hi,
In theory though you can point it at any D compiler by setting the "DC" environment variable.
i found at early morning, that by setting variable at system level(through my computer->environment setting) meson can detect d.
it is the old usual way of setting variable that i almost forgot. i'll try the DC variable thanks.# i use mason because i am stuck with dub, i got lost in documentation.
# reggae that i build from source, it works but at the end it throws exception.
