[BUG] latex run fails for ob-latex with imagemagick options

[BUG] latex run fails for ob-latex with imagemagick options

[Robert Klein]

[-- Attachment #1: Type: text/plain, Size: 1458 bytes --]

Hi,

when trying to create an image by the attached code (test.org), the LaTeX run
fails because the interim code contains both pdflatex and luatex
specific usepackage commands fontspec, inputenc, and fontenc).


The code is supposed to export a LaTeX-tikz to png using the imagemagick header options (as described in the ob-latex documentation of worg).  I get no error when I remove the imagemagick header line (but also unusable output).

According to my bisect the first commit this happens is:

    org-latex-default-packages-alist: Refine packages for font management

    * lisp/org.el (org-latex-default-packages-alist): Change to refine
    font management depending on the latex compiler.

    Differentiate between pdflatex and lualatex/xetex
    packages for font management.  lualatex/xetex should use
    fontspec instead of fontenc/inputenc.  When using
    fontspec, you need to load amsmath before fontspec
    and you don't need amssymb.

I also attached the interim LaTeX file, the log file of the LaTeX run and the contents of the *Org PDF LaTeX Output* buffer.


Thanks for any help.

Best regards
Robert
