Errors compiling on Ubuntu 18.04 with SFML 2.5.1

[SnowySailor]

I installed SFML once from source and once using the precompiled libraries for Linux here: https://www.sfml-dev.org/download/sfml/2.5.1/ (also tried 2.5.0).

Everything up until cmake --build build worked fine. Once I ran that command, however, I got the following error:

Seems to be something to do with SFML, but I'm not sure exactly what. I thought it was something to do with the specific library I installed, but I got the same error when using the precompiled one. Any ideas?

Thanks

SFML supports 2 types of libraries, static and dynamic, and this error can occur if you mix them. I use static libraries in my builds with the SFML_STATIC preprocessor flag, not sure if the same is true on Linux...

@SnowySailor can you explain to me how you installed SFML, the contents of the downloaded zip make no sense. I too use ubuntu and I have no idea how to get this game up and running.

here's what i tried :

git clone https://github.com/HackerPoet/MarbleMarcher.git
git checkout shader-backport #did not work
sudo apt install cmake libeigen3-dev libsfml-dev libboost-dev libboost-system-dev libboost-filesystem-dev
cd MarbleMarcher/
mkdir build
cmake -SFML_STATIC

if i understand correctly in order to have the two dependencies : eigen3 and sfml

libeigen3-dev and libsfml-dev are suitable libs.

you will need libsfml 2.5 packages and ubuntu 18.04 repositories doesn't have them, i downloaded .deb packages from ubuntu 18.10 repositories
if you have libsfml 2.5 packages remove -SFML_STATIC and build again
hope it helps ;)

BTW I was able to get this to build on Ubuntu 18.04 w/ SFML 2.5.1 (but building from source), and submitted this PR: #39

Not sure if it'll resolve the static vs. shared linking, but it at least gets things going.

@tuxutku Could you link to the deb, please?

As i was not sure and it took me some time to get it working i am gonna post a summary.

How to build and run MarbleMarcher on Ubuntu 18.04

• install libsfml-dev version 2.5.0
  • 18.04 has dependency package libsfml-dev version 2.4.1, MarbleMarcher needs 2.5.0
  • download individual libsfml packages version 2.5.0 for your distribution
    • select your distro (eg Ubuntu 18.10) and platform (amd64)
    • https://pkgs.org/download/libsfml-audio2.5
    • https://pkgs.org/download/libsfml-system2.5
    • https://pkgs.org/download/libsfml-window2.5
    • https://pkgs.org/download/libsfml-network2.5
    • https://pkgs.org/download/libsfml-graphics2.5
    • https://pkgs.org/download/libsfml-dev
  • install them all
    • if in one directory run sudo apt install ./*
• install other dependencies (not sure if this is all you need)
  • sudo apt install libeigen3-dev git cmake make
• get MarbleMarcher source

cd ~
git clone https://github.com/HackerPoet/MarbleMarcher
cd MarbleMarcher

• edit CmakeLists.txt
  • delete SFML_STATIC word (cause we are using the installed deb packages)
• build the MarbleMarcher

( set -eux;
  mkdir build && cd build
  cmake ..
  make -j
  cp MarbleMarcher ..
)

• run the MarbleMarcher via ./MarbleMarcher
