Extension makefiles are makefiles to be run by <filepath>make.exe</filepath> (the GCC make utility) or <filepath>nmake.exe</filepath> (the Microsoft make utility). They must contain certain make targets. During build activities, <filepath>abld</filepath> will call the target corresponding to the build activity that is being carried out. This will then execute whatever commands your makefile specifies for that target. </p> <p>The following table lists the required make targets: </p> <table id="GUID-058134AF-E473-577E-B6E8-6309B859E5D7"><tgroup cols="2"><colspec colname="col0"/><colspec colname="col1"/><tbody><row><entry><p> <b>Target</b> </p> </entry> <entry><p> <b>Corresponding abld command</b> </p> </entry> </row> <row><entry><p> <codeph>makmake</codeph> </p> </entry> <entry><p> <codeph>makefile</codeph> </p> </entry> </row> <row><entry><p> <codeph>freeze</codeph> </p> </entry> <entry><p> <codeph>freeze</codeph> </p> </entry> </row> <row><entry><p> <codeph>lib</codeph> </p> </entry> <entry><p> <codeph>library</codeph> </p> </entry> </row> <row><entry><p> <codeph>cleanlib</codeph> </p> </entry> <entry><p> <codeph>tidy</codeph> </p> </entry> </row> <row><entry><p> <codeph>clean</codeph> </p> </entry> <entry><p> <codeph>clean</codeph> </p> </entry> </row> <row><entry><p> <codeph>final</codeph> </p> </entry> <entry><p> <codeph>final</codeph>.
