Mac mpf-mc Install Problem - Help please!

[Davey]

Hey,

Struggling to get mpf-mc installed on my mac. Initially caused my having 
Python 3.7 installed, I was able to get around that part by installing 3.6 
and then running the install using:

python3.6 -m pip install mpf-mc

This results in having an issue finding the include SDL.h.

/private/var/folders/tp/2tf55xqx1nz_c64bcwyj0y080000gn/T/pip-install-85odolj3/mpf-mc/mpfmc/core/audio/sound_file.c:524:10: fatal error: 'SDL.h' file not found

    #include "SDL.h"

             ^~~~~~~

    1 error generated.

    error: command 'gcc' failed with exit status 1

Other things I've tried:

brew install sdl

brew install sdl sdl_image sdl_mixer sdl_ttf portmidibrew install sdl2

brew link sdl

brew link sdl2

pip3 install setuptools --upgrade

Any help would be much appreciated!

[Davey]

I should also note that I've following the Mac installer instructions (a number of times) here:

http://docs.missionpinball.org/en/latest/install/mac.html

And install all the SDL frameworks into /Library/Framerworks

[Anthony van Winkle]

I remember encountering this issue before, but I can't say for certain how I solved it.

My first guess would be installing SDL directly from https://www.libsdl.org/download-2.0.php, choosing the Development library.

A search of my machine reveals two versions of SDL.h in  `/Library/Frameworks/SDL.framework/Versions/A/Headers/SDL.h` and  `/Library/Frameworks/SDL2.framework/Versions/A/Headers/SDL.h`

I'm not sure if the fact I'm using virtual environments instead of explicit python versioning makes any difference, but maybe that could get you in the right direction?

[Davey]

Finally got this working.

For some reason a lot of the SDL2 frameworks (SDL2_mixer, SDL2_image, GStreamer) didn't exist in the Frameworks folder, so when I redownloaded those from the installer docs, everything started working again.

Thanks the help! 

[Davey]

Anthony - if you wouldn't mind checking something for me please?

I'm now able to run one of the example games (yay) however the main MPF window is throwing some library warnings:

SDL2 is implemented in both /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/kivy/.dylibs/SDL2 and /Library/Frameworks/SDL2.framework/Versions/A/SDL2. One of the two will be used. Which one is undefined.

This is due to kivy having a number of duplicated dynamic libraries in the /.dylib folder. Would you be able to check you kivy install to see A) if it's in the same location as mind and B) if the SDL2 executable library exists on that folder?

Many thanks

Hi,

I have my pinball back and I am now in the process of updating my mac installations to the latest MPF.

While updating I now encounter exactly the same problem, after updating Kivy to 1.10.1.

Did you found a fix or workaround for this behavior?

If you found a solution it would be nice, if you can write a follow up here.

Thanks, Peter.

I'm not on a mac. Does this way work? https://kivy.org/doc/stable/installation/installation-osx.html#using-homebrew-with-pip. If not we can address this with the kivy dev team.

Hi Jan,

I tried building Kiwi without brew and followed the instructions to download the frameworks by hand, but then I get the dev version of Kivy which MPF then tells me that the requirements are not fulfilled. So at the moment I don't have a solution to this problem. It is quite annoying, because I can't see the Information in the main MPF window because of the error messages that appear.

I am out of time today, will continue to try and find a solution tomorrow.

Yours, Peter.  

[Peter Hauer]

Hello,

so I had to try it some more and I have now found a workaround which is quite obvious, but I was so focused on playing around with the Kivy Installation and the frameworks, that I did not thought about the easy way.

I can just simply start two terminal sessions and start mpf and mpf mc independently.

This does not solve the problem completely, but the warning then appears only in the terminal that launched mpf mc and not in the main window. mpf both is a bit more comfortable, but I don't get that problem with the frameworks solved at the moment.

Yours, Peter.

[jabdoa]

Hi Peter,

1. Can you post the complete output of your install?

2. Why do you think that the kivy installer gives you the dev version? https://pypi.org/project/Kivy/ is version 1.10.1 which is what we want. Can you post the output?

3. I don't understand why running "mpf game" and "mpf mc" works around your problem. Can you explain?

Jan

[jabdoa]

I tried it on travis. Looks like mpf-mc installs fine if you just run "brew install pkg-config sdl2 sdl2_image sdl2_ttf sdl2_mixer gstreamer" and "pip install Cython==0.26.1". See: https://travis-ci.org/missionpinball/mpf-mc/jobs/451139223. Maybe you need to uninstall the downloaded "framework.zip" before?

Jan

[Peter Hauer]

Hi,

thanks for the test and the reply. I will try the installation again, but will have to clean my installation. Perhaps something goes wrong because of the old files on my mac.

I have attached you a screenshot of the problem. The output of mpf mc goes into the main window, so that I can't read the information. If I start separately, then the output from mc goes into it's own terminal. Normally I would expect the warnings to be piped into the log file, but in this case that did not happen somehow.

Yours, Peter. 

[Peter Hauer]

Just spend lunch uninstalling everything and starting new installation.

So the problem is still there for me. If I delete the frameworks before I brew like you explained, then afterwards mpf-mc still has a dependency while loading and gives me this error:

Did I have to make the brewed gstreamer instance known to python myself somehow?

Hi Jan,

I have tried it now on my Windows7 machine and there I also get some warnings with gstreamer, so perhaps my original installation does influence with the update. I was on a 0.50 dev version before. The warnings on the windows machine are annoying, too because you have to confirm then when mc starts every time. So the Kivy-Update messes my installations up a bit I would say.

When I installed Kivy from scratch I got 1.11.x that is how I saw that. Just to answer your question from before.

I just got back and found the solution for the windows-problem:

libfreetype-6.dll is provided in share/gstreamer and share/sdl2 and in my case after the installation of kivy in my opinion it took the dll from the sdl2 path, where the additional dlls could not be found. after deleting the lib from the share/sdl2 path now everything works fine, as in my opinion now the dll in the gstreamer folder is used. So under windows7 I am up and running again. 

Now let's see if I can find the problem with the Mac-Installation. 

[Peter Hauer]

LOL!

I rebuild it like you did on Travis, but then I now got it the other way around.

This is really frustrating. I got rid of the Gstreamer dependencies, but now I have got the SDL2 doubled. I think I will have to start over again with building that, perhaps I made a mistake somewhere.

Perhaps on Travis you did not see this, because the installation is up and running, it is just the mpf main window that get's overwritten. So this behavior will not appear in the log-file.

Thanks, Peter.

[jabdoa]

Ah ok I understand the issue now. Thanks for debugging this further. We need to check with the kivy devs if this is a known problem. Does it work nonetheless? Or do you see any problems in mc (besides disturbing the mpf text ui)?

[Peter Hauer]

Hi,

I don't have any problems with mpf in this configuration. Haven't tested with my machine, but the development on mac works like normal.

I also found another workaround. If I use "mpf both -X" after the text appears in the UI of mpf, I can simply resize the window of mpf and it redraws itself. As this messages only appear at the start of mc this is a good workaround for me.

So perhaps we can implement that into mpf, so that a short time after mc is started it refreshes the ui once. Or we must see why the text output does not go into the log where it in my opinion should land.

That the frameworks exists double in system does not have another effect in my opinion. If I am the only one to experience this behavior or perhaps I am the only one using mac then just keep it like it is now, I can life with that now, that I have got a workaround.

Thanks for your help, again.

[jabdoa]

We can probably somehow suppress the log messages I guess. Have to look into it.
