vxWorks-Workbench 6.8 unresolved C++ symbols

I made a vxWorks project, using Downloadable Kernel Module in vxWorks. It builds perfectly, but when I download it into the simulation environment it will complain about unresolved C++ libraries.

This is the only code

#include <iostream>

int helloworld()
{
  std::cout << "HELLO WORLD\n";
  return 0;  
}

I will get unresolved std::uncaught_exception(), __cxa_end_catch, __gx_personality_v0, std::cout.....etc.

Anyone have had this problem ? It seems like it's just not including the C++ libraries...if so, anyone knows how to add this ?

Thanks.

This is due to your vxworks image configuration. From the vxworks image project you should add cpp components entirely.

Are you using the standard simulator? If so, confirm if the kernel Image has all c++ components included.

To do so, create a new kernel Image project, and in the kernel configuration include the iostream component. Although there are other ways, but this should solve the issue.

Better use kprintf, for having a screen output as it is the standard practice.

Normally, in "Build Tools" tab of the project properties the "Linker" dropdown list should bring the following parameters for C++ DKM for PPC project: 

echo "building $@";
rm -f %OutFile%;
ddump -Ng %Objects% %Libraries% | tclsh $(WIND_BASE)/host/resource/hutils/tcl/munch.tcl -c ppc -tags $(VSB_DIR)/tags/ppc/PPC32/common/dkm.tags > $(OBJ_DIR)/ctdt.c;
%ccompilerprefix%
$(TOOL_PATH)
dcc %DebugModeFlags% $(CC_ARCH_SPEC) -Xdollar-in-ident -Xforce-declarations $(ADDED_CFLAGS)
%Includes% $(ADDED_INCLUDES) -DCPU=$(CPU) -DTOOL_FAMILY=$(TOOL_FAMILY) -DTOOL=$(TOOL) -D_WRS_KERNEL  -D_VSB_CONFIG_FILE=\"$(VSB_CONFIG_FILE)\" $(DEFINES) -o $(OBJ_DIR)/ctdt.o -c $(OBJ_DIR)/ctdt.c;
%linkerprefix% $(TOOL_PATH)dld -tPPCFH:vxworks68 -X -r5 %ToolFlags% -o %OutFile% $(OBJ_DIR)/ctdt.o
%Objects%
%Libraries% $(LIBPATH) $(LIBS) $(ADDED_LIBPATH) $(ADDED_LIBS) && if [ "$(EXPAND_DBG)" = "1" ]; then plink "$@";fi

Check if this is wat you have in your project. Especially around the %Libraries% part.

P.S. Nevermind the formatting - it is just for readability.
