How to build the alsabat with libfftw3 on IMX8MM(Yocto)

[jimi_lin]

HI

We want to use the alsabat on Yocto, how do I build the alsabat?

And it seems that libfftw3.so is necessary, we also need to know how to build the .so on Yocto.

Is there any document? Or?

Thanks

Hello Jimi Lin,

The BSP does incorporate a fftw package, which on the 5.4.3 release is version 3.3, you can find the version available on your BSP by running:

$ bitbake -s | grep fftw

If this package suits you needs you can add it to your local.conf to install on the baked image

IMAGE_INSTALL_append = “ fftw”

I hope this helps!

HI gusarambula

Thanks for your explanation, I will try it.

And how about the alsabat? Is there any config or option to enable the build of alsabat?

Thanks

Hello Jimi Lin,

There are some alsa packages available on the Yocto BSP but I haven’t seen an alsabat package. It could be included as part of the alsa-utils package so it would be worth looking.

I hope this helps!
