While trying to install qemu-5.2.0, I found the build method has changed to mesa.(I don't know why they change things sometimes to make our lives difficult... :) )
Under build directory, I did ../configure --target-list=aarch64-softmmu --enable-debug as usual, and it gave me at the last line
ERROR: Could not detect Ninja v1.7 or newer
I tried installing ninja by sudo apt-get install ninja and in removed old version and re-installed ninja. But as you can see, the installed ninja version is too low. (it expects 1.7 or newer)
ckim@chan-ubuntu:~$ dpkg -l | grep ninja
ii ninja 0.1.3-2 amd64 Privilege escalation detection system for GNU/Linux
rc ninja-build 1.5.1-0.1ubuntu1 amd64 small build system closest in spirit to Make
What is the best way to install Ninja 1.7 or newer? (I'm on ubuntu 16.04)
ADD :
I found you can install ninja 1.7 on ubuntu 16.05 : git clone github.com/ninja-build/ninja.git, then cd ninja; git checkout v1.7.0; ./configure --bootstrap. now ninja is built on that local directory. you link to previous ninja executable like /usr/bin/ninja. this works ok. (but as others said, upgrading to higher version of ubuntu might be better)
