Re: project in multiply directories

[Alberto Luaces]

Hello Maxim,

I recommend you to read the tutorial at 
http://www.lrde.epita.fr/~adl/autotools.html . It addresses all of your 
questions. See below:

You can refer to any subdirectory in the source with 
$(srcdir)/your_subdirectory. For including purposes you'd use -
I$(srcdir)/directory.

> 2) all source files will be compile from all subdirectories

You can put full paths to these files in your Makefile.am or create one 
Makefile.am for every subdirectory and refer each file by its name. See 
SUBDIRS in the tutorial.

This is covered on page 92 of the tutorial, "Conditinals: usage"

You can link with system libraries or with libraries created in your own 
project.
