[libvirt-users] build error on CentOS 5

I'm getting the following error when building libvirt 10.2 from source in CentOS 5: CC libvirt_util_la-processinfo.lo util/processinfo.c: In function 'virProcessInfoGetAffinity': util/processinfo.c:164: error: invalid operands to binary | The line in question is: 162 for (i = 0 ; i < maxcpu ; i++) 163 if (CPU_ISSET(i, &mask)) 164 VIR_USE_CPU(map, i); Where VIR_USE_CPU is defined as the following in libvirt.h: #define VIR_USE_CPU(cpumap,cpu) (cpumap[(cpu)/8] |= (1<<((cpu)%8))) I have glibc 2.5 installed, which is why CPU_ALLOC is undefined (added in 2.7). I'm also using a custom 2.6.32 kernel. I can provide configure output and any additional system details if necessary. Has anyone else seen this? Ben Clay rbclay(a)ncsu.edu
