file fmutil

[Greg Bennett]

In trying to get TeXstudio to recognize my texlive(2025) installation I 
continually run into
this error:

kpathsea: Running mktexfmt pdflatex.fmt

/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 25.

Process exited with error(s)

This message comes from /usr/local/texlive/2025/bin/x86_64-linux/fmutil

I am wondering whether my version of that file is corrupt. Could you 
please send me your

installation's version of this file so I can compare ?

I don't speak perl, but my sense of the first few lines (from which the 
error comes) is that if the value of

$TEXMFROOT does not match what kpsewhich -var-value=TEXMFROOT returns, 
then die (which it does).

I have run export TEXMFROOT=/usr/local/texlive/2025 -- the value 
returned by that kpsewhich clause,

but this has had no effect.

Thanks
