[SOLVED] error in adding cpp library to c project in keil

dizgah · Dec 27, 2014

hi every one
im trying to develop a c project in keil ,know i need to add a cpp library file to project & it shows error,i think it is because project uses c compiler & it cant compile cpp libraries,but i dosent have any suggestion to what i must do !
keils error :
error: #20: identifier "class" is undefined
library consist of a lib_XX.h file (for example ) & lib_XX.cpp file
& like any other libraries i include .h file in main.c (my main program file )
#include "lib_XX.h"
-----
libraries dosent have any problem & i used them in keil cpp project before.
is there any suggestion ?

Yes, classes don't exist in C. You should be able to compile the whole project using a C++ compiler instead.

actually im trying to convert my last project to cpp but there is a problem too:
im using https://en.radzio.dxp.pl/ks0108/ library to initial ks0108 GLCD with stm32f103 , every thing is ok except GLCD_Bitmap function

Code:

void GLCD_Bitmap( const unsigned char * bmp, unsigned char x, unsigned char y, unsigned char dx, unsigned char dy)
{
unsigned char i, j;
for(j = 0; j < dy / 8; j++)
  {
  GLCD_GoTo(x,y + j);
  for(i = 0; i < dx; i++) 
    GLCD_WriteData(GLCD_ReadByteFromROMMemory(bmp++));
  }
}

it draws a stored image,GLCD_WriteData function dosent have any problem because other functions used it correctly.
this function declared on ks0108.c file
when there is not declaration of this function on ks0108.h (
void GLCD_Bitmap( const unsigned char * bmp, unsigned char x, unsigned char y, unsigned char dx, unsigned char dy);
) compiler show this warning but program run correct .
warning: #223-D: function "GLCD_Bitmap" declared implicitly
but when i add that declaration to ks0108.h it show error & dosent compile:
error: #167: argument of type "const unsigned char (*)[1024]" is incompatible with parameter of type "const unsigned char *"
im completely mixed up,
i attached completed project if any one help me or give me a other example of ks0108 with stm32
