I switched to texlive 2018 yesterday.

My Build-Environment: Win64, Texstudio, latexmk, lualatex, biber.

I tried to compile a test document - it worked fined using my old TL-17 and the new TL-18 installation.

Today I updated the TL-18 installation (using: tlmgr update --all). Now latexmk does not work anymore - I guess it crashes. I guess, because I don't get any output and I don't know how to further debug the problem:

Calling latexmk manually (e.g. latexmk --help) reports nothing: no help, no error message is printed. latexmk delivered with TL-17 still works fine - see this screenshot:

  • it works Ok in cygwin tl2018, could be an issue with the windows build, perhaps raise on the texlive list May 2, 2018 at 18:32
  • I also experienced this TeX Live 2018 bug, which appeared with the today update.

It seems latexmk.exe finds the wrong script.

What it should look for is




is found instead.

If you do not use make4ht, one workaround is to rename latexmk.lua (for example to latexmkX.lua).

UPDATE: The author of make4ht has renamed latexmk extension to latexmk_build in version 0.2b.
