make modules_prepare results in an error on 4.15.0-60-generic

Asked by Suresh Sandur

Hi,

I have been trying to build vmlinux on Ubuntu 16.04 and also on Ubuntu 18.04 for kernel version 4.15.0-60-generic, with the relevant headers and latest sources.

However, I am getting this error:

I have not done any other changes. Just installed the kernel-image, installed the headers and installed the kernel sources from UBuntu repository.

Can you please look into this.

Adding further info:

the new addition to scripts/genksyms/keyword.c,

        { "__int128", BUILTIN_INT_KEYW },
        { "__int128_t", BUILTIN_INT_KEYW },
        { "__uint128_t", BUILTIN_INT_KEYW },

also to scripts/genksyms/parse.y seems to be the issue.

When I comment out the additions to keyword.c the "make modules_prepare" completes successfully.

The other way to resolve this is to add the token BUILTIN_INT_KEYW to the enum yytokentype in scripts/genksyms/parse.tab.[ch]_shipped

The following inclusion seems to be the issue.

linux-hwe (4.15.0-59.66~16.04.1) xenial;

    - genksyms: Teach parser about 128-bit built-in types

This happens when CONFIG_MODVERSIONS is set to yes.

make REGENERATE_PARSERS=1 before make modules_prepare resolves the issue
