I'm trying to create a JNI DLL to provide an interface to the GPGME library
and I'm having little success. GPG, GPGME (GPG Made Easy) and my JNI code
all compile cleanly under Cygwin but when I run java to test it, I get the
following:
............................................................
CP1
CP2
CP2.5
CP2.7
Usage: java [-options] class [args...]
(to execute a class)
or java -jar [-options] jarfile [args...]

where options include:

...........................................................
The "CPx" lines above are from my JNI DLL, sprinkled in among the calls to
the GPGME API; apparently java is loading my DLL and running at least part
of it. I've written a standalone C program that uses this same code with no
problem; this seems to happen only when I run it through java. GPGME works
by running the GPG executable in the background -- my best guess is that
this sub-process is exiting improperly or too fast and causing this
assertion.
I'm currently running Cygwin 1.3.18-1, though I've also tested 1.3.17-1,
1.3.16-1 and the 1/9/2003 snapshot; they all behave the same way (cygcheck
output is attached).
Any ideas? Would using the mingw32 options avoid this problem? I've been
unable to link correctly with mingw32 but I'm willing to keep trying if
that's a possible solution. I'd be happy to post the source to my JNI DLL
if that would help (it's very small).
Thanks in advance!
