Segment fault using Getting Started Guide on Ubuntu 16.06 about magnum-bootstrap HOT 4 CLOSED

huh.

I would need to check, the only time I saw cmake crash was when I accidentally called add_subdirectory() in a way that made cmake recurse infinitely. Can you post the "seemingly from glfw" errors?

Sure, absolutely:

Sorry for the very late reply -- I tried on my side with base project from magnum-bootstrap with latest corrade and magnum added via add_subdirectory() but couldn't reproduce either of the problems you have -- with WITH_SDL2APPLICATION=ON it just found everything and running make was then successfull, without it CMake rightfully complained that find_package(Magnum REQUIRED Sdl2Application) couldn't found the Sdl2Application component.

The problem you are describing could be caused by some unfortunate combination of outdated FindMagnum.cmake/FindCorrade.cmake/FindSDL2.cmake modules in either of the projects.

@mosra Problem resolved, must have been a transient issue.
