Here is what I did: First of all I created the wrapper file, and put it in HOME\bin, which I had already created following your instructions. Then I’ve run $ cat $HOME/bin/maxima in the terminal window, and got the two lines of the new “wrapper” file. Then put both ~/bin and HOME/bin in the LyX path for good measure, reconfigured LyX, closed Lyx and relaunched it, and again, it does not work. So I thought maybe I should also have run the last two of the three other lines of code to be run in the terminal. Did that, but as you can see from the attachment after running that command I do not get a “$” sign, but a “>” as terminal prompt. Maybe this is the problem? Thanks for your patience! No problem. Simply type the 2 lines, cat is awaiting input. To end the input you have to enter EOF, probably it is control+D. Kornel thanks Kornel (and Stephan), but now the result is that the maxima wrapper has been overwritten by empty lines! So just to recap what I’ve done: 1. created the wrapper file, called it maxima, put it in HOME/bin, and checked it is there with the correct content by running the command “$ cat $HOME/bin/maxima” (no quotes) in the terminal window; I can also see the file in finder 2. run the three commands in the terminal window, where after the second line I had to use ctrl D to signal end of file as a result, the “maxima” file has become an empty file (indeed, running “$ cat $HOME/bin/maxima” in the terminal window returns empty lines. No change in behaviour in Lyx. If it helps, I have also Maple and Mathematica installed on my machine, but no luck invoking them from LyX either. screenshot of terminal window is attached in case it is of any help. Above all, thanks for taking the time with this. paola <Screen Shot 2016-10-18 at 17.44.15.png> Hi Paola, I tried to be as verbose as I can - but it was too terse, sorry. Two points: 1. The dollar sign in front of my command line text shouldn’t be typed. It’s usual to mark text input as terminal input. 2. The EOF marker is an arbitrary text and should have been typed as given. I’ll attach a screen shot of a my terminal session to prepared the wrapper script. Finally the correct PATH extension in LyX settings is important. Either it should be „$HOME/bin“ or „~/bin“ - having both does not harm but it slightly reduces the startup speed of every external script. Regards, Stephan <Bildschirmfoto 2016-10-18 um 22.17.21.png> Dear Stephan, thanks so much for the time you are taking on this, and apologies for being slow! I have tried following exactly what you did, but there seems to be a problem when I get to “which maxima” - I get an empty line. On the other hand, the cat $HOME/bin/maxima does return the contents of the file, and I do see a newly created maxima file in the “bin” folder (in finder) - maybe my system is missing some other component? Again, many thanks, Paola p.s. screenshot attached <Screen Shot 2016-10-19 at 07.40.07.png> Dear Paola, no problem, we’re almost there. Sorry, I forgot to adjust the PATH setting in terminal. I have $HOME/bin already in PATH in terminal. This is not standard, obviously - so let’s add it for the test :) This is the equivalent of adding $HOME/bin to LyX PATH settings. See the screenshot. Regards, Stephan Oops, the screenshot… the blue text is my keyboard input. <Bildschirmfoto 2016-10-19 um 09.45.42.png> YAY!!! it works Stephan, thank you ever so much, you have been so very patient, never been so happy to discover that 3+2=5 :-) Presumably I would have to repeat the same procedure to create wrappers for mathematica and maple? e.g.: #!/bin/sh /Applications/Mathematica.app/Contents/MacOS/MathKernel "$@" for mathematica and #!/bin/sh /Applications/Maple 18/Maple 18.app/Contents/MacOS/Maple 18 "$@" Again, a million thanks! Paola
