Should I set gcc in CubdIDE ?

STMCubeIDE comes with all tools needed to build a STM32 project.

Check Project > Properties > C/C++ Build. It should look like:

and Project > Properties > C/C++ Build > Environment contains the path to all tools neded:

The paths are, among others:

C:\ST\STM32CubeIDE_1.1.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.win32_1.0.0.201904181610\tools\bin;

C:\ST\STM32CubeIDE_1.1.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.make.win32_1.1.0.201910081157\tools\bin;

Your settings may vary depending on your version and install options, but they should point to the existing tools installed by STMCubeIDE.

Try Internal builder.

If your computer is managed by IT at work, ask them to stop tampering with your applications.

My fold is empty.

Do not create c/c++ project try to create a new stm32 project. As far as i know if you are using STMCUBE IDE you don't need Cube mx separately.

make a new project from the ide. Most things are configured automatically.

I used CubeMX first, then I imported the MX project into IDE, I wanted to build a project in the imported project from MX.

Check that in you have set Toolchain/IDE to "STM32CubeIDE" in STM32CubeMX Project Manager before generating code.

While, now the project met 5 errors:

"make -j8 all" terminated with exit code 2. Build might be incomplete.

10:16:26 Build Failed. 5 errors, 7 warnings. (took 4s.110ms)

after I added 2 lines here:

   /* USER CODE BEGIN 3 */

    HAL_GPIO_TogglePin (GPIOB, GPIO_PIN_11);

    HAL_Delay (100);  /* Insert delay 100 ms *

 }

 /* USER CODE END 3 */

Those errors happened when I click the left button, when I click the right button, no errors and warnings.

and, when I commented these 2 lines:

    HAL_GPIO_TogglePin (GPIOB, GPIO_PIN_11);

    HAL_Delay (100);  /* Insert delay 100 ms *

everything was OK.

Thanks, I found the reason:

There was lack of "/" at the end of the second line.

Now alas ist OK.

The new question is: could I upload the program inside IDE, or I must use CubeProg ?
