From: Peter Korsgaard Date: Mon, 6 Feb 2017 17:02:55 +0000 (+0100) Subject: imagemagick: fix build of png support when jpeg support is disabled X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6f8088fdd56384fb9dc61ca31a0c1772acfde93;p=buildroot.git imagemagick: fix build of png support when jpeg support is disabled Fixes: http://autobuild.buildroot.net/results/d20/d20eecec8e7b947759185f77a6c8e610dd7393f3/ http://autobuild.buildroot.net/results/ee1/ee15efa8ae3f95244980810155ff7ba9f885a59d/ http://autobuild.buildroot.net/results/aa8/aa80f2fd4c7dd884ea8a1b55ad15a40c7bf40501/ http://autobuild.buildroot.net/results/9aa/9aaa044f78115d7f599ea09669c0d6bface5633e/ This combination is broken since 7.0.4-6. Since commit a9e228f8ac26 (Implemented a private PNG caNv (canvas) chunk), PNGsLong gets called unconditionally, but it is only defined if JPEG support is enabled (which defines JNG_SUPPORTED), breaking the build: MagickCore/.libs/libMagickCore-7.Q16HDRI.a(MagickCore_libMagickCore_7_Q16HDRI_la-png.o): In function `WriteOnePNGImage': png.c:(.text+0x748d): undefined reference to `PNGsLong' png.c:(.text+0x74b7): undefined reference to `PNGsLong' Fix it by adding a patch unconditionally defining the helper function. Patch submitted upstream.
