Getting the below compilation issue.

Looks like a compiler bug. Try adding -Wno-error=attributes.

When I went ahead with the above option, it fixed that error (only after editing the make file and didn't work with command line option) but I encountered below errors which seems to be mis-match of number of arguments and another error with -Werror=implicit-function-declaration. Though I don't see Werror in any make files, don't undertstand where it is referring to.

Error1 Error2

There is a bug in GCC8, using GCC7。 https://patchwork.ozlabs.org/project/uboot/patch/20180507201827.29669-1-xypron.glpk@gmx.de/
