Arch Linux 64bit, using PKGBUILD in https://aur.archlinux.org/pkgbase/avidemux-git/ (https://aur.archlinux.org/pkgbase/avidemux-git/)
I got an error while building vapoursynth plugin

I found that in glibc 2.23, it will check the C++ version by "__cplusplus"
But in ADM_vsProxy.h:
extern "C"
{
#undef __cplusplus
#include "VSScript.h"
#include "VSHelper.h"
#define __cplusplus
}
There is no need to extern "C". There is no function in the header, they are function pointers.
This one should work:
#include "VSScript.h"
#include "VSHelper.h"
