Chromium for Ubuntu

[MauryG5]

By chance I re -examined the Hardisk where I had installed Ubuntu 20.04, I had dismantled it about 3 years ago as it had too many small bugs and in the meantime Debian 11 had arrived which I had liked much more than Debian 10 and so I went to Debian. I noticed with my great surprise that in the meantime, after years, they finally resolved those ugly and annoying bugs that compromised the proper functioning of Firefox and that did not work completely working Thunderbird. I said incredible Wow, considering how little I see used Ubuntu in our Cominita Power, compared to Fedora and Debian above all. I must say that now I am using it again with good satisfaction, however, I miss the only thing and that I cannot use Chromium despite being Ubuntu a direct debian derivative. I was wondering and I would also ask Raptor that I take care of Chromium, is it not possible to have repositories compatible for Chromium? I tried to use those of Debian 12 before and 11 after but nothing. I managed to install the key, the repositories, on the other hand, obviously do not go even if in reality when I try to update after putting the reposoarths, he loads them almost all except one that ignores and I think it happens because they are not the right ones for Ubuntu. I was wondering if there was a way, as Ubuntu was a Debian derivative, to be able to install Chromium too ...

I am trying to build Chromium from 0, following the wiki/raptor guide but unfortunately I blocked myself in the part where you have to enter the exact version of the Clag compiler that Chromium uses. Raptor recommends using the specific version of the moment and from a link where to see it and the link shows this result: Clang_revision = 'LLVMORG-20-ARST-9764-GB81D8E90'

The problem is that it does not work in every way, whether I take it as it is, it gives me error of syntax because it only wants it to numbers, entering only the numbers I see. I can't understand how to take this number of clan version, to give it correctly. I also searched on the web but I can't find it in the same way. The mistakes that gives me are always the same:
Unable to connect to a repository at url 'https://llvm.org/svn/llvm-project/llvm/trunk'

Access To '/Svn/LLVM-PROJECT/LLVM/TRUNK' FORBIDDEN
Does anyone know how to get this correct number of Clag Version?

Hi
I am  using Netsurf plus duckduckgo-htmlsearch because native libre firmware on gles1.

[MauryG5]

Hi, I don't understand how I can get the number I need from this information you are giving me...

[atomicdog]

LLVM switched from svn to git.

https://github.com/llvm/llvm-project

[MauryG5]

Yes, I too had come to see that git screen, only I don't know where to get the number that is requested of me... I don't understand where to find this number that he is asking me...

[atomicdog]

Looks like that tag isn't from the main LLVM git but chromium has their own repo of LLVM.

Here's a recent build log that shows what you can do.

https://chromium.googlesource.com/chromium/src/+/main/docs/updating_clang.md

I think this might work:

Code: [Select]

# git clone https://chromium.googlesource.com/external/github.com/llvm/llvm-project
# git checkout llvmorg-20-init-9764-gb81d8e90

[MauryG5]

So excuse me, do you mean to tell me that I should replace the original line that Raptor gives in his wiki guide, that is the line of the depot tools that says:

$ git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

and insert instead of this the one you mentioned, that is:

# git clone https://chromium.googlesource.com/external/github.com/llvm/llvm-project
# git checkout llvmorg-?20-init-9764-gb81d8e90?

After when you have to insert the part dedicated to LLVM/CLANG, inserting the code: 20-init-9764-gb81d8e90, at that point it should recognize it... I don't know, I had understood that in this part it wants a series of numbers and that's it, then I don't know for sure if inserting that part that you tell me instead of the one reported in the guide, changes everything... I have to understand this fundamentally...

[atomicdog]

No, that's a different section in the wiki, you still need the helper programs in depot_tools.

The sections below LLVM/Clang is what needs to be updated/modified. Replace the SVN checkout commands with git clone and checkout commands

The number is a git tag. It tells git which exact version to checkout/use so you can compile a known good version.
The 'CLANG_SVN_REVISION=35769' number in the wiki will no longer work since LLVM doesn't use SVN anymore.

[MauryG5]

Ah ok then let me understand, okay replace the commands in the checkout wiki with the ones you gave me, but the command export CLANG_SVN_REVISION, which is immediately after entering the created directory of CHROMIUM, what do I have to do at this point? Thanks for your patience and collaboration!

[atomicdog]

Replace this:

Code: [Select]

$ cd $CHROMIUM_DIR
$ export CLANG_SVN_REVISION=357692 # Check the above link for the current version
$ svn checkout --force https://llvm.org/svn/llvm-project/llvm/trunk@$CLANG_SVN_REVISION llvm
$ svn checkout --force https://llvm.org/svn/llvm-project/cfe/trunk@$CLANG_SVN_REVISION llvm/tools/clang
$ svn checkout --force https://llvm.org/svn/llvm-project/compiler-rt/trunk@$CLANG_SVN_REVISION llvm/compiler-rt
With:

Code: [Select]

$ cd $CHROMIUM_DIR
$ git clone https://chromium.googlesource.com/external/github.com/llvm/llvm-project
$ git checkout llvmorg-20-init-9764-gb81d8e90

[MauryG5]

Perfect now it's clear thank you very much, I'll update you as soon as I get on the computer these days.

[MauryG5]

I performed the first of the 2 commands and downloaded me 3.4 GB of files and therefore everything went regular, when I performed the command:
$ Git Checkout LLVMORG-20-INART-9764-GB81D8E90
gives me this output:
Fatal: it is not a git repository (nor is any parent to the point of Mount /)
I stop at the limit of the filesystem (the Git_discovery_across_filesystem option is not set).

[atomicdog]

Sorry, you need to change into the llvm-project directory first (or specify which directory in the git checkout command).

Code: [Select]

$ cd $CHROMIUM_DIR
$ git clone https://chromium.googlesource.com/external/github.com/llvm/llvm-project

$ cd llvm-project

$ git checkout llvmorg-20-init-9764-gb81d8e90

[MauryG5]

Yes, after this specification you made, I worked, I continued with the CMAKE command, from the Chromium_dir/Llvm -Protject/LLVM_BUILD $ path, I performed: Cmake -Dcmake_build_type = release -Dllvm_Targets_to_build = "PowerPC" -G "Unix Makefiles" .. /LLVM.
It initially gave me error on the CMAKE command as it told me that I had version 3.16 and he wanted at least 3.20. Hop proceeds to install version 3.20 after which the CMAKE command started. It seems that some things have not found them but I don't know if it is just things about other architectures or files that are needed for me ...

However I would like to try to give the make -up command for the compilation, but I will do it tomorrow or after tomorrow that it is now late from me and I know it takes a long time to fill in Chromium if it should leave so I wait ... if you think there is some Anomaly, however, from this output let me know and thanks for your help, having reached here already is a great thing for me ...
