on linux debian 64: x265.h:192:5: error: ‘size_t’ does not name a type

I believe this is caused by cstddef not being included implicitly in new versions of gcc.

See - https://gcc.gnu.org/gcc-4.6/porting_to.html

Henry Vindin: Your patch works. I added the line "#include <cstddef>" to /x265/source/x265.h and rebuilt with success after coming across the same error on a fresh source download.

I do run across a different issue instead when trying to configure FFMPEG with libx265 compiled with this change. From the config.log:

"ERROR: x265 not found using pkg-config /usr/local/include/x265.h:30:19: fatal error: cstddef: No such file or directory #include <cstddef> ^ compilation terminated. ERROR: x265 not found using pkg-config "

api: fix size_t and bool type in x265_picture (fixes #244)

Dan Styles, I believe that the pkg-config errors seen when building ffmpeg are the result of the wiki entries and compilation guides being out of date, there are a huge number of places that issues have been posted regarding the .pc file generated by the x265 build and how ffmpeg should handle it.

You need to make sure that you compile everything correctly although that is not necessarily always the simplest task, but I definitely don't know the intricacies of the compilation of ffmpeg or x265 well enough to provide you with more informed advice.
