How to create and use static library in S32DS

Hi Nxp!

  Recently, I encountered a problem when using S32DS_v2.2 to compile my project with other static library. I refer to guidance of HOWTO:Add a static library file into S32DS GCC projectileshttps://community.nxp.com/t5/S32-Design-Studio-Knowledge-Base/HOWTO-Add-a-static-library-file-into-S...; I think I have no problem setting it up, but the following error occurs during compilation. Can you help find the cause of the problem? thank you very much

Description Resource Path Location Type
Ld error: can_pal_s32k142.elf uses VFP register arguments, E:/DeskTop/1234/S32DS/testFunction1/Debug\libtestFunction1.a(mylibrary.o) does not C/C++ Problem

Hi, 

your issue is probably caused by different compilator settings for library and executable. You can find more details for example here - https://stackoverflow.com/questions/9753749/arm-compilation-error-vfp-registers-used-by-executable-n... 

The float point settings you can find in project properties:

Hello, I follow the normal methods of generating and adding static libraries. When I added static libraries, the following error appeared. May I ask what caused it?

Building target: BMS_2_2.elf
Invoking: Standard S32DS C Linker
arm-none-eabi-gcc -o "BMS_2_2.elf" "@BMS_2_2.args"
arm-none-eabi-gcc.exe: error: : No such file or directory
make: *** [makefile:86: BMS_2_2.elf] Error 1
"make -j16 all" terminated with exit code 2. Build might be incomplete.
