autistdraw
|
||||||
|
==========
|
||||||
|
|
||||||
|
`autistdraw' will be a terminal drawing application with multiplayer support.
|
||||||
|
|
||||||
|
Building and Running
|
||||||
|
--------------------
|
||||||
|
Build dependencies: GCC/Clang, pkg-config, GNU make, Jansson, cURL, readline
|
||||||
|
|
||||||
|
If you don't have Clang, you can edit the Makefile to use GCC or TCC, they work
|
||||||
|
just as good. But there's no CMake support yet, so I force it in the Makefile.
|
||||||
|
|
||||||
|
$ git clone https://github.com/pjanouch/autistdraw.git
|
||||||
|
$ git submodule init
|
||||||
|
$ git submodule update
|
||||||
|
$ mkdir build
|
||||||
|
$ cmake .. -DCMAKE_BUILD_TYPE=Debug
|
||||||
|
$ make
|
||||||
|
$ ./autistdraw
