Re: [avr-gcc-list] FIXED: Flags to use in Building a Library

[User Tomdean]

I found a work around.  I use FreeBSD.  I include bsd.prog.mk in all
my Makefiles, it eliminates a lot of extra stuff.  The downside is I
have to provide bsd.prog.mk to anyone who wants to use my Makefiles.
Since it is open source, no problem.

I put bsd.lib.mk in my Makefile.  It seems to use the same commands
except for actually building the library.  And, I had to read a LOT of
make scripts to get there.  After jumping thru a lot of hoops, I had
to put in a strange set of commands to make sure bsd.lib.mk had all
the tools.  Like, for example, lorder, which uses nm.  The FreeBSD nm
is looking for

      ELF 32-bit LSB relocatable, Intel 80386, version 1 (FreeBSD), not stripped

while avg-gcc produces

      ELF 32-bit LSB relocatable, version 1 (SYSV), not stripped

So, I had to force lorder to use avr-nm.  This means it has to be in
the shell environment.  No way to get there from make.  All I know how
to do is force an error if NM is not set to avr-nm in the shell
environment.

The final Makefile is below.
