Bug 62956 – ircii ebuild build attempt: conflicting types for `sys_errlist'

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Jukka Santala 2004-09-05 16:47:39 UTC]

Old sys_errlist conflicting definitions in header-files. sys_errlist definition exists in irc_std.h but was later defined in system header tree (stdio.h->bits/sys_errlist.h) as well.

irc_std.h:
#if !defined(SYS_ERRLIST_DECLARED) && !defined(_Windows)
extern  char    *sys_errlist[];
extern  int     sys_nerr;
#endif

configure.in:
dnl
dnl check for sys_errlist declaration
dnl

AC_MSG_CHECKING(for sys_errlist declaration)
AC_TRY_RUN([
#include <sys/types.h>
#include <stdio.h>
#include <errno.h>
main()
{
  char *s = sys_errlist[0];
  exit(0);
}
],
  AC_MSG_RESULT(yes)
  AC_DEFINE(SYS_ERRLIST_DECLARED),
  AC_MSG_RESULT(no), :)

Not exactly sure how configure ends up thinking sys_errlist isn't defined; since sys_errlist.h makes a distinction between BSD and GNU source, it's possible this is somehow different for the configure test and the actual compile.

Reproducible: Always
Steps to Reproduce:
1. emerge ircii

Actual Results:  
The build finishes configure phase, including:
checking for sys_errlist declaration... no
...after which it breaks with:

well there we are, you now might want to look in config.h and
see if there is anything you might want to tune, else you can
just run a make here.. good luck!

After further testing I traced this into a problem with missing /lib/libtermcap.so.2 symbolic link, that was re-created by ldconfig. This is bug #58567; marking this as invalid.
