Thank you Gyan -san, 

I found an old version of libvmaf.h on include.  Then I removed it but same 
error message occurred. But this time, the error is related with linker.  i.e. 
bunch of libvmaf.a(svm.cpp.o) error.
I confirmed it does not occurred in dynamic linking.  Finally, I get answer 
from Google. That is:

Add -lstdc++ to CFLAGS while compiling FFmpeg

It seems to me that vmaf_init() had existed before, so I'm not sure why
this would happen.

I'm afraid thet is it a bug of macOS...


I attached config.log with this message.  Hope someone help me...


Make sure libvmaf.h is current and exists in only one path (no older 
copies elsewhere).

I installed:

2.3.0

I didn't know such a git option... Here is:

So, what's your actual version of libvmaf? Because _after_ commit
06a54a4ec73ea6eb8cec41b7af75367bafb075e0, the requirement was increased
to 2.0.0.

If you're using git anyway, you could do a "git bisect".

It seems to me that vmaf_init() had existed before, so I'm not sure why
this would happen.

Here,  I can find out "vmaf_init", might be cause of issue...

Yes, if it is really a bug, how can we do?

i wonder how that can be given that we are always told here that latest
