HI Alican Çeviker

Please make sure you build the related libs prior to the usbd_lib_hid_keyboard.

I just test build from my side, it can pass build without any issue. see below:

Have a great day,

Hi ZhangJennie,

The libraries were built before attempting to build the usbd_lib_hid_keyboard project.

I have solved the issue by checking lpc_board_nxp_lpcexpresso_1769 and lpc_chip_175x_6x under C/C++ Genereal -> Paths & Symbols -> References Tab.

Good to know. Thanks.
