1895.0. "how to change compile link order" by AOSG::FILTER (Automatic Posting Software - mail to flume::puck) Mon Oct 23 1995 16:30

Subj: 	how to change compile link order

I ran into a problem where if I have the atom kit ATM350, I get undefined
symbols compiling some files.
Greg Lueck says:

	The version of the libmld.a library shipped with Atom contains references
	to routines in the libots.a library.  This library should already be installed
	on your system.  A workaround should be to link in libots.a (-lots) after
	linking libmld.a (-lmld).  You can do this by changing your link line like
	this:

	env - COMP_HOST_ROOT=/ COMP_TARGET_ROOT=/ /usr/bin/cc   -EL \
	    -non_shared  -O2 `genpath   ` -L/usr/lib -L/lib -o pmerge.X \
	    main.o loader.o  -lmld -lots

Where would I change the kernel makefiles so that it always does this?

As a general rule, the kernel build should have NO dependencies on the 
libraries generated during the build. As long as you've defined 
COMP_HOST_ROOT=/ as Greg describes and use the installed libs on the build 
machine, this is OK. This sort of thing is generally done to build an object 
that must run as part of the build but doesn't ship with the product.  Check 
kernel/conf/template*.mk.
