Build fails about splishsplash

[janbender]

The openmp errors should be fixed in the current version. The problem was a missing compiler flag in the debug build. However, I cannot reproduce the C++11 problem.

So,how to solve the openmp errors?

Okay, so the errors related to openmp are gone now, thanks! However, I still get the following error:

/usr/include/c++/5/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

I've tried setting the cmake environment variables to reflect the ISO C++ 2011 standard, but no luck. It should be noted that I don't have much experience with cmake, so it's possible I'm overlooking something trivial. I'm building the project using:

cmake CMakeLists.txt -DCMAKE_CXX_COMPILER="/usr/bin/g++" -DCMAKE_CXX_FLAGS="-std=c++11" -DCMAKE_CXX_STANDARD=11

This is strange since I set the C++11 standard in the common.cmake file:

set(CMAKE_CXX_STANDARD 11)

So, I' building from a new system now: Linux x86_64, 4.15.0-42-generic, Ubuntu 18.04.01, g++ 7.3.0.

ISO C++ problems appears to be gone, however the OpenMP errors are back:

SPlisHSPlasH/Utilities/PoissonDiskSampling.cpp:127:25: error: ‘omp_get_max_threads’ was not declared in this scope

I'm giving up on this now, maybe next year. Merry Christmas 🎄

Try to build it in release mode:

cmake -DCMAKE_BUILD_TYPE=Release

Building with cmake -DCMAKE_BUILD_TYPE=Release works. Thanks for helping! Can't wait to play with this during Christmas holidays 😃
