FreeBSD has a sysinfo utility, see "man 8 sysinfo", which can be obtained with the "sysinfo" package. But as far as I can see, it's implemented via shell scripts. On Linux systems, sysinfo.h is a system-level header file. >From this file (example of a sysinfo.h file): http://www.scs.stanford.edu/histar/src/pkg/uclibc/include/sys/sysinfo.h More precisely: sysinfo.h is part of the GNU C library (glibc) include files, where sysinfo() is a library function, not an external program. See for example: http://www.informit.com/articles/article.aspx?p=23618&seqNum=15 Also see: http://man7.org/linux/man-pages/man2/sysinfo.2.html Let me quote: "This function is Linux-specific, and should not be used in programs intended to be portable." Summary: It's a Linuxism. :-) But maybe you can "fake" the required functionality somehow through FreeBSD's Linux ABI... There are also ports which seem to install a sysinfo.h file (search for *.plist containing "sysinfo.h"), for example devel/libgtop or lang/gnatdroid-sysroot. Maybe that's a way to get the required files? -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
