Hi all,
Does anyone here have any experience/worked with Java applications that use jna
[2] or jffi [3] on DragonFly? I encountered a problem that maybe was solved
already.
I wanted to run most of my work related software on DragonFly. Among those
things is Cassandra[1] itself and some services that connect to it. Everything
runs mostly on the JVM but some of the Cassandra related libraries use native
libs via jna and jffi.
I got jna and jffi to build. But I get an exception when running the cassandra
client (which uses jffi):
mmap returned wrong address: wanted 0x400000, got 0x8f180000
which I comes from /usr/src/libexec/rtld-elf/map_object.c (map_object()). This
is pretty much outside of my domain but maybe some of you tried to do something
similar? If anyone can explain why would mmap be unable to return the correct
address (I’ve read the man page, but it's not obvious to me why it happens in
my case) or can point me in some productive direction, I’d really appreciate it.
Cheers,
Roland
