Hi, all.
So I see that there is an Ubuntu dmd that has "x86_64" as the "CPU" column. Before I install Ubuntu to great disappointment, does this mean that I get a 64 bit executable, or does it just mean that the compiler itself is a 64 bit application?
Thanks,
Charles.

The Linux version of DMD can generate 64bit binaries.

Pass the compiler -m64 to generate 64bit code, I do not believe it defaults to 64 file format even on the 64bit executable, but maybe that changed and someone can update me on it.

The documentation page for the compiler says that it does default to -m64 on x86_64:
