Compiler / Linker Broken in CubeIDE

matt-crc · ‎2025-03-27

The CubeIDE linker doesn't seem to work properly... Any help would be greatly appreciated. ST Employee help?????

1- In the UserStartup.c, I call lv_init();

2- After compiling, it says it cannot find lv_init()

3- I see that the file lv_init.c file got compiled (lv_init() is defined in that file) - the object file was created lv_init.o

4- It seems the linker cannot find that file....

Is there a limitation on the number of files the linker can handle?

The linker in the toolchain of CubeIDE has no limitations. The file lv_init.c indeed seems to be compiled. Try to double check why lv_init.o is not linked or the required functions in it are not found. Bug in the linker is unlikely. Bugs of this kind usually occur between the chair and keyboard ))

Hi @Pavel A.

I'd be really happy if the bug is between the chair and keyboard, but things seem to be pointing to the compiler. Also, in the pre-compiler, there seems to be a problem with the includes.

In one file (early on in the compile), it has no problem finding the "#include "lvgl.h" file. as the 6 min compilation continues, files compiled later with the same "#include lvgl.h" generates and error: "Cannot find include file"

If I change the "#include "lvgl.h" to the real path, and not using the include search path, then the file compiles... To me this looks and sounds like a compiler limitation....

Also, there seems to be a limitation to the number of SRC directories defined in CubeIDE (max 10). Most were autogenerated by CubeMX. I know this is a large compile and we are definitely pushing the limits of the IDE.

What is the CubeIDE version and STM32? Is any antivirus (or worse) installed? Are you by chance low on disk space?

matt-crc · ‎2025-03-27

Hi @Pavel A.

The machine that I'm using is a Dell Precision 3660 with 12th gen processor, and 64gb mem. Over 1.2TB free on disk

STM32CubeIDE is version 1.18.0, Build 24413_20250227_1633

No antivirus installed,

Is it?

You haven't shown that

Can you copy the full contents of the Console tab from a clean build into a text file and include it here?

If you feel a post has answered your question, please click "Accept as Solution".

matt-crc · ‎2025-03-28

Hi @TDK

Funny that you suggested that... I've been trying to do that for days.... Unfortunately I can't figure out how to capture the entire console. It scrolls past the console buffer size, so I can only get the bottom 1/3 of the project. Is there a setting that increases the buffer size? I see there were some warnings when compiling but I haven't been able to scroll back to see them.

BTW, I finally reduced the size of LVGL component by unconfiguring a lot of options and finally got a working executable. I was going to run it this afternoon to see how it runs on the hardware.

matt-crc · ‎2025-03-28

This is all that the console can capture
