Problems with Standard Make Tutorial

I’m running Momentics on a Windows platform. Here is my makefile:

all: test

INCLUDES = -IC:\QNX630\target\qnx6\usr\include\cpp

clean:

-rm main.o test.exe test

test: main.o

QCC $(INCLUDES) -g -o test main.o

main.o: main.cpp

QCC $(INCLUDES) -c -g main.cpp



Here is my source file:

#include

#include

int main()

{

string yourName;


cout << "Enter your name: ";

cin >> yourName;

cout << "Hello " + yourName << endl;


return 0;

}

I also have the include path added via the Project Properties page.
However, when I attempt to build the project, the IDE cannot find the
include files. I get the following response:

make all

Any suggestions as to how I’m supposed to get the IDE to be able to find the
required header files?



Thanks,

Don,

It looks as though your Borland “make” executable is higher in your PATH
environment variable than the QNX one. Make sure that $QNX_HOST/usr/bin
is before wherever the Borland version is.

Why isn’t the compiler complaining about not being able to find the
headers? I looks almost as though your code were missing the #include
lines…

They are there. See previous post for the source file. It is essentially
the little file used in the Standard Make tutorial for Momentics. Maybe my
include path is wrong. I used:

INCLUDES = -IC:\QNX630\target\qnx6\usr\include\cpp

which has both string and iostream in it, but there is also

C:\QNX630\target\qnx6\usr\include\c++\3.3.5 or
C:\QNX630\target\qnx6\usr\include\g+±3

I’m not sure which one I’m supposed to use.

Adding “using namespace std;” seems to allow the compiler to see the include
files, but then I get a whole host of other errors…

Does this mean I am using the wrong include files?

Without the “using namespace std;” the compiler saw the include files,
too; it just needed a clue that what your code refers to as “string” is
what the header defines as “std::string”.

Or wrong libraries, perhaps?

You need to tell qcc that your objects are C++ objects. Add -lang-c++ to your qcc lines.

You shouldn’t need to add the includes, they are automatically added.

You don’t need to add a -I option for the standard C++ headers, the
compiler knows where to find them… remove that INCLUDES line
completely and it should still work.
