Windows: jpen-2.dll

1. Download the source zip file and unpack it. You will have a new directory called jpen-2-150301.
2. Download the wintab development kit and unpack it in a temp directory. Move the unpacked directories to the locations:
   • Move INCLUDE to jpen-2-150301\c\windows\INCLUDE . So that you have jpen-2-150301\c\windows\INCLUDE\PKTDEF.H and all the other files.
   • Move LIB\I386 to jpen-2-150301\c\windows\lib . So that you have jpen-2-150301\c\windows\lib\WINTAB32.DEF and all the other files.
3. Install the JDK (1.5.x) , and MinGW-5.1.3 (my installation has following components: runtime=mingw-runtime-3.11.tar.gz, w32api=w32api-3.8.tar.gz binutils=binutils-2.15.91-20040904-1.tar.gz, core=gcc-core-3.4.2-20040916-1.tar.gz, gpp=gcc-g++-3.4.2-20040916-1.tar.gz).
4. Open a command window, go to your prepared jpen-2-150301\c\windows directory, and run:

   > c:\mingw\bin\gcc -Wall -c -mrtd -D_JNI_IMPLEMENTATION 
    -Ic:\javaSdk\include -Ic:\javaSdk\include\win32 *.c

   Replace c:\mingw and c:\javaSdk according to your environment (c:\mingw is the MinGW installation directory and c:\javaSdk is the jdk installation directory). Finally, run:

   > c:\mingw\bin\gcc -Wall -Wl,-kill-at -shared  
   -o jpen-2.dll *.o -Llib -lWintab32

   and you will get jpen-2.dll.
