'WindowFunctions' compiling error

[yoc1983]

Might be a noob question but I use the library for fft filters etc.. and all is good now I try to use window functions and I get: undefined reference to `arm_hamming_f32'

on build log I see all directory but not the 'WindowFunctions' any idea how to solve this? seems like it knows about the header but can't find the source file when compiling

@yoc1983 What is the build method you use ? CMSIS build tools ? cmake ? Do you build from the repo or from the CMSIS Pack ?

@christophe0606 Hi,

I call the functions from a C++ code I write in STM32CubeIDE as far as I understand it is using CMake in the background without sharing lot of info or allowing to configure when I press the build button in the IDE I can see in the log it uses all directory except the 'WindowFunctions' I can also see the Cmake files in the directory

I add the CMSIS_DSP through the package manager in the CubeMX I added version 1.15.0 so I guess it is a pack (but I can also see all files and directories like opensource and not a closed library)

also I can see the directory noted in the Makefile :

Sources

and also in CMakeLists.txt :

@yoc1983 I've just looked at the pack description and Windows are not included in version 1.15.0

I see the Windows folder in the pack, but the files are not listed in the pack description file so they won't be built.

Two possible solutions: 1 - You don't use the CMSIS-DSP pack and build from the github version 2 - You use the pack and you copy the Windows folder from the github into your project ..

I understand, I can see on documentation that it is in the list but OK.

since the installing of the pack wasn't easy, had error and now it is working well I won't touch it. I will go with option 2 thanks,
