It seems that the Ubuntu "snap"s are not being updated for a 
few years??


It seems some of my problems are related to the very old 
versions I got with snap :(


dub  - 1.19.0 (seems to be from Oct 2020)
ldc2 - 1.24.0 (seems to be from Oct 2020)
dmd  - v2.090.1 (Feb 2020)

I feel stupid for choosing snap (I don't use snaps, just felt 
like a convenient thing to try this time!).


I will try using latest of everything on Linux (on Mac I think 
I was already fine on latest) and hope it works better.


What's worked for me on Ubuntu is to download the .deb from the 
downloads page and sudo apt install ./dmd_2.106.0-0_amd64.deb. 
Always have the latest release and never have problems.

My build options are currently:

```
"dflags-dmd": [ "-v"],
"lflags": ["-ld_classic"]
```

I tried some variations but nothing worked.


Previously for macOS it was required to write “export 
MACOSX_DEPLOYMENT_TARGET=11”


Also remove dmd/dub first. Then try to use LDC from official 
GitHub Release. And update the PATH variable. Maybe script from 
the official download page is doing the same - idk.


At least this is what I’m using on macOS (but M1). DMD just 
doesn’t exist for me anymore)

This should do it:

``--combined --build-mode=allAtOnce``


I run this:

```
dub build --combined --build-mode=allAtOnce

Still got an error:

Thanks for letting me know! It's good to have other's

Looks like I got it working with the overly complicated Ubuntu 
instructions (I used snap instead before because it was just 
"snap install dmd" rather than 5 large shell commands!)... if 
that still gives me trouble I will stick with the sh file you've 
linked (there were so many options for installing the compilers 
and I had to pick the worst one I suppose).

It should work ok if you build and link in a single step with

DC is an environment variable that should point to the D 
compiler.


As a variable this particular one has some sort of story with 
it, I just can't remember it.


We'd need to know what is requesting it to find out how to 
resolve it. Please try again with ``-v`` that should tell us

That output was already with -v enabled. It just didn't show 
anything else relevant.


But I found an issue from a few years ago about that:

https://github.com/vibe-d/vibe.d/issues/2677

That's why I figured out I was using very old versions of 
everything on Linux.

I personally never used GDC since I develop on Windows 99% of the 
time (the other time is only used on the other platforms when I 
need to develop specific things for them).



The error you're seeing is related to a DC variable. The D 
Compiler variable. I would guess this is a problem caused by your 
package manager when installing D.


I've been developing a game engine which does compiler execution 
for the user because it can get quite hard to understand 
depending on the size of the project.

Hi, I have been trying D for the last few days... I am only 
writing because I really, really like the language! It's 
absolutely stunning how the features it has are simple, well 
designed and at the same time incredibly advanced! All with an 
extremely fast compiler, which is almost unbelievable.


However, I faced a lot of issues which I think could be addressed 
to make others have a much better time getting started so they 
don't stop before even being able to appreciate all the great 
things about D.


First of all, if you have latest MacOS and install DMD (I tried 
several methods) it just doesn't work due to a linker problem: 
https://forum.dlang.org/post/asanawokkhqhhvryn...@forum.dlang.org


Luckily, it seems the issue was fixed 2 weeks ago, but 
unfortunately that's not released yet (so one less problem for 
newcomers).


Anyway, the workaround is to use a linker flag to make it work 
with the current DMD compiler... compiling on the CLI now worked 
with that, but then I tried to compile a dub project and faced 
the same issue even after adding the linker flag.


The error was this:

```
d: warning: pointer not aligned at address 0x1000743BE ('anon' + 
958 from 
/Users/renato/.dub/cache/myproject/~master/build/application-debug-tVTrfpmFVmiMN6SGvTQC-w/myproject.o)
ld: warning: pointer not aligned at address 0x1000743FA ('anon' + 
1018 from 
/Users/renato/.dub/cache/myproject/~master/build/application-debug-tVTrfpmFVmiMN6SGvTQC-w/myproject.o)

ld: unaligned pointer(s) for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to 
see invocation)

Error: linker exited with status 1
Error /Library/D/dmd/bin/dmd failed with exit code 1.
```

At this point I had to give up MacOS development and use my Linux 
machine.


On Linux I like using Nix for package management... when asking 
the DMD package to install, however, it seems to run the full 
test suite for the DMD compiler locally... I waited for 30mins 
before giving up. Would be nice to get instructions on how to 
install it without running the tests.


I then decided to usg GLC on Linux. That worked fine and 
installed with `apt install gdc` in a couple of seconds :).


The other compilers were also easily installable on Kubuntu using 
snap.


Now, I tried to create a HTTP server using vibe.d. I followed 
their instructions to run "dub init" and that seemed to be 
working fine until some error came up.


Here's my terminal output:

```
➜  dserver dub build

```

Really hard to get stuff working, unfortunately, and the error 
message is just not helpful.


I also tried the Language Server (serve-d) with emacs and it's 
not working properly on Linux, but seems to work somewhat (it 
shows errors but no autocompletions using eglot at least) on Mac.


I was really eager to get a D project and up and running, but due 
to these issues  I am not quite sure I will persist, 
unfortunately, as even a language like Nim (which is a bit 
similar to D in its scope) has a much better story getting 
started.


Anyway, please let me know if you have hints for some of the 
issues above and hope things like this can get better in the 
future.
