Yocto Kirkstone gnutls error: Libhogweed not found

[ahmedmd]

Hello Guys,

I'm trying to build an image using Yocto Kirkstone provided by NXP. I keep getting a missing library file missing error. The package is gnutls-3.7.4. It gives me error like libhogweed not found.

|   *** Libhogweed (nettle's companion library) 3.6 was not found. Note that you must compile nettle with gmp support.

I have tried including the below lines in the nettle bb file:- 

PACKAGES += "libnettle libhogweed"
FILES:libnettle = "${libdir}/libnettle.so.*"
FILES:libhogweed = "${libdir}/libhogweed.so.*"
EXTRA_OECONF += "--enable-shared"

This has not helped me. Any ideas on how to solve this error of mine ?

I was able to solve this error. Posting the answer here in case someone else also gets this error and is looking for a solution.

This was caused due to incompatible versions. nettle_3.7.3 requires minimum gmp 6.1 version. But i was using gmp_4.2.1. 
After downloading a newer version layer of gmp and including it, the error went away. I used gmp_6.2.1 version to solve this error.

If you are encountering this error, my suggestion would be to first check the compatibility of the layers and software versions.

I'm trying to build the gnutls layer directly. I have given "bitbake gnutls"

I am doubting it might be a version mismatch. Does gmp_4.2.1 work with gnutls_4.7.3 ?

what's your build steps? let me double check it
