I believe there are indeed qemu bugs here. It's actually the qemu configure script which is adding `-pie' $ echo $LDFLAGS -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now Yet meson-logs/meson-log.txt tells me that: Using 'LDFLAGS' from environment with value: '-g -pie -Wl,-O1,--sort- common,--as-needed,-z,relro,-z,now' Where did the `-pie' come from? Answer: the qemu configure script! https://git.qemu.org/?p=3Dqemu.git;a=3Dblob;f=3Dconfigure;h=3D756447900855e= 0b886ec6eb4e6b6aecf48c20a97;hb=3DHEAD#l2250 Simply unsetting LDFLAGS allows the build to complete successfully. Not only that, qemu is now ignoring my user supplied CFLAGS from the environment. I haven't analysed this one yet but I'm starting to realise this hybrid meson/configure script approach is quite complicated. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1896096 Title: Git version: Build process is broken in block_curl.c.o Status in QEMU: Invalid Bug description: Gcc version: 10.2.0 Glusterfs: 8.1 Libguestfs: 1.42 Configure options used: configure \ --prefix=3D/usr \ --sysconfdir=3D/etc \ --localstatedir=3D/var \ --libexecdir=3D/usr/lib/qemu \ --extra-ldflags=3D"$LDFLAGS" \ --smbd=3D/usr/bin/smbd \ --enable-modules \ --enable-sdl \ --disable-werror \ --enable-slirp=3Dsystem \ --enable-xfsctl \ --audio-drv-list=3D"pa alsa sdl" = Error log attached.
