解决方法
- 在Makefile中找到
-Werror项，删除即可。删除后重新编译。 -
或设置环境变量 c工程设置
export CFLAGS = "-Wno-error"
c++工程设置
export CXXFLAGS = "-Wno-error" -
或自动化配置工具添加选项
./config -no-warnings-are-errors

Install a hypervisor When setting up Kata using a packaged installation method, the QEMU VMM is installed automatically. Cloud-Hypervisor and Firecracker VMMs are available from the release tarballs. You may choose to manually build your VMM/hypervisor. Build a custom QEMU Kata Containers makes use of upstream QEMU branch. The exact version and repository utilized can be found by looking at the runtime's versions file Kata often utilizes patches for not-yet-upstream fixes for components, including QEMU. These can be found in the packaging repository in the QEMU directory. To build utilizing the same options as Kata, you should make use of the configure-hypervisor.sh script. For example: $ go get -d github.com/kata-containers/packaging $ cd $your_qemu_directory $ ${GOPATH}/src/github.com/kata-containers/packaging/scripts/configure-hypervisor.sh qemu > kata.cfg $ eval ./configure "$(cat kata.cfg)" $ make -j $(nproc) $ sudo -E make install See the static-build script for QEMU for a reference on how to get, setup, configure and build QEMU for Kata. Build a custom QEMU for aarch64/arm64 - REQUIRED Note: You should only do this step if you are on aarch64/arm64. You should include Eric Auger's latest PCDIMM/NVDIMM patches which are under upstream review for supporting NVDIMM on aarch64. You could build the custom qemu-system-aarch64 as required with the following command: $ go get -d github.com/kata-containers/tests $ script -fec 'sudo -E ${GOPATH}/src/github.com/kata-containers/tests/.ci/install_qemu.sh'
