http://curl.haxx.se/docs/http2.html
Build Environment:
Amazon EC2
CentOS 7 (x86_64) with Updates HVM (ami-89634988)
Install some library
# yum -y groupinstall "Development Tools"
# yum -y install libev libev-devel zlib zlib-devel openssl openssl-devel git
Install nghttp2
# cd /var/tmp
# git clone https://github.com/tatsuhiro-t/nghttp2.git
# cd nghttp2
# autoreconf -i
# automake
# autoconf
# ./configure
# make
# make install
Set library search path
# echo '/usr/local/lib' > /etc/ld.so.conf.d/custom-libs.conf
# ldconfig
# ldconfig -p| grep libnghttp2
libnghttp2.so.14 (libc6,x86-64) => /usr/local/lib/libnghttp2.so.14
libnghttp2.so (libc6,x86-64) => /usr/local/lib/libnghttp2.so
Install cURL
# cd /var/tmp
