CMSIS error "cannot find -llibarm_cortexM7lfdp_math.a"

[carloV]

When I build  my project in "Debug" mode all works fine, if I build the project in "Release" mode an error appears:

 

C:/ST/STM32CubeIDE_2.0.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.13.3.rel1.win32_1.0.100.202509120712/tools/bin/../lib/gcc/arm-none-eabi/13.3.1/../../../../arm-none-eabi/bin/ld.exe: cannot find -llibarm_cortexM7lfdp_math.a: No such file or directory

 

GCC linker

Libraries (-l):                     libarm_cortexM7lfdp_math.a

Library search path (-L):   "${workspace_loc:/${ProjName}/Drivers/CMSIS/Lib/GCC}"   

 

Any help ?

Thank you

"Debug" and "Release" are just different sets of configuration options.

So this means that something's missing in your "Release" configuration; specifically, something which allows it to find that libarm_cortexM7lfdp_math.a library.

So carefully compare & contrast the linker settings for the two configurations.

Is that from the "Debug" or "Release" configuration?

[carloV]

Thank you for your reply,

I set the configuration as "Release", then I insert the library name and the library path into the MCU GCC Linker -> Library

So, again, carefully compare & contrast the settings for the two configurations ("Debug" and "Release").

[carloV]

Ok,

they seem the same...what concerns the linker (GCC linker), there are no differences...do you think that I have to check other part of the setting ?

The message is from the Linker, so it should be in the Linker settings somewhere.

You could try saving the build output from the two configurations, and compare them ...
