[Babel-users] babeld building and binary size

[Matthieu Boutier]

Hi,

A first step could be to remove the "-g" from CFLAGS.  Default is "-Os -g".

On my desktop computer (debian 64bits, gcc), commit 9be552feda7f:

$ make clean > /dev/null; make CFLAGS="-Os -g" > /dev/null; du -h babeld
460K	babeld
$ make clean > /dev/null; make CFLAGS="-Os" > /dev/null; du -h babeld
132K	babeld

The weird part, "-O0 -g" is smaller than "-Os -g":

$ make clean > /dev/null; make CFLAGS="-O0 -g" > /dev/null; du -h babeld
332K	babeld

Other results:

$ make clean > /dev/null; make CFLAGS="-O0" > /dev/null; du -h babeld
188K	babeld
$ make clean > /dev/null; make CFLAGS="-O3" > /dev/null; du -h babeld
196K	babeld
$ make clean > /dev/null; make CFLAGS="-O2" > /dev/null; du -h babeld
156K	babeld
$ make clean > /dev/null; make CFLAGS="-O1" > /dev/null; du -h babeld
148K	babeld

You should find the corresponding makefile in the lede repos.
