Conformance of the GNU libc with various standards
|
|
==================================================
|
|
|
|
The GNU libc is designed to be conformant with existing standard as
|
|
far as possible. TO ensure this I've run various tests. The results
|
|
are presented here.
|
|
|
|
|
|
Open Group's hdrchk
|
|
-------------------
|
|
|
|
The hdrchk test suite is available from the Open Group at
|
|
|
|
ftp://ftp.rdg.opengroup.org/pub/unsupported/stdtools/hdrchk/
|
|
|
|
I've last run the suite on 1998-07-08 on a Linux/ix86 system with the
|
|
following results [*]:
|
|
|
|
FIPS No reported problems
|
|
|
|
POSIX90 No reported problems
|
|
|
|
XPG3 No reported problems
|
|
|
|
XPG4 The wide character I/O stuff is missing in glibc.

Beside this a problem in stdio.h is reported but

this is only because the scripts don't understand

the sometimes complex constructs in the header.
|
|
|
|
POSIX96 Same as UNIX98 [see below].
|
|
UNIX98 Quite a lot of problems, almost all due to limitations

of the Linux kernel (2.1.108):

|
|
Only the `wchar.h' problems result from glibc
|
|
defficiencies since we still don't support wide
|
|
character I/O.
|
|
|
|
[*] Since the scripts are not clever enough for the way gcc handles
|
|
include files (namely, putting some of them in gcc-local directory) I
|
|
copied over the iso646.h, float.h, and stddef.h headers and ignored the
|
|
problems resulting from the splitted limits.h file).
