# so that the whole content of trts is included in the enclave.
# 2. For other libraries, you just need to pull the required symbols.
# Use `--start-group' and `--end-group' to link these libraries.
# Do NOT move the libraries linked with `--start-group' and `--end-group' within `--whole-archive' and `--no-whole-archive' options.
