Trouble building TCPIP stack with PCD compiler?
PostPosted: Mon Aug 02, 2021 7:47 am     Reply with quote

Does this build without changes? - I am getting hundreds of errors thrown up by "GenericTypeDefs.h" to do with simple identifiers and declarations.

Example:
Executing: "C:\Program files\Picc\CCSC.exe" +FD "Main.c" #__DEBUG=1 +ICD +DF +LN +T +A +M +Z +Y=9 +EA #__PIC24FJ256GA106__=TRUE
*** Error 28 "C:\Proj\9731\CockitTerminals\9731LCD\9731LCD_DZUS\Software\9789WithHDX1100\tcpip\GenericTypeDefs.h" Line 64(22,28): Expecting an identifier
*** Error 43 "C:\Proj\9731\CockitTerminals\9731LCD\9731LCD_DZUS\Software\9789WithHDX1100\tcpip\GenericTypeDefs.h" Line 64(30,31): Expecting a declaration

from this line:
typedef enum _BOOL { FALSE = 0, TRUE } BOOL; /* Undefined size */

It doesn't seem to like FALSE and TRUE.

I was hoping it would just build, out of the box.
Any input gratefully received.

I was able to get it to compile by #undef'ing TRUE and FALSE as
shown below:
Code:
#include <18F46K22.h>
#fuses NOWDT 
#use delay(internal=4M)   
 
#ifdef FALSE
#undef FALSE
#endif

#ifdef TRUE
#undef TRUE
#endif

typedef enum _BOOL { FALSE = 0, TRUE } BOOL;

//=================================
void main()
{

while(TRUE);
}

Yes, I hit this years ago.
CCS, in the processor file, has TRUE and FALSE #defined as 0 and 1.
This causes issues with the enum 'definition', used in the GenericTypeDefs
file.
As PCM says all you need to do is undefine them, before you load this
file.
Touch wood, that you don't get too many other problems. I remember
there being a few when I tried this....
