Dynamically calling shared objects from statically build executable allowed
Hi, while dynamically calling a shared object from a statically build executable on linux, both LDC and DMD fails with a non-zero code 139. In my productive system the SO is written in C++, for reproduction I wrote a sample SO in D. You can find the example here https://github.com/ldc-developers/ldc/issues/3310 Is this a bug with LDC and DMD, or is it not allowed to dynamically call a SO from a statically build executable on linux? Background: The SO file I get from third party, while the executable I develop. I need to run the executable on a distroless docker image (SCRATCH), therefore I try to reduce system dependencies on my side by building a static executable. PS. DMD even fails without the static switch with: Aborting from src/rt/sections_elf_shared.d(480) DSO being unregistered isn't current last one. Kind regards André

There's absolutely no need for an IDE to be written in D (particularly one that supports RAD -- what would that use? GtkD?). For one thing, it's a massive project for which the D team does not have the resources to achieve. For another, there are already several popular IDEs and text editors for which plugins have been developed by community members. It would be a waste of time and energy for the D team to work on an IDE project. If someone is inspired to write an IDE in D (and some have been in the past), nothing is stopping them.

Making an entire IDE would be a lot of work. Making plugins for existing editors is already time consuming, and is less work than building a complete solution. Given how powerful regular editors can be, whether it's VSCode, Vim or Emacs, plugins make for a good compromise bewteen the time spent making the plugin, and the result you get.

Everything what I could find and what works "out of the box" has nothing to do with D and is made work trough plugins mostly. That is disappointing. S

Re: How to compile with GtkD [solved]
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.

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.

How to compile with GtkD
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/-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.)
