setup the env via yum (I have installed ldc).

I wrote a blog post at https://aberba.gtihub.io which has Fedora users covered. But somehow GitHub pages is not working so you can find it here too https://github.com/aberba/aberba.github.io/blob/master/_posts/2016-08-20-hello-world-app-with-the-vibe.d-web-framework.md

Hi, still no progress. It seems to be accessing some sha module and then not finding symbols.
I also tried cgi.d and that also wont work ia a "hello world" friendly way.

I used DMD compiler for the tutorial, you are using GCC which might be the problem. GCC compiler seems too outdated. Try using DMD

Oh, I see. Actually it got installed auto-magically during dub installation I guess. Now I installed dmd with the script mention on the dlang download page.
curl -fsS https://dlang.org/install.sh | bash -s dmd

I ran dub again. Here's the error this time!

Make sure you install all the vibe.d dependencies. You can refer to my blog post at https://aberba.github.io/2016/hello-world-app-with-the-vibe.d-web-framework/ under the "Setting up your development environment" section.
