Do you need to check if the compiler supports -fno-pic? I know not every version of gcc support -fno-pie, but I'm not sure about -fno-pic. In any case, there is already something in our build system to deal with testing gcc options, which would be useful to you. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
