?php function getTime() { $a = explode (' ',microtime(

OpenCV, Ubuntu 11.04

由 為{幸葍}努か 提交于 2019-12-08 03:40:06
问题 I've been trying to install OpenCV 2.2 on Ubuntu 11.04. As far as I can gather from here: linux/videodev.h : no such file or directory - OpenCV on ubuntu 11.04, the installation fails because video4linux is no longer in the kernel. If I follow the guide linked to in the above thread (http://tech.groups.yahoo.com/group/OpenCV/message/79758), the make-command passes the initial error described in the above thread, but fails at a later point. I get the error: Linking CXX executable ../../bin

MongoDB is not installed properly on Ubuntu 11.04 in Amazon EC2

由 佐手、 提交于 2019-12-07 09:59:33
I'm trying to install MongoDB on my Ubuntu 11.04 AMI in Amazon EC2. I allowed 27017 port in security option. The problem is that I can use "mongo OTHER IP ADDRESS" to access to other mongoDB. But simply "mongo" does not simply give me access to localhost mongoDB. mongoDB shell shows like it is about to work but it stops at MongoDB shell version: 1.8.3 connecting to: test If it is truly connected, it should give me ">" but it doesn't and freezes. I couldn't find answer on freezing problem by googling myself. Also any tips on running mongoDB as daemon or running in background? Be sure to use 0.0

How to setup a OpenGL developement environment without Mesa

由 人盡茶涼 提交于 2019-12-06 09:40:34
According to what i read here: http://www.linuxquestions.org/questions/linux-software-2/opengl-vs-mesa-whats-the-diff-351037/ Mesa is software rendering, while driver OpenGL is hardware rendering. Every tutorial i came accross only show how to install Mesa. How can i set up a true (hardware accelerated) openGL? Does installing driver install the header? If so, which header? If i have a program compilled with mesa, do i have to recompile it to take the advantage of hardware accelerated? If installing the driver install the required library and header, what happen to mesa? From the last post on
