Crash on FreeBSD

[Robert Clausecker]

Dear Hugin users,

A FreeBSD user reports that Hugin fails during runtime with a GLEW
error. Here's the error message:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296330

Please let me know if this is a known issue or if you can assist.

Yours,

From INSTALL_cmake

On Linux wxWidgets 3.1.5 and later is by default compiled with EGL support for the wxGLCanvas class.
In this case you need to activate EGL support explicitly also in GLEW, otherwise there are crashes when
intializing the wxGLCanvas. Alternatively you can also use the epoxy library instead of GLEW, which does
the detection at run time. To build with epoxy add -DBUILD_WITH_EPOXY=on to the CMake command line.

Hi T. Modes,

Our ports build GLEW with default options, which should include EGL
support. I presume that the user perhaps has a GPU too old to support
EGL?

Yours,
Robert Clausecker

Hi Robert,

AFAIK the default options don't include egl. You need to explicitly include EGL support:

Also check the build options of wxWidgets. GLEW and wxWidgets should match: using either GLX or EGL.

(Default for wxWidgets is EGL, for GLEW it is GLX).
