[Newbie question] Strange errors trying to build the JDK

[David Holmes]

Interesting - there is no actual error report in the log. Only this:

lib/JvmMapfile.gmk:141: recipe for target 
'/home/zambonifofex/jdk/build/linux-x86_64-normal-server-release/hotspot/variant-server/libjvm/symbols-objects' 
failed

Looking at the gmk file we have:

$(JVM_OUTPUTDIR)/symbols-objects: $(BUILD_LIBJVM_ALL_OBJS)
	$(call LogInfo, Generating symbol list from object files)
	$(CD) $(JVM_OUTPUTDIR)/objs && \
	  $(DUMP_SYMBOLS_CMD) | $(NAWK) $(FILTER_SYMBOLS_AWK_SCRIPT) | $(SORT) 
-u > $@

I'd have to suspect one of the command variables is not set. I suspect 
the actual error text may be redirected to the symbols-objects file, but 
unfortunately that has been deleted by 'make'.

Check the generated spec.gmk file for the value of DUMP_SYMBOLS_CMD and 
NAWK.
