Yes, it is expected to fail with -static when link with glibc, may need rebuild glibc with different configuration flags, that why I use static link with musl libc in Alpine environment. Try following if docker is installed DOCKER_BUILDKIT=1 docker build --output out . -f docker/Dockerfile

liudf0716 commented 1 year ago

@skyraintm I understand now. In fact, I believe that Docker is sufficient for use on x86 platforms. We have another team member who is attempting to resolve the problem by including all third-party code within the xfrpc project. This solution may allow for the porting of xfrpc to certain IoT systems, such as RTOS.
