Flymake and tramp

[Jonathan Groll]

When I open a ruby buffer using tramp's ssh method I get a popup
stating:

Flymake: Configuration error has occured while running (ruby -c
buffername_flymake.rb). Flymake will be switched OFF

("buffername.rb" in the above will be the name of the file I'm opening)

I assume I need to supply tramp with hints as to where to find ruby?
Or flymake.el? But, the message implies a configuration error, is
there a tramp log perhaps that will show the error? Customizing
flymake-log-level to 3 results in the following in *Messages* which
doesn't say all that much more:

switched OFF Flymake mode for buffer blogg.rb due to fatal status
CFGERR, warning Configuration error has occured while running (ruby -c
blogg_flymake.rb)

I wonder too why it appends _flymake to the filename, such a file does not exist!

If I ssh into the same host and open the same buffer in emacs -nw, flymake
works fine and stays on.

Jonathan Groll.

Mark set

A temp-inplace file is created by flymake, reading the above it seems
that this is a path issue, or is that wrong? I tried adding
/var/www/blog to $PATH in ~/.shrc and ~/.bashrc on the remote host,
and also customized "Tramp Remote Path" but none of those worked
yet...

Which Emacs and Tramp versions are you using?

In `flymake-start-syntax-check-process' of flymake.el, `start-process'
is called. This does not work on remote hosts. Instead of,
`start-file-process' shall be used.

It works! Do I need to open a bug report to have this permanently
fixed, or do you perhaps have commit rights to fix this one?

Many thanks,
Jonathan

I have commit rights. However, I'm not so familar with flymake.el; it
might be better if somebody else reviews the proposed change.

Furthermore, GNU Emacs 23 is frozen while in pretest phase. So it might
be, that the patch must be postponed until after the release of 23.1.

For these reasons I prefer, if you could write a bug report.
