How to compile obj-c and c++ together

[Lucas Samaruga]

Hello

I'm trying to learn the gnustep make file system in osx.

I want to mix obj-c and c++ code, I found some posts in the list and suppose it's possible,

but the problem is that make don't compiles the c++ files (?)

Any help or appointment to a tutorial is appreciated,

I read the manual but ins't a tutorial and I can't find one that covers the system beyond the very basic.

this are the makefile and the terminal output

# GNUmakefile

include $(GNUSTEP_MAKEFILES)/common.make

APP_NAME = PanelTest

PanelTest_OBJCC_FILES = source.mm

PenelTest_CC_FILES = testMake.cc

include $(GNUSTEP_MAKEFILES)/application.make

# end of GNUmakefile

terminal output:

This is gnustep-make 2.4.0. Type 'make print-gnustep-make-help' for help.

Making all for app PanelTest...
