Your version of harfbuzz is too old. Update or use the linux binaries rather than building from source (though note that the linux binaries require a relatively recent version of freetype as well).

[dcow]

I installed harfbuzz from source. Why would the top of tree be too old?

[kovidgoyal]

The missing symbol in harfbuzz hb_ft_font_changed means that you either did not compile harfbuz againt freetype, the freetype version you compiled it against is too old, or you have not set LD_LIBRARY_PATH or similar to ensure kitty loads the newly compiled harfbuzz

[dcow]

It looks like my harfbuzz was not configured properly. It's aware of freetype now and everything works. Thanks!

I am getting the same issue, but i dont know how to resolve.

I have installed harfbuzz-2.6.0 in $HOME/Downloads/harfbuzz-2.6.0 and compiled successfully with make & make install

[kribakarans]

Is there any comments an the above conversations ?

[dufferzafar]

@dcow can you please describe how exactly you fixed this problem? Did you pass any parameters to harfuzz's ./configure to make it use freetype?

[dcow]

According to my history, no. But I don't really remember. I think it was a missing dependency. I think this line (copied from the harfbuzz BUILD.md) fixed it:

sudo apt install gcc g++ libfreetype6-dev libglib2.0-dev libcairo2-dev

Followed of course by rebuilding. I don't think you need to rebuild kitty, just harfbuzz. Here's my history after the above command if it helps:

sudo apt install -f
make clean
./configure
sudo apt install autoconf automake libtool pkg-config ragel gtk-doc-tools
make clean
git clean -fxd
./autogen.sh
./configure ls
^^^ pretty sure this is just a typo which is why I try again
git clean -fxd
./autogen.sh 
./configure
make
sudo make install
kitty
