Hi Guys,
I am a new beginner of Rust, I have run a little example of orbtk, But I have got the following errors:

Caused by:

I have already installed libXext by yum, but the error is still there.

Please give me help. Thanks!

Hi Sir, I have already installed the libXext-devel.x86_64 and libXext-devel.i686, but the error is stiil there.

Some ENVs are:
Centos 7.5
RUST 1.50.0
GCC 9.3.0
CMake 3.19.3

The Xext.h is /usr/include/X11/extensions/Xext.h.

RUST run other none-gui example is ok.

And also I found some information in sdlchecks.cmake as bellow:
macro(CheckX11)
if(VIDEO_X11)
foreach(_LIB X11 Xext Xcursor Xinerama Xi Xrandr Xrender Xss Xxf86vm)
FindLibraryAndSONAME("${_LIB}")
endforeach()

find_path(X_INCLUDEDIR X11/Xlib.h
    /usr/pkg/xorg/include
    /usr/X11R6/include
    /usr/X11R7/include
    /usr/local/include/X11
    /usr/include/X11
    /usr/openwin/include
    /usr/openwin/share/include
    /opt/graphics/OpenGL/include
    /opt/X11/include
)

if(X_INCLUDEDIR)
  list(APPEND EXTRA_CFLAGS "-I${X_INCLUDEDIR}")
  list(APPEND CMAKE_REQUIRED_INCLUDES "${X_INCLUDEDIR}")
endif()

check_include_file(X11/Xcursor/Xcursor.h HAVE_XCURSOR_H)
check_include_file(X11/extensions/Xinerama.h HAVE_XINERAMA_H)
check_include_file(X11/extensions/XInput2.h HAVE_XINPUT_H)
check_include_file(X11/extensions/Xrandr.h HAVE_XRANDR_H)
check_include_file(X11/extensions/Xrender.h HAVE_XRENDER_H)
check_include_file(X11/extensions/scrnsaver.h HAVE_XSS_H)
check_include_file(X11/extensions/shape.h HAVE_XSHAPE_H)
check_include_files("X11/Xlib.h;X11/extensions/xf86vmode.h" HAVE_XF86VM_H)
check_include_files("X11/Xlib.h;X11/Xproto.h;X11/extensions/Xext.h" HAVE_XEXT_H)

The X_INCLUDEDIR does not include " /usr/include/X11/extensions".

I don't know whether it is a fault, and also I don't how to do next.

It looks like a problem when building sdl2-sys specifically. There might be some luck to be had googling around that?

The log file(s) might be helpful to read.

That's a bit alarming. You should only need one of these, installing both is possibly(?) a problem. You probably want to keep libXext-devel.x86_64 as it is for 64 bit systems, which I assume you have. Could be worth double checking? - more googling to do :slight_smile:

These are just some guesses. My only other advice is to search GitHub issues on orbtk and sdl2-sys to see if this has been solved before. If not, it is probably worth raising an issue yourself
