I got new results, I found this problem comes from using capnp by python
and c++ in the same project while Interface has been declared within .capnp
which are used in c++ project.
for example:
// main.cpp
#include <pybind11/embed.h>
namespace py = pybind11;
int main() {
py::scoped_interpreter guard{};
py::exec(R"(
message = "Start example"
print(message)
import capnp
import address_capnp
message = "Import address_capnp done successfully"
print(message)
)");
}
# address.capnp
@0x85150b117366d14b;
struct Person {
id @0 :UInt32;
name @1 :Text;
email @2 :Text;
}
interface AddressMethod {
func @0 (count: Int8 ) -> ();
}
# CMakeLists
cmake_minimum_required(VERSION 3.0)
project(example)
find_package(pybind11 REQUIRED)
find_package(CapnProto REQUIRED)
capnp_generate_cpp(addressSources addressHeaders address.capnp)
add_executable(example ${addressSources} main.cpp)
target_link_libraries(example PRIVATE CapnProto::capnp-rpc pybind11::embed)
The above example will work as long as interface AddressMethod in
address.capnp is removed.
Can anyone help me?
