[Gems-users] Patching GEMS for SIMICS 4.2 and compiling Ruby

[mostafa m hassan <mostafa.m.hassan@xxxxxxxxxxxxx>]

Hi,

I have installed simics 4.2.8 and  gems release 2.1.........then I patched gems using quilt utility
my compiler version is 4.6.1 , so I had to modify some values in makefile.common........another thing is that after patching I could not find a section in the makefile.common for $(simics_version) = 4.2...so I assumed I should add this section:
ifeq ($(SIMICS_VERSION),4.2)
  SPECIAL_FLAGS += -DSIMICS42
  SIMICS_ROOT := $(SIMICS_INSTALL)
  SIMICS_EXEC_ROOT := $(GEMS_ROOT)/Simics-workspace      #my workspace inside Gems path
  SIMICS_INCLUDE_ROOT := $(SIMICS_INSTALL)/src/include      #this was -->  #$(GEMS_ROOT)/../install/simics-model-builder-4.2.30/src/include    and I couldnot find simics-model-builder-4.2.30 in the installation path

  SIMICS_API = latest
else

I am trying now to compile Ruby but I get so many circular dependencies like below :
make: Circular x86-linux <- x86-linux dependency dropped.
make: Circular /generated/MOSI_SMP_bcast/obj/attrparse.o <- x86-linux dependency dropped.
make: Circular x86-linux <- x86-linux dependency dropped.
make: Circular /generated/MOSI_SMP_bcast/obj/attrlex.o <- x86-linux dependency dropped.
make: Circular x86-linux <- x86-linux dependency dropped.
make: Circular /generated/MOSI_SMP_bcast/obj/initvar.o <- x86-linux dependency dropped.
make: Circular x86-linux <- x86-linux dependency dropped.
make: Circular /generated/MOSI_SMP_bcast/obj/confio.o <- x86-linux dependency dropped.

and at the end I got an error:
../common/Makefile.common:184: *** wrong rule.  Stop.

to see more details about the error, I commented these lines in makefile.common:
#.l.c:
#    $(error wrong rule)

#.y.c:
#    $(error wrong rule)
 
and I got this error:
bison --verbose --defines ../common/ioutil/attrparse.y
mv -f y.tab.c attrparse.c
mv: cannot stat `y.tab.c': No such file or directory
make: *** [attrparse.c] Error 1

could anyone help me please ?.....I believe that the patching operation is not enough to get it to work, I believe that so many modifications should be made to so many files after the patch!!


Thanks alot for any help offer
