->When building an <SPAN
-CLASS="APPLICATION"
->eCos</SPAN
-> configuration the primary target is a single
-library, <TT
-CLASS="FILENAME"
->libtarget.a</TT
->. In some cases it is
-necessary to build some additional targets. For example architectural
-HAL packages typically build a linker script and some start-up code.
-Such additional targets can be specified by a <SPAN
-CLASS="PROPERTY"
->make</SPAN
-> property. Any
-option can have one or more <SPAN
-CLASS="PROPERTY"
->make</SPAN
-> properties, although typically such
-properties only occur in the body of a <TT
-CLASS="LITERAL"
->cdl_package</TT
-> command.</P
-><P
->The <SPAN
-CLASS="PROPERTY"
->make</SPAN
-> property takes a single argument, which resembles a
-makefile rule: it consists of a target, a list of dependencies, and
-one or more commands that should be executed. However the argument is
-not a makefile fragment, and custom build steps may get executed in
-build environments that do not involve make. For full details of
-custom build steps see <A
-HREF="build.make.html#BUILD.CUSTOM"
->the Section called <I
->Custom Build Steps</I
