in order to include FreeRTOS+TCP in my project, I followed the guide “Porting FreeRTOS+TCP to a Different Microcontroller” as no complete examples were available for my platform.
I’m using FreeRTOS 10.2.1.
The guide suggest to use eConsiderFrameForProcessing(…) before processing the frame. Actually, I verified that both the function eConsiderFrameForProcessing and the enum eProcessBuffer are defined in FreeRTOS_IP_Private.h header file.
In order to get access to those symbols I directly included FreeRTOS_IP_Private.h in my module.
Everything was fine until I decided to use Message Buffers in the same module. When including also message_buffer.h, in fact, I get the following error:
…\FreeRTOS_TCP_Source\include\FreeRTOS_Stream_Buffer.h:178:30: error: conflicting types for ‘xStreamBufferIsFull’
static portINLINE BaseType_t xStreamBufferIsFull( const StreamBuffer_t *pxBuffer );
In file included from …\FreeRTOS_Source\include/message_buffer.h:66:0,
…\FreeRTOS_Source\include/stream_buffer.h:629:12: note: previous declaration of ‘xStreamBufferIsFull’ was here
BaseType_t xStreamBufferIsFull( StreamBufferHandle_t xStreamBuffer ) PRIVILEGED_FUNCTION;
In fact, it looks that some symbols defined in message_buffer.h are also re-defined in FreeRTOS_Stream_Buffer.h, included by FreeRTOS_IP_Private.h.
Not sure whether the mistake is in including FreeRTOS_IP_Private.h (maybe there is a more correct approach to have access to eConsiderFrameForProcessing and eProcessBuffer symbols) or in something else.
Thanks in advance for your support.
