ELDK/DENX: doesn't find iostream-lib when linking
Peter,
you should use g++ as compiler front end when compiling C++ programs
> compiler = ${CROSS_COMPILE}g++

I asked for the COMMANDS used, not for a Makefile. A log of the build

You are using the wrong compiler. GCC is a C Compiler, but you are
trying to compile and link C++ code. GCC does not know how to handle
this. Please use a C++ compiler - i. e. "g++" - instead.

Unix is like a toll road on which you have to stop every 50 feet to
pay another nickel. But hey! You only feel 5 cents poorer each time.

ELDK/DENX: doesn't find iostream-lib when linking
I use a makefile with dependencies:
--
# Makefile for simple test program
# The CROSS_COMPILE is set globally, as well as ELDK gcc-paths
compiler = ${CROSS_COMPILE}gcc
simple_server_objects = ServerSocket.o Socket.o simple_server_main.o
simple_client_objects = ClientSocket.o Socket.o simple_client_main.o
all : Socket ServerSocket simple_server_main simple_server ClientSocket
simple_c
lient_main simple_client
simple_server: $(simple_server_objects)
$(compiler) -o simple_server $(simple_server_objects)
simple_client: $(simple_client_objects)
$(compiler) -o simple_client $(simple_client_objects)
#ppc_gcc dependencies, added for compiling with ppc only!!
Socket:
$(compiler) -o Socket.o -c Socket.cpp
ServerSocket: Socket.o
$(compiler) -o ServerSocket.o -c ServerSocket.cpp
ClientSocket: Socket.o
$(compiler) -o ClientSocket.o -c ClientSocket.cpp
simple_server_main: ServerSocket.o
$(compiler) -o simple_server_main.o -c simple_server_main.cpp
simple_client_main: ClientSocket.o
$(compiler) -o simple_client_main.o -c simple_client_main.cpp
clean:
rm -f *.o simple_server simple_client
The program itself is using and other STL libs with
namespaces in use.
It compiles for i686 on my host machine.
BUT I had to change the Makefile!!! (that is why I posted it)
The dependencies starting from "gcc-ppc" dependencies are added.
Are they defined wrong?

Change the gcc to g++ if you use STL and C++ programs.
