Package: imagemagick Version: 8:6.6.0.4-3 Severity: normal I have seen this too. I am building on an 8 core xeon. If I use DEB_BUILD_OPTIONS=parallel=8, then it almost never fails. If I use DEB_BUILD_OPTIONS=parallel=16 then it almost always fails.
So there is some race condition in the imagemagick makefiles that makes it not safe to build in parallel. The race is only triggered with enough parallelism it seems. It seems it results in something trying to use libMagick++.so before it is actually fully written. I can provide logs from both a working parallel=8 and a broken parallel=16 run if that would help. It fails on squeeze, wheezy and sid in the same way. This is absolutely a problem in imagemagick's makefiles when doing parallel building in my opinion. Having found other similar reports from gentoo users and others where it failed to build with more parallelism in the past seems to agree with that. The simple fix of course is to not use parallel building. A real fix would involve getting upstreams makefiles fixed. -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/1 CPU core) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages imagemagick depends on: ii libbz2-1.0 1.0.5-6 high-quality block-sorting file co ii libc6 2.11.2-12 Embedded GNU C Library: Shared lib ii libfontconfig1 2.8.0-2.1 generic font configuration library ii libfreetype6 2.4.4-1 FreeType 2 font engine, shared lib ii libglib2.0-0 2.28.1-1+b1 The GLib library of C routines ii libgomp1 4.5.2-4 GCC OpenMP (GOMP) support library ii libice6 2:1.0.7-1 X11 Inter-Client Exchange library ii libjpeg62 6b1-1 The Independent JPEG Group's JPEG ii liblcms1 1.18.dfsg-1.2+b3 Color management library ii liblqr-1-0 0.4.1-1 converts plain array images into m ii libltdl7 2.2.6b-2 A system independent dlopen wrappe ii libmagickcore3 8:6.6.0.4-3 low-level image manipulation libra ii libmagickwand3 8:6.6.0.4-3 image manipulation library ii libsm6 2:1.2.0-1 X11 Session Management library ii libtiff4 3.9.4-5 Tag Image File Format (TIFF) libra ii libx11-6 2:1.4.1-5 X11 client-side library ii libxext6 2:1.2.0-2 X11 miscellaneous extension librar ii libxt6 1:1.0.9-2 X11 toolkit intrinsics library ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages imagemagick recommends: ii ghostscript 9.01~dfsg-2 interpreter for the PostScript lan ii libmagickcore3-extra 8:6.6.0.4-3 low-level image manipulation libra ii netpbm 2:10.0-12.2+b1 Graphics conversion tools between ii ufraw-batch 0.18-1 batch importer for raw camera imag Versions of packages imagemagick suggests: pn autotrace <none> (no description available) ii cups-bsd [lpr] 1.4.6-1 Common UNIX Printing System(tm) - ii curl 7.21.3-1 Get a file from an HTTP, HTTPS or pn enscript <none> (no description available) pn ffmpeg <none> (no description available) ii gimp 2.6.11-1 The GNU Image Manipulation Program ii gnuplot 4.4.0-1.1 A command-line driven interactive pn grads <none> (no description available) ii groff-base 1.21-4 GNU troff text-formatting system ( pn hp2xx <none> (no description available) pn html2ps <none> (no description available) pn imagemagick-do <none> (no description available) ii libwmf-bin 0.2.8.4-6.1+b1 Windows metafile conversion tools ii mplayer 3:1.0~rc4+svn20110225-0.0 The Ultimate Movie Player For Linu pn povray <none> (no description available) pn radiance <none> (no description available) ii sane-utils 1.0.22-1 API library for scanners -- utilit ii texlive-binari 2009-8 Binaries for TeX Live pn transfig <none> (no description available) ii xdg-utils 1.1.0~rc1-2 desktop integration utilities from -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
