|Linux| GNU autotool
If you want to porting any library from the distribution to another one,
you should learn GNU autotool firstly.
From porting libqmi, we can learn this fact.
Step 1: install the following libraries.
autotools-dev
libev-dev
autoconfig
automake
autoconf-archive
libtool
Step 2: enter the libraries’ folder
which included configure.ac, Makefile.am
./configure //in fact, doing autoconf
make
make install
Explanation of files:
configure.ac: input file for Autoconf.
Makefile.am: input file(s) for Automake.
