OSError while installing through nimble

[zetashift]

I'm on Windows 10, and while using the command nimble install gintro I'm getting the following error:

preparing gintro nimgrab.nim(35) nimgrab nimgrab.nim(16) syncDownload urldownloader.nim(413) downloadToFile oserr.nim(110) raiseOSError Error: unhandled exception: The specified protocol is unknown. [OSError]

zetashift: update your Putty client

As it still seems not to work for you:

Try if a plain command like

exec("nimgrab 'https://raw.githubusercontent.com/StefanSalewski/oldgtk3/master/oldgtk3/gobject.nim' gobject.nim")

works for you. If it does not work, maybe try with other download files.

Generally that should work.

If we do not get that working, we have a bunch of possible solutions:

• Add the needed files from oldgtk3 to gintro package

• Download full oldgtk3 with a git clone command.

• Require full oldgtk3 from nimble before install.

But the main question is, if after a successfully download gintro would work at all for Windows. I will investigate this issue further if someone is really interested of USING gintro on Windows, that is creating a larger GTK3 application.

I figured it out! Removing the single quotation marks around the 'https://raw.githubusercontent.com/StefanSalewski/oldgtk3/master/oldgtk3/gobject.nim' (and the others)
in gintro.nimble fixed it for nimgrab and wget. Now I'm just getting libglib-2.0.0.dll missing error but that's just a dependency I haven't installed yet.

Thank you :D

Alright so far:

1. Remove the quotation marks from the download url
2. Install msys2 and run: pacman -S mingw-w64-x86_64-gtk3 then run: pacman -S mingw-w64-x86_64-python3-gobject to get the other required dlls's.

Now I get the following error:

Great.

GtkSource is for GtkSourceView, which is used for editors like GEdit, Aporia, NEd...

It may be that you have to install it separately for your Windows GTK, maybe there is a separate package. But most people should not need GtkSource, basic examples should work without it.

So generally you could skip/remove line 1717 (main("GtkSource")) from file gen.nim.

Unfortunately I don't know how you can do it locally now -- with the older package variant it was easier, because that used "nimble prepare" followed by "nimble install" both executed from inside gintro directory. That was available for nearly one year, but no one has tried. Now it is gone, sorry.

[zetashift]

It worked holy snap!

So after the previous steps I commented line 1717 out and then I had to copy-paste the .nimble from the gintro folder to my /AppData/Local/Temp folder.
Then I had to copy-paste the gintro folder(containing all the relevant nim files) to my /.nimble/pkgs/gintro-0.4.0/

All the examples work. Thanks again for your time :D.

[StefanSalewski]

Great.

I have just created a nimgrab issue about the single quotes. It was a bit strange that it worked fine for Linux. I should be able to push a updated gintro.nimble without the quotes in a few days, then a plain "nimble install gintro" should work.

Can you tell us how you have installed the GTK libs for your Windows 10?

And what was special with package GtkSource?

I would like to add that information to tutorial.

[zetashift]

For the GTK libs I did according these instructions(https://www.gtk.org/download/windows.php):
Install MSYS2
In the msys2 cmd I entered:
pacman -S mingw-w64-x86_64-gtk3
Then for some other necessary depencies(girepository.dll) you need to do:
pacman -S mingw-w64-x86_64-python3-gobject

I'm not sure about the GtkSource error, as I don't know that much about GTK.

[StefanSalewski]

Thanks for that info.

From GTK maling list I just got these additional info:

Yes they already found MSYS2 which contains the packages:
https://github.com/Alexpux/MINGW-packages/blob/master/mingw-w64-gtksourceview3/

I will try to add this info to tutorial and fix nimble script in the next days.

I think the full installation instructions for Windows should be added to the Readme.
It is enough to install 2 packages: glade(will get gtk3 as dependence) and gobject introspection(python not needed)
Also you can install git from msys(needed for nimble)

�pacman -S mingw-w64-x86_64-gobject-introspection
pacman -S mingw-w64-x86_64-glade  
pacman -S git

Then you need to add 2 path to env

C:\msys64\mingw64\bin // for libs
C:\msys64\usr\bin // for git (git is not mingw64 package)

All works ^^
