Those who are concerned about maintaining strict conformance with the libjpeg v6b or v7 API can pass an argument of -DWITH_MEM_SRCDST=0 to cmake prior to building libjpeg-turbo. This will restore the pre-1.3 behavior, in which jpeg_mem_src() and jpeg_mem_dest() are only included whe...
Of course, in case the parameters are pointers, they will be modified to let them point to the new virtual address (in other words, a pointer will be subtracted by 16KB to let it point to page 2). Kernel configured as no-MMU To be able to port Zeal 8-bit OS to Z80-based ...
