NetX Duo BSD integration

[robmilne]

Has anyone successfully used the BSD addon for netxduo inside CubeIDE?  I followed the instructions at the top of https://learn.microsoft.com/en-us/azure/rtos/netx/netx-bsd/chapter2 (the #define TX_THREAD_EXTENSION_3 int bsd_errno needed a trailing semi-colon) but the netx timeval and fd_set definitions conflict with the CubeIDE environment (/ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/select.h and /ST/STM32CubeIDE_1.10.1/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.11.3.rel1.win32_1.1.1.202309131626/tools/arm-none-eabi/include/sys/_timeval.h).

My only reason for using BSD is to to implement ModbusTCP with libmodbus .  I would gladly opt for a native netx implementation of ModbusTCP if anyone knows of one.

Hi rob.

Thanks for your reply.

I continued to do the check-up for a few more days.

The problem was in '#define' command.

#define NX_SOC_ERROR                       -1                       /* Failure.                                                             */
#ifndef ERROR
#define ERROR                               NX_SOC_ERROR
#endif

The 'ERROR' constant also exists in the standard library, causing a conflict.

So, I modified this constant as below. And I replaced from ERROR to BSD_ERROR in nxd_bsd.c file.

#define NX_SOC_ERROR                       	-1                       /* Failure.                                                             */
#ifndef BSD_ERROR
#define BSD_ERROR                           NX_SOC_ERROR
#endif

Now, error is gone.

I will try to do TCP/UDP Test code with nxd_bsd.

Best regards,
