I'm sorry to be so blunt but this is completely wrong/ backwards: Prior to libc6, /usr/include/linux used to be a symlink to the actual source tree the kernel was compiled from. This practice was dropped because applications using a certain, compiled version of glibc need to be compiled with the same kernel headers as the C library was to ensure that both agree wrt structure definitions. Since then, glibc included a certain set of kernel headers. Linux has the nice policy of never changing a public ABI, hence, there's no problem in this respect (I'm right now running with a 4.5.0 kernel on a Wheezy system because some code changes of mine went into Linux when that was current). _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
