Score.cpp refused to compile without adding #include <cmath> // std::ceil about tracks HOT 5 OPEN

Haven't got much experience with debug and backtrace.... but I compiled both Tracks and SFGUI 0.3.1 with cmake -DCMAKE_BUILD_TYPE=Debug ..
and ran Tracks via catchsegv ./Tracks -o hai
which results in:
$> catchsegv ./Tracks -o hai

Hello,

Thank you for bringing this up!

Would you be able to say which versions of the various libraries were used - did you pull the latest from github? I believe that the latest versions of SFML and SFGUI in particular don't play well, so possibly I should amend the readme to link to specific releases.

I will also have a look with GCC 6.x

from tracks.

I have SFML 2.3.2-1.2 installed from the OpenSuse Repo.
I installed SFUI 0.3.1 but then later I think I pulled it from the github repo.
Segfault is still reproducible.

from tracks.

Thank you - the missing header has now been added.

I was not able to reproduce the segfault with SFML 2.3.2, SFGUI 0.3.1 and GCC 6.2.0, on Ubuntu 16.04. These versions are fairly close to what Tracks was developed with. In 2.4 an incompatibility between the two libraries emerged, which has now been fixed: TankOs/SFGUI#36

I will strive to test on OpenSuse with GCC 2.6.1. Is there any chance you could build the libraries and Tracks with Debug flags and post the backtrace, as well as any messages on stdout/stderr? That would help tremendously.

from tracks.

Thank you - it is much appreciated. The backtrace suggests that the segfault occurs in the internals of the Thor library.

I am leaving this open, but meanwhile please see my email about the future of Tracks!
