Set clang-3.8 as default

I have installed clang 3.0 and clang 3.8:

$ sudo update-alternatives --config clang

update-alternatives: error: no alternatives for clang.

How can I set 3.8 as /usr/bin/clang?

Solution 1:

sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.8 100

sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.8 100

Solution 2:

sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-8   81 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-8    --slave /usr/share/man/man1/clang.1.gz clang.1.gz /usr/share/man/man1/clang-8.1.gz --slave /usr/bin/clang-tidy clang-tidy /usr/bin/clang-tidy-8  --slave /usr/bin/clang-format clang-format /usr/bin/clang-format-8
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-6.0 60 --slave /usr/bin/clang++ clang++ /usr/bin/clang++-6.0  --slave /usr/share/man/man1/clang.1.gz clang.1.gz /usr/share/man/man1/clang-6.0.1.gz --slave /usr/bin/clang-tidy clang-tidy /usr/bin/clang-tidy-6.0 --slave /usr/bin/clang-format clang-format /usr/bin/clang-format-6.0

These commands will add 2 entries and default selected as clang-8. You can configure using

sudo update-alternatives --config clang

This will update clang, clang++, man pages, clang-format, clang-tidy.

Solution 3:

Try:

sudo update-alternatives --config cc

And it will present the list of options for you to choose.

make utility uses the command cc to compile, which is actually a link to gcc, clang etc.
