grafed-gui graphs.json >&/dev/null

[Arvendui]

When, following the tutorial I try to display the Feynman rules, auto rules = toyModel.getFeynmanRules();Show(rules);I get grafed-gui graphs.json >&/dev/null

[docbrown1955]

Could you tell me what happens when you launch

grafed-gui graphs.json >/dev/null 2>&1 & sleep 1

GRAFED should launch and display no output in the terminal, And you should get back the command line after a second without closing the window.

If this works I will change the behavior (for now the command only works on Linux apparently, the one above should work also on MacOS)

Do you have grafed-gui in the path ? /usr/local/bin should be in the $PATH variable

Do you have grafed-gui in the path ? /usr/local/bin should be in the $PATH variable

I am a bit confused by what should I check....

[docbrown1955]

If you do

echo $PATH

the /usr/local/bin should appear

[docbrown1955]

Otherwise you have to

export PATH=$PATH:/usr/local/bin

(and copy the line in your ${HOME}/.bashrc file for all the next times

[Arvendui]

If you do

echo $PATH

the /usr/local/bin should appear

I get /opt/local/bin:/opt/local/sbin:/opt/anaconda3/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.8/bin:/Library/Frameworks/Python.framework/Versions/3.8/bin:/Applications/anaconda3/bin:/Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/Library/Apple/usr/bin so it seems that I do?

[docbrown1955]

Yes. And is there the /usr/local/bin/grafed-gui executable ? If yes just try to launch it

/usr/local/bin/grafed-gui graphs.json

[Arvendui]

/usr/local/bin/grafed-gui graphs.json

there is, and when I run the command you suggested, I get dyld[79130]: Library not loaded: @rpath/libQt5PrintSupport.5.dylib Referenced from: /usr/local/bin/grafed-gui Reason: tried: '/usr/local/lib/libQt5PrintSupport.5.dylib' (no such file), '/usr/lib/libQt5PrintSupport.5.dylib' (no such file) Abort trap: 6

which again seems an issue of Qt5

[docbrown1955]

Ok I see. You should locate these Qt libraries and add their path to the DYLD_LIBRARY_PATH (with a export as for the other variables, and put this in the .bashrc also)

[docbrown1955]

When you executed the example, did the program continued to run after Show() ?

[Arvendui]

When you executed the example, did the program continued to run after Show() ?

Yes it does

[docbrown1955]

When you executed the example, did the program continued to run after Show() ?

Yes it does

Ok so at least it is not blocking, you just cannot see the graphs.

[Arvendui]

DYLD_LIBRARY_PATH

echo $DYLD_LIBRARY_PATH does not return any path

[Arvendui]

Yes it does

exactly

[docbrown1955]

Maybe you can see this issue that addresses the same problem

[Arvendui]

running locate libQt5PrintSupport (which is the library it cannot find), returns paths /opt/anaconda3/lib/libQt5PrintSupport.5.9.7.dylib. How can I add this path? (or also /usr/local/anaconda3/lib/libQt5PrintSupport.5.dylib)

[docbrown1955]

You can try

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/opt/anaconda3/lib/

[Arvendui]

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/usr/local/anaconda3/lib/ got the job done

[docbrown1955]

Perfect!
