Hello @Ashkian,

**1 -running the following command results the following message, what does it mean, is it a issue?

Not an issue. That is simply the automated patching system dropping patch hunks for files that have been removed from ungoogled-chromium.

2- running the following command results the following message, how to solve the issue? command: dpkg-buildpackage -b -uc result:

You have LLVM-16 packages installed. None are listed in the set of commands you gave, but they must have been either present on your system beforehand, or installed as dependencies of one of those packages. Make sure that you have only LLVM-19 packages installed. A combination of the two will result in an old linker reading code from a new compiler, which doesn't work.

Hello @iskunk and thanks for reply,
how to Make sure that I have only LLVM-19 packages installed?

[iskunk]

how to Make sure that I have only LLVM-19 packages installed?

You'll need to review the list of packages installed on your system, using e.g. dpkg -l.

Thanks for the @iskunk advice,
removing older llvm fixed the following issue
LLVM gold plugin has failed to create LTO module
but NOTE
do not remove libllvm18:amd64 which is required for rustc (removing it will remove rustc)
after fixing the above issue, I continued building process but I faced the following clang warnings, which one is issue and how to fix?

Generally, if the issue is only a warning and does not prevent the build from completing, it can be ignored. Some of those warnings are familiar and have always been present in the build.
