digitalmars.D - Can I distribute the DMD compiler in an app of mine?

Hello!

I believe the project will start out open-source because I will 
be using Qt Creator, KaTeX, Markdown for the frontend.  And Qt's 
commercial license is too pricey for now.

The kernel though of my app will be a library written in D, for 
which (at a low level) the user can use the library in D itself 
(using D as a "host language"), or alternatively type in some 
specialized English, which will then be translated into 
equivalent D statements that use the library.

Anyway, obviously I need to include the DMD compiler itself so 
that the users get a nice installation experience.  Do we have 
permission to do such a thing?

If not, is there another D compiler that allows this?

It's boost licensed.

DMD is Boost licensed meaning yes, you can include it.

For GDC, it's GPL licensed. LDC is Apache licensed. I'm not sure how that would 
apply to your app's license.

Awesome.  Thank you!  Is there any reason I should switch to GDC 
or LDC?  It would be nice to have the speediest compilation time, 
for small-to-medium sized user codes + library usage, but the 
library won't change usually.

They each have their own strengths and weaknesses. You'll need to evaluate that 
in the context of your requirements.

  Personally i would be against this. Not because licensing 
issues, but rather for bloat.

  I have a similar preference for games that include a bunch of 
dependency libraries, which can be far larger than the game 
itself and distributed in hundreds of games means potentially 
Gigabytes of repeated portions that are not needed and can't be 
compressed or removed.

  But that's just a personal opinion. It's not like you're 
including a 700Mb installer of .Net  in order to run a 200k 
program.
