Ubuntu 16 OpenCV 2.4

Problems during compilation:

relocation R_X86_64_32 against `ff_a64_muxer' can not be used when making a shared object

Solution:
recompile ffmpeg-3.4.5 with(2018-11-29):
./configure --enable-nonfree --enable-pic --enable-shared

Download ffmpeg and build 3.4.5, 3.2.12 or 4.0 and try to compile opencv doesn't help, then

Final solution: disable ffmpeg
$cmake  -D WITH_CUDA=OFF -D WITH_FFMPEG=0 ..
$make

That compile opencv 2.4.x and 3.4.x

Mapping files into memory

• CreateFile(); or OpenFile();
• CreateFileMapping();
• MapViewOfFile();
  

mmap() combines the functions of CreateFileMapping() and MapViewOfFile()

Fedora/CentOS Change ports of Apache Web Server (httpd)

1) In file /etc/httpd/conf/httpd.conf

Listen 80
Listen 8079

This till your server to listen to the port 8079

2) virtual host file  /etc/httpd/conf.d/vhost.conf

<VirtualHost *:8079>
 DocumentRoot /var/www/html/api_folder
 ServerName example.com
 ServerAlias www.example.com
 ServerAdmin root@example.com 
 ErrorLog logs/www.example.com-error_log
 CustomLog logs/www.example.com-access_log common

This mean when you go to your www.example.com:8079 redirect to

Update kernel to the latest mainline version without any Distro-upgrade?

To find out which kernel you have type uname -rin terminal.Now type this command to get list of available kernels.

apt-cache search linux-image

this will give you a very big output.Now chose one of them that you want to install and install it by following commands(Don't type these commands like this,replace the word kernal_version with the kernel version which you wish to install)

sudo apt-get install linux-image-kernal_version
sudo apt-get install linux-image-extra-kernal_version
sudo apt-get install linux-headers-kernal_version

Now in my case i choose linux-image-4.10.0-22-generic so my command will look like this

sudo apt-get install linux-image-4.10.0-22-generic 
sudo apt-get install linux-image-extra-4.10.0-22-generic
sudo apt-get install linux-headers-4.10.0-22-generic

now in the end remove old kernel by command

sudo apt-get autoremove

sudo reboot
