Auto Generate Makefile with Autoconf and Automake

Writting an Makefile is too hard for someone who program with c/c++ language under linux,especially for large project.Let's face it,do not type the source file to the Makefile template one by one any more.Here is a small HowTo to generate an Makefile automatically using autoconf and automake tools.Follow me right now.

Step 0
Make sure these tools live in your system.

1 autoconf
2 automake
3 m4
4 perl
5 libtool(if you need shared libs)

Step 1
1 Autoscan

    cd ~/test/autoMakefile
    autoscan

2 Modify the configure.scan like this

3 Rename configure.scan to configure.in

Step 2
Aclocal

Step 3
Autoconf

Step 4
Edit Makefile.am

Step 5
Automake --add-missing

Figure it out with autoheader(generate file config.h.in)

And then redo automake.

Step 6
Run ./configure to generate Makefile

checking for GNU libc compatible malloc... yes
checking for ftime... yes
checking for gethostbyname... yes
checking for memset... yes
checking for select... yes
checking for socket... yes
checking for strtoul... yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: executing depfiles commands

Step 7
Compile the project,type make

Step 8
Make Makefile perfectly.

As you can see,make command generate the object under project root directory.We move them to their source directory by modify the Makefile.

Add add these lines to the clean tag

    @rm -f example/rtsp_example.o
    @rm -f lib/rtsp.o
    @rm -f lib/rtsp.o
