Re: [Jepp-users] Problem with JRE 1.6 (64 bit) + JEP (2.4)

[Prasanth N. <nar...@gm...>]

Hi Mike,

I've run pexports (for jvm.dll) & was able to generate jvm.def
But when i use dlltool to generate import library (dlltool -D jvm.dll -d
jvm.def -l jvm.a), it creates jvm.a with 0kb (nothing in it).

Can you help me with this.

Thanks,
Prasanth Narra
