I read the description of the dh_nativejar command:
it can compile jar to native binary.
But what about pljava.so, using C for JNI code?
Could you tell me precisely how to modify the makefile for pljava.so
in order to
solve this problem.
I can add the problem is not specific to amd64 but occurs also
on Debian Etch i386:
I have the same problem with the following configuration:
uname -a
Linux acoeur-e 2.6.18-3-k7 #1 SMP Mon Dec 4 17:23:11 UTC 2006 i686 GNU/Linux
