I am porting some code to 43xxx_Wi-Fi project.

In the code being ported following lines are present.

typedef float float32_t;

typedef double float64_t;

typedef bool bool_t;

typedef char char_t;

typedef unsigned char uint8_t;

typedef signed char int8_t;

typedef unsigned int uint32_t;

typedef unsigned short uint16_t;

typedef signed short int16_t;

typedef signed int int32_t;

typedef unsigned long long  uint64_t;

typedef signed long long  int64_t;

In  one of the files (tools/ARM_GNU/include/stdint.h)  below lines are present.

typedef signed long int32_t;

typedef unsigned long uint32_t;

compiler is throwing error because of conflicting typdefs of int32_t and uint32_t.

I think there would be some option to config stdint.h file so that all data types matches with code being ported.

Any help in this regard is commendable

hello:

   if your code is not very huge , I think changing  the typedef in your code side is better for the compile:

typedef unsigned int uint32_t;

typedef unsigned short uint16_t;

typedef signed short int16_t;

typedef signed int int32_t;

and better to add a global define to control the modification.

I am marking this question as assumed answered as this is duplicate of my question.

I don't know why it is showing twice even though i unmarked as question.

By the way below is my reply :

That is what i have done now.

But because of this change i am getting some other compilation issues in ported lib.

For example:

there is a function declaration in third party stack as below

int fn_name()

and function definition is in some other file as below

int32_t fn_name()

{

//function body

}

as per stdint.h int32_t  is signed long

means function definition looks as below

signed long fn_name()

{

//function body

}

function declaration and function definition prototype is not matching leading to compilation error.

I am not supposed to change third party stack (so that i can upgrade blindly to latest available version)

I understand that this type of errors come as third party stack has not followed standard convention for datatypes.

and i am sure that this is not something new.

I didn't got any good answer after googling.

so posted question here with the hope of getting practically implementable solution.

Just a suggestion , I think:

We must comment the typedef from your .h file,  and just keep the necessary part for your code.

then include current stdint.h again into your code .  Because now you are using wiced environment , I think the basic define should use wiced defines also.
