Compiler: C99 complex in C++ mode is not supported

Tool/software: TI C/C++ Compiler

Hi,

I'm trying to compile my source code(s) that has a mix of C/C++ files and uses float complex types for processing. I'm trying to compile for c66x platform and I encounter issues with support for complex float types in the c6000 compliler. I set the flags to build for c++03 and c99 standard but get the error "C99 complex in C++ mode is not supported". I came across a macro that disables this explicitly in the 'complex.h' header file. Infact, the first few lines states :

#ifdef __cplusplus
# error "C99 complex in C++ mode is not supported."
#endif

Is there a workaround to this problem ?

Thanks.

The implementation of complex numbers is very different in C++ as in C99; they are not compatible. If you must use complex numbers in C++, you must include <complex> and use that system. If you must use C99 complex, move that to a different file and compile it as a C file.

Thank you for the quick reply, Guru. So there is no way to build them in a single project ? Even if the C++ code does not use its own native <complex> library ?

You can use them in the same project; they just need to be in different source files. You can mix C and C++ files in a project.
