digitalmars.D.learn - How to compile with GtkD

reply mark <mark qtrac.eu> writes:
According to the GtkD web site https://gtkd.org/ this GUI library 
is cross-platform, so hopefully just what I need.

The introductory blog 
https://gtkdcoding.com/2019/01/11/0000-introduction-to-gtkDcoding.html explains
how to install and get started with GtkD on Windows (which I plan to use later
on), but right now I want to start on Linux and I'm stuck.

I have LDC in $HOME/opt/ldc2-1.19.0-linux-x86_64 with the bin/ 
dir in my path, and GtkD 3.9.0 in $HOME/opt/GtkD3

I am trying to build a simple "hello world" app (from the 
gtkDcoding blog) in $HOME/app/d/gtktest (which is a dub init 
created directory) and have this dub.sdl:

name "gtktest"
description "Gtk Test"
authors "Mark"
targetType "executable"
dependency "gtk-d:gtkd" version=">=3.9.0"
importPaths "$HOME/opt/GtkD3"
libs "libgtkd-3"

The error I get is:

$ dub
Performing "debug" build using /home/mark/opt/bin/ldc2 for x86_64.
gtk-d:gtkd 3.9.0: target for configuration "library" is up to 
date.
gtktest ~master: building configuration "application"...
Linking...
/usr/bin/ld.gold: error: cannot find -llibgtkd-3
collect2: error: ld returned 1 exit status
Error: /usr/bin/cc failed with status: 1
/home/mark/opt/bin/ldc2 failed with exit code 1.

$ cd ~/opt/GtkD3
$ ls *.a
libgstreamerd-3.a
libgtkd-3.a
libgtkdsv-3.a
libpeasd-3.a
libvted-3.a

I also tried specifying libs as "gtkd-3" and had the same problem.

I can run $HOME/opt/GtkD3/TestWindow and it works fine. And I can 
also build it in $HOME/opt/GtkD3/demos/gtkD/TestWindow. However, 
it uses a dub.json with "dependencies": { "gtk-d:gtkd": {"path": 
"../../../" }, } and I don't know what the dub.sdl equivalent of 
this is. (I prefer .sdl to .json.)

Unfortunately it didn't because I have locally installed LDC and 
GtkD.

Generally, for development I prefer to install (and on Linux 
build) languages and libs myself rather than using system 
versions.

What I really need is to know how to change my dub.sdl to send 
the right arguments to ldc2.

Turns out I didn't need to add lines to dub.sdl at all. So my 
dub.sdl is now just:

name "gtktest"
description "Gtk Test"
authors "Mark"
targetType "executable"
dependency "gtk-d:gtkd" version=">=3.9.0"

The solution was to do this:

$ dub add-path ~/opt/GtkD3/

After that it does static builds, which is great, gives me 
self-contained executables.

Libraries should be passed to dub / ld without the lib prefix, so that 
last line would become: libs "gtkd-3"

Since dub will build a copy of the libraries listed as dependencies, you 
can either remove the dependency line, or the importPaths and libs 
lines. Since now you are linking against both the library build by dub 
and the one on your system.
