makefile question

[Hartmut Brandt]

Hi,

I'm preparing an update for bsnmp and have the following problem:

In libbsnmp a header file is created during the build process, which
obviously ends up in the object tree. Now I need to include this file
when building the daemon and modules from usr.sbin. I have the feeling
that doing

CFLAGS += -I../../../lib/libbsnmp/libbsnmp

in usr.sbin/bsnmp/bsnmp to reach into the library object directory doesn't
look right.

Or is this the right way to do this?

Check out usr.bin/w/Makefile, it uses a module from bin/ps.

I think he said it's a generated header.

Looks like share/mk/src.sys.obj.mk now sets OBJTOP
or at least OBJROOT even for non-meta-mode build.

So -I${OBJTOP}/lib/libbsnmp/libbsnmp should probably work.

Oh, you're right. I missed that detail.
