I won't pretend to know exactly which header files correspond for your port, but in the past I've found some things that work for me: use locate vfs.h to find similar file names. On 6.x and 5.x I see that these are possible candidates: /usr/X11R6/include/gnome-vfs-2.0/libgnomevfs/gnome-vfs.h /usr/include/fs/devfs/devfs.h /usr/include/sys/statvfs.h /usr/local/include/af_vfs.h /usr/src/sys/compat/svr4/svr4_statvfs.h /usr/src/sys/fs/devfs/devfs.h /usr/src/sys/nfs4client/nfs4_vfs.h /usr/src/sys/sys/statvfs.h But you'd have to compare the functions and structures defined in sys/vfs.h on linux to determine which is your best match up. There is /usr/ports/devel/mipsel-linux-kernel-headers/ which, according to pkg-plist will install mipsel-linux/include/linux/vfs.h. That may be exactly what you need (although it may be overkill). Or it may be the LAST thing you need :) Sometimes a porter will simply create a patch file in /usr/ports/<portname>/files that will create a skeleton version of the file which includes only the items you need. I've done this for development on my own system. As far as the NGROUP or other macros ... yikes! You may have to recreate that functionality entirely. I ran this: #!/bin/sh for each in `locate .h | grep '\.h$'` do if [ -f $each ]; then MYF=`cat $each | grep -i ngroups` if [ "x$MYF" != "x" ]; then echo $each : "$MYF" fi MYF="" fi done It could probably be done more easily with sed and some elbow grease, but it does show NGROUPS defined here: /usr/X11R6/include/X11/Xos.h : #define NGROUPS 16 and /usr/include/sys/param.h among other places.
