OpenJDK Zero PPC Build on OS X Leopard

[Konstantin Tokarev]

Hi all,

Yesterday I've undertook bootstrapping of bsd-port on my G5. I was unaware about recent discussion of this topic on this list, so I've used instructions from [1, 2] and Google :)

My build scripts (modified version of scripts from [2]) are attached.

My build command:

JAVA_BOOTHOST=192.168.1.2 JAVA_BOOTDIR=/usr/lib/jvm/java-6-sun/ nice make ALLOW_DOWNLOADS=true SA_APPLE_BOOT_JAVA=true ALWAYS_PASS_TEST_GAMMA=true ALT_BOOTDIR=/usr/lib/jvm/java-6-sun HOTSPOT_BUILD_JOBS=1 ANT_HOME=/usr/share/ant ALT_FREETYPE_HEADERS_PATH=/Volumes/Development/Gentoo/usr/include ALT_FREETYPE_LIB_PATH=/Volumes/Development/Gentoo/usr/lib ALT_CUPS_HEADERS_PATH=/usr/include ALT_CACERTS_FILE=/System/Library/Frameworks/JavaVM.framework/Home/lib/security/cacerts LIBFFI_CFLAGS="-I/usr/include/ffi" NO_DOCS=true ZERO_BUILD=true ZERO_ENDIANNESS=big ZERO_LIBARCH=ppc ZERO_ARCHDEF=PPC ZERO_ARCHFLAG=-m32 JAVA_BOOTHOST=192.168.1.2 JAVA_BOOTDIR=/usr/lib/jvm/java-6-sun/

Default gcc and g++ are set to gcc 4.2 provided by Apple.

Compilation of Zero failed twice. I've applied patches [3] and [4], and it was compiled.

When everything was build, I've tried to run java -version. It failed:

/build/bsd-ppc/j2sdk-image/bin/java -help
Error occurred during initialization of VM
java.lang.NullPointerException
	at java.util.Hashtable.put(Hashtable.java:432)
	at java.lang.System.initProperties(Native Method)
	at java.lang.System.initializeSystemClass(System.java:1115)


Questions:

1) How to find out why initialization failed? If debugging with gdb can help, how to rebuild only needed module (Zero VM?) with debugging symbols?
2) Do you have any plans to merge fresh Zero? Backporting of [3] and [4] may not be enoough to make thing working.
