test the repository in a linux environment

[Sidhin S Thomas]

So far the only thing i know is that this builds successfully in linux. Need someone to test it and see if it works in it.

[Sidhin S Thomas]

can you try and build this in linux ?? @prankulsingh

[Gautam krishna R]

i will give it a try 😄

[Sidhin S Thomas]

Thanks @gautamkrishnar that would be really helpful

Had some issues with the build file..

1. While building it is having the following errors:

g++-4.8 -std=c++11 -c src/main.cpp -o build/main.o
make: g++-4.8: Command not found
Makefile:17: recipe for target 'build/main.o' failed
make: *** [build/main.o] Error 127

2. After correcting the make file with g++ command, it is showing another error:

g++ -std=c++11 -c src/main.cpp -o build/main.o
Assembler messages:
Fatal error: can't create build/main.o: No such file or directory
Makefile:17: recipe for target 'build/main.o' failed
make: *** [build/main.o] Error 1

3. Cant execute the app:

bash: ./game.o: cannot execute binary file: Exec format error

• So we need to create the build folder and add .gitkeep to it.

mkdir build
echo > build/,gitkeep

• Update the commands so that the build fails when the required version of g++ is not found.

Ya, I had forgotten about the g++ thing, its due to travis CI.
Anyways, did you copy the dlls ? any idea what's causing it?

[Gautam krishna R]

i had installed the sfml via the apt-get command.
I have no idea why this error!
I will try compiling the files manually...

[Sidhin S Thomas]

Well the target of the build is in same directory as the makefile, you should see a file called game

Then you will need the following dlls in the same folder as executable (in windows that's how it is, linux supports dynamic link right?)

• sfml-graphics-d-2.dll
• sfml-window-d-2.dll
• sfml-system-d-2.dll

[Sidhin S Thomas]

wait, I think you don't need the dlls. You sure you executed the correct thing? can't see it in your screenshot

[Gautam krishna R]

$make
g++ -std=c++11 -c src/main.cpp -o build/main.o
g++ -std=c++11 -c src/game.cpp -o build/game.o
g++ -std=c++11 -c src/food.cpp -o build/food.o
g++ -std=c++11 -c src/snake.cpp -o build/snake.o
g++ -std=c++11 -g  -o game build/main.o build/game.o build/food.o build/snake.o -lsfml-graphics -lsfml-window -lsfml-system

Now I have the build directory with the following files:

$ls build/
food.o  game.o  main.o  snake.o

Now i am checking out the docs on: http://www.sfml-dev.org/tutorials/2.0/start-linux.php

[Sidhin S Thomas]

the executable is not in the build directory.
There should be a game in root directory of the project. That's the file to execute.

[Gautam krishna R]

Executing... But it is just automatically crashing without showing any errors!

@ParadoxZero

[Sidhin S Thomas]

That's some progress. Does it crash immediately?

[Gautam krishna R]

yes i cant even blink my eye 😄

[Sidhin S Thomas]

That's weird, even though the frame was rendered.
Try this,

• Go to game.cpp
• In function gameLopp() remove the exit(0)

[Gautam krishna R]

@ParadoxZero man! the game is working fine... I think you must add a wait before the game is started...
or something like press any key to start the game...

I tried controlling the snake and it worked fine... The game is exiting because it is reaching the end of game (Snake hits the wall)....
😄 Good job...

• Add A wait or key to start before starting the game.
• Must display a game over message before terminating
  

[Sidhin S Thomas]

This is just the core xD
will work on a proper Interface tommorow after the exam.
Didn't get time to build one.
Thanks for the help! 👍 :)

[Gautam krishna R]

👍 ❤️ Great job man... Keep it up, I will work on the makefile and submit a PR Soon 😄

[Sidhin S Thomas]

That would be great! thanks again
