stm32-cmake common.cmake get_filename_component(STM32_TOOLCHAIN_PATH ${STM32_TOOLCHAIN

Describe the bug If I do not explicity set STM32_TOOLCHAIN_PATH cmake exit with this error:

Not searching for unused variables given on the command line.
[cmake] CMake Error at Modules/stm32_cmake/cmake/stm32/common.cmake:29 (get_filename_component):
[cmake]   get_filename_component called with incorrect number of arguments

Sources to reproduce

I am just using vscode with the compiler in my path and with the following parameters that are passed to cmake:

  "cmake.configureArgs": [
        "-DSTM32_CUBE_F4_PATH=${workspaceFolder}/Src/ST/STM32CubeF4",
        "-DFREERTOS_PATH=${workspaceFolder}/Src/Application/Middlewares/Third_Party/FreeRTOS/"
    ],

the output from the initialization is:

Executing command: /usr/bin/cmake --no-warn-unused-cli -DSTM32_CUBE_F4_PATH=/workspaces/KPIO06CTRL/Src/ST/STM32CubeF4 -DFREERTOS_PATH=/workspaces/KPIO06CTRL/Src/Application/Middlewares/Third_Party/FreeRTOS/ -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=arm-none-eabi-gcc -DCMAKE_TOOLCHAIN_FILE:FILEPATH=/workspaces/KPIO06CTRL/Src/Modules/stm32_cmake/cmake/stm32_gcc.cmake -H/workspaces/KPIO06CTRL/Src -B/workspaces/KPIO06CTRL/build -G Ninja

Expected behavior That cmake configures correctly help explain your problem.

Environment (please complete the following information):

OS: Ubuntu
stm32-cmake: commit 2dc0456
cmake: 3.18
HAL/cube/CMSIS: v1.26.1

Additional context If I remove the line with the get_filename_components the compiler is correctly detected and the compilation goes on.

In my opinion this line should not be there, if I do not set the STM32_TOOLCHAIN_PATH, how could this variable be used in the source file?

Sorry, I hit the comment button before adding other context.

I had a previously used application that was not updated with the latest code in more or less 6 months, I am trying to switch branch from the "new cmake" to the current master.

I am hitting two errors, this is the first. The other one I will add a different issue.

Hi again,

Can we see a snapshot of your CmakeLists.txt too please?

Hi again,

Can we see a snapshot of your CmakeLists.txt too please?

Hi, Moreover, are the examples working or is only your legacy code not working ?

Hello Again,

thank you to you both for your fast reply.

As @atsju pointed out it was correct to test the samples.

At the moment I applied my modification to the blinky-example and it seems to me that I am observing the exact same behavior.

As anticipated, for the development I am using a devcontainer but the same I can see outside the container.

I compiled the F4 example only. In order to have it correctly compiling I had to add the following line

target_compile_definitions(stm32-blinky-f4 PRIVATE VECT_TAB_OFFSET=0x00)

After taking the output I noticed that I did not copied the package.xml file but just the libraries in the correct position, therefore you can see the output Could not read the HAL version from package.xml for STM32F4 I rechecked the output with the file package.xml in the correct position but the result is unchanged.

Hi, VECT_TAB_OFFSET is defined in system_stm32${FAMILY_L}xx.c this is found while using FindCMSIS. It looks like you did found it while configuring cmake (otherwise you would have an error message). We can see that the file is indeed built...

As you can see here : https://github.com/STMicroelectronics/STM32CubeF4/blob/4aba24d78fef03d797a82b258f37dbc84728bbb5/Drivers/CMSIS/Device/ST/STM32F4xx/Source/Templates/system_stm32f4xx.c#L104

It is indeed defined. Did you made any change to this file? Is it properly mounted into your docker container and all?

Nov 20 '21 13:11 Hish15

Hello!

Mmm...

Can't say now. I need to check. Anyway this issue is not related to the VECT_TAB_OFFSET macro.

I can try again with a clean setup.

What I was noticing is that if STM32_TOOLCHAIN_PATH is not defined, the configure process exits with error.

The VECT_TAB_OFFSET could be related to a change to a previous version made for adding it as a Param from my cmakelists.txt

Hi @andyinno Do you have any update on this issue ? Or may we close it ?
