Hi Folks, I'm having some trouble packaging Jitsi (a VoIP client written in Java). The attached patch adds the package "jitsi", which completes the "build" phase, but fails as below. Ignoring for now that Jitsi is bundling a whole lot of dependencies, can someone help me understand what’s going on: phase `build' succeeded after 45.3 seconds starting phase `check' test suite not run phase `check' succeeded after 0.0 seconds starting phase `strip-jar-timestamps' find-files: /gnu/store/kz7kwgm25xk83fc69immm80dazv9gb6x-jitsi-2.10: No such file or directory phase `strip-jar-timestamps' succeeded after 0.0 seconds starting phase `patch-shebangs' phase `patch-shebangs' succeeded after 0.0 seconds starting phase `strip' phase `strip' succeeded after 0.0 seconds starting phase `validate-runpath' phase `validate-runpath' succeeded after 0.0 seconds starting phase `validate-documentation-location' phase `validate-documentation-location' succeeded after 0.0 seconds starting phase `delete-info-dir-file' phase `delete-info-dir-file' succeeded after 0.0 seconds starting phase `patch-dot-desktop-files' phase `patch-dot-desktop-files' succeeded after 0.0 seconds starting phase `reset-gzip-timestamps' find-files: /gnu/store/kz7kwgm25xk83fc69immm80dazv9gb6x-jitsi-2.10: No such file or directory phase `reset-gzip-timestamps' succeeded after 0.0 seconds starting phase `compress-documentation' phase `compress-documentation' succeeded after 0.0 seconds builder for `/gnu/store/hxpb6xvx324d9i9kxc7ywfwwaz3zgs4z-jitsi-2.10.drv' failed to produce output path `/gnu/store/kz7kwgm25xk83fc69immm80dazv9gb6x-jitsi-2.10' @ build-failed /gnu/store/hxpb6xvx324d9i9kxc7ywfwwaz3zgs4z-jitsi-2.10.drv - 1 builder for `/gnu/store/hxpb6xvx324d9i9kxc7ywfwwaz3zgs4z-jitsi-2.10.drv' failed to produce output path `/gnu/store/kz7kwgm25xk83fc69immm80dazv9gb6x-jitsi-2.10' note: keeping build directory `/tmp/guix-build-jitsi-2.10.drv-0' guix build: error: build failed: build of `/gnu/store/hxpb6xvx324d9i9kxc7ywfwwaz3zgs4z-jitsi-2.10.drv' failed Regards, Ben -- Ben Sturmfels Sturm - Software Engineering www.sturm.com.au (03) 9024 2467
