Error building qemu on Ubuntu

BottCode commented 4 years ago

Hi,

I'm following these instructions to build Qemu. The ./configure script ends succesfully, while the build process fails. Here's the errors.

make[1]: Entering directory '/home/ubuntu/UNI/qemu/slirp'
make[1]: Nothing to be done for 'all'.
make[1]: Leaving directory '/home/ubuntu/UNI/qemu/slirp'

Makefile:527: recipe for target 'aarch64-softmmu/all' failed
make: *** [aarch64-softmmu/all] Error 2

How can I solve? I've also tryed to remove the -Werror flag from ./dtc/Makefile, but the result is the same.

Hi, try disable Werror by passing -disable-werror to the configure script.

Best regards, Edgar
