May 24, 2010 - 10:38pm Guest	Hello all, after numerous attempts I'm still not able to compile a C++ project under Ride7 (I'm using Windows XP). I know that C++ isn't officialy supported by the IDE, but in this post: http://www.stm32circle.com/forum/viewtopic.php?id=433 VincentC gave some indications in order to compile a C++ project under Ride (above all, using libstdc++). Unfortunately the linker gives me these error messages: Code: Building C:\Documents and Settings\....

Hello all,

after numerous attempts I'm still not able to compile a C++ project under Ride7 (I'm using Windows XP). I know that C++ isn't officialy supported by the IDE, but in this post:

VincentC gave some indications in order to compile a C++ project under Ride (above all, using libstdc++).
Unfortunately the linker gives me these error messages:

I suggest you make a trial with a basic project simply defining a class, initializing it and change its value. This should shows that you did everything to make the use of c++ projects possible. The error messages in your post are more related to symbols definition mismatch due to te use of a kind of printf or malloc function. I think adding into your project the sources from C:\Program Files\Raisonance\ride\lib\ARM\std_sbrk might resolve the problem. Regards Matloub

I suggest you make a trial with a basic project simply defining a class, initializing it and change its value. This should shows that you did everything to make the use of c++ projects possible. Hi Matloub, thanks for your answer! Well, I've tried your suggestion to make a very simple cpp project, but the problem seems to be residing in the use of C++. Suppose we have the following simple class, "Prova", which has a field and a constructor: Prova.h class Prova { public: int valore; Prova(int val); }; Prova.cpp #include "Prova.h" Prova::Prova(int val) { this->valore = val; } The main is this: #include "Prova.h" int main() { Prova p1(2); } When compiling the above code, the linker gives me this output: [...] Building C:\Documents and Settings\....

About your other suggestion regarding std_sbrk: Quote: The error messages in your post are more related to symbols definition mismatch due to te use of a kind of printf or malloc function. I think adding into your project the sources from C:\Program Files\Raisonance\ride\lib\ARM\std_sbrk might resolve the problem. Regards Matloub This seemed to help a bit. In fact, if I copy the sources of that directory in the directory of my sources, then I have only this error message: [...] Building C:\Documents and Settings\...

Thanks :)
