I have org file with C source block. I work with file on Windows PC.
I have linux machine, which is accessible through Putty. For reasons, i
want to evaluate C code blocks there (mostly because it has gcc).
Here is relevant fragment of my org file:
> #+PROPERTY: header-args :noweb yes :results verbatim :dir /pscp:tcl:/home/tc
> :flags -std=c99

> Ok, time for something more interesting.

However, when i evaluate source block, i get the following error:
> Spawning child process: invalid argument
I have tried to debug the issue. Error is produced by call to
> (write-region start end input-file)
in function org-babel--shell-command-on-region. This supposedly creates
on remote machine file containing user input (actually,
empty). Evaluation does not go to the invocation of compiler command
line, sadly.
How can that be fixed?
