How to load Clang-13 compiler for Codeblocks on Ubuntu

(1/2) > >>

pabristow:
I have installed clang-12 OK and can compiler and link and run with it.
But when I try the analogous command for version 13
   sudo apt-get install clang-13 lldb-13 lld-13 --install-suggests

I just get

 Package clang-13 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source.

https://apt.llvm.org/  suggests that version 13 (and later) are available

To install just clang, lld and lldb (13 release):

apt-get install clang-13 lldb-13 lld-13

with same messages.

I have also found
https://packages.ubuntu.com/source/impish/llvm-toolchain-13

but don't know how to install it.

Any hints for install novice?  Thanks.

jordi:
It seems that the package is not in the repository of your ubuntu release.
You could execute the following command to verify it:
apt-cache search clang-1

Commaster:
As you can see here Clang 13 is only available in ubuntu 21.10 (Impish) and newer.

You can match your current release

--- Code: ---> lsb_release -dirc
--- End code ---
to this list and see which are available/supported.

Pecan:
Maybe this will help.

https://apt.llvm.org/

I've used the automatic installer with the <version number> parameter and it work well on Windows WSL Ubuntu

After the install, clang ended up in /usr/bin/ as clang-13<whatever>

--- Code: ---pecan@Zbook17:~$ whereis clang-13
clang-13: /usr/bin/clang-13 /usr/share/man/man1/clang-13.1.gz
pecan@Zbook17:~$ cd /usr/bin
pecan@Zbook17:/usr/bin$ ls clang*
clang++-10                   clang-check-10           clang-format-diff         clang-query-10
clang++-13                   clang-cl-10              clang-format-diff-10      clang-refactor-10
clang-10                     clang-cpp-10             clang-import-test-10      clang-rename-10
clang-13                     clang-cpp-13             clang-include-fixer-10    clang-reorder-fields-10
clang-apply-replacements     clang-doc-10             clang-move-10             clang-scan-deps-10
clang-apply-replacements-10  clang-extdef-mapping-10  clang-offload-bundler-10  clangd
clang-change-namespace-10    clang-format             clang-offload-wrapper-10
clang-check                  clang-format-10          clang-query
pecan@Zbook17:/usr/bin$

--- End code ---

pabristow:
Correct. 
https://apt.llvm.org/
For convenience there is an automatic installation script available that installs LLVM for you.

"To install a specific version of LLVM:


--- Code: ---wget https://apt.llvm.org/llvm.sh
chmod +x llvm.sh
sudo ./llvm.sh 13

--- End code ---

and got expected clang++-13 files.

Thanks.
