Extending example projects in the IDE

I loathe the eclipsoids so I don't know for this one, but usually there are configuration files for the projects, which are xml thus readable and contain the list of sources from which then eclipse works out. I used to hack out these from the atollic version of the cube examples.

Also, eclipsoids used to have a way to generate a normal makefile, and then you can proceed in the usual adult way.

The examples in SBSFU for SW4STM IDE actively use "linked files", which are the Eclipse way to have portable symbolic links.

(Even though Windows has symbolic links, they are still pain to use...)

"Linked files" is a common feature of Eclipse so it is present in Atollic and CubeIDE as well. It is very powerful but takes some time to get comfortable with.

It's worth to invest effort in learning Eclipse. Agree, it is not pretty, but lot of companies offer Eclipse based IDEs - ARM themselves, TI, Silicon Labs to name some.

Like with riding a bicycle, learn it once and that's it.

Back to the SBSFU examples - the linked files in these are relative to the project directory so all this works because the examples are located in the same source tree with the Cube library. If you move an example outside, this obviously breaks the links.

Linked resources are specified in the .project file; to fix them you can edit .project manually (of course, with caution))

Fix the paths in <link> elements, for example, as below:

<link><name>Drivers/STM32H7xx_HAL_Driver/stm32h7xx_hal_rtc.c</name>
<type>1</type>
<location>PARENT-7-PROJECT_LOC/Drivers/STM32H7xx_HAL_Driver/Src/stm32h7xx_hal_rtc.c</location>
</link>

<!-- change this to: -->
<link><name>Drivers/STM32H7xx_HAL_Driver/stm32h7xx_hal_rtc.c</name>
<type>1</type> <location>file:/your/CubeRepositoryPath/STM32Cube_FW_H7_V1.5.0/Drivers/STM32H7xx_HAL_Driver/Src/stm32h7xx_hal_rtc.c</location>
</link>

Note that "Drivers/STM32H7xx_HAL_Driver" is a "virtual" directory which maps to the matching directory in the Cube library installation.

Eclipse will create these vitual directories under the project bulid root. But they will be empty because the files are somewhere else. TL;DR.

PARENT-7-PROJECT_LOC means 7 levels up from PROJECT_LOC, which is a predefined Eclipse variable that contains the project path. Always use forward slashes / - even on Windows. Eclpise will convert the slashes in the paths properly.

There is a better way to manage these paths, using macros - this is closer to how you would do this in a makefile.

Thanks for all the answers.
