Compile error on ArchLinux at FpsControls.cpp.o also after ad3d542 about ishiiruka

[SirMangler]

std::lerp, I was worried that might not compile on Linux. Luckily cmath seems to contain lerp for Linux. This commit should fix the other problems too,

Tried but i have the same

You may need to compile with a later version of C++. std::lerp was only added in C++20. I'll look into this more later, there may be a built in function for it in Dolphin like there is for Qt.

Tried with clang++ but it stop immediately with error

I found this issue on Dolphin-emu bugtracker : Emulator Issues #12032

[SirMangler]

Trouble is, this is the PrimeHack-Ishiiruka repository, Ishiiruka is a fork of dolphin which is pretty old by a few years. You'd have to talk to the maintainers for Ishiiruka about stuff not relevant to PrimeHack.

Have you ensured you're compiling with C++20?

[SirMangler]

This should resolve the problem:

Happy new Year !

I'm using the latest version of GCC & CLANG
I've checked on CMakeLists.txt and found that it check for CXX17 and pass -std=c++17.
For C++20 shouldn't it check the CXX20 support and pass -std=c++20 parameter ?

Ok now i don't have anymore problem on FPSControl.cpp.o but it give me another error :

Another info that i forgot to report : i use GCC 10.2 that is the latest version on Linux.
The G++20 std::lerp was introduced with GCC9 so i'm full compliant with it (see the changelog here )
So i think that the CMakeFile don't pass the correct flag for C++20 when compiler different that MSVC is found
