To build the library and related programs, type @code{make}. This will
produce a lot of output, some of which may look like errors from
@code{make} (but isn't). Look for error messages from @code{make}
containing @samp{***}. Those indicate that something is really wrong.
+The compilation process takes several hours even on fast hardware;
+expect at least two hours for the default configuration on i586 for
+Linux. For Hurd times are much longer. All current releases of GCC
+have a problem which causes them to take several minutes to compile
+certain files in the iconvdata directory. Do not panic if the compiler
+appears to hang.

To build and run some test programs which exercise some of the library
facilities, type @code{make check}. This will produce several files
with names like @file{@var{program}.out}.
