No file saved when running example

I am trying to get setup with Chart but am unable to get the examples working using Stack. I am running Windows 10 and have done the following things to install Cairo:

• Downloaded and installed MSYS2(x86_64-20180531)
• Downloaded and installed GTK using pacman in MSYS2 shell
• In powershell ran stack exec -- pacman -Syy
• In powershell ran stack exec -- pacman -S mingw-w64-x86_64-pkg-config mingw-w64-x86_64-glib2 mingw-w64-x86_64-cairo mingw-w64-x86_64-pango mingw-w64-x86_64-gtk3

My stack.yaml file looks like this, pulling in the extra dependencies that aren't on Stackage:

resolver: lts-13.17

packages:
- .

extra-deps:
- Chart-1.9.1
- Chart-cairo-1.9.1
- cairo-0.13.6.0
- gtk2hs-buildtools-0.13.5.0
- gtk-0.15.2

I have included Chart and Chart-cairo in the package.yaml dependencies.

When using the code in Example 1 (Easy version) stack builds without complaint. I can run the executable, which runs without error, but the PNG file is never produced.

Did you check the folder where the executable file is located? On my machine I've got PNG file in the .stack-work\install\fd0322d0\bin subfolder of the folder with the project.

I did, it wasn't there. Even when running that executable it did not appear.

I was able to get this example to run using the Diagrams backend instead of Cairo, building an svg.

Hi @mentoc3000, I'll reopen this issue. I want to keep it open for a while as a reminder that we do have issues with the cairo backend on Windows. Thanks for reporting!

Can I use haskell-chart in win10 that I got the following error?
I had installed the package Chart with "cabal install Chart".
