LwIP and compiler 6

Good moorning,

I am trying to use LwIP to do a RAW Socket TCP connection.
I have did it without problems but i used the compiler 5, i want add this development to another proyect that i am doing but in that i use the compiler 6.
When i try to migrate it, appears too many compile errors.

Do you know if there are any limitations?
Someone use LwIP with the compiler 6?

I am working with a ST microcontoller, the STM32F779NI.
The IDE that use is the KEIL MDK.

I hope you can help me.
Thank you very much for you time.

Good Moorning,

I finaly resolved it.

First i found the correct sintaxys for DMA reserve.

 // Ethernet Rx DMA Descriptors
   __attribute__((section(".ARM.__at_0x2007C000")))  \ 
   ETH_DMADescTypeDef  DMARxDscrTab[ETH_RXBUFNB];

 // Ethernet Rx DMA Descriptors
   __attribute__((section(".ARM.__at_0x2007c080")))  \ 
   ETH_DMADescTypeDef  DMATxDscrTab[ETH_TXBUFNB];

 // Ethernet Rx DMA Descriptors
   __attribute__((section(".ARM.__at_0x2007C100")))  \ 
   uint8_t Rx_Buff[ETH_RXBUFNB][ETH_RX_BUF_SIZE];

 // Ethernet Rx DMA Descriptors
   __attribute__((section(".ARM.__at_0x2007D8D0")))  \ 
   uint8_t Tx_Buff[ETH_TXBUFNB][ETH_TX_BUF_SIZE];

Second i changed the memory map in sct file.
I changed the size of IRAM1, for have a space reserved.

RW_IRAM1 ADDRESS SIZE{ ;RW data
        .ANY(+RW +ZI)
}

  }
  RW_IRAM1 0x20020000 0x0005C000  {  ; RW data
   .ANY (+RW +ZI)
  }
  RW_IRAM2 0x20000000 0x00020000  {
   .ANY (+RW +ZI)
  }
}

Thank you very much for you time and help.
