TeX Live and MacTeX ⇒ Texdoc not found

[hamaryns]

HI all,

I installed a small version of TL. Then later I did tlmgr install texdoc. Texdoc was installed, but still isn’t found in the PATH. What am I missing? (Same happens with texdoctk.)

Linux Mint 19, 64 bit

Cheers, H.

Hi,
tlmgr installs binaries under $TEXMFROOT/bin/<architecture>, AFAIUI.
For $TEXMFROOT you can ask kpsewhich (assuming it's installed):

Code: Select all

kpsewhich -var-value TEXMFROOT

<architecture> should be `x86_64-linux' on your system.
If tlmgr's sys_bin option is set, it will also attempt to create a symbolic link in the directory specified (which is usually part of a user's $PATH variable, like /usr/local/bin).
Then again, if this sys_bin option is not set, the binaries directory should be part of the $PATH variable..unless you have to prepend the path to pdflatex & friends to begin with.
What does

Code: Select all

which pdflatex

tell you?

BTW: if you're unable to open the documentation to package x, maybe you don't have its documentation installed...
What is the output of

Code: Select all

tlmgr option docfiles

on your system?

Hi,

Thanks for the explanation. Indeed, there is texdoc(tk) in /usr/local/texlive/2018/bin/x86_64-linux/, but not in /usr/local/bin (pdflatex etc. are there indeed and work).

tlmgr option show tells me docfiles are installed (1), and sys_bin is set to /usr/local/bin. So somehow it knows where to put the symlinks, but it doesn’t.

Ok, reading a bit further in man tlmgr, the only thing I had to do was:

Code: Select all

$ sudo tlmgr path add

I was in the (naive?) supposition that installing a binary would trigger that automatically. Why not? Can I set that?

Thanks.

I dunno...perhaps one of TL's mailing lists would be more suited to answer that particular question.
OTOH, if you already know your problem's caused by a missing symbolic link, you could either create such a link yourself or include `kpsewhich -var-value TEXMFROOT`/bin/`tlmgr --print-arch` to your $PATH environment variable, omitting the need for such a symbolic link altogether.
