  1. Anyone has built gdc-11 in the mingw64 environment since

No patches are required, it is all upstreamed if you use the 
right settings.


See my comment here:

https://github.com/brechtsanders/winlibs_mingw/issues/48#issuecomment-1044782237


(the maintainer of that repo wants to do binary packages but with 
pthreads, which has some missing headers. should be an easy patch 
but i haven't gotten around to it and i guess iain hasn't yet 
either. but with the configure command i pasted there you can do 
it)


  2. How we might go about creating a pacman package for gdc-12 
since it requires an existing D compiler?


i don't know anything about this.

Re: gdc --version doesn't indicate which D front-end version it's compatible with

It would be far more helpful if running `gdc --version` gave 
some indication of the version of D it's aligned to (which was 
2.076 last time I checked).


It is more complicated than that because gdc has a bunch of 
backported things from newer versions too.


You might be best off just trying it and seeing if your code 
works.

compilation terminated.


The PATH needs to include the normal mingw64 bin path as well as 
the path for gdc.


Though I haven't tried the download here I got mine successfully 
building and running from the same source code..

Re: Remove elements from char[] throws error

DMD compiles this fine. But GDC throws the following error:


gdc bundles an older version of the std library, so that 
particular overload was probably added more recently.


You could possibly `cast(ubyte[]) a` in there to select a 
different overload.

Re: Appender example doesn't work with GDC. GDC bug?

For the line "Writeln(w[]);" GDC reports "error: no [] operator

I think that is just a broken example. Pretty sure it should be 
`w.data` instead of `w[]`.
