BuildInstructions
Most of the current development work is done on Ubuntu Linux. Building the code on any Linux variant should be relatively straightforward. Building it on Windows or Mac OS X is a bit more complicated.
You can get a copy of the code either using "git clone," or using the download link. How you build it will then depend on your operating system:
Use your favorite package manager to install the following (version numbers may vary depending on your distribution):
- g++
- scons
- libsdl2-dev
- libpng12-dev
- libjpeg-turbo8-dev
- libgl1-mesa-dev (or some other equivalent)
- libglew-dev
- libopenal-dev
You can then just navigate to the source code folder in a terminal and type:
$ scons
$ ./endless-sky
The program will run using the "data" and "images" folders that are found in the source code folder itself. For more Linux help, consult the man page (endless-sky.6).
The Windows build has been tested on 64-bit Windows 7, only. You will need the Code::Blocks IDE and g++ 4.8 or higher. Code::Blocks is available here, and you can install g++ separately through mingw-w64. Be sure to install the "pthread" version of MinGW; the "win32-thread" one does not come with support for C++11 threading. On 32-bit Windows, use "dwarf" exceptions, not "sjlj". Then you'll need to tell Code::Blocks the path to the compiler programs:
If you are on 64-bit Windows, a full set of development libraries are available here. If you don't want to have to edit the paths in the Code::Blocks file, unpack the "dev64" folder directly into C:\.
If you are using 32-bit Windows, download the 32-bit libraries instead. In the Code::Blocks project, you will have to select the "Win32" build, and set up your compiler paths to point to a 32-bit compiler.
You will also need libmingw32.a and libopengl32.a. Those should be included in the MinGW g++ install. If they are not in C:\Program Files\mingw64\x86_64-w64-mingw32\lib\ you will have to adjust the paths in the Code::Blocks file.
On Windows certain files with "~" in the file name may be spontaneously deleted by git with an "error: Invalid Path" message when pulling or merging. The solution is to set git config core.protectNTFS false.
To build Endless Sky you probably want the latest XCode version (I used 5.1.1). You also need to install three libraries:
####libpng####
http://sourceforge.net/projects/libpng/files/libpng14/
Get version 1.4.13. (The version number doesn't seem to match -- XCode links to libpng14.14.dylib -- but the file name will be right).
On my system, it was installed with the name libpng14.14..dylib (extra ".") and I had to rename it and fix the symlinks.
####libturbojpeg####
http://www.libjpeg-turbo.org/Documentation/OfficialBinaries
####SDL2####
Just downloading the SDL binary won't work, because XCode 5 checks that the framework is signed, and it isn't. Instead, build it from source:
hg clone https://hg.libsdl.org/SDL open SDL/Xcode/SDL/SDL.xcodeproj
Build the framework, then copy it into /Library/Frameworks. When I did this, for some reason it built to some obscure directory that I had to look up in the logs.
Hopefully these will all install to the locations referenced in the project file; if not you can correct the paths.
####Library paths####
To create a Mac OS X binary that will work on systems other than your own, you may also need to use install_name_tool to modify the libraries so that their location is relative to the @rpath.
