Subject: [PATCH] jpeg_memsrcdest: extend feature check
|
||
|
|
|
||
|
|
libjpeg.h in OpenEmbedded master (from libjpeg-turbo 1.5.0) provides
|
||
|
|
these methods if "JPEG_LIB_VERSION >= 80 ||
|
||
|
|
defined(MEM_SRCDST_SUPPORTED)".
|
||
|
|
|
||
|
|
The support for the jpeg_mem functions was added even when not
|
||
|
|
emulating the libjpeg8 API, controlled via the MEM_SRCDST_SUPPORTED
|
||
|
|
define, so checking for the version alone is not enough anymore.
|
||
|
|
|
||
|
|
See https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ab70623eb29e09e67222be5b9e1ea320fe5aa0e9
|
||
|
|
|
||
|
|
This fixes errors about conflicting declarations (signed vs. unsigned
|
||
|
|
char).
