BlackNight‌ Thanks, I have checked it, it does not have this beginning.

Hi Jeff,

in that case, it is not a library.

BlackNight, Thanks, I have another question, could you give me some help too? I got a library file from NXP, and add it to my project, but when I make the project, it has an error: "E:/Temp/Sources\TDF8534-CC.LIBRARY: file not recognized: File format not recognized." Does it mean that file can`t be used in S32 design studio? Or I need other setting?

Check your archive if it has this at the beginning of the file:

Hi Suomi,

the library name needs to be lib<name>.a, but in the linker you only specify the name (without lib and .a).

See Creating and using Libraries with ARM gcc and Eclipse | MCU on Eclipse 

or How to use Custom Library Names with GNU Linker and Eclipse | MCU on Eclipse 

I hope this helps,

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.
