test1.tex:17: ==> Fatal error occurred, no output PDF file produced!


Latex does not tell me on its log which command is not defined. It only says Undefined control sequence, which is very much useless.



How can I make latex tell me exactly which command he is not finding defined?



Only after a lot of trying, I figured out that the ifpackagewith does not check whether the package is loaded. It only checks whether there is some option on the package name queue.



Then, a fixed version is:



makeatletter
@ifpackageloaded{babel}{@ifpackagewith{babel}{english}{message{English YES!^^J}}{message{English NO!^^J}}}{}
@ifpackageloaded{babel}{@ifpackagewith{babel}{brazil}{message{Brazil YES!^^J}}{message{Brazil NO!^^J}}}{}
@ifpackageloaded{babel}{@ifpackagewith{babel}{turkish}{message{Turkish YES!^^J}}{message{Turkish NO!^^J}}}{}

@ifpackageloaded{babel}{@ifpackagewith{babel}{brazil}{addtocaptionsbrazil{renewcommand{lstlistingname}{Código}}}{}}{}
@ifpackageloaded{babel}{@ifpackagewith{babel}{english}{addtocaptionsenglish{renewcommand{lstlistingname}{Code}}}{}}{}
makeatother


Or just load the babel package with RequirePackage{babel}.





Now, forgetting about the fix, which is load babel or use @ifpackageloaded. Why latex does not tell me which command was undefined from the beginning???



If I remove the -latexoption=-halt-on-error, then, latex tells me the command lstlistingname is undefined, but that is the WRONG command. The command which is undefined is addtocaptions from babel package, which was not loaded.



See here the output from latex:



'latexmk.exe' -cd -f -pdf -interaction=nonstopmode -synctex=1 '--output-directory=cache' -latexoption=-file-line-error -latexoption=--max-print-line=10000 test1.tex



xmemoirmempatch.sty)) English YES!
Brazil NO!
Turkish NO!
test1.tex:15: Undefined control sequence
test1.tex:15: Undefined control sequence

test1.tex:15: LaTeX Error: lstlistingname undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help


If I remove the lstlistingname from the input program like this:



makeatletter
@ifpackagewith{babel}{english}{message{English YES!^^J}}{message{English NO!^^J}}
@ifpackagewith{babel}{brazil}{message{Brazil YES!^^J}}{message{Brazil NO!^^J}}

@ifpackagewith{babel}{brazil}{addtocaptionsbrazil{}}{}
@ifpackagewith{babel}{english}{addtocaptionsenglish{}}{}
makeatother


And run back latex again, without the -interaction=nonstopmode and -latexoption=-halt-on-error, then, latex tells me absolutely nothing about which command is undefined!

Why latex does not tell which command is not defined? Does it hurt him? Is he afraid it is too much information and I cannot handle it by myself???



Is there some fix I can apply to latex, so it starts telling me which commands is not defined when there is some error?

      test1.tex:17: ==> Fatal error occurred, no output PDF file produced!


      Latex does not tell me on its log which command is not defined. It only says Undefined control sequence, which is very much useless.



      How can I make latex tell me exactly which command he is not finding defined?



      Only after a lot of trying, I figured out that the ifpackagewith does not check whether the package is loaded. It only checks whether there is some option on the package name queue.



      Then, a fixed version is:



      makeatletter
      @ifpackageloaded{babel}{@ifpackagewith{babel}{english}{message{English YES!^^J}}{message{English NO!^^J}}}{}
      @ifpackageloaded{babel}{@ifpackagewith{babel}{brazil}{message{Brazil YES!^^J}}{message{Brazil NO!^^J}}}{}
      @ifpackageloaded{babel}{@ifpackagewith{babel}{turkish}{message{Turkish YES!^^J}}{message{Turkish NO!^^J}}}{}

      @ifpackageloaded{babel}{@ifpackagewith{babel}{brazil}{addtocaptionsbrazil{renewcommand{lstlistingname}{Código}}}{}}{}
      @ifpackageloaded{babel}{@ifpackagewith{babel}{english}{addtocaptionsenglish{renewcommand{lstlistingname}{Code}}}{}}{}
      makeatother


      Or just load the babel package with RequirePackage{babel}.





      Now, forgetting about the fix, which is load babel or use @ifpackageloaded. Why latex does not tell me which command was undefined from the beginning???



      If I remove the -latexoption=-halt-on-error, then, latex tells me the command lstlistingname is undefined, but that is the WRONG command. The command which is undefined is addtocaptions from babel package, which was not loaded.



      See here the output from latex:



      'latexmk.exe' -cd -f -pdf -interaction=nonstopmode -synctex=1 '--output-directory=cache' -latexoption=-file-line-error -latexoption=--max-print-line=10000 test1.tex

      test1.tex:15: LaTeX Error: lstlistingname undefined.

      See the LaTeX manual or LaTeX Companion for explanation.
      Type H <return> for immediate help


      If I remove the lstlistingname from the input program like this:



      makeatletter

      @ifpackagewith{babel}{brazil}{message{Brazil YES!^^J}}{message{Brazil NO!^^J}}

      @ifpackagewith{babel}{english}{addtocaptionsenglish{}}{}
      makeatother


      And run back latex again, without the -interaction=nonstopmode and -latexoption=-halt-on-error, then, latex tells me absolutely nothing about which command is undefined!

      Why latex does not tell which command is not defined? Does it hurt him? Is he afraid it is too much information and I cannot handle it by myself???



      Is there some fix I can apply to latex, so it starts telling me which commands is not defined when there is some error?
