View source for How to compile

These are instructions for compiling ToME4 on Debian Linux.  If you haven't done so already, see [[Source Setup]] for obtaining the source code.

Building ToME4 beta 43 or higher requires snapshots of the currently unreleased [http://www.libsdl.org/hg.php SDL 2.0] library (also referred to as '''SDL HG'''). Most operating systems only supply the latest stable release, SDL 1.2, which '''will not work''' for ToME4.

In addition, you will need SDL2-compatible versions of the SDL_image and SDL_ttf libraries. Again, these are typically not available from your operating system distributor, because they are in a prerelease state. The instructions on this page will guide you through the process of building these from source.

==Addons==
The ToME 1.0.0RC1 (and later) source code in Git/SVN is incomplete. You must install "addons" which are not part of the Git/SVN tree in order to get all the game features. The procedure recommended by DarkGod is to download one of the official releases, extract the addon files from it, and copy them into the tree.

NOTE: If you download the source from [https://te4.org/download te4.org] '''the addons are included''', except for the Stone Wardens.

If you prefer to avoid doing that, the addons are available from a third-party site:

Copy these into the '''game/addons/''' subdirectory once you've followed the rest of the instructions below.

Addons are version-locked to the specific ToME version for which they are bundled, ''except'' ToME versions above 1.0.1, which can use the 1.0.1 addons.

==SDL==
ToME beta 43 was built with the prerelease versions of SDL2, SDL2_image and SDL2_ttf available on November 25, 2012. Later versions may also work, depending on the stability of the library's interface. For reference, the following hg revision numbers are known to work:
*SDL revision 6687
*SDL_image revision 339
*SDL_ttf revision 222
(You should try the current SDL2 first, and only fall back to these older versions if necessary.)

Install prerequisite development packages for your operating system.  You'll need mercurial (hg), C and C++ compilers, make, autoconf and friends, and the development packages for X, libopenal, libogg, libvorbis, libpng, libglu1-mesa, libfreetype, libasound, and libaudiofile.

For Debian, this might work:
 sudo apt-get build-dep libsdl1.2debian
 sudo apt-get install subversion mercurial autoconf automake libtool

If that doesn't work, then this may get you close:
 sudo apt-get install build-essential subversion mercurial
 sudo apt-get install autoconf automake libtool
 sudo apt-get install libopenal-dev libogg-dev libpng12-dev libvorbis-dev
 sudo apt-get install libglu1-mesa-dev libfreetype6-dev xorg-dev
 sudo apt-get install libasound2-dev libaudiofile-dev

Install the prerelease version of SDL2:
 cd /usr/local/src
 hg clone http://hg.libsdl.org/SDL
 cd SDL
 # OPTIONAL: hg update 6687
 ./autogen.sh
 cd ..
 mkdir SDL-build
 cd SDL-build
 ../SDL/configure && make && sudo make install
 sudo ldconfig

Install the prerelease version of SDL_image:

 cd /usr/local/src
 hg clone http://hg.libsdl.org/SDL_image
 cd SDL_image
 # OPTIONAL: hg update 339
 ./autogen.sh
 cd ..
 mkdir SDL_image-build
 cd SDL_image-build
 ../SDL_image/configure && make && sudo make install
 sudo ldconfig


Install the prerelease version of SDL_ttf:

 cd /usr/local/src
 hg clone http://hg.libsdl.org/SDL_ttf
 cd SDL_ttf
 # OPTIONAL: hg update 222
 ./autogen.sh
 cd ..
 mkdir SDL_ttf-build
 cd SDL_ttf-build
 ../SDL_ttf/configure && make && sudo make install
 sudo ldconfig

Note, the configure command might throw errors about Freetype2. Installation instructions can be found [http://www.linuxfromscratch.org/blfs/view/svn/general/freetype2.html here].

At this point you should have headers in '''/usr/local/include/SDL2/''' and libraries in '''/usr/local/lib/'''. The libraries should be named libSDL2, libSDL2_image and libSDL2_ttf (with appropriate version numbers and extensions). If any of the SDL libraries fail to build, check the [http://www.libsdl.org SDL website] for assistance.

==Premake4==
Install premake4 from your distro:
 sudo apt-get install premake4

Another option is to install premake4 from https://premake.github.io/

Note: if your OS has a "premake" version 3 package, that ''will not'' work.

==ToME4==
Decide where you'll keep the ToME source code. You'll need about 1 gigabyte of space. Let's assume you're going to use /usr/local/src/t-engine4. Make this directory and make sure you have write permission.

Fetch the ToME sources:
 cd /usr/local/src
 git clone http://git.net-core.org/tome/t-engine4.git

Your local copy of the Git repository will contain ''every version'' of ToME source code up to the time you did the clone, and you will be "checked out" in the bleeding edge master branch by default.  So, if you want to build a stable version of ToME, you need to specify which one:
 cd t-engine4
 git checkout tome-1.1.3       # or whichever remote tag you wish to "check out"

Check, and possibly edit, '''premake4.lua''' and '''build/te4core.lua''' to reflect the location of your SDL installation.
* In premake4.lua, make sure "/usr/local/include/SDL2" appears before any other SDL directory in the includedirs section.
* In build/te4core.lua, under the configuration "linux" section, make sure "/usr/local/lib/" appears on the libdirs line, and make sure "SDL2", "SDL2_ttf", "SDL2_image" appear on the links line.

Now to compile, you just do:
 cd /usr/local/src/t-engine4
 make clean; premake4 clean     # Don't worry if these fail.
 premake4 gmake
 make

To upgrade to a new version:
 cd /usr/local/src/t-engine4
 make clean; premake4 clean     # Don't worry if these fail.
 git fetch origin
 git merge origin
 git checkout tome-x.y.z        # Fill in the appropriate remote tag name

Then you need to check/edit '''premake4.lua''' and '''build/te4core.lua''' again (every time, ''sigh''), and then finally:
 premake4 gmake
 make

==Troubleshooting==
=====SDL Lua font error=====
If you get an error like this:

 Lua Error: /engine/utils.lua:666: could not load font: /data/font/Vera.ttf (12)

It means you've linked against the wrong versions of SDL_image and/or SDL_ttf. Make sure ToME is linked against the ''new'' versions, which have "SDL2" in their names.

=====SDL video: No available video device=====
If you get an error like this:

 Error initializing SDL video:  No available video device

It probably means you didn't have all the development packages installed when you built SDL.

=====OpenAL=====
If you get an error like this:

 In file included from ../src/main.c:41:
 ../src/music.h:43:10: fatal error: AL/al.h: No such file or directory
  #include <AL/al.h>

It means you don't have OpenAL libs and/or headers installed. Install both using:

 sudo apt-get install libopenal1 libopenal-dev

=====Vorbis=====
If you get an error like this:

 In file included from ../src/main.c:41:
 ../src/music.h:45:10: fatal error: vorbis/vorbisfile.h: No such file or directory
  #include <vorbis/vorbisfile.h>

It means you don't have the Vorbis libs and/or headers installed. Install both using:

 sudo apt-get install libvorbis0a libvorbis-dev
