Head commit for run: 4db26c70b9d84c0236bbbdcc31825bb41ee14fd8 / Ruihang Lai <[email protected]> [CI] Static-link libstdc++ for Linux wheel builds The Linux manylinux_2_28 wheels fail their cibuildwheel test step with "undefined symbol: ...basic_string..._M_replace_cold@GLIBCXX_3.4.30" when importing tvm. The C++20 baseline requires a newer gcc-toolset (GCC 14 in the current manylinux image), whose libstdc++ emits symbols newer than the manylinux runtime baseline. Because auditwheel does not bundle libstdc++, the wheel ends up with a runtime dependency on a libstdc++ that the test/host environment does not provide. Add LDFLAGS="-static-libstdc++ -static-libgcc" to the Linux wheel build environment so the C++ runtime is linked statically into libtvm.so / libtvm_runtime.so, removing the dynamic libstdc++ dependency. macOS (libc++) and Windows (MSVC STL) are unaffected.
