Update.
1998-04-04 Andreas Jaeger <aj@arthur.rhein-neckar.de> * resolv/Makefile: Include ../Makeconfig - needed for building static NSS module. 1998-04-04 Andreas Jaeger <aj@arthur.rhein-neckar.de> * hesiod/Makefile (libnss_hesiod-inhibit-o): Remove condition for static-nss since we don't want hesiod in the static NSS. * nss/Makefile: Build only nss_files as static. * nss/function.def: Remove support for service db. 1998-04-04 09:44 H.J. Lu <hjl@gnu.org> * Makeconfig (CPPFLAGS-.oS): Add -DPIC. 1998-04-04 18:29 Tim Waugh <tim@cyberelk.demon.co.uk> * posix/wordexp-test.c: Make IFS per test-case.

@@ -625,6 +625,33 @@ If you're upgrading from glibc 2.0.x to 2.1 you have to recompile
libstdc++ since the library compiled for 2.0 is not compatible due to the new
Large File Support (LFS) in version 2.1.
+?? Even statically linked programs need some shared libraries
+ which is not acceptable for me. What can I do?
+
+{AJ} NSS (for details just type `info libc "Name Service Switch"')
+won't work properly without shared libraries. NSS allows using
+different services (e.g. NIS, files, db, hesiod) by just changing one
+configuration file (/etc/nsswitch.conf) without relinking any
+programs. The only disadvantage is that now static libraries need to
+access shared libraries. This is handled transparently by the GNU C
+library.
+
+A solution is to configure glibc with --enable-static-nss. In this
+case you can create a static binary that will use only the services
+dns and files (change /etc/nsswitch.conf for this). You need
+to link explicitly against all these services. For example:
+
+ gcc -static test-netdb.c -o test-netdb.c \
+ -lc -lnss_files -lnss_dns -lresolv
+
+The problem with this approach is that you've got to link every static
+program that uses NSS routines with all those libraries.
+
+{UD} In fact, one cannot say anymore that a libc compiled with this
+option is using NSS. There is no switch anymore. Therefore it is
+*highly* recommended *not* to use --enable-static-nss since this makes
+the behaviour of the programs on the system inconsistent.
