From Ubuntu Server to Debian...

I have had a few issues with Ubuntu's 16.04 release, notably on the server side, when removing the physical network wire on one connection, it would stay connected on another, reconnecting the wire it'd not come back up.

I tried this with wireless connections, with physical RJ45 and virtual devices in various guises, none of them worked right for my needs.

And loathed as I am to change to anything else, I'm currently in the middle of setting up and using a new purely Debian based server... Watch this space....

SDL2.0 Complete Installation on Ubuntu

I've just spent sometime, setting up SDL for development on my Ubuntu machine, and found that the Ubuntu library caches lack SDL v2.0, they have the older 1.2, but that wasn't good enough, so here is a little script I've put together, to get me all the dependencies (least what I think the dependencies are), download each part of SDL (SDL, TTF, Mixer & Image), extract them into folders, build and install them, and then delete the folder copy which was extracted.

cd ~

sudo apt-get install build-essential xorg-dev libudev-dev libts-dev libgl1-mesa-dev libglu1-mesa-dev libasound2-dev libpulse-dev libopenal-dev libogg-dev libvorbis-dev libaudiofile-dev libpng12-dev libfreetype6-dev libusb-dev libdbus-1-dev zlib1g-dev libdirectfb-dev

wget https://www.libsdl.org/release/SDL2-2.0.3.tar.gz

tar -xvzf SDL2-2.0.3.tar.gz

cd SDL2*

./configure

make

sudo make install

cd ~

rm -rf SDL2-2*

wget https://www.libsdl.org/projects/SDL_image/release/SDL2_image-2.0.0.tar.gz

tar -xvzf SDL2_image-2.0.0.tar.gz

cd SDL2_image*

./configure
make

sudo make install

cd ~

rm -rf SDL2_image*

wget https://www.libsdl.org/projects/SDL_ttf/release/SDL2_ttf-2.0.12.tar.gz

tar -xvzf SDL2_ttf-2.0.12.tar.gz

cd SDL2_ttf*

./configure

make all

sudo make install

cd ~

rm -rf SDL2_ttf*

wget https://www.libsdl.org/projects/SDL_mixer/release/SDL2_mixer-2.0.0.tar.gz

tar -xvzf SDL2_mixer-2.0.0.tar.gz

cd SDL2_mixer*

./configure

make all

sudo make install

cd ~

rm -rf SDL2_mixer*

sudo ldconfig

Once this is all done, you need to edit /etc/ld.so.conf adding to it, thus:

sudo nano /etc/ld.so.conf

And add:

include /usr/local/lib

Save the file, I can now create an empty C++ project, or just a main.cpp, and include the following files:

#include <SDL2/SDL.h>

#include <SDL2/SDL_image.h>

#include <SDL2/SDL_ttf.h>

#include <SDL2/SDL_mixer.h>

The libraries to link against are:

libSDL2.a

libSDL2_image.a

libSDL2main.a

libSDL2_mixer.a

libSDL2_test.a

libSDL2_ttf.a

(Each .a also has a static .so, alongside, if you prefer)

This, of course the linker options on the command line are:

g++ --std=c++11 main.cpp -llibSDL2.a -llibSDL2_image.a -llibSDL2main.a -llibSDL2_mixer.a -llibSDL2_test.a -llibSDL2_ttf.a
