Build seems to trigger some gcc bug on my machine.

The package does not build in a clean chroot, git is missing from makedepends (not part of base-devel or required by).

@FredBezies: There has been some activity in the comments on the bug report that you filed upstream. From the information posted there about -pie being added to the LDFLAGS from the configure script, they were able to get it to build.

I was also able to replicate this and get 5.1.0.r1440 to compile by interrupting makepkg after it cloned source to srcdir and modifying src/qemu/configure.sh such that it does not add -pie to LDFLAGS. Then run 'makepkg -e' which prevents makepkg from clobbering your changes to configure.sh.

Just manually comment the following lines starting with LDFLAGS and CFLAGS in the following conditional block:

  elif compile_prog "-Werror -fPIE -DPIE" "-pie"; then
  CFLAGS="-fPIE -DPIE $CFLAGS"
  LDFLAGS="-pie $LDFLAGS" 

Alternatively a sed one liner could be added to the prepare() in the PKGBUILD to automate the process.

Edit: This is a hack for now and may have unintended consequences. I needed my VM up and running and didn't have time to check too deeply into the ramifications of removing this compile option.

Opened a bug report about building crashes: https://bugs.launchpad.net/qemu/+bug/1896096

Edit: bug closed as invalid. Looks like this PKGBUILD is going to be busted for a long time. Sorry.

Using nixnack comment, I fixed qemu-git on a buildable version until a fix is provided. Sorry once again.

Still not building :( you would think they would leave the main repo for stable-ish releases.

For those that absolutely need to compile from source, the v5.0.1 (r4? it's the latest one) tagged commit is d0ed6a69d399ae193959225cdeaa9382746c91cc. This could be common knowledge, but I had to RTFM a bit to figure it out.

source=("git://git.qemu.org/qemu.git#commit=d0ed6a69d399ae193959225cdeaa9382746c91cc"
        qemu-ga.service
        65-kvm.rules)

Patched and built without complaining. Obviously this is a one time fix for this single release.

@FredBezies sorry, the patch should be included and is for a raspbian issue.

but i got the same problem as you.

build fails with the same error. At least building works for me:

cd .cache/pikaur/build/qemu-git/src/qemu/build-headless
../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libexecdir=/usr/lib/qemu --extra-ldflags=-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now --smbd=/usr/bin/smbd --enable-modules --enable-sdl --disable-werror --enable-vhost-user --enable-slirp=system --enable-xfsctl --audio-drv-list="pa alsa sdl" --audio-drv-list= \
    --disable-sdl \
    --disable-gtk \
    --disable-vte \
    --disable-brlapi \
    --disable-opengl \
    --disable-virglrenderer

make -j5

cd .cache/pikaur/build/qemu-git/src/qemu/build-full
../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libexecdir=/usr/lib/qemu --extra-ldflags=-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now --smbd=/usr/bin/smbd --enable-modules --enable-sdl --disable-werror --enable-vhost-user --enable-slirp=system --enable-xfsctl --audio-drv-list="pa alsa sdl" 
make -j5

The weird thing is, that it should be exactly the same as the PKGBUILD is doing

Edit: weirder: After doing the above manually recalling pikaur -S qemu-git builds...

@rudolf: will test it right now and we'll see :)

Well, still broken in block/gluster.c

So, your patch is not fixing building process.

@nixknack: it is an upstream issue. They're making a lot of modifications to build process.

Build is failing with many, many linking errors. The 5.1.0.r1 release compiled without issue and I haven't made any changes to my makepkg.conf. Is this an upstream issue?
