Re: [Libvir] remove global variables from header files

Hello, I compiled the latest-from-cvs libvirt and was surprised to see link failures. It was because I used -fno-common: .libs/libvirt_la-hash.o:(.bss+0x0): multiple definition of `virDomainFlags' .libs/libvirt_la-libvirt.o:(.bss+0x0): first defined here libvirt_qemud-buf.o:(.bss+0x0): multiple definition of `qemud_packet_type' libvirt_qemud-qemud.o:(.bss+0x0): first defined here libvirt_qemud-buf.o:(.bss+0x4): multiple definition of `qemud_domain_runstate' libvirt_qemud-qemud.o:(.bss+0x4): first defined here Those happen when more than one compilation unit contains a non-extern declaration of the same global variable. In each of the three cases, the name in question appears only at the point of declaration, so one could conceivably simply remove the name, leaving the anonymous "enum". But then there would be no way to declare a variable to be of that type, so I chose to reuse the name, making it the name of the enum. If name space pollution is an issue, and applications that use those headers won't need those types, then it'd be better to remove the names altogether.
