texliveonfly is a python script, it can install missing packages automatically while compiling. I had to change the script a little bit for it to work from cmd.exe, I attached it. So if I type the command ( "C:/texlive/2019/texmf-dist/scripts/texliveonfly/texliveonfly.py" file.tex ) in cmd running in the folder where file.tex is located, and the file uses not installed packages, the script installs those and then compiles latex file. I am currently trying to get this script working with LyX, I set it up in converters latex(pdflatex) -> PDF (pdflatex), i typed it ""C:/texlive/2019/texmf-dist/scripts/texliveonfly/texliveonfly.py" $$i" without any additional flags. This unfortunately does not work, i get error "support\Systemcall.cpp (291): Systemcall: '"C:/texlive/2019/texmf-dist/scripts/texliveonfly/texliveonfly.py" "tlof.tex"' finished with exit code 1" and a message box that an error occurred while executing the converter command. Strange thing is, that if the lyx file does not use any not installed packages, it works, I mean the file compiles. I have tried to debug it, found the line "process_->start(toqstr(latexEnvCmdPrefix(path, lpath)) + cmd_);" (Systemcall.cpp, line 390) and the QString passed to start() there looks alright. I have also copied it to another c++ project, just an epty "Hello World" like console project, where I execute the same string with QProcess and it works there. Any Idea why this isn't working with lyx?
