gcj on osx questions

[Mohan Embar <gnustuff at thisiscool dot com>]

Hi All,

This is a two-part question. I have a cute little used Mac Mini
sitting on ny dining room table that I'm trying to get gcj-built
executables to work on.

First of all, I needed to make a change to natPlainSocketImplPosix.cc
to get sockets working:

void
gnu::java::net::PlainSocketImpl::bind (::java::net::InetAddress *host, jint lport)
{
  union SockAddr u;
  struct sockaddr *ptr = (struct sockaddr *) &u.address;
  jbyteArray haddress = host->addr;
  jbyte *bytes = elements (haddress);
  int len = haddress->length;
  int i = 1;

+ memset (&u, 0, sizeof (u));
  if (len == 4)

I did this against a 4.02 snapshot but am not sure where to
go from here since the trunk is already at 4.2.

The second question has to do with this:

http://gcc.gnu.org/ml/java/2005-03/msg00053.html

I'd like to get JNI libraries built against Apple's JDK to be loaded
by libgcj, but Andi remarked that Apple changed the structures in jni.h.
Bryce commented that through #ifdefs, it might be possible to change libgcj's
jni.h to make it compatible with Apple's.

My question is: How does one go about doing this? Are we allowed to look at the
Apple headers or does doing so taint us?
