file fmutil

[Lars Madsen]

Only setting PATH in bashrc is a major source for problems on Linux. And it has been so for ever.

In most cases a PATH change in backrc will never be seen by a GUI programme that is opened via a menu or by double clicking a file. Basis env var 101.

On the other hand a gui that is started from a terminal will inherit the envs from the terminal and (if bash) thus also from bashrc.

Often the recommendation is to also have the PATH setting in dot profile (which is one of the start up scripts run at login, and thus at the top of the env hiraki)

But it of course also depend on the system at hand. THe above observations should be correct for Debian based systems.

(it is a very frequent error)

This may be an effect of the horribly baroque rules for which startup
scripts are sourced by shells (and /especially/ bash).

Where do you set the PATH you show above? In ~/.bashrc or in
~/.bash_profile or somewhere else?

Depending on your environment, distro etc. shells spawned indirectly
by GUI programs do not always get the benefit of these startup
scripts.

Maybe the next step in testing should be to run TeXstudio itself from
the command line (ie. from inside an xterm or such), instead of
clicking an icon or whatever.
