Public bug reported:
The version of /usr/include/time.h included with libc6-dev-2.12.1-0ubuntu10
contains an inconsistency between :
line 212: # ifdef __USE_XOPEN2K8 (which introduces a block where __locale_t
is defined)
line 223: # ifdef __USE_GNU (which introduces a block where
__locale_t is used)
therefore, a compilation error occurs when __USE_GNU is defined and not
__USE_XOPEN2K8, which unfortunately I have when compiling user's
functions for my application code (ansys). To demonstrate the problem ,
the simple code :
#include "stdio.h"
#define __USE_GNU
#include "time.h"
int main() {return 0;}
will not compile with gcc -ansi
It seems that this problem is due to the modification of the glibc
source code by Ulrich Drepper on 2009-02-26 (as found on the site
http://sourceware.org/git/?p=glibc.git&a=search&h=HEAD&st=commit&s=time.h
which is the "ressource" to track evolutions from the official gnu C
library site www.gnu.org/software/libc/resources.html)
I post this bug here, as indicated by glibc maintainers, for those (as
me) who use glibc through a linux distribution (ubuntu10.10 on x86_64,
for me)
