When using Facebook Folly in my code, g++ could not find some header

Question

I have installed Facebook Folly from source, and some headers were copied to /usr/local/include/folly automatically.

Then I am using #include "folly/Conv.h" in my code, but when I compile, I meet a error: could not find folly/CpuId.h .

I find that CpuId.h is not in /usr/local/include/folly but it is in the directory where I downloaded Folly.

My questions:

1. Why doesn't Folly copy all headers to /usr/local/include/folly when I installed it?
2. How can I know my Folly version? I just downloaded the folly-master.zip without git some day before installing it.

Answer 1

why does not folly copy all header to /usr/local/include/folly when I installed ?

Some version is not so good as others. I met with the same problem too. It's quite stable now.

how can I know my folly vertion? I just download the folly-master.zip without git someday before.

It has several releases .

If you are using Gentoo Linux, you may employ my folly library overlay .
