Standard Template Library / C++

Postby steamboy » Sat Jul 24, 2010 3:30 pm

Hello,

Is it possible to use the STL / new operator in my C++ code ?

I have a lot of errors during the compilation process.

Thanks for your help,
Best regards,
Christophe.

Can you give examples of the errors you are getting? All of the C++ standard library is available, but some parts may not fit in the RAM available on the XCore. Some parts of the standard library need exceptions turned on. Exception handling support is turned off by default in the tools to reduce code size. If you see errors like:
error: exception handling disabled, use -fexceptions to enable
Recompile your program with -fexceptions.

Hi,

A stupid question - you were working on a .cpp file not a .c file and bringing in the correct header files?

From the Tools User Guide - page 141
The four possible stages of compilation are preprocessing, compilation proper,
assembly and linking/mapping. The first three stages are applied to an individual
source file, producing an object file. Linking and mapping combine the object files
and an XN file into a single executable XE file, which contains the code and data
segments for each core.
The suffix of a source file determines how it is handled by default.

Extension Type of File
.xc XC source code
.c C source code
.cpp C++ source code
