I found that using FreeBSD Port fam for the daemon with openSUSE 10 fam 2.7.0 for my /compat/linux/lib/libfam.so* worked. Other fam versions from other linux distributions failed. I'm able to detect file changes with a linux binary that employs libfam.so. I tested it using the fileschanged application provided with the linux fam version. qbmonitord also works with this configuration. I have the following: * compat_linux enabled in the kernel, * /usr/ports/emulators/linux_base_fc7 * sysctl kern.fallback_elf_brand=3 * rpm2cpio to alter rpms * cpio to create the directories and place the files where they belong in /compat/linux. I have a program that now has all it's libraries resolved but one in preparation to attempt to run the Linux Quickbooks install on FreeBSD. The ldd output, prior to installing /usr/ports/devel/fam (a required shared library) looks like this. ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: libfam.so.0 = not found libpthread.so.0 = /lib/libpthread.so.0 (0x28072000) libstdc++.so.6 = /usr/lib/libstdc++.so.6 (0x28088000) libm.so.6 = /lib/libm.so.6 (0x28171000) libgcc_s.so.1 = /lib/libgcc_s.so.1 (0x28198000) libc.so.6 = /lib/libc.so.6 (0x281a4000) /lib/ld-linux.so.2 (0x28054000) I install fam to get rid of the not found, perform the following link: ln /usr/local/lib/libfam.so.0 /compat/linux/lib/libfam.so.0 and then I get this: ldd ./opt/qbes7/util/qbmonitord ./opt/qbes7/util/qbmonitord: ./opt/qbes7/util/qbmonitord: error while loading shared libraries: / lib/libfam.so.0: ELF file OS ABI invalid ./opt/qbes7/util/qbmonitord: exit status 127 which kind of makes sense since this library is not a linux library.

Oops, I didn't ever notice that list as I've never needed Linux before. I hate to trouble development lists with an operational issue but this one is starting to look like an incompatibility that is beyond me. The Linux and FreeBSD versions of gamin both fail on inotify_init. Not having the source to the program I'm trying to run makes it very difficult to fix even though the functionality is there (perhaps even superior) on FreeBSD. I ended up using the linux libfam.so.0 from the gamin distribution for Fedora 9. Using it's server fails instantly, using the freebsd port version, the server doesn't fail until the Linux client library attempts to connect. Then it too gets inotify_init not implemented. The Fam list appears to be defunct and I've not yet tried the direct mail contact to the gamin development page. I'm assuming the answer would be that you use native FreeBSD libfam.so on FreeBSD and the linux version on Linux. I've no way to tell the Intuit daemon to do that because of the ABI error and I presume there is an underlying reason why a native library can't be used by a linux binary. I will try the other list if no one has run into a similar problem with other Linux apps. I may be kicking a dead horse but it seems others have talked about using FreeBSD in this manner and it makes it an interesting challenge. The time I'm investing in this is probably not any more time that it would take to configure and secure an openSUSE or Fedora system (having never bothered with them before). Plus it would mean not adding an additional server into my net just for a trivial SMB/file monitoring application. Thanks for the response.
