Looking for information about libjpeg-turbo API update wrt. libjpeg 9 I found this: http://sourceforge.net/mailarchive/forum.php?thread_name=50E29F02.9060804%40users.sourceforge.net&forum_name=libjpeg-turbo-devel
It looks that libjpeg-turbo fully implements libjpeg features up to 6b, with partial API/ABI emulation (not full implementation) up to 8b (not even 8c as stated by Provides in libjpeg-turbo), unlikely to really support API 9 or fully support libjpeg 7+ additions. What to do now? One solution could be to ship libjpeg-turbo as libjpeg.so.6 (or even libjpeg.so.8, doesn't matter much) with development libjpeg.so symlink (so by default we get SIMD-accelerated basic JPEG support) and ship libjpeg 9 (as libjpeg.so.9) with different development symlink (libjpeg9.so or maybe libjpeg-ijg.so). Disadvantages: - it needs identification of packages relying on libjpeg 7+ functionality and patching them to link with -ljpeg9 - symbol clashes when libraries using libjpeg-turbo and libjpeg9 meet in common code space Second solution: use IJG libjpeg 9 by default and libjpeg-turbo only where needed (mostly mozilla products). Disadvantage: no SIMD accelaration outside few applications Other ideas? -- Jakub Bogusz http://qboosh.pl/ _______________________________________________ pld-devel-en mailing list [email protected] http://lists.pld-linux.org/mailman/listinfo/pld-devel-en
