Installation: 1) to build and install the commandline tools (nfs4_getfacl, nfs4_setfacl): $ autoreconf $ make $ make install 2) in case of trouble, please see "Random Notes" below or contact linux-nfs@vger.kernel.org. Random Notes (about some distros..): the install targets "install-lib" and "install-dev", aren't actually wired-up. we're not yet sure whether to prune this entirely or come back and do it for real. looks for /usr/include/attr/attr.h, but 'attr' dir doesn't exist for me. after looking at the paths on my (old SuSE) system, i found that this worked: sudo ln -s /usr/include/linux /usr/include/attr a different environment is building the 'attr' package wrong. 1) doesn't install xattr.h, 2) isn't installing libattr.la, libattr.a, or libattr.so.1.1.0. W/r/t the latter, i saw errors like: libtool: link: cannot find the library `/usr/lib/libattr.la' or unhandled argument `/usr/lib/libattr.la' gmake[1]: *** [nfs4_getfacl] Error 1 make: *** [default] Error 2 if you have a libattr shared library and still see the above error, rerunning `configure' and `make' should probably fix the problem. please send any email to .
