Errors when including EWL C++

derekdrost — Thu, 16 May 2013 15:00:29 GMT

Hello everyone. I am working with CodeWarrior 10.3, MQX 4.0. I am working on a c++ project, however, when I add the C++ Folder to my includes, I get errors inside the char_traits file. Which is located inside the C++ includes in the MQX Folder.

Picture is attached which may help.

Anyone have any ideas?

Thanks for the help!

Hi Derek,

Difficult to say what is the problem.

What do you mean by " when I add the C++ Folder to my includes" ?

You're using CodeWarrior 10.3, MQX 4.0.how are you created the project ?

We need more info to try to reproduce the problem on our side.

Regards

Pascal

Hi Pascal,

I add “${MCUToolsBaseDir}/Arm_EABI_Support/ewl/EWL_C++/include” into the c section under properties->c/c++ General ->Paths and Symbols.

I started the project using the cplus example, then I would include “vector.h” in my project. I am then able to use the vector object, however, I get around 45 errors inside of the char_traits file located inside of the C++ include folder.

Thank you for the reply,

Derek

Derek,

When you create a project for Kinetis there are some options proposed in project Wizard.

For instance compiler type: GCC or Freescale.

I've created an example using Freescale compiler.

in the project Properties under C/C++ Build ¦ Settings ¦ Librarian, you select the EWL libraries.

On my side I've already the "${MCUToolsBaseDir}/Arm_EABI_Support/ewl/EWL_C++/include” defined in properties->c/c++ General ->Paths and Symbols.

Now I added # include "vector.h"

and it's working.

I can build the project without problem.

I will try to send you the example I've created.

Derek,

I added my example project named test_bis.zip.

Have a look at your original question.

Pascal,

Alright I'll give it a look. Let you know if I get it working.

Thanks again!

Well I can run your program no problem, however I am having problems getting my current project to either:

1. Take the settings you have and let me use it in my current project.

2. Put my project into yours.

I attached my project, any help would be really appreciated.

Thank you so much,

Derek

Hi Derek,

I've performed some tests on my side and probably you've created the project without C++.

when the C++ is not selected at project wizard, the Paths and Symbols contains:

${MCUToolsBaseDir}/ARM_EABI_Support/ewl/EWL_C/include only.

whereas the C++ options project includes

${MCUToolsBaseDir}/ARM_EABI_Support/ewl/EWL_C/include

${MCUToolsBaseDir}/ARM_EABI_Support/ewl/EWL_C++/include

some other settings should be added when the project is defined as C++ by default.

this seems to be the cause of the problem.

If you need other info, don't hesitate to re-contact me.

Good morning Pascal,

I know what you mean, the problem I am having is:

1: Converting my project into a C++ project, by changing the project properties and other settings.

2: Starting out with a new C++ project, then adding my code and changing settings to get the right debugger, etc..

If you could help me figure out a way to do either that would be great. I've been trying to get this to work the last couple days and I've hit a wall.

Thank you for your help!

Ok so, you need to convert the project sent which was created as C project to a C++ one.

I need to perform some tests on my side to determine/find all settings to change.

The better was is to use a new project with wizard for C++.

I will keep you informed.

Hi Derek,

the project sent included some folders.

cplus_DerekK40CPlusPlusFilter contains the project.

Other folders include MQX project.

According to the info found you're using MK40N512MD100.

Do you have created your own MQX lib ?

I've got lot of problem linked to the MQX lib.

Pascal,

I have created a project that does the following:

Using the exact same project configurations for both of the following examples.

I can include my mqx.h, bsp.h, and fio.h. with no errors.

However if I include <vector> as well I get errors.

BUT if I comment out the first 3 includes, so I'm just including <vector>. I get no errors.

pretty lost at this point =/

Thanks again for your help,

Derek

Derek,

Following your last info I've:

- created a new project using project wizard for MQX 4.0 K40d100M board,

- added the path ${MCUToolsBaseDir}\ARM_EABI_Support\ewl\EWL_C++\include,

- added C++ code and selected the ARM compiler ¦ Language option Force C++ Compilation,

- included the mqx.h, bsp.h and fio.h.

At this side the project can be built without problem.

If I add the vector.h, I got 45 errors.

If I comment the mqx.h, bsp.h and fio.h, I still get the errors.

Attached you will find my project example.
