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/asanawokkhqhhvrynngd 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 Fetching vibe-core 2.5.1 (getting selected version)... Fetching memutils 1.0.9 (getting selected version)... Fetching taggedalgebraic 0.11.22 (getting selected version)... Fetching vibe-container 1.0.1 (getting selected version)... Fetching vibe-d 0.9.7 (getting selected version)...

Fetching openssl-static 1.0.2+3.0.8 (getting selected version)... Invalid variable: DC ➜ dserver ls dub.sdl dub.selections.json public source views ➜ dserver dub build Invalid variable: DC ``` 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.

All with an extremely fast compiler, which is almost unbelievable.Yeah, D has a really bad experience in MacOS. If you want to use it on mac, I suggest using LDC. And the package managers doesn't do D justice. You want to get the zip and setup the environment variables yourself, this is the best way to make it work. The "D recommended way" to install is by using the install.sh script, found at https://dlang.org/install.html 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.

Hope your game engine is coming along nicely :) 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).

Welcome! Regarding the problems with dub on OSX, that'll be due to separate build + link steps. It should work ok if you build and link in a single step with the workaround applied. 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 what is wanting it.

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. How do you tell dub to "build and link in a single step"?

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)
