it seems SchemaLoader::get Symbol in libcapnp.a ， and in my bazel build
file like this
cc_library(
name = 'capnp',
visibility = ["//visibility:public"],
hdrs = glob([
"include/capnp/*.h",
"include/capnp/compat/*.h",
"include/kj/*.h",
"include/kj/**/*.h",
]),
srcs = glob([
"lib/libcapnpc.a",
"lib/libcapnp.a",
"lib/libkj.a",
]),
strip_include_prefix = "include",
)
