DC environment variable is not recognised

tastyminerals commented 2 years ago

Optionally set the environment variable DC if you wish to use another compiler than the DMD known by the system.

I have my shell env var set to

$ echo $DC                                                                                                  
/usr/local/bin/ldc

but make still attempts to use dmd.

WebFreak001 commented 2 years ago

no mention of $DC or ${DC} in the makefile anywhere, so probably just not implemented. Windows has it at the start though.

tastyminerals commented 2 years ago

I managed to get it working by modifying the makefile though.

What modifications did you perform inside the makefile? I'm having this same problem and I can't find any workaround

tastyminerals commented 2 years ago

Actually just minor changes:

ldc is aliased to /usr/local/bin/ldc which is a symbolic link to an actual ldc2 binary.

Well it did the trick for me as well, thank you!
