On x86_64 if GPR_MUSL_LIBC_COMPAT is not set, grpc tries to link with
memcpy@GLIBC_2.2.5, see:
618a3f561d/src/core/lib/gpr/wrap_memcpy.cc
Add a new GPR_DISABLE_WRAPPED_MEMCPY to disable wrapped memory without
changing CPU behavior

Subject: [PATCH] wrap_memcpy.cc: add GPR_DISABLE_WRAPPED_MEMCPY
|
|
|
|
Add GPR_DISABLE_WRAPPED_MEMCPY to allow the user to disable wrapped
|
|
memcpy. This will fix build on x86_64 on musl/uclibc without changing
|
|
the cpu behavior.
