From Ceramic:bundle got uiop/run-program:subprocess-error does not find my component (and not showing much)

Question

I want to build an application into a bundle with Ceramic. I can run the app with it. The error arises with:

(ceramic:bundle :WEBLOCKS-TODOMVC :bundle-pathname #p"build/todomvc.tar")

it runs…

Ceramic: Compiling app...
Launch:
"/usr/local/bin/sbcl" --noinform --no-userinit --no-sysinit
 --load "/home/vince/quicklisp/setup.lisp"

                   (declare (ignore h))
                   (uiop:print-condition-backtrace c)
                   (uiop:quit -1)))"
 --eval "(asdf:load-system :WEBLOCKS-TODOMVC)"
 --eval "(setf uiop:*image-entry-point*

                          #+sb-core-compression t)"

and crashes:

 exited with error code 255
   [Condition of type UIOP/RUN-PROGRAM:SUBPROCESS-ERROR]

However, the log error, the backtrace don't contain much information at all. Is there a way to ask for more ?

I did a mkdir build/ to be sure.

Given coredump's answer:

I went up in the source (with M-.) from ceramic:bundle to find the call to uiop:run-process, which I added the two parameters and wrapped around a multiple-value-bind:

(multiple-value-bind (zero one two)
    (uiop:run-program command
                  :output *standard-output*
                  :error :output
                  :error-output :lines
                  :ignore-error-status t)
  (format t "------------ printing error messages:")
  (log:info zero)
  (log:info one)
  (log:info two))))

and running the build command again:

so it seems that the build can not find my component "weblocks-todomvc". Which I find surprising because my .asdf file compiles correctly, I can run a Ceramic window,…

Given the comments under this question, I make trivial-build load my package by adding (format nil "(load #p\"/home/vince/projets/weblocks-todomvc/weblocks-todomvc.asd/\"") in trivial-build:load-and-build-code and I get a different stacktrace:

Answer 1

You need to:

• pass :ignore-error-status t
• define how you want to retrieve the error messages with :error-output (e.g. :lines)

Then, run-program won't signal an error but you have to check the error status (third value), and print/inspect the error message (second value).

RUN-PROGRAM returns 3 values:
0- the result of the OUTPUT slurping if any, or NIL
1- the result of the ERROR-OUTPUT slurping if any, or NIL
2- either 0 if the subprocess exited with success status,
or an indication of failure via the EXIT-CODE of the process
