cmake -DUSE_TENT=ON ..
make -j
when I use above command, without -DTENT_METRICS_ENABLED=ON, everything is fine

The main reason is the bundled asio in ylt lib is not consistent with OS-installed asio lib. @staryxchen how do you resolve this problem in your developing environment?

@alogfans thanks, by the way, when I use TENT on CUDA, -DUSE_TENT=ON is enough? or I need use -DUSE_TENT=ON -DUSE_CUDA=ON?

Hi @easonyang1010, this is a known build issue when compiling with -DUSE_TENT=ON -DTENT_METRICS_ENABLED=ON. The root cause is:

tent_metrics library is missing the yalantinglibs::yalantinglibs link target (only include dirs were added, missing compile definitions and transitive deps)
tent_metrics_example is missing the asio_shared link dependency (required since the project uses ASIO_SEPARATE_COMPILATION mode)

Temporary Workaround

Apply the following changes manually:

mooncake-transfer-engine/tent/src/metrics/CMakeLists.txt — replace the target_link_libraries line and remove the find_path block at the bottom:

target_link_libraries(tent_metrics PUBLIC tent_common tent_interface yalantinglibs::yalantinglibs glog pthread)

mooncake-transfer-engine/tent/include/tent/metrics/tent_metrics.h — add #include <csignal> before ylt headers:

#if TENT_METRICS_ENABLED
#include <csignal>  // Required before ylt headers: coro_io.hpp uses std::signal/SIGPIPE
#include <ylt/metric.hpp>
#include <ylt/coro_http/coro_http_server.hpp>
#endif

mooncake-transfer-engine/tent/tests/CMakeLists.txt — add asio_shared to the link libraries:

target_link_libraries(tent_metrics_example PRIVATE tent_metrics tent_common asio_shared glog ibverbs)
