Hello, I found this compilation issue on an Ubuntu Yakkety (kernel 4.8.0-30) x86_64 system. When running "make" till the following step: gcc -mno-red-zone -m64 -O1 -g -MMD -MF x86/.vmexit.d -Wall -Werror -fno-omit-frame-pointer -Wno-frame-address -nostdlib -o x86/vmexit.elf -Wl,-T,x86/flat.lds x86/vmexit.o x86/cstart64.o lib/libcflat.a /usr/lib/gcc/x86_64-linux-gnu/6/libgcc.a It will return: /usr/bin/ld: x86/cstart64.o: relocation R_X86_64_32 against `.data' can not be used when making a shared object; recompile with -fPIC This issue won't go away even with x86/cstart64.o recompiled with the -fPIC flag: gcc -fPIC -mno-red-zone -m64 -O1 -g -MMD -MF x86/.cstart64.d -Wall -Werror -fno-omit-frame-pointer -Wno-frame-address -std=gnu99 -ffreestanding -I lib -I lib/x86 -c -nostdlib -o x86/cstart64.o x86/cstart64.S The head of the kvm-unit-test repository is 1bde9127da4c I think maybe it's because the source is assembly code, making the -fPIC flag useless for it? System spec - CPU: Intel i3-4010U - Kernel version: 4.8.0-30-generic #32 - GCC version: gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005 Compilation works fine with Ubuntu Xenial (4.4 kernel, gcc Ubuntu 5.4.0-6ubuntu1~16.04.4 5.4.0 20160609), even with 4.8 kernel on Xenial, so I think this is more related to the compiler or something.
