Compiling this on Linux is fairly easy, and the requirements are not steep. I do it on my from-scratch system and it's always been basic dependencies I've already had.
https://github.com/RobertBeckebans/RBDO ... pile_linux
Essentially, the dependencies (outside of a basic dev environment, gcc toolchain and appropriate dev packages) are:
git
cmake
SDL
OpenAL
ffmpeg
This is how I do it.
Code: Select all
git clone --recursive https://github.com/RobertBeckebans/RBDOOM-3-BFG.git
Now, the business end of this is the "neo" directory and it's where we operate from. The configuration is in a script, neo/cmake-linux-release.sh
Code: Select all
cd ..
rm -rf build
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DONATIVE=ON -DFFMPEG=OFF -DBINKDEC=ON ../neo
The bottom line is what configures the build. There shouldn't be any reason to change that, but that's where you'd add/change cmake configuration parameters. If building it for yourself, to run on that system, use -DONative=ON. That will use -march=native. Turn it off if you expect it to run on other CPUs. This will use -O3 optimization level for a Release build.
If you want to drive that shit yourself, turn ONATIVE OFF and specify your own flags in the command like this:
Code: Select all
-DCMAKE_C_FLAGS:STRING="-O3 -march=nehalem" -DCMAKE_CXX_FLAGS:STRING="-O3 -march=nehalem"
Substituting your CPU type for nehalem in the example, of course.
So, after cloning with git and considering the cmake configuration:
Code: Select all
cd RBDoom3BFG/neo
./cmake-linux-release.sh
cd ../build
make -j10
Adjust the -j value for the number of cores you want to use (actually the number of make jobs you want to start)
After configuring with cmake, you run GNU make like normal as in the above list of commands.
That shouldn't take very long to build, a few minutes for most people. After that, we'll just take the game binary.
Read the instructions on the site, but essentially:
Code: Select all
copy base directory from steamapps/common/Doom3 BFG Edition to game directory.
copy build/RBDoom3BFG to game directory (where you put base)
There should only be a few megs of symbols on a release build of this, but you can strip it with:
Code: Select all
strip -p --strip-unneeded RBDoom3BFG
(That's my safe strip command I use for everything, preserves timestamps and doesn't break libraries. On binaries, that strips all anyway)
By game directory, I mean whatever directory you decide to run this game out of. Don't replace shit in your Steam directory or wherever the Doom3 BFG game files are, copy the base directory from it.
Now, I don't know if this is in any instructions anywhere, but additionally you will need to take (from the source directory):
and copy that directory to the base directory (containing the official game files) in your game installation directory. If you don't, the game will instantly abort.
That should be it. Simply run RBDoom3BFG and adjust the graphics settings to your taste. This has Doom, Doom 2, and Doom 3 + Expansions. When you go into the Doom 3 BFG Edition choice. it also has a Dev menu where you can choose whatever chapter of the game or expansions you want to start at.
Console and Doom 3 commands (e.g. "god") work as expected.
