Build error on windows with clang #258

Closed fspindle closed 8 months ago

fspindle commented 12 months ago

I'm unable to build the project on windows with clang coming with Visual Studio 2022.

To reproduce the build error:

$ git clone https://github.com/ermig1979/Simd
$ cd Simd
$ mkdir build
$ cd build
$ cmake ..\prj\cmake -G "Visual Studio 17 2022" -T "ClangCl" -A "x64"
$ cmake --build . --config Release

It produces the following error:

clang-cl : warning : unknown argument ignored in clang-cl: '-fPIC' [-Wunknown-argument] [C:\temp\Simd\build\Simd.vcxpro
j]
clang-cl : warning : unknown argument ignored in clang-cl: '-std=c++11' [-Wunknown-argument] [C:\temp\Simd\build\Simd.v

Hi!

There is no possibility to compile Simd sach way yet.

I fixed it by moving the deprecated macro to before the inline macro.

razaqq commented 8 months ago

Yes please change the macro order from SIMD_API SIMD_DEPRECATED to SIMD_DEPRECATED SIMD_API. The standard says explicitly In declarations, attributes may appear both before the whole declaration and directly after the name of the entity that is declared, in which case they are combined.

Hi. I chenged the macro order from SIMD_API SIMD_DEPRECATED to SIMD_DEPRECATED SIMD_API.

Perfect, you can close this then
