Summary: build targets with custom make file wrong
Product: kdevelop
Version: CVS
Platform: unspecified
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
AssignedTo: kdevelop-devel at kdevelop.org
ReportedBy: jonsmirl at yahoo.com
Version: CVS (using KDE Devel)
This is makefile from the DRI project. The build targets menu is picking up the lines with 'include::'. I don't think it should be doing that.
# Makefile -- For the Direct Rendering Manager module (drm)
#
# Based on David Woodhouse's mtd build.
#
# Modified to handle the DRM requirements and builds on a wider range of
# platforms in a flexible way by David Dawes. It's not clear, however,
# that this approach is simpler than the old one.
#
# The purpose of this Makefile.linux file is to handle setting up everything
# needed for an out-of-kernel source build. Makefile.kernel contains
# everything required for in-kernel source builds. It is included into
# this file, so none of that should be duplicated here.

#
#
# By default, the build is done against the running linux kernel source.
# To build against a different kernel source tree, set LINUXDIR:
#
# make -f Makefile.linux LINUXDIR=/path/to/kernel/source
#
# To build only some modules, either set DRM_MODULES to the list of modules,
# or specify the modules as targets:
#
# make -f Makefile.linux r128.o radeon.o
#
# or:
#
# make -f Makefile.linux DRM_MODULES="r128 radeon"
#
