build error in GenericTypeDefs.h

[resodad]

Hi Lubin,
Is this a bug?
the attached model generates this error when generating code:

Code: Select all

..\../GenericTypeDefs.h:64:22: error: expected identifier before '(' token 

and the offending line of GenericTypeDefs.h is:

Code: Select all

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

which looks OK.

I am using C32 V2.00 compiler

Hi John,

The problem appears for 24fj chips : see forum post here
It has been corrected for 24Fj chips : the dsPIC blockset now generate its own GenericTypeDefs.h file.
I will do the same correction for 32f Chips.

The workaround is just to modify the file GenericTypeDefs.h like :

Code: Select all

 // typedef enum _BOOL { FALSE = 0, TRUE } BOOL;    /* Undefined size */
 typedef enum _BIT { CLEAR = 0, SET } BIT;

It should fix the problem.

Thanks Lubin, I already tried that; now the error is "chased" to a new line of a different header file that depends on BOOL:

Code: Select all

In file included from ..\../CustomSD.c:8:0: 
..\../FSIO.h:272:5: error: expected specifier-qualifier-list before 'BOOL' 
gmake: *** [CustomSD.o] Error 1 
### Real-Time Workshop build procedure for model: 'SD_Datalogger' aborted due to an error.

I did not use code where the BOOL type were required.
Thus I have no solution for that. There might be more usefull information on Microchip forum for this.

Anyway, I would be glad to get the final word. It is weird that this BOOL enumeration does not work.

Lubin, Microchip tech support looked into it but could not find the problem. John

Lubin, maybe this is a clue? I tried replacing

Code: Select all

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

with

Code: Select all

typedef enum _BOOL { NO_FALSE = 0, YES_TRUE } BOOL;

and the result was:

Code: Select all

sources/SD_Datalogger.c: In function 'SD_Datalogger_initialize':
sources/SD_Datalogger.c:195:19: error: 'T1_INT_PRIOR_0' undeclared (first use in this function)

etc. I t looks like it got past the GenericTypeDefs and FSIO headers. Was it getting stuck on key words FALSE and TRUE?
Now it's not finding the timer configuration variables...

Lubin,
Are my files being executed out of order?

see this post on a microchip forum where there was a duplicate #define FALSE:

Hi John,

The best might be to modify the generated code within MPLAB X until it's working. Thus trying the microchip forum's solution with MPLAB and the generated code. Then finding a trick to make it works from simulink straight.
It's difficult to help you more on this.
However, could you post the c source code for the SD : CustomSD.c etc... I guess this is microchip's template ?

Lubin

[resodad]

Lubin, No, there is no solution on microchip forum for this. The post I referred to had duplicate definitions, and that is not my case.
CustomSD.c is written by my colleague here to manage file init/open/close/write commands:

Code: Select all

#include <p32xxxx.h>
#include <stdlib.h>
#include <string.h>
#include <stdio.h>
#include "FSconfig.h"
#include "HardwareProfile.h"
#include "GenericTypeDefs.h"
#include "FSIO.h"

#define NumRetries 10

FSFILE * filePtr;


unsigned char FS_init_loop(void){
    unsigned char i;
    for (i=0; i < NumRetries; i++){
    if(FSfinit()==0)  return 1;
    return 0;    
    }
}

unsigned char FSopen(char *u1){
    filePtr = FSfopen( u1,FS_WRITE);
    if (filePtr != NULL) {
        return 1;
    }
    else return 0;  
}

void FSclose(void){
    FSfclose(filePtr);
}

unsigned char FSprint(unsigned int u1){
    char y1;
    y1 = FSfprintf(filePtr, "AN0= %u%c%c", u1, 0x0D, 0x0A);
    if (y1 > 0){
        return 1;
    }
    else return 0;
}

Lubin and all:
I have found a clue about this problem. please note:
1. attachment SD_Datalogger2.mdl contains NO CUSTOM CODE.
There is no build error when the MATLAB working folder is set correctly to the same location when the .mdl file is saved.
HOWEVER, the same file produces the GenericTypeDefs error if the MATLAB working folder is set one folder above.

2. attachment SD_Datalogger3.mdl does contain CUSTOM CODE. That is the only difference. Custom code is incorporated via >Simulation>Configuration Parameters>Code Generation>Custom Code> Include Directories and ...>Source Files.
This file produces the GenericTypeDefs error even if the MATLAB working folder is set correctly.
Please see if you can duplicate this.

I suspect the paths of the included files are the source of the trouble.

Hi Lubin and all,
I am still very stuck on this problem. Please confirm that you can duplicate the problem (#2 above).
the error is:
"
...GenericTypeDefs.h:65:22: error: expected identifier before '(' token
"
But there is nothing wrong with the code in this file. It is Microchip sourced and proven.

Do I have all the source files and header files in the right locations?
Am I missing a file?
Do I have a duplicate definition?

I have tried different arrangements of included source code and include directories.

I have tried this using several versions of Microchip compilers and MPLAB and different versions of Matlab.
Currently I am using
MATLAB R2011a
MPLAB IDE v8.76
C32 compiler v2.01
and
Embedded Coder for dsPIC V3.7(08-Oct-2011)

I am attaching everything.

Can you please help?
John

Microchip Tech Support says:
"
I think the issue is that you are including the GenericTypeDefs after rtwtypes.h, and there the FALSE and TRUE are defined.\
So FALSE is replaced with (0U), so the parsing fails.
You should try to include the timer.h before the rest of your own files.
"

I tried following this suggestion, but I'm not sure I'm doing it right. All my attempts resulted in errors.

I moved the c file names to:
Simulation > Configuration Parameters > Simulation Target > Custom Code > Source File (under Include Custom c code in generated:)
and moved the include directories to this page as well, and the simple model (turn on LED) compiled without error, but a more complicated model (data log to SD card) had the same GenericTypeDefs.h error.

Hello John,

I could not spend too much time on this specific problem.
Interfacing with other driver might be difficult.
However, here is my finding:

You copied two files :
GenericTypeDefs.h
timer.h
in the Include folder that you include that are already included within the compiling process. Including theses files creates an error. (Are theses the correct ones ? )

I still get an error, but I think compiling process goes slightly better :

Hello,

I don't know if this can help but I had a quick view on the code and I haven't been able to find the FSfinit function in the Microchip application note AN1045 (http://ww1.microchip.com/downloads/en/A ... 01045b.pdf) but I guess this function initialize the card so maybe you should try to replace in teh CustomSD c file at line 18 the FSfinit by FSInit. In my case the code is compiling in both Simulink and in MPlab.

Regards.

Philippe
