Common Build Issues

1. For cmake type builds, -lxxx fails but both ldconfig and pkg-config can query the library information.

   The link library path is not in the conventional path, the new path is /runtime/lib.

   Add environment variable LIBRARY_PATH=<libpath>, the build environment currently includes this environment variable by default.

2. Static library linking fails during build, requiring rebuild with fPIC.

   Use the -fPIC parameter when building static libraries.

3. Failed to start box during build, as shown below:

   

   The kernel does not support unprivilege namespace, enable unprivilege namespace to resolve.

   sudo sysctl -w kernel.unprivileged_userns_clone=1

4. qtbase builds successfully, but cannot build qt applications, showing module,mkspec related errors.

   Low version fuse-overlay mount has issues, causing file content corruption during qtbase commit, making it unusable. Use fuse-overlayfs >= 1.7 version.
