My Mac OS system is: OS X Yosemite version 10.10.5.
And its openssl version is 0.9.8zg.
Now I want to install an nghttp2 tool, and it requires openssl>=1.0.1.
So I try brew update and brew install openssl.
After that I use command: openssl version
,it shows:OpenSSL 1.0.2l 25 May 2017
.
But when I go to nghttp2 directory and run the ./configure
command,it still shows:
configure: Requested 'openssl >= 1.0.1' but version of OpenSSL is 0.9.8zg
.
I am confused, why the latest version not used but still use the old one?
