While building mariadb in Amazon linux 2 from a code repo (its not sudo yum install from mariadb external source), I am getting this error as below. Looks like the authentication setup/parameter/code issue. Can someone help?

I have found this link: https://fossies.org/linux/mariadb/plugin/auth_gssapi/README.md But not sure should I do all these or not, as I am pretty new in linux. Also the file(gssapi_server.cc) which error refers to is this : https://fossies.org/linux/mariadb/plugin/auth_gssapi/gssapi_server.cc

Also how to make sure even if the build is failed the Mariadb might work, how to check if the database got installed or not?

src/plugin/auth_gssapi/gssapi_server.cc:34:38: error: ‘krb5_xfree’ was not declared in this scope
 #define krb5_free_unparsed_name(a,b) krb5_xfree(b)

     ^~~~~~~~~~~~~~~~~~~~~~~

Also another error is appearing multiple times in my build log as below:

The database failed to compile so it won't be usable.

The mariadb source checks for krb5_xfree in the header krb5.h at configure time (plugin/auth_gssapi/CMakeLists.txt), so this is odd that is not there at compile time.

Most likely you won't need the gssapi. Its an optional authentication extension. Use the cmake configure option -DPLUGIN_AUTH_GSSAPI=NO to disable the building of this plugin

Yes, the storage engine connect has a few warnings to clean up.
