i did not know about gcj. i guess i missed that somehow? thanks for the tip.

my command line right now is:

gcj -D__int64="long long" -shared -I C:\Apps\Java\jdk1.6.0_05\include
-I C:\Apps\Java\jdk1.6.0_05\include\win32 -I C:\Users\usmsci\My
Documents\shapefiles\shapelib-1.2.10\shapelib-1.2.10 -I
C:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win -L
c:\Users\usmsci\My Documents\shapefiles\shapelib128_bin_win
fileName.cpp -o libShapeData.dll c:\Users\usmsci\My
Documents\shapefiles\shapelib128_bin_win\shpopen.o c:\Users\usmsci\My
Documents\shapefiles\shapelib128_bin_win\dbfopen.o

the error i get is: gcj: cannot specify -D without --main  what do i
need to do to remedy this? thanks!!!

i dont have a main function in my .cpp file. i assume thats what its
complaining about? i am using the -D option otherwise i would endless
complaints about jlong not having a type and a bunch of other related
stuff.
