library path for libjvm.dylib and OpenJDK

[Mahmood Ali]

Greetings,

First, thank you very much for your efforts on porting the OpenJDK to Mac OS X.

First, I have successfully compiled the bsd-port on my machine.
However, I'm having some difficulty running the JVM, when I run the
compiler, I get the following error:

$ build/bsd-amd64/j2sdk-image/bin/java -version
Error occurred during initialization of VM
Unable to load native library:
dlopen(/Users/mahmood/tmp/openjdk-7/bsd-port/build/bsd-amd64/j2sdk-image/jre/lib/amd64/libjava.dylib,
1): Library not loaded: libjvm.dylib
  Referenced from:
/Users/mahmood/tmp/openjdk-7/bsd-port/build/bsd-amd64/j2sdk-image/jre/lib/amd64/libjava.dylib
  Reason: image not found

Setting DYLD_LIBRARY_PATH environment variable seem to fix the problem:

$ DYLD_LIBRARY_PATH=build/bsd-amd64/j2sdk-image/jre/lib/amd64/server
build/bsd-amd64/j2sdk-image/bin/java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-mahmood_2010_01_04_15_39-b00)
OpenJDK 64-Bit Server VM (build 17.0-b05, mixed mode)

Last time I compiled the OpenJDK (around mid december), I didn't need
to initialize that variable.  I noticed that on Nov 20, there was a
change that removed LD_LIBRARY_PATH from the jdk launcher project:

However, I cannot detect when such change was pushed to the bsd-port.
Can you please advice how I should go forward preferably, without
setting DYLD_LIBRARY_PATH env variable?

Also a couple of points:

1. Finding the instructions was a bit tedious, if using Google.
Googling the information returned outdated instructions that required
JIXB.  Luckily, I came across the wiki, and saw the linkage to java
rant instructions
(http://www.javarants.com/2009/11/01/building-openjdk-1-7-0-for-mac-os-x-10-6-snow-leopard/).

2. Can you please elaborate on why "There may be no way to get
pre-built binaries for installation of OpenJDK on Mac OS X."?  How
would that be different from the binaries hosted by Soylatte?  I'm
planning to host my binaries online if possible.

Thank you very much again.

Regards,
Mahmood
