I need to examine the JVM_VARIANT(S) variables and logically I want to do:

Nesting if blocks doesn't work - I need a conjunction, or a way to
define a single variable using a conjunction.

Suggestions?

So I re-discovered the "and" operation

  CLIENT_AND_SERVER := $(and $(findstring true, $(JVM_VARIANT_SERVER)), 
$(findstring true, $(JVM_VARIANT_CLIENT)))
  ifeq ($(CLIENT_AND_SERVER), true)
    # Use the committed jvm.cfg for this 32 bit setup but add
    # minimal if needed
    $(JVMCFG): $(JVMCFG_SRC)
        $(call install-file)
        ifeq ($(JVM_VARIANT_MINIMAL1), true)
          $(PRINTF) "-minimal KNOWN\n">>$(@)
        endif
  else
    $(JVMCFG):
        @$(ECHO) C=$(JVM_VARIANT_CLIENT) S=$(JVM_VARIANT_SERVER) 
BOTH=$(CLIENT_AND_SERVER)

Yet I always execute the else but print:

C=true S=true BOTH=true


I'm stumped! :(

Thanks,
