Compile error about devilutionx

Good day and salutations,

I was able to compile this on a clean new system

My history...

   1  apt-get install g++-multilib libc6-dev-i386
    2  apt-get install cmake
    3  apt-get install libsdl2-dev:i386
    4  sudo dpkg --add-architecture i386
    5  sudo apt-get update
    6  vim /etc/resolv.conf 
    7  sudo apt-get update
    8  apt-get install libsdl2-dev:i386
    9  apt-get install libsdl2-mixer-dev:i386
   10  ls
   11  vim usr/lib/i386-linux-gnu/cmake/SDL2/sdl2-config.cmake
   12  history

in file vim usr/lib/i386-linux-gnu/cmake/SDL2/sdl2-config.cmake

# sdl2 cmake project-config input for ./configure scripts

set(prefix "/usr")
set(exec_prefix "${prefix}")
set(libdir "${prefix}/lib/i386-linux-gnu")
set(SDL2_PREFIX "/usr")
set(SDL2_EXEC_PREFIX "/usr")
set(SDL2_LIBDIR "${prefix}/lib/i386-linux-gnu")
set(SDL2_INCLUDE_DIRS "${prefix}/include/SDL2")
set(SDL2_LIBRARIES "-L${SDL2_LIBDIR}  -lSDL2 -lSDL2_mixer ")

I had to comment out an include line in the code which is looking for #include <SDL_image.h>

which I will fix now.

[VonKossa]

I solved it.
Of course there was another sdl2-config.cmake under /usr/lib32/cmake/SDL2. lol
Stupid me. :)

[AJenbo]

This is caused by the linker not finding SDL_mixer, it seams to happen when compiling on a 64bit platform, probably all it needs is a parameter to point it in the right direction. The problem appears to be that the way we force the compiler to 32bit causes auto discover in cmake not to work properly. The issue should go away when either compiling on a 32bit installation, or compiling to a 64bit file (however the code is not in a state where this can be done yet).

@ApertureSecurity might be able to provide some info in regards to what environment he is compiling under.
He is currently working on rebasing the code to the latest devilution, this should help significantly in terms of getting closer to be able to compile to a 64bit target.

[AJenbo]

@VonKossa make sure that you have added -lSDL2_mixer to the /usr/lib/i386-linux-gnu/cmake/SDL2/sdl2-config.cmake file.

[AJenbo]

@ApertureSecurity your history doesn't show you running cmake or make? Do you do that from a GUI tool?

[VonKossa]

Hi again!
Thanks for the answers.

For the record i am running Gentoo, not a debian or debian like distro.
The location for the sdl2-config.cmake seems to be /usr/lib/cmake/SDL2 for me.
I added -lSDL2_mixer like described and compiled both libsdl2 and sdl2-mixer with x86_32 support.
Same error. :(

Are you wanting to compile it or do you just want to play?

I can compile it for you. Ideally , I can just release stable branches of the game.

@AJenbo, I ran cmake ..;make from the build folder. That terminal used for vim on sdl cmake.

[VonKossa]

Actually i want to compile it.
i believe my problem is related to x64/x86 somehow.

My sdl2-config.cmake looks different than yours:

set(prefix "/usr")
set(exec_prefix "${prefix}")
set(libdir "/usr/lib64")
set(SDL2_PREFIX "/usr")
set(SDL2_EXEC_PREFIX "/usr")
set(SDL2_LIBDIR "/usr/lib64")
set(SDL2_INCLUDE_DIRS "${prefix}/include/SDL2")
set(SDL2_LIBRARIES "-L${SDL2_LIBDIR} -lSDL2 -lSDL2_mixer")
string(STRIP "${SDL2_LIBRARIES}" SDL2_LIBRARIES)

[AJenbo]

Hopfully we can get SDL2_mixerfind.cmake working for 32bit builds so that it won't be needed to edit the file :)

[VonKossa]

It did compile and it did start, but that was about all. The game menu appeared but you are unable to choose anything with the keyboard and if you are lucky you might be able to proceed to the choose character menu if you by luck find the right pixel with the mouse. Then it segfaults. :)
I guess this is the current state right now or am i doing something wrong here?

Can you launch it in terminal and give me output before it crashes please.

Thank you for this.

[VonKossa]

sure... just a moment. :)

Segmentation fault

[VonKossa]

well it was hard to find the correct spot to click on, lots of coordinates... . :(

[AJenbo]

Sounds like you might be trying the 64bit branch? The menu is a bit of a work in progress atm, and 64bit crashes as soon as you start the game. The 32bit build should work ok, though the menu is also a bit unfinished.

[VonKossa]

no actually not but i have also studied your progress in the 64-bit branch, great work!
I did compile the master branch but i think the problem has something to do with the mixed environment iḿ running.
No worries.

[AJenbo]

We are working on merging devilution 0.5 and then also most of the stuff in the 64-bit branch, so things should be more interesting in a weeks time :)
I'm hoping that we can get the 64bit up and running in a months time after that.

[AJenbo]

@VonKossa as you might have notice we have merged the code and things should now be in a better state, though 64bit builds currently only gets you to the loading screen. How ever you can force the compiler to 32bit mode by providing FORCE32=1 before running CMake. Hope that helps.

[VonKossa]

It did not work, the menu works as expected but if i try to start a game i am greeted with the message "out of hash space, aborted"

Thanks for your help anyway. :)
