In order to build the developers' pack, you need to compile the various DLLs and then call build_wpdpack.bat This batch file, in turn, calls the four batches - create_includes.bat creates the include folder - create_lib.bat creates the lib folder - create_examples.bat copies the examples folder to the developers' pack. The examples can be compiled only under the developers' pack folder. - create_docs.bat calls createdoc.bat to create the documentation (via doxygen), and then copies the generated files under the developers' pack folder. The syntax for the various scripts is winpcap_folder developer_folder winpcap_folder The winpcap sources folder. It is defaulted to .\ developer_folder The developers' pack folder. It is defaulted to .\wpdpack. HINT: just call build_wpdpack.bat without any parameter!
