Re: file fmutil

Karl, yes I am.

Running a test file from the command line all references are to 
/usr/local/texlive/2025/and friends

Here's what I get in TeXstudio's Messages tab after using it on the same 
test file:

Process started: pdflatex -synctex=1 -interaction=nonstopmode "gtest".tex

kpathsea: Running mktexfmt pdflatex.fmt

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/texlive/2025/bin/x86_64-linux 
Use of uninitialized value $TEXFMROOT in concatenation (.) or string at 
/usr/local/texlive/2025/bin/x86_64-linux/mktexfmt line 19. got: 
/usr/local/texlive/2025/bin/x86_64-linux/mktexfmt: kpsewhich 
-var-value=TEXMFROOT failed, aborting early. BEGIN failed--compilation 
aborted at /usr/local/texlive/2025/bin/x86_64-linux/mktexfmt line 27.

Process exited with error(s)


It seems that $TEXFMROOT is standing in the way.

I don't know why mktexfmt is being run either. The formats were made by 
tl during installation.

Thanks for the help,
Greg
