CMakeLists.txt problem on linux + clang

[mipac]

help !

I try to build kfr_dft with clang 7 on debian 9 I get : error: no type named 'align_val_t' in namespace 'std' inline static void* operator new(size_t size, std::align_val_t al) noexcept

it seems to point to the gcc headers ...

how can I do? cmake detect clang 7 OK, but include seems to point in bad place ...

could someone post a "tuto" about compiling kfr_dft on linux ?

thanks

ok, I found that recipe that works on debian 9 with: cmake version 3.13.2 llvm/clang/libc++ version 7 from apt

I need to add that line in CMakeLists.txt

project(kfr CXX)

set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(CMAKE_CXX_EXTENSIONS ON)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -v -stdlib=libc++ -std=c++17") ...

"-v" is just to verbose and debug the problem... you can omit it

you can add -DCMAKE_CXX_FLAGS="-stdlib=libc++ -std=c++17" to cmake arguments to keep CMakeLists.txt as is.

hope that could help someone, or the dev team to modify cmakelists.txt to make it easier for the mass ;)

thanks
