Hi List Is it possible to build xentools without ipxe? I ask as that looks by design impossible to build with using clang and I don't want to have to bring in another toolchain just for this. error: fields must have a constant size: 'variable length array in structure' extension will never be supported" See the root cause here: https://github.com/ipxe/ipxe/blob/827dd1bfee67daa683935ce65316f7e0f057fe1c/src/include/ipxe/pccrc.h#L146 I note that older xentools don't force gcc but do include the above - how is that done and can it be done for xentools48?
