Maximilian Bosch d9218155d2 ghostscript: use system-wide openjpeg ... The following error occurs when using `imagemagickBig`: $ ./result/bin/identify sample.jp2 [1] 699089 IOT instruction (core dumped) ./result/bin/identify sample.jp2 When looking at the call-trace it seems as if certain symbols, e.g. `opj_malloc` are mixed up: #8 0x00007f78c79ad2f5 in MagickSignalHandler.cold () from /nix/store/bqy80qiw6czqh7vsmmmivwdswp9zzjgl-imagemagick-7.1.0-29/lib/libMagickCore-7.Q16HDRI.so.10 #9 <signal handler called> #10 0x00007f78c5a6095f in opj_malloc () from /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9 #11 0x00007f78c5a60981 in opj_calloc () from /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9 #12 0x00007f78c4f48e24 in opj_create_decompress () from /nix/store/qwalb0kjz1p9c4j48qkk6ql47ds2lnhh-openjpeg-2.4.0/lib/libopenjp2.so.7 The `opj_create_decompress()` is called from the `openjpeg`-integration of `imagemagick` and thus shouldn't affect `ghostscript` at all. However, `ghostscript` (`libgs.so` to be precise) also exposes e.g. `opj_malloc`: $ objdump -t /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9.55|grep opj_malloc 0000000000205940 g F .text 000000000000002b opj_malloc Because of that, two incompatible symbols are used in the same process and thus the `identify`-call breaks because the wrong one is used. To work around that I decided to use the system-wide openjpeg instead. I'm not sure why `libgs.so` wants to expose these symbols anyways, but with that workaround the problem is solved. Even though it's mentioned that ghostscript's openjpeg is heavily patched, I think that this is somewhat outdated or at least irrelevant considering that both ArchLinux[1] and Fedora[2] use the system-wide `openjpeg` instead.
