[Q14] ``When linking with the new libc I get unresolved symbols
`crypt' and `setkey'. Why aren't these functions in the
libc anymore?''
[A14] {UD} Remember the US restrictions of exporting cryptographic
programs and source code. Until this law gets abolished we cannot
ship the cryptographic function together with the libc.
But of course we provide the code and there is an very easy way to use
this code. First get the extra package. People in the US way get it
from the same place they got the GNU libc from. People outside the US
should get the code from ftp.uni-c.dk [129.142.6.74], or another
archive site outside the USA. The README explains how to install the
sources.
If you already have the crypt code on your system the reason for the
failure is probably that you failed to link with -lcrypt. The crypto
functions are in a separate library to make it possible to export GNU
libc binaries from the US.
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
[Q15] ``What are these `add-ons'?''
[A15] {UD} To avoid complications with external or external source
code some optional parts of the libc are distributed as separate
packages (e.g., the crypt package, see Q14).
To ease the use as part of GNU libc the installer just has to unpack
the package and tell the configuration script about these additional
subdirectories using the --enable-add-ons option. When you add the
crypt add-on you just have to use
configure --enable-add-ons=crypt,XXX ...
where XXX are possible other add-ons and ... means the rest of the
normal option list.
You can use add-ons also to overwrite some files in glibc. The add-on
system dependent subdirs are search first. It is also possible to add
banner files (use a file named `Banner') or create shared libraries.
Using add-ons has the big advantage that the makefiles of the GNU libc
can be used. Only some few stub rules must be written to get
everything running. Even handling of architecture dependent
compilation is provided. The GNU libc's sysdeps/ directory shows how
to use this feature.
