Experimental patches #5

Closed tlk closed 3 years ago

tlk commented 3 years ago

The ImageMagick configure script runs a number of compiler tests to check for the existence of libraries such as libxext and libxt (-lXext -lXt).

When the configure script is checking for XShmAttach in -lXext it does so by testing that -lXext is present but without testing if X11/extensions/XShm.h can be included.

This check enables MAGICKCORE_HAVE_SHARED_MEMORY This causes MagickCore/xwindow.c to include X11/extensions/XShm.h This causes the make install step to fail

As an experiment, the configure script is patched to test for the existence of X11/extensions/XShm.h (see the bottom of this file).

In addition, the configure script is patched to align with a vanilla build of ImageMagick.

These patches allows the project to build but the display wizard segfaults.
