layout window not showing on macos

[cheyao]

On my mac layout window the layout window is not showing. Any ideas on why is this happening and how can I fix it?

Here is my configure summary if you need it:

-----------------------------------------------------------
Configuration Summary (principle requirements):

X11:          yes
Python3:      yes
OpenGL:       yes
Vector fonts: yes
Cairo:        yes
Tcl/Tk:       yes
-----------------------------------------------------------

Maybe this has some relationship with that if I set the DISPLAY env variable (to whatever value, for example ":0.0" or "" (blank)) and start up magic on my mac, a text window just blinks for a milisecond and dissapiers gives a seg fault ([1] 60107 segmentation fault magic).

The most likely reason for issues on MacOS is that you are compiling against a version of Tcl/Tk that itself is not X11 compatible.

Did you read the instructions in the repository top level file: https://github.com/RTimothyEdwards/magic/blob/master/INSTALL_MacOS.md ?

[cheyao]

Yes I read the instructions, all dependencies are installed using brew. The only change I made is that I used CC=gcc-12 CXX=g++-12 ./scripts/configure_mac as the configure command.

If I try to use the graphics with cairo, it says that The graphics display couldn't be correctly initialized. instead of the seg fault when using opengl.

And If I use the command openwrapper, there will be this message:

% openwrapper
New windows will not have a title caption.
New windows will not have scroll bars.
New windows will not have a border.
bad window path name ".layout1.pane.top.magic"

and a blank window appears

[RTimothyEdwards]

The blank window is not surprising, given the other errors. If there is a low-level error, then Tk will still likely generate the window frame, but the underlying pixmap will not exist.

The graphics display couldn't be correctly initialized is the result of routine GrTCairoInit() returning FALSE, which it can do for a number of reasons. It would be instructive to run under a debugger, break on this routine, single-step through it, and determine which condition returns FALSE.

Are you able to run with the default X11 interface?

[RTimothyEdwards]

The The graphics display couldn't be correctly initialized should have been preceded by another error message explaining why the Cairo graphics couldn't be initialized. Are you getting such a message?

[RTimothyEdwards]

I think the answer to my question about the default X11 interface is that it fails, too, given that your "blank screen" image appears to claim that you started magic with magic -noconsole tut1 (meaning default graphics), and it said Using NULL graphics device. Again, were there any other error messages preceding the Using NULL graphics device?

Are you able to run with the default X11 interface?

Nope, running with -d X11 just gives a seg fault.

The The graphics display couldn't be correctly initialized should have been preceded by another error message explaining why the Cairo graphics couldn't be initialized. Are you getting such a message? Here is everything that displays when I use cairo.

$ magic -noconsole -d cairo

Use '-d NULL' if you don't need graphics.

Were there any other error messages preceding the Using NULL graphics device?

Nope, nothing suspicious, but here is the output:

Also, Is there some option to build magic with a more detailed log to see exactly whats going wrong?

[RTimothyEdwards]

Actually that helped a lot. Your first output has No suitable visual!, which narrows the problem down considerably. Running magic -d null or magic -dnull will not result in any errors, but also no graphics. This is a batch mode.

The No suitable visual! is printed as the result of this statement:

        grTCairoVisualInfo = XGetVisualInfo(grXdpy, VisualScreenMask,
                &grtemplate, &gritems);

. . . But I'm not sure what to make of that. It is the first true call to an X11 routine (DefaultScreen() a little bit before it is usually implemented as a macro, and probably would never return an error).
