Compiling error

Mathieu Lévesque

Hi, I have strucr define in a lib file from TI. Here the message error from Keil uvision 4, I got no error in my include:

Build Project 'PTX' - Target 'PTX'
compiling main.c...
C:\Users\Mathieu\Documents\Stage\Code_base_station\CodeBaseStation\PTX\src\usb_bulk_structs.h(42): error:  #20: identifier "tUSBBuffer" is undefined
  extern const tUSBBuffer g_sTxBuffer;
KB: Unexpected type: 0

KB: Unexpected type: 0
<error type>src\main.c: 0 warnings, 3 errors
".\PTX.axf" - 3 Error(s), 0 Warning(s).

Anyone know how to fix this?

    When is tells you that something is un-defined, the obvious fix is to define it - surely??

    usb_bulk_structs.h(42): error:  #20: identifier "tUSBBuffer" is undefined
  extern const tUSBBuffer g_sTxBuffer;

    As others have noted, it probably means that you've omitted to #include the header containing the definition...
