Hello,

yes, I'm using automake.

I put the sub-objects into my AM_INIT_AUTOMAKE. It works like you
explained. Thanks. But why does it's not the default behavior ?

I wanted to have my source directory cleaner: all .o files, plus .lo
files, plus .Plo.... This makes directories unreadable....

Furthermore I noted that .o files are twice for one source file:

$ find . -name "main.*" -ls
4964623    4 -rw-r--r--   1 michel   users         266 fév  4 10:22 ./main.lo
4440187    8 -rw-r--r--   1 michel   users        5268 fév  4 10:22 
./.libs/main.o
4394955    8 -rw-r--r--   1 michel   users        4544 fév  4 10:22 
./.deps/main.Plo
4964367    8 -rw-r--r--   1 michel   users        5000 fév  4 10:22 ./main.o
10371366    4 -r--r--r--   1 michel   users         804 déc  2 18:41 ./main.c

I do not really understand here. Two main.o !

Cheers,
Michel
