Is there a way to compile a C++ file in the Wiced SDK ? I tried a simple application test that includes and I get a lot of errors.

I tried on macOS and Linux and the errors are the same. Any idea ?

Thank you

Try  in  sdk3.7.0 (looks same in 4.0) file  WICED-SDK\tools\makefiles\wiced_toolchain_ARM_GNU.mk

make small change  add COMPILER_SPECIFIC_SYSTEM_DIR_CXX and change CXX

ifeq ($(COMPILER_SPECIFIC_SYSTEM_DIR),)

COMPILER_SPECIFIC_SYSTEM_DIR := -isystem $(TOOLCHAIN_PATH)../../include -isystem $(TOOLCHAIN_PATH)../../lib/include -isystem $(TOOLCHAIN_PATH)../../lib/include-fixed

COMPILER_SPECIFIC_SYSTEM_DIR_CXX := $(TOOLCHAIN_PATH)../../include $(TOOLCHAIN_PATH)../../lib/include $(TOOLCHAIN_PATH)../../lib/include-fixed

endif

CC       = "$(TOOLCHAIN_PATH)$(TOOLCHAIN_PREFIX)gcc$(EXECUTABLE_SUFFIX)" $(COMPILER_SPECIFIC_SYSTEM_DIR)

CXX      = "$(TOOLCHAIN_PATH)$(TOOLCHAIN_PREFIX)g++$(EXECUTABLE_SUFFIX)" $(COMPILER_SPECIFIC_SYSTEM_DIR_CXX)

This change help compile C++ files for us.

Can wiced team approve this fix?

Which sdk version you used?

With 3.5.2 no problems. With 3.7.0 was problem in makefile. Need do some correction.

I not interesting in wiced4, because removed support for freertos-lwip. But think, that same makefile bug, like 3.7.0 ...   I am not at workplace, so what need change, i will append later.
