lerning namespaces (cpp) [message #1741719]

hi

im still in the learning process of cpp, todays work is to use namespaces.
the goal: define functions outside of a class, therefore, no object is needed to execute the function.

initial step (tutorial):

main.cpp:

namespace HWLib
{
  void Initialize(void);
}

void HWLib::Initialize(void)
{
  HAL_Init();
}

int main(void)
{
  /* Initialize HWLib */
  HWLib::Initialize();

works without any problem.

step 2: move into a separate source and header file:

main.cpp:

#include "HWLib.hpp"

int main(void)
{
  /* Initialize HWLib */
  HWLib::Initialize();
}

HWLib.hpp

namespace HWLib
{
  void Initialize(void);
}

HWLib.cpp

#include "HWLib.hpp"

void HWLib::Initialize(void)
{
  HAL_Init();
}

starts with: unknown type name 'namespace' and some other errors indicating missing line endings and brackets.

do you see the error?

CLOSED! Solution: Since it is a c/cpp project, somehow the gcc compiler was used for the namespace compilation instead of the g++.
