[-- Attachment #1 --] On arm, ia64, powerpc and sparc, Linux doesn't define a static PAGE_SIZE. It can only be obtained via sysconf(). In addition, GNU/Hurd doesn't define PAGE_SIZE at all. This patch improves portability of libsbuf to be built on those platforms. In case you'd like to know, Debian is using libsbuf not just for its GNU/kFreeBSD port, but also provides it to developers in Debian GNU/Linux: http://packages.debian.org/search?keywords=libsbuf-dev https://buildd.debian.org/status/package.php?p=freebsd-libs&suite=sid -- Robert Millan [-- Attachment #2 --] Index: sys/kern/subr_sbuf.c =================================================================== --- sys/kern/subr_sbuf.c (revision 223721) +++ sys/kern/subr_sbuf.c (working copy) @@ -76,6 +76,11 @@ #define SBUF_SETFLAG(s, f) do { (s)->s_flags |= (f); } while (0) #define SBUF_CLEARFLAG(s, f) do { (s)->s_flags &= ~(f); } while (0) +#if !defined(PAGE_SIZE) && !defined(_KERNEL) +#include <unistd.h> +#define PAGE_SIZE sysconf(_SC_PAGESIZE) +#endif + #define SBUF_MINEXTENDSIZE 16 /* Should be power of 2. */ #ifdef PAGE_SIZE
