ERROR: Previous identifier must be a pointer

[Richi-d]

With my old version 3.1xx my program ist compiling and running - with the new 4.xxx not. I read something about pointers...here is a part of my code, can anybody tell me whats wrong?
The error is the one in the headline...


char DATENZEILE[16];


void main()
{
strcpy (DATENZEILE, "Funktionstest ");

for (m = 0; m < 16; ++m)
{
delay_ms(1);
if (y_POS == 1)
{
output_d( 0x80 + m ); //Erste Zeile
output_low(R_S);
output_low(R_W);
output_high(ENABLE);
delay_us(10);
output_low(ENABLE);
}
if (y_POS == 2)
{
output_d( 0xC0 + m ); //Zweite Zeile
output_low(R_S);
output_low(R_W);
output_high(ENABLE);
delay_us(10);
output_low(ENABLE);
}

delay_ms(1);
output_d(DATENZEILE[m]);
output_high(R_S);
output_low(R_W);
output_high(ENABLE);
delay_us(10);
output_low(ENABLE);
}
}
}

Hello,

Here is the sources formatted well with the tag “code”?

Hi,
What I posted is not the complete code- it´s clear that I have to declare the variables and so on...
The error occours in the

[PCM programmer]

[Richi-d]

The version now is PCH 4.018

[Richi-d]

Now I updated the compiler to the newest version- no change !! Has no one an answer?? Why does the code work with the old compiler 3.018?

[ckielstra]

Try to be exact!
For example always mention the version number, a reference to 'the newest version' is not something we can check as there are new releases almost every week.
Another example is that you said it is working in v3.1xx and now you mention the old working version is v3.018. This doesn't match, so again we can't check. Which was the working version?

You haven't posted a small and complete program that we can copy paste into our compiler. This leaves us to guessing. Inservi has been kind enough to extended your given code so it can be compiled and he didn't get the error. Have you tried compiling Inservi's code? Does that compile for you as well? Have you studied the differences in Inservi's code and your program?

Please remember that we are just users like you are. We are here to help each other but we are not going to do your work for you. You will get much better and quicker responses when you make it easy for us to reproduce your problem.

Meanwhile I found the error-

This is wrong:

void Write_Display_Data_ZEILE ( y_POS, DATENZEILE )


This is right:

void Write_Display_Data_ZEILE ( y_POS )

It seams that the new version doesn`t allow to define the array"DATENZEILE" as global and to give it in the function additional.

But now I have a new problem: When the programm runs over this line:

I only count 16 characters, I tested it with:

I'm also getting this error "Previous identifier must be a pointer"

I'm running PCM 4.032

I have numerous arrays, but for some reason one is singled out for this error.

The variable is declared with global scope:

Somehow I managed to make the previous post without being logged in.

This reply is so I can get reply notice emails.

Thanks Again for any insight!!!

I uncovered the source of these difficulties.

There was a preprocessor symbol defined that only differed from the variable name in case: i.e.
