couldn't make it work on linux

[carlhung]

when running swift test
i got this error:

error: link command failed with exit code 1 (use -v to see invocation)
/usr/bin/ld.gold: error: cannot find -lskia_skiakit
/usr/bin/ld.gold: error: cannot find -lfreetype
/usr/bin/ld.gold: error: cannot find -lfontconfig

Thanks for reporting this. Which distribution are you using?

To fix the first linker error you have to install this lib (has instructions): https://github.com/ungast/SkiaKit
For the other two you will need to find binaries for your distribution.

I did install the lib. And saw it in the path of ‘/usr/local/lib’. I am using WSL2 with Ubuntu 20.04.
new WSL2 supports GUI in windows. That’s why I want to use this repo to try.

[UnGast]

That's interesting. Maybe try moving the library to /usr/lib instead.
sudo mv /usr/local/lib/libskia_skiakit.a /usr/lib/libskia_skiakit.a

[carlhung]

after moving, i got these error messages:
/usr/bin/ld.gold: error: cannot find -lfreetype
/usr/bin/ld.gold: error: cannot find -lfontconfig

Nice, we are progressing.

Now please try installing the two missing libraries like this: sudo apt-get install libfreetype6 libfontconfig1

[carlhung]

no, already installed.

i found the dependencies to install for skia.
but new error:

Did you build the skia binary yourself or did you download one?

[carlhung]

downloaded

Strange. I currently have to prepare for exams, so I have no time to look into it. Looks like I messed something up with the binaries. I will look into as soon as I have more free time.
