Hi,
I m trying to build libcap on debian/hurd and the error said no <sys/prctl.h> found. I searched around and found that each operating system has different implementation and names for system calls. So I tried to read what prctl.h provided and found out that it provided operations on threads or process. I looked at the hurd manual to look for the threads library which pointed to libthreads. Am I missing something? Should I look into libhtreads and find a function that is has a similar function and similar to prctl and replace it in the libcap file?
