RE: [lwip-users] LwIP and IAR Workbench

[FreeRTOS.org Info]

Everywhere there is a macro that aligns a struct you have to add in:

#pragma data_alignment=4

Everywhere there is a macro that packs a struct you have to add in:

#pragma pack(1)

Because they use a # you cannot simply define the macro PACK_STRUCT_STRUCT
to do this for you.

Richard.
