quantum won't compile due to usage of non-standard and non-portable C++ extensions

[robinchrist]

I was trying to include quantum simply as a subproject, but I can even get it to work in a very reduced example.

First approach (what should work for a properly written header only library based on CMake):

add_executable(TestExec main.cpp)
add_subdirectory(quantum)
target_link_libraries(TestExec PUBLIC quantum)

Does not work, because:

[1/2] Building CXX object CMakeFiles/TestExec.dir/main.cpp.o
FAILED: CMakeFiles/TestExec.dir/main.cpp.o 
/usr/bin/c++ -DBOOST_ALL_NO_LIB -DBOOST_CONTEXT_DYN_LINK  -fPIE -fno-math-errno -ferror-limit=0 -std=c++17 -MD -MT CMakeFiles/TestExec.dir/main.cpp.o -MF CMakeFiles/TestExec.dir/main.cpp.o.d -o CMakeFiles/TestExec.dir/main.cpp.o -c ../main.cpp
../main.cpp:1:10: fatal error: 'quantum/quantum.h' file not found
#include <quantum/quantum.h>
         ^~~~~~~~~~~~~~~~~~~
1 error generated.
ninja: build stopped: subcommand failed.

Not surprising, because:

add_library(${PROJECT_TARGET_NAME} INTERFACE)
set(QUANTUM_DEPENDENCIES Boost::context pthread)
set_target_properties(${PROJECT_TARGET_NAME} PROPERTIES
        INTERFACE_INCLUDE_DIRECTORIES $<INSTALL_INTERFACE:include>
        INTERFACE_LINK_LIBRARIES "${QUANTUM_DEPENDENCIES}"
        INTERFACE_POSITION_INDEPENDENT_CODE ON
        #INTERFACE_SOURCES "$<INSTALL_INTERFACE:include>/${PROJECT_TARGET_NAME}/quantum.h"
)

It seems like the quantum CMake file was never meant to be used without installing...

Okay, no problem: It's a header only library, right? Let's just include the directory.

find_package(Boost 1.72 REQUIRED COMPONENTS context)

add_executable(TestExec main.cpp)
add_subdirectory(quantum)
target_include_directories(TestExec PUBLIC quantum)

target_link_libraries(TestExec PUBLIC Boost::headers Boost::context)

Well, that doesn't work:

Okay, cool, that must be due to me including this project as a subdirectory, right? Let's try with the "official" install path:

set(CMAKE_PREFIX_PATH /data/dev/quantum_install_test/)
find_package(Quantum)

add_executable(TestExec main.cpp)
target_link_libraries(TestExec Quantum::quantum)

ninja: build stopped: subcommand failed.

Nope, that wasn't it.

main.cpp simply includes the quantum header for a start:

#include <quantum/quantum.h>

int main() {
    return 0;
}

Tested on Ubuntu 20.04 with Clang 12.0.1

What am I missing?

[robinchrist]

Update:

There was a
CXX_EXTENSIONS NO

in the CMakeLists as part of my usual boilerplate.
Turns out that's the issue...

Is there a specific reason why non-standard / non-portable C++ extensions are necessary?

[accelerated]

Hi @robinchrist I don't think there's any specific reason for using non-standard extensions. I think this compiler issue should be fixed. Since the copy constructor is explicitly deleted for atomics, the move assignment for the spinlock should be written-out rather than defaulted. If you can work with the CXX_EXTENSIONS flag on for the time being it would be great.

Hi @robinchrist Please try the change in this pull request. We will merge if this fixes the issue.
#152

[robinchrist]

Hi,

Sorry for my later reply, I've been out of office.

Unfortunately, your PR #152 does not yet fix the issue:

I have attached a framework for a simple repro, just make sure you're using Clang as your compiler (Ubuntu clang version 12.0.1-++20210825102835+fed41342a82f-1~exp1~20210825083541.133 for me). The quantum folder contains the contents of safaruqi@36f9da2

mkdir build && cd build && cmake -GNinja .. && ninja

It should be the same on all Linux distributions, given you're using Clang 12 and the CMake with CXX_EXTENSIONS OFF

Thanks for providing the framework above for reproducing the issue. I created a newer build environment with newer clang and am now able to reproduce the errors that you are getting. Will work on fixing them when I get some time next.

Hi @robinchrist Please try the change in pull request #153. This should fix the issue.
