Per the standard, malloc is declared in stdlib.h1 which is already included.

@ahuo-dev Could you share what environment you were trying to solve what problem, then we can look at whether this is the best fix.

@basvodde My project use amazonaws kinesis video stream code. I have a compile error when enable cpputest memory leak check . and I found amazonaws kinesis video stream code use malloc header with malloc.h. see this code line 523 at https://github.com/awslabs/amazon-kinesis-video-streams-pic/blob/master/src/common/include/com/amazonaws/kinesis/video/common/CommonDefs.h

Ok, but the include of #malloc.h in the CommonDef.h shouldn't need to trigger you to include it in the SatndardCLibrary.h, right?

Could you share what the compile error is that you are getting?

Compile error message :
"nclude/CppUTest/MemoryLeakDetectorMallocMacros.h:36:47: error: expected declaration specifiers or ‘...’ before string constant
36 | #define malloc(a) cpputest_malloc_location(a, FILE, LINE)"

and run command "gcc -E " to expand all macro. I see malloc function prototype expand to cpputest_malloc_location, like this :
extern void *

38 "/usr/include/malloc.h"

        cpputest_malloc_location(

38 "/usr/include/malloc.h" 3 4

        size_t __size

38 "/usr/include/malloc.h"

        , "/usr/include/malloc.h", 38)

38 "/usr/include/malloc.h" 3 4

                               __attribute__ ((__nothrow__ , __leaf__)) __attribute__ ((__malloc__))
 __attribute__ ((__alloc_size__ (1))) ;

Normally it should be like this:
extern void *malloc (size_t __size) __THROW attribute_malloc
attribute_alloc_size ((1)) __wur;
