Guys The update to shadow has caused problems and I needed to rebuild shadow 4.1.4.3-5. I have run into the DSO error regarding libattr. I know I need to update the Makefile.am or patch the Makefile after the ./configure, but I'm not having any luck. The error is: /bin/sh ../libtool --tag=CC --mode=link gcc -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -Wl,-O1,--sort-common,--as-needed,-z,relro,--hash-style=gnu -lcrypt -o useradd useradd.o ../libmisc/libmisc.a ../lib/libshadow.la -lpam -lpam_misc -lacl libtool: link: gcc -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -Wl,-O1 -Wl,--sort-common -Wl,--as-needed -Wl,-z -Wl,relro -Wl,--hash-style=gnu -o .libs/useradd useradd.o ../libmisc/libmisc.a ../lib/.libs/libshadow.so -lcrypt -lpam -lpam_misc -lacl /usr/bin/ld: ../libmisc/libmisc.a(copydir.o): undefined reference to symbol 'attr_copy_fd@@ATTR_1.1' /usr/bin/ld: note: 'attr_copy_fd@@ATTR_1.1' is defined in DSO /lib/libattr.so.1 so try adding it to the linker command line /lib/libattr.so.1: could not read symbols: Invalid operation collect2: ld returned 1 exit status I think I need the explicit -llibattr in the CFLAGS line of the Makefile, but trying to patch it after ./configure isn't working. How do I properly handle this? -- David C. Rankin, J.D.,P.E.
