how to link CMSIS DSP to KDS project

[ronyip]

I have been trying to link the CMSIS DSP lib to my MK24F project in KDS version 3.0. I am using KSDK version 1.3.0.

I was so glad to have found the instruction provided in this link Adding CMSIS-DSP Library to a KSDK 2.x project in Kinetis Design Studio. It looked like it should have worked. However, I still have the same error after implemented the steps provided in the pdf file.

c:/freescale/kds_v3/toolchain/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld.exe: cannot find -llibarm_cortexM4lf_math.a

collect2.exe: error: ld returned 1 exit status

makefile:116: recipe for target 'mk24f.elf' failed

make: *** [mk24f.elf] Error 1

I checked the make sure I was using the '/' instead of the '\' and pasted the path in the file explorer to verify that it was correct. Any idea why the ld.exe was not able to find the lib file?

Thank you,

Ron

Hi Ron,

Is you linker pointing to the correct folder where the library is located?

The CMSIS library is in the KSDK path and not the KDS path I think:

C:\Freescale\KSDK_1.3.0\platform\CMSIS\Lib\GCC

Here the lib settings in project properties.

The Library search path is "C:\Freescale\KSDK_1.3.0\platform\CMSIS-SP-00300-r4p5-00rel0\CMSIS\Lib\GCC"

The library name is libarm_cortexM4lf_math.

Hi Ron,

Try using the name "libarm_cortexM4lf_math".

Thanks, Dave,

I tried putting "" around the lib name with the same error.

Building target: mk24f.elf

arm-none-eabi-g++ -mcpu=cortex-m4 -mthumb .... -l"libarm_cortexM4lf_math"

Hi Ron,

I goofed.  I meant following:

Try using the name "arm_cortexM4lf_math"...without "" and without the prefix "lib".
