All of them are using org-mode from elpa. For about 10 of them, they are unable to toggle the latex-overlays; instead of getting the equations, they get empty gray boxes with an error that the png file was not created. Oddly enough, they can export to PDF just fine. I have also checked that they have LaTeX (TeXLive) installed, and it appears it is. I am able to convert tex files to dvi, and then use dvipng to make a png image. But for some reason, the toggle-latex-overlay function does not work for them. I am at a loss to figure out what the issue is. These are Windows laptops that were preconfigured by the department. Almost all of them work fine, except for this small number I cannot figure out. Any ideas? Thanks, -- ----------------------------------- John Kitchin http://kitchingroup.cheme.cmu.edu ^ permalink raw reply [flat|nested] 7+ messages in thread

Thanks, I would edebug-defun the function org-create-formula-image and step through it to make sure that it goes the way you want (are you sure you are using the dvipng method on these machines? maybe you are using the imagemagick method but the program has not been installed? Check the value of org-latex-create-formula-image-program). While you are stepping you can also check the variables in the function and see e.g. what the output file name is. If that goes OK, then I would edebug-defun org-create-formula-image-with-dvipng next and check the latex input file it produces. Make sure that things like minted which require --shell-escape are *not* included in that input file: it's processed by a hard-wired call to latex (without --shell-escape) , so minted will cause a failure. If that is the case, check org-latex-packages-alist and make sure that minted's snippet-flag is nil. HTH, Nick ^ permalink raw reply [flat|nested] 7+ messages in thread

The issue is in the function org-preview-latex-fragment. At the end of the function, where it calls org-format-latex, the default-directory variable that is used in the function call has a value of "c:/Users/YUYUA~1/AppData/Local/Temp/ltxpng/mole-balance" The YUYUA~1 is causing the problem. I do not understand why the full path, "c:/Users/Yuyu Yao/AppData/Local/Temp" is not showing up here. When I examine the default-directory variable in a buffer in that directory, that is what comes up. It is only inside the org function it gets chomped to what looks like an old DOS format. Anyway, latex cannot handle that path, so no dvi is produced, and no image. otherwise the latex file is produced, and it compiles fine with the full path. Any ideas on how to fix that?

I have a workaround solution, which is to set the temproary-file-directory variable this way: (setq temporary-file-directory (expand-file-name "~/../Local/Temp")) which gives it a full path. It is pretty odd. There are about 50 students with nominally the same computers in this class, but this issue seems to only affect about 20% of them!

I don't think it would work. the Space is also not the issue, as it affects some users with no spaces. This is for some reason, like a partial dos 8.3 filename (http://en.wikipedia.org/wiki/8.3_filename). I still do not know why it happens, but setting the temporary-file-directory in the init.el solves the problem, e.g.: (setq temporary-file-directory "c:/some/full/path") > >> I do not understand why the full path, "c:/Users/Yuyu >> Yao/AppData/Local/Temp" is not showing up here.
