Hello! I'm getting this error while trying to compile latest guix master on one of my machines (fortunately, not my main one). I don't know why I'm hitting this error, since I'm not hitting it on my main machine. I'm upgrading from a few months back.
I spoke on irc and found that Ricardo had the same issue: <rekado> paroneayea: I also got this error trying to run “make” <rekado> paroneayea: it happens on my recording machine (x86_64) that hadn’t been updated in a while, but not on my laptop (also x86_64), which is updated regularly. Here's what I do. I start at the commit I was at (c2662820f359be19262cdd5d564e6a0dddc43281) and run "guix environment guix". Then I do a "git pull && make clean && make" and I get: ;;; Failed to autoload cairo-image-surface-create in (cairo): ;;; ERROR: missing interface for module (cairo) ;;; Failed to autoload cairo-image-surface-create in (cairo): ;;; ERROR: missing interface for module (cairo) ;;; Failed to autoload rsvg-handle-new-from-file in (rsvg): ;;; ERROR: missing interface for module (rsvg) ;;; Failed to autoload cairo-image-surface-create in (cairo): ;;; ERROR: missing interface for module (cairo) ;;; Failed to autoload rsvg-handle-new-from-file in (rsvg): ;;; ERROR: missing interface for module (rsvg) ;;; Failed to autoload cairo-image-surface-create in (cairo): ;;; ERROR: missing interface for module (cairo) LOAD (gnu build vm) LOAD (gnu tests) LOAD (gnu tests base) LOAD (gnu tests nfs) LOAD (gnu tests install) warning: 'waitpid' -1 failed unexpectedly: No child processes Backtrace: In ice-9/boot-9.scm: 3088: 19 [#<procedure 4226c30 at ice-9/boot-9.scm:3069:17 ()>] In unknown file: ?: 18 [primitive-load-path "gnu/tests/install" ...] In ice-9/eval.scm: 453: 17 [eval # ()] 411: 16 [eval # #] 387: 15 [eval # #] 373: 14 [run-install # #] 387: 13 [eval # #] 387: 12 [eval # #] 387: 11 [eval # #] 411: 10 [eval # #] In srfi/srfi-1.scm: 573: 9 [map #<procedure 360a6c0 at ice-9/eval.scm:416:20 (a)> (# # # # ...)] In ice-9/eval.scm: 387: 8 [eval # #] 411: 7 [eval # #] 411: 6 [eval # #] 387: 5 [eval # #] In unknown file: ?: 4 [force #<promise #<procedure 5bbf150 at ice-9/eval.scm:416:20 ()>>] In ice-9/eval.scm: 411: 3 [eval # #] 411: 2 [eval # #] In ice-9/popen.scm: 98: 1 [close-process #<closed: file 0> 28701] In unknown file: ?: 0 [waitpid 28701 #<undefined>] ERROR: In procedure waitpid: ERROR: In procedure waitpid: No child processes make[2]: *** [Makefile:4929: make-go] Error 1 make[2]: Leaving directory '/home/cwebber/src/guix' make[1]: *** [Makefile:4072: all-recursive] Error 1 make[1]: Leaving directory '/home/cwebber/src/guix' make: *** [Makefile:2728: all] Error 2 This is on commit 21abf092a49f0ce80cbfff5cccabb7dbf53abf96 If instead I switch back to c2662820f359be19262cdd5d564e6a0dddc43281 I can compile Guix again. I did a git-bisect to find what commit was breaking things. According to git-bisect, the perpetrator is: 63302a4e55241a41eab4c21d7af9fbd0d5817459 is the first bad commit commit 63302a4e55241a41eab4c21d7af9fbd0d5817459 Author: Ludovic Courtès <l...@gnu.org> Date: Mon Feb 6 23:47:09 2017 +0100 Add (gnu build shepherd). * gnu/build/shepherd.scm: New file. * gnu/local.mk (GNU_SYSTEM_MODULES): Add it. :040000 040000 7a07b30ebec719aca2fba4c2776f7152e669a1ee 63eb6bc3fa184fc42c3d469d594fc056f16b7892 M gnu bisect run success I've confirmed this by double-checking that I can build the commit before but not this commit. I don't really know why this fails, but it looks like it's somehow triggering a remote process in some way related to tests and shepherd... which is confusing, because I don't think this happening during tests. - Chris
