This issue is different from the one described at #1252 .

In a Windows project of mine, building cpprestsdk against asio, without websockets, I get following unresolved external errors:

http_client_asio.obj : error LNK2019: unresolved external symbol "public: static class crossplat::threadpool & __cdecl crossplat::threadpool::shared_instance(void)" (?shared_instance@threadpool@crossplat@@SAAEAV12@XZ) referenced in function "public: __cdecl web::http::client::details::asio_connection_pool::asio_connection_pool(void)" (??0asio_connection_pool@details@client@http@web@@QEAA@XZ) [src\cpprest.vcxproj]
http_server_asio.obj : error LNK2001: unresolved external symbol "public: static class crossplat::threadpool & __cdecl crossplat::threadpool::shared_instance(void)" (?shared_instance@threadpool@crossplat@@SAAEAV12@XZ) [src\cpprest.vcxproj]

My environment

  • cpprestsdk 2.10.16 @ 7fbb08c
  • VS2019

Repro steps
From the command prompt at the root folder containing cpprestsdk and its internal vcpkg

cpprestsdk\vcpkg\bootstrap-vcpkg.bat
cpprestsdk\vcpkg\vcpkg.exe install boost-asio:x64-windows
mkdir build.asio
cd build.asio
cmake -A x64 -DCMAKE_TOOLCHAIN_FILE="..\cpprestsdk\vcpkg\scripts\buildsystems\vcpkg.cmake" -DCPPREST_HTTP_CLIENT_IMPL=asio -DCPPREST_HTTP_LISTENER_IMPL=asio -DCPPREST_EXCLUDE_WEBSOCKETS:BOOL=ON -DCPPREST_EXCLUDE_COMPRESSION:BOOL=ON -DBUILD_TESTS:BOOL=OFF -DBUILD_SAMPLES:BOOL=OFF "..\cpprestsdk\Release"
cmake --build .
