Dear Team,

Clang-14.0.6 compilation of source code (c files) fails during linking using ld.lld with below undefined symbols. This issue is observed with glibc-2.35 version.

Please let me know if any input in handling above error?

Hi,

passed libstdc++ path to resolve throw_bad_array_new_length() to LDFLAGS.
But passing libc.so.6 (glibc-2.35) path to LDFLAGS is not resolving below error
{{
ld.lld: error: undefined symbol: __libc_single_threaded
}}

Hi,

gcc-12 linker is not reporting any undefined symbol mentioned in previous comment but clang (ld.lld) only reporting “undefined symbol: __libc_single_threaded” issue with glibc-2.35 installed to toolchain.
