Re: [libvirt] gnulib tests in libvirt broken by newer glibc 2.26

This tip is not helpful: I spent two hours trying Fedora Rawhide, and the version of today is not functional: the live ISO shows a desktop in which all you can do is to reboot, and the installation ISO does an installation but the installed system does not boot. So we are back to the support mode where we ask for pieces of information for analysis by us (gnulib developers). > ./configure gl_cv_func_getopt_posix=no ac_cv_header_getopt_h=no This mode of configuration is not the usual one. (Why, if you are on a glibc system, would you want to avoid the system's <getopt.h> header and getopt() function?) But anyway, it should be supported, and the result should be a 'test-getopt-posix' program that uses gnulib's replacement: $ nm test-getopt-posix | grep getopt 000000000060a160 b getopt_data 0000000000405b90 T _getopt_internal_r 0000000000400f90 t getopt_loop.constprop.0 0000000000406170 T rpl_getopt 0000000000406110 T rpl_getopt_internal 0000000000401130 t test_getopt

Can you show three things, please?

From my own F28 rawhide install with glibc-2.26.90-16.fc28.x86_64

1) The output of $ nm test-getopt-posix | grep getopt

2) The output of $ gcc -DHAVE_CONFIG_H -DGNULIB_STRICT_CHECKING=1 -I. -I.. -I../gllib -g -O2 -E test-getopt-posix.c

3) The output of $ gcc -DHAVE_CONFIG_H -DGNULIB_STRICT_CHECKING=1 -I. -I.. -I../gllib -g -O2 -E -dM test-getopt-posix.c
