newlib and standard c++ library

danielomsland — Fri, 08 Jan 2016 13:57:01 GMT

Hi,

I got some problems when changing from ewl to newlib in order to use to Heap.

When including #include <string>, I got: Unresolved inclusion: <string> error.

I am able to do a #include <c++/4.9.2/string>, but I am not able to use std::string nor am I allowed to use the standard namespace: using namespace std;

Is it possible to use any of the standard library functions that needs dynamic memory allocation in S32DS?

Daniel

Hi Daniel,

I have checked your problem and we are working on it. I will try to inform you as soon as possible.

Regards,

Martin

Hi Martin,

Any updates on this? I'm having the same problem. Creating a library with something as simple as what's below fails:

#include <string>
class C {
public:
std::string m_string;
};

Note that the library does compile.

I pocked around and found that by updating the Preprocessor Include Paths, the "Unresolved inclusion: <string> error." goes away.

But, I still get a "Type 'std::string' could not be resolved" error and I wasn't able to get any further... bummer.

Looks like something in the "CDT S32 Built-in Compiler Settings" for C++ is off.

Note his piece does work fine on the Kinetis Design Studio.

Thanks,

René

PS: Do you know where I can find a S32DS vs KDS comparison? Trying to figure out which way to head with KEA family chips...

Was this ever solved? I am having a similar issue with the STL Vector Library. If I change the paths like you said it removes the error on the include, however the constructor is still unrecognized.
