Hi,
OpenJDK fails to build with zero currently on 32 bit architectures.
There's a non-architecture-specific compilation error that I fixed [1].
That makes zero build/run on 64-bit architectures. However, the build
still fails on 32-bit. The error says that a jvm.cfg can not be found
for zero.
The following webrev fixes it:
http://cr.openjdk.java.net/~omajid/webrevs/zero-jvm-config/00/
It creates a jvm.cfg that's identical to the one used for 64-bit [2].
I'm not sure this is the "right" way to fix this as I would think zero
should always just use the jvm.cfg that is in the repository. But the
existing logic makes that awkward. I think what we should have is
something like (I can't recall the right way to express this off the top
of my head):
CLIENT_AND_SERVER := ...
COPY_JVM_CFG_FILE := CLIENT_AND_SERVER == true || BITS == 64 ||
JVM_VARIANT_ZERO == true
ifeq ($(COPY_JVM_CFG_FILE),true)
$(JVMCFG): $(JVMCFG_SRC)
$(call install-file)
else
$(JVMCFG):
$(MKDIR) -p $(@D)
$(RM) $(@)
# Now check for other permutations
...
Your change is less intrusive in the sense that it can't affect the
other JVM variants.
Yeah, I wanted to avoid touching anything else since I cant test all of
these combinations locally. But you are right, the suggested approach is
more readable.
Updated webrev:
http://cr.openjdk.java.net/~omajid/webrevs/zero-jvm-config/01/
That looks good to me.
That aside do you not want to also address zeroshark? Or is that only
64-bit?
zeroshark should work on both 32-bit and 64 bit. That said, there's
likely other problems with it at the moment. I don't see a jvm.cfg file
for shark, so I am not sure which jvm.cfg it is meant to use. I suspect
it also has compilation problems but I haven't attempted building it
recently - it's quite picky about the right llvm version (2.9, last I
checked) and I don't have that handy.
Would it be okay if I were to come back to zeroshark later?
Sure.
Thanks,
David
