[Mac M1] Failed to use Folly on Mac M1

[Zheng-Bicheng]

I use "CMake" to build my project, but I encounter numerous errors when linking with Folly, like:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk/usr/include/c++/v1/cstddef:50:9: error: no member named 'nullptr_t' in the global namespace

My CMakeLists is

cmake_minimum_required(VERSION 3.0)
project(untitled3)

set(CMAKE_CXX_STANDARD 14)

add_executable(untitled3 main.cpp)

find_package(Folly REQUIRED)
target_include_directories(untitled3 PRIVATE ${FOLLY_INCLUDE_DIR})
message(${FOLLY_LIBRARIES})
target_link_libraries(untitled3 PRIVATE Folly::folly)

I want to know how I can resolve these challenging issues.

I had the same problem.

Reproduced this issue on my M1 Mac as well.

I used the following workarounds.

1: Use mac ports instead of brew I experienced the conflict between headers in brew and CLT before: stackoverflow link . Using mac ports to install folly seems to help me temporarily fix this problem.

sudo port install folly
brew uninstall folly

Sample CMakeLists.txt as below:

cmake_minimum_required(VERSION 3.0)
project(untitled3)

set(CMAKE_CXX_STANDARD 14)

add_executable(untitled3 main.cpp)

find_package(Folly REQUIRED)
find_package(gflags REQUIRED)
target_include_directories(untitled3 PRIVATE ${FOLLY_INCLUDE_DIR})
message(${FOLLY_LIBRARIES})
target_link_libraries(untitled3 Folly::folly)

2: Build from the source code Use git submodule add https://github.com/facebook/folly.git to add folly into your project and install necessary dependencies.

cmake_minimum_required(VERSION 3.10)
project(MyFollyProject)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

add_subdirectory(folly)
add_executable(main main.cpp)
target_link_libraries(main folly)
