https://bugzilla.suse.com/show_bug.cgi?id=1198449 https://bugzilla.suse.com/show_bug.cgi?id=1198449#c7 --- Comment #7 from Johannes Meixner <jsmeix@suse.com> --- I wished I found more time for things like that but in practice that never happens. For me the main problem is that /usr/share/doc/ghostscript/9.54.0/thirdparty.htm which is also online at https://ghostscript.com/doc/9.54.0/thirdparty.htm does not tell WHY each particular third party library is included in Ghostscript. Using a system library instead of Ghostscript's included library might cause (possibly subtle) regressions because third party sources that are included in the Ghostscript sources are (always/sometimes?) modified by Ghostscript upstream for special Ghostscript needs or Ghostscript depends on the exact version of the included third party source so some (possibly subtle) things may fail when Ghostscript is compiled with the system's library. E.g. see my comments about lcms2 in ghostscript.spec and in ghostscript.changes. I know basically nothing at all about zlib (except it is used for data-compression) so I cannot simply do actually useful things for issues related to zlib in Ghostscript. I would have to digg into the zlib area which requires some "extra" time but that never appears in practice so such issues just hang... -- You are receiving this mail because: You are on the CC list for the bug.
