I download the source from github:https://github.com/nghttp2/nghttp2. and install with step :
$ autoreconf -i
$ automake
$ autoconf
$ ./configure
$ make
Every step is OK,but I can not use it。
nghttp
-bash: nghttp: command not found
But ,I install nghttp2 on Ubuntu 14.04 successfull!
sudo yum groupinstall "Development Tools"
sudo yum install libev libev-devel zlib zlib-devel openssl openssl-devel git
git clone git@github.com:tatsuhiro-t/nghttp2.git //or download and unzip
cd nghttp2
autoreconf -i
automake
autoconf
./configure --prefix=/usr/local/nghttpx --enable-app
make
sudo make install
