@ -174,58 +164,113 @@ Some of the machine-dependent code for some machines uses extensions in
|
||||
the GNU C compiler, so you may need to compile the library with GCC.
|
||||
(In fact, all of the existing complete ports require GCC.)
|
||||
|
||||
The current release of the C library contains some header files that the
|
||||
compiler normally provides: @file{stddef.h}, @file{stdarg.h}, and
|
||||
several files with names of the form @file{va-@var{machine}.h}. The
|
||||
versions of these files that came with older releases of GCC do not work
|
||||
properly with the GNU C library. The @file{stddef.h} file in release
|
||||
2.2 and later of GCC is correct. If you have release 2.2 or later of
|
||||
GCC, use its version of @file{stddef.h} instead of the C library's. To
|
||||
do this, put the line @w{@samp{override stddef.h =}} in
|
||||
@file{configparms}. The other files are corrected in release 2.3 and
|
||||
later of GCC. @file{configure} will automatically detect whether the
|
||||
installed @file{stdarg.h} and @file{va-@var{machine}.h} files are
|
||||
compatible with the C library, and use its own if not.
|
||||
|
||||
There is a potential problem with the @code{size_t} type and versions of
|
||||
GCC prior to release 2.4. ANSI C requires that @code{size_t} always be
|
||||
an unsigned type. For compatibility with existing systems' header
|
||||
files, GCC defines @code{size_t} in @file{stddef.h} to be whatever type
|
||||
the system's @file{sys/types.h} defines it to be. Most Unix systems
|
||||
that define @code{size_t} in @file{sys/types.h}, define it to be a
|
||||
signed type. Some code in the library depends on @code{size_t} being an
|
||||
unsigned type, and will not work correctly if it is signed.
|
||||
|
||||
The GNU C library code which expects @code{size_t} to be unsigned is
|
||||
correct. The definition of @code{size_t} as a signed type is incorrect.
|
||||
Versions 2.4 and later of GCC always define @code{size_t} as an unsigned
|
||||
type, and GCC's @file{fixincludes} script massages the system's
|
||||
@file{sys/types.h} so as not to conflict with this.
|
||||
|
||||
In the meantime, we work around this problem by telling GCC explicitly
|
||||
to use an unsigned type for @code{size_t} when compiling the GNU C
|
||||
library. @file{configure} will automatically detect what type GCC uses
|
||||
for @code{size_t} arrange to override it if necessary.
|
||||
|
||||
To build the library, type @code{make lib}. This will produce a lot of
|
||||
output, some of which looks like errors from @code{make} (but isn't).
|
||||
Look for error messages from @code{make} containing @samp{***}. Those
|
||||
indicate that something is really wrong.

To build the library and related programs, type @code{make}. This will

@code{make} (but isn't). Look for error messages from @code{make}
|
||||
containing @samp{***}. Those indicate that something is really wrong.
|
||||

To build and run some test programs which exercise some of the library
|
||||
facilities, type @code{make tests}. This will produce several files
