Please place libbz2.lib and bzlib.h in $(ABI_ROOT)/../libs/bzip2 libbz2.lib will need to be generated and copied to this location for the Win32 plug-in build of bz2abw to work. bzi2 and libbzip2 can be found at: http://sourceware.cygnus.com/bzip2/index.html Get the source code, follow the instructions for building. We normally want the static libs unless you will place the generated dll in the system path. Alternately, Include directories may be created or mapped. This means that either copy bzlib.h to VC98/include/bzlib.h.h Or define those as part of vcvars32.bat INCLUDE search routines. Place in this directory libbz2.lib And now you are set to build this plug-in. from the bz2abw directory use make under the cygwin system for abiword.
