(don't know where the above "Normal 0 false false false" came from!!!!!!!!!!!!!)

CCSv4

csl_c6472_03_00_06_03

BIOS 6.21.03.21

XDAIS 6.25.01.08

The problem I’m having is that when we use csl_types.h and xdc\std.h, I get the error:

error: "Int8" has already been declared in the current scope

The conflict arises because csl_types.h includes tistdtypes.h. Both xdc\std.h and tistdtypes.h have an Int8 typedef. Hence the error.

I would like to use csl_types.h because I have functions that return type CSL_Status.

So I’m stuck. Either I change the EDMA functions to not use CSL_Status or purge the code of all std.h references (and thats a scary thought since who knows how many problems that will create).

Any thoughts on how to fix this issue?

I also get a

warning: typedef name has already been declared (with same type)

for Char, Int, Bool, Int16, Int32, Ptr, String, Uint8, Uint16, Uint32, and Uns

Wonderful!

I checked the TISTDTYPES.h and seems like it is the same as xdc/std.h. So can you comment the #include<TISTDTYPES.h> in the csl_types.h file. I am still not sure how you got the error only for int8 as it should be for all the types. We will try to slove it in the next csl release.

Thanks,

Arun.

Thanks!

The reason I think is because the typedefs are

xdc\std.h:

typedef signed char xdc_Int8;

typedef xdc_Int8 Int8;

tistdtypes.h:

typedef char Int8;

The compiler does not like one being char and the other being signed char.

Isn't tistdtypes.h wrong? It should be signed right? Or the compiler knows that char is signed?

So is this going to be fixed? We still see the problem with

CGT 7.04

and

csl_c6472_03_00_06_03

Furthermore, one of my co-workers says that if we use xdc\std.h instead of csl_types.h, the EDMA routines do not work.

Cheers
