Start by reading install.sh and reproducing the USE_BALANCE_SERVE=1 build at csrc/balance_serve/build with the stated CMake command. Capture the full verbose error and compare it with the Ubuntu, CUDA, and driver versions reported in the issue. Done means the balance_serve build completes successfully or the incompatibility is documented and isolated.
