Hi guys, I made a automated test for the libvirt code in git source repository right now, It reported a check error. The operation steps and error info are as following: ubuntu@ubuntu:~/github/libvirt.git$ ./autogen.sh ubuntu@ubuntu:~/github/libvirt.git$ ./configure --enable-werror ubuntu@ubuntu:~/github/libvirt.git$ make check ............ make check-local make[3]: Entering directory `/home/ubuntu/github/libvirt.git/daemon' GEN check-augeas make[3]: Leaving directory `/home/ubuntu/github/libvirt.git/daemon' make[2]: Leaving directory `/home/ubuntu/github/libvirt.git/daemon' make[1]: Leaving directory `/home/ubuntu/github/libvirt.git/daemon' Making check in tools make[1]: Entering directory `/home/ubuntu/github/libvirt.git/tools' GEN libvirt-guests.sh make check-am make[2]: Entering directory `/home/ubuntu/github/libvirt.git/tools' CC virsh-virsh.o CC virsh-virsh-console.o CC virsh-virsh-domain.o virsh-domain.c: In function 'cmdMetadata': virsh-domain.c:6857:10: error: declaration of 'remove' shadows a global declaration [-Werror=shadow] cc1: all warnings being treated as errors make[2]: *** [virsh-virsh-domain.o] Error 1 make[2]: Leaving directory `/home/ubuntu/github/libvirt.git/tools' make[1]: *** [check] Error 2 make[1]: Leaving directory `/home/ubuntu/github/libvirt.git/tools' make: *** [check-recursive] Error 1 What's the problem?
