STemWin issues during linkag: undefined reference to `OS_TimeMS' ?

I tried to compile the 'Hello World' example provided in stm32cube F7 package, with no success.

I copied all files from STM32Cube_FW_F7_V1.11.0/Projects/STM32746G-Discovery/Applications/STemWin/STemWin_HelloWorld/Core and STemWin/ folders

and tried to compile, with correct link flags.

I get errors:

pio_builds/disco_f746ng/src/stm32f7xx_it.o: In function `SysTick_Handler':

stm32f7xx_it.c:(.text.SysTick_Handler+0x10): undefined reference to `OS_TimeMS'/.../Middlewares/ST/STemWin/Lib/libSTemWin540_CM7_GCC.a(GUI_Core.o): In function `GUI_Init':GUI_Core.c:(.text.GUI_Init+0xbc): undefined reference to `GUI_X_Init'

I added the 'lib-' prefix to the library and included following flags to gcc:

-I/home/jure/Projects/ARMdev_stuff/STM32Cube_FW_F7_V1.11.0/Middlewares/ST/STemWin/inc

-L/home/jure/Projects/ARMdev_stuff/STM32Cube_FW_F7_V1.11.0/Middlewares/ST/STemWin/Lib

-lSTemWin540_CM7_GCC

-lSTemWin540_CM7_GCC_ARGB

-lSTemWin540_CM7_GCC_ot

-lSTemWin540_CM7_GCC_ot_ARGB

mfloat-abi

=hard

mfpu

=fpv5-sp-d16

I am using STM32F7 discovery board, stm32cube framework (HAL) and no RTOS or anything.I didn't change any code in the Hello World example, which is written exactly for this platform. What should I do?

Hello

vidmarjur

,

Have you copiedthe

fileGUI_X.c?

You should copy the

GUI_X.c file

$Library_path\STM32Cube_FW_F7_V1.0\Middlewares\ST\STemWin\OS\GUI_X.c

to folder

‘\Src’

in root of your project.

With Regards,

Imen

Yes, this resolves the issue!

How come that this file is not already in src/ folder of the given Hello World example? o.0Documentation (Getting started with STemWin) didn't mention that it's necessary to include GUI_X.c explicitly.Well, however it compiles now.Thank you for your help and time !
