Hi,
I believe there is an issue with 'lower-gexp'. Running the following
snippet to lower a G-Expression for "i686-linux" yields output that
references store paths built for x86_64. In this case, the Guile
interpreter used is an x86_64 binary.
#+BEGIN_SRC scheme
(define (display-exp exp)
(mlet* %store-monad ((lowered (lower-gexp exp
#:system "i686-linux"
#:target "i686-linux"))
(to-build -> (cons (lowered-gexp-guile lowered)
(lowered-gexp-inputs lowered)))
(_ (built-derivations to-build)))
(return (format #t "~a~%" (lowered-gexp-sexp lowered)))))
(with-store store
(run-with-store store
(display-exp #~(primitive-load #$(switch-system-program %system)))))
#+END_SRC

This doesn't seem to be an issue if '%current-system' is parameterized,
as in the following.
#+BEGIN_SRC scheme
(parameterize ((%current-system "i686-linux"))
(with-store store
(run-with-store store
(display-exp #~(primitive-load #$(switch-system-program %system))))))
#+END_SRC

Jakob

So the caller is responsible for doing the right thing here. In fact, if you do: (lower-gexp exp #:system whatever #:guile-for-build #f) it will automatically take care of computing the right Guile for this system. For consistency, I don’t think we should change the default, though. WDYT? Thanks, Ludo’. ^ permalink raw reply [flat|nested] 8+ messages in thread
