Compiling Doom64EX from source "Make" Error.

Recommended Posts

Hello all.


I am running Arch Linux x86_64, and attempting to compile Doom64 EX for Linux.


You can find the project here.


The issue is, in the README.MD file, it references  a "fluidsynth-lite". And when I attempt to compile (just with make) it crashes, saying the following:

What would you recommend I do?


I don't usually compile things from source haha.


Edit: I just want to add that I'm REALLY frustrated by this. I know that its undoubtedly my fault and that I'm missing something really obvious but its just SO ANNOYING!

Are you running cmake before make?

I don't know if it will apply for you or not on Arch, but here's what I did on Slackware64-Current:


Downloaded the source zip, extracted, made a new directory in the folder called 'build'


In terminal I moved to the build folder

Typed in:

cmake ..




I have cmake-3.12.1-x86_64-1 and fluidsynth-1.1.10-x86_64-2 packages installed.


Afterwards you need to follow the ## Data Files step in README.md to get up and running.

Paste your terminal output you get after running cmake.


For some reason it's trying to compile fluidsynth which doesn't seem necessary if you already have it.


If you still have troubles you could try just using my compiled binary. It might not behave right if your fluidsynth files aren't detected though.. also you'll have to source doom64.wad and doomsnd.sf2 using the wadgen function detailed in the source's readme.

So unsurprisingly by your build attempts fluidsynth isn't detected. What version do you have? Is it a x86_x64 version? If the dependencies listed are satisfied I imagine it should be able to compile it.



If nothing else you could grab fluidsynth from https://github.com/FluidSynth/fluidsynth/releases

Compile that yourself and then attempt compiling Doom64ex again. Could be something with the fluidsynth from your distros package manager. I just used the one on slackbuilds (Basically my distros packages).

Well, I don't know if it matters, but I am installing some optional dependencies, which might help.


I have the x86_64 version AFAIK.


I'm not very wise with pacman and its man page confuses me, so I'm not super knowledgeable, but I think its 64 bit.


Thank you for helping me by the way. I really appreciate it!

Hey, so I think I got it fixed. Towards the top of the README.MD, it actually says that to use the system's fluidsynth, I need to use



instead of

cmake ..

I will test this now.


Sorry for the triple post, I know that its frowned upon, but I think it was appropriate in this case.

Interesting.. not sure why I didn't have to do that.


I'm not familiar with pacman specifically but I would assume that when a package is installed it puts the dependencies into the appropriate lib folder, gives the file itself whatever name it wants, then creates the general named link file to point to it.


In my case I found libfluidsynth.so in /usr/lib64

This file is a link to libfluidsynth.so.1, which itself is a link to libfluidsynth.so.1.7.1, which is the actual dependency from what I can tell.


The idea being I imagine that programs would only know to look for the general .so file, not specific versions of it.. hence the use of links.


I'm not very linux savvy myself though so I could be off.
