Remote shell (tramp) and login script

Question

When I open a file via tramp on a remote machine and then start a shell with M-x shell I get an infinite loop because of my .cshrc file.

I want to use a newer gcc version in CentOS so I have:

set X="`gcc -dumpversion`"
if ($x != "4.8.2") then
  scl enable devtoolset-2 tcsh
endif

It seems that inside emacs the gcc -dumpversion always gives 4.4.7 and the scl enable is run an infinite number of times. (The scl enable starts a new shell.)

When I ssh into this machine it starts fine with gcc 4.8.2.

Do I have to use any settings to get the shell in emacs tramp to work?

Answer 1

I'm not sure that your setup will work. You use csh, but Tramp supports only POSIX-like shells. Settings like $PATH, you might have in your .login or .cshrc, won't be applied.

Maybe you play with tramp-remote-path and alike, in order to get better results.
