Because that would have been 8000 more lines to convert and more bugs that would not have been caught before the merge. The problem with having custom Makefiles is that some rebases were horrible. When going from 4.2 to 5.1, there were a couple merge commits that took me one day each! In addition, compared to Libvirt adding new source files seemed much more common in QEMU. Basically the conversion was merged in the "worst possible state that can already be considered an improvement", in order to focus on fixing bugs and progressing in the conversion, rather than on rebases. I must admit it was a bit worse than expected, but as long as maintainers have not been blocked in their work it's still more or less going according to plan. -- 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=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --libexecdir=/usr/lib/qemu \ --extra-ldflags="$LDFLAGS" \ --smbd=/usr/bin/smbd \ --enable-modules \ --enable-sdl \ --disable-werror \ --enable-slirp=system \ --enable-xfsctl \ --audio-drv-list="pa alsa sdl" Error log attached.

You can include the output of the build to help debugging this further failure. LDFLAGS has legitimate used but I think it would make sense to fail configure if LDFLAGS contains -pie.

[Bug 1896096] Re: Git version: Build process is broken in block_curl.c.o
Huh. I thought we ignored the environment LDFLAGS/CFLAGS from much earlier than 5.0 and was about to ask if honouring it was a change introduced with the Meson switch! My (not necessarily very considered) opinion is that generally it's better not to honour the environment CFLAGS and LDFLAGS because they can have all sorts of random stuff in them that just doesn't work in complicated cases like QEMU, as in this example where they included "-pie". --extra-ldflags has the semantics of "add these on top of whatever the standard set of QEMU build flags is" so the user doesn't need to try to specify absolutely everything, and it's clear from the configure line that extra non-default options are being added. -- 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=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --libexecdir=/usr/lib/qemu \ --extra-ldflags="$LDFLAGS" \ --smbd=/usr/bin/smbd \ --enable-modules \ --enable-sdl \ --disable-werror \ --enable-slirp=system \ --enable-xfsctl \ --audio-drv-list="pa alsa sdl" Error log attached.

[Bug 1896096] Re: Git version: Build process is broken in block_curl.c.o
Chiming in here as the user who initially suggested Arch use this: --extra-ldflags="$LDFLAGS" qemu-5.0.0 introduced a breaking change whereby LDFLAGS from the environment were ignored. For Arch, this resulted in exclusion of `--as- needed' from the link, which naturally caused dependency chaos. The Arch Build System globally sets CFLAGS and LDFLAGS in the build environment to try and ensure all pkgs are built to distro standards. The build systems for most pkgs in the distro respect FLAGS from the environment. When qemu-5.2.0 is released, Arch will obviously need to adapt to account for Meson changes. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1896096 Title: Git version: Build process is broken in block_curl.c.o Status in QEMU: Invalid Bug description: Gcc version: 10.2.0 Glusterfs: 8.1 Libguestfs: 1.42 Configure options used: configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --libexecdir=/usr/lib/qemu \ --extra-ldflags="$LDFLAGS" \ --smbd=/usr/bin/smbd \ --enable-modules \ --enable-sdl \ --disable-werror \ --enable-slirp=system \ --enable-xfsctl \ --audio-drv-list="pa alsa sdl" Error log attached.

You have to unset LDFLAGS, or remove -pie. Specifying --extra-ldflags is useless because Meson already obeys the LDFLAGS environment variable.

Before the meson port, the "-pie" arg was on the CLI *before* the "-shared" arg so the "-shared" wins and results in a shared library.

[Bug 1896096] Re: Git version: Build process is broken in block_curl.c.o
The problem is caused by the extra flags you're forcing on the compiler: Using 'CFLAGS' from environment with value: '-O2 -g -fPIE -DPIE -std=gnu99 -Wall' Using 'LDFLAGS' from environment with value: '-g -pie -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now' Using 'CPPFLAGS' from environment with value: '-D_FORTIFY_SOURCE=2' Most particularly the "-pie" in LDFLAGS. This is only valid for executables, not shared libraries, and thus it breaks the build. -- 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: New Bug description: Gcc version: 10.2.0 Glusterfs: 8.1 Libguestfs: 1.42 Configure options used: configure \ --prefix=/usr \ --sysconfdir=/etc \ --localstatedir=/var \ --libexecdir=/usr/lib/qemu \ --extra-ldflags="$LDFLAGS" \ --smbd=/usr/bin/smbd \ --enable-modules \ --enable-sdl \ --disable-werror \ --enable-slirp=system \ --enable-xfsctl \ --audio-drv-list="pa alsa sdl" Error log attached.
