Hello,

I am trying to run a Hello World program but I have trouble setting up gtkD. I first tried building gtkD the manual way (following the wiki) by downloading it from GitHub (commit 317b811) and running rdmd Build.d. While I can make a Build.exe, running it results in this error:

generated/gtkd\pango\c\types.d(2159): Error: struct pango.c.types.PangoCairoFontMap conflicts with struct pango.c.types.PangoCairoFontMap at generated/gtkd\pango\c\types.d(1217)

master seems to be broken, but the latest release should work:
https://github.com/gtkd-developers/GtkD/releases/tag/v3.6.5
https://gtkd.org/Downloads/sources/GtkD-3.6.5.zip

When I try the 64-bits version rdmd -m64 Build.d it gives this error:

Error: can't run '\bin\link.exe', check PATH

For 64bit builds on Windows dmd needs the Windows SDK, and the paths to
the SDK to be properly set in sc.ini. The dmd installer should do this
automatically if the SDK is installed.

More information here:
https://wiki.dlang.org/InstallingDMDon64-bitWindows7(COFF-compatible)

I also tried putting it in my DUB dependencies:

"dependencies": {
	"gtk-d": "~>3.6.5"
},

But then when I run dub build --force it gives this output:

How do I fix this?

Due to a dmd/optlink bug we can't build debug builds of GtkD on Windows.
Pass --build=plain to dub so it does a regular build.

Thanks for your response.

I can now compile and build an executable, but running it gives a pop-up saying (translated):

Can't find entry point of procedure FT_Get_BDF_Property in DLL C:\Program Files\Gtk-Runtime\bin\libfontcongif-1.dll.

When I run it via Eclipse it outputs to the console:

object.Exception@......\AppData\Roaming\dub\packages\gtk-d-3.6.5\gtk-d\generated\gtkd\gtkd\Loader.d(125): Library load failed (libgdk-3-0.dll): The specified module could not be found.

It looks like you are using the 64bit version of the Gtk Runtime, did
you compile gtkD and the executable as 64bit?

I made an error in copying the error text. The DLL is not in:
C:\Program Files\Gtk-Runtime\bin\libfontcongif-1.dll
But in:
C:\Program Files (x86)\Gtk-Runtime\bin\libfontcongif-1.dll

Both of those directories exist though, I installed both the 32-bit version and the 64-bit version of the runtime. I also tried to compile both the 32-bit and 64-bit version, I don't know which version dub uses.

Trying manual again

I uninstalled the 64-bit runtime, cloned the repo and built without the -m64 flag. The build was successful this time, but I'm not sure about this step:

4. Copy GtkDExtractionDir\src to dmddir\src\gtkd

I copied the src folder from C:\D\GtkD\src\, but it says:

dmd hello.d -Lgtkd.lib
hello.d(1): Error: module MainWindow is in file 'gtk\MainWindow.d' which cannot be read
import path[0] = C:\D\dmd2\windows\bin\..\..\src\phobos
import path[1] = C:\D\dmd2\windows\bin\..\..\src\druntime\import
import path[2] = C:\D\dmd2\windows\bin\..\..\src\gtkd

MainWindow.d is in C:\D\GtkD\generated\gtkd\gtk which I didn't copy, so I copied \generated\gtkd\ as well. I replaced the files that were in conflict with the already existing files. Running dmd hello.d -Lgtkd.lib gives:

OPTLINK : Warning 9: Unknown Option : NOIGTKD.LIB

Demos

I tried dub run --build=plain on the demos in the repo:

DemoCustomList: ..\..\..\generated\gtkd\gtkd\Implement.d(351,2): Warning: statement is not reachable

The linkers used differ between the 32 and 64 bit versions of dmd. Which
unfortunately use different flags to link with a library.
It's -L+gtkd.lib when building a 32bit application and -Lgtkd.lib
for 64bit. (I've updated the wiki to hopefully make that clearer)

Using -L+gtkd.lib I could succesfully compile and run a hello world program.

It turns out that the Can't find entry point of procedure FT_Get_BDF_Property in DLL C:\Program Files (x86)\Gtk-Runtime\bin\libfontcongif-1.dll happens when I run the .exe in a folder containing libfontcongif-1.dll. That file was still there from when I tried DLangUI I think.

Most of these errors would indicate you are using an old version of Gtk+
or at least GtkD finds some old version that is still installed someware.

The gtk_menu_attach: assertion 'left_attach < right_attach' failed for
example was fixed in Gtk+ 3.18, while the latest installer on gtkd.org
is for Gtk+ 3.22.

I have "Gtk+ Runtime version 3.8.1-2" published by "GtkD Developers" installed on "30-May-17". I don't believe I got it from gtkd.org so I might run the demo again after reinstalling it from there.

Anyway thanks for the help, I can now compile and run the hello world program both with dub and dmd -L+gtkd.lib so I'll try making a simple application this weekend. :)
