[Qemu-devel] [Bug 1658120] Re: building with gcc-aarch64-linux-gnu

[Cao Van Dong]

Hello everyone!!

I am having a issue when build qemu using gcc aarch64-linux-gnu-* on
ubuntu 16.04:

address@hidden:~/qemu$ ./configure                                              
    \
>     --prefix=/usr --cross-prefix=/usr/bin/aarch64-linux-gnu-   \
>     --target-list=aarch64-softmmu                              \
>     --enable-attr       --enable-fdt       --enable-kvm        \
>     --enable-sdl        --enable-system    --enable-tools      \
>     --audio-drv-list=                                          \
>     --disable-bluez     --disable-brlapi   --disable-bsd-user  \

Bug description:
  Hi, while trying to build qemu v2.8.0 with gcc-aarch64-linux-gnu
  cross-compiler I'm getting the following :

  
  In file included from /usr/include/x86_64-linux-gnu/sys/syscall.h:31:0,
                   from /root/qemu/util/compatfd.c:21:
  /root/qemu/util/compatfd.c: In function 'qemu_signalfd':
  /root/qemu/util/compatfd.c:103:19: error: '__NR_signalfd' undeclared (first 
use in this function)
       ret = syscall(SYS_signalfd, -1, mask, _NSIG / 8);
                     ^
  /root/qemu/util/compatfd.c:103:19: note: each undeclared identifier is 
reported only once for each function it appears in
  /root/qemu/rules.mak:59: recipe for target 'util/compatfd.o' failed
  make: *** [util/compatfd.o] Error 1

  
  I had configured it with :

  ../configure --target-list=x86_64-linux-user --static --cpu=aarch64

  And I'm on :

  Linux ubuntu-512mb-fra1-01 4.4.0-59-generic #80-Ubuntu SMP Fri Jan 6
  17:47:47 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

  Thanks
