To whom it may concern,
I wanted to raise a question, regarding binutils-devel shipping libiberty
library with deprecated functions (sys_nerr, sys_errlist) causing the
following errors in Rocky Linux versions using glibbc 2.32 and up.
Why the following doesn't work, if binutils ships liberty specifically for
this? Correct?
Any workaround? If the workaround is to change code and move away from
using liberty, could you please explain the reason why?
Thanks before hand!!
------------------------------
The error we get:
/usr/bin/ld:
/usr/lib/gcc/x86_64-redhat-linux/11/../../../../lib64/libiberty.a(strerror.o):
in function errno_max':
/builddir/build/BUILD/binutils-2.35.2/build-x86_64-redhat-linux/libiberty/../../libiberty/strerror.c:600:
undefined reference to sys_nerr'
Reproduction Steps:
Create file:
$vi errno_max.c
$ cat errno_max.c
#include <stdio.h>
#include <errno.h>
#include <libiberty.h>
int main() {
int max_errno = errno_max();
printf("The maximum value of errno is: %d\n", max_errno);
return 0;
}
Run:
gcc -o errno_max errno_max.c -liberty
Debug version (-v)
gcc -o errno_max errno_max.c /usr/lib64/libiberty.a
