Thanks for reporting this. Peter Maydell looked into this and answered it in another email thread: "this looks like a QEMU incompatibility with newer glibc that we fixed in QEMU commit 75e5b70e6b5dcc4. That didn't quite make the 2.11.0 release, but will be in 2.12.0." > CC util/qemu-thread-posix.o > CC util/memfd.o > util/memfd.c:40:12: error: la déclaration statique de « memfd_create » suit > une déclaration non statique > static int memfd_create(const char *name, unsigned int flags) > ^~~~~~~~~~~~ > In file included from /usr/include/bits/mman-linux.h:115:0, > from /usr/include/bits/mman.h:45, > from /usr/include/sys/mman.h:41, > from > /usr/local/src/qemu-2.11.1/include/sysemu/os-posix.h:29, > from /usr/local/src/qemu-2.11.1/include/qemu/osdep.h:104, > from util/memfd.c:28: > /usr/include/bits/mman-shared.h:46:5: note: la déclaration précédente de > « memfd_create » était ici > int memfd_create (const char *__name, unsigned int __flags) __THROW; > ^~~~~~~~~~~~ > make: *** [/usr/local/src/qemu-2.11.1/rules.mak:66: util/memfd.o] Error 1
