Hello everyone:
I'd like to ask for help with the following:
I'm programming a Guile automation interface for GNU software compilation and
need to issue system calls with error escaping. I have package recipes, which
then issue mostly specific configure and make system calls and need to catch
errors, that mostly happen during configure and make runs.
Currently, I use the following to issue the configure and make recipes:
(use-modules (ice-9 popen)
(ice-9 rdelim))
(let* ((port (open-input-pipe command-string))
(str (read-line port)))
(close-pipe port)
str)
where command-string is the configure syntax or whatever...
The problem with this is, when configure fails for example due to an error, I
don't catch the error and next command gets executed... But I need to catch the
error and stop Guile from proceeding, so I see what happened.
How can I best do this?
Thanks a lot for any advice.
