dmd build instructions from source don't work anymore

On my machine g++ is in /usr/bin and is actually clang, although not as a symbolic link, as a slightly differently configured executable. Don't really know what apple's thinking here was.

Which page is this that needs updating? I don't see the necessary info in http://wiki.dlang.org/Building_DMD, but I might have missed it.

NOTE: it's on a new laptop; not sure whether build rules implicitly assume (maybe by error?) that something should be there beyond g++/clang/dmd but the error message i get isn't helpful. 1) already have a version of dmd installed (relatively new requirement) yes (via homebrew; on a new laptop): dmd --version DMD64 D Compiler v2.067 2) have a working g++, whether of clang or gcc variety? yes, I've built llvm from source, etc; both g++ and clang seem to work.

note, that this seems to be only happening on master: if I checkout another tag (git checkout v2.067.1-b1 or any other I've tried) it builds fine. So it must be a very recent regression On Mon, May 11, 2015 at 5:55 AM, John Colvin via Digitalmars-d < digitalmars-d@puremagic.com> wrote: > On Monday, 11 May 2015 at 12:25:27 UTC, Daniel Murphy wrote: > >> "John Colvin" wrote in message news:jsnuhemrispqiwvwlfde@forum.dlang.org. .. >> >> Do you >>> 1) already have a version of dmd installed (relatively new requirement) >>> >> >> Yeah, it's this.

I found the culprit by bisection:
hash: 50b7697...

HEAD is now at 50b7697... Merge pull request #3970 from yebblies/idgend2

https://github.com/D-Programming-Language/dmd/commit/aa8a7b3dcf985c8332783961c1dd7bc598ec36c5

it builds fine right before this, and fails with this

NOTE: I had 'export CC=gcc' in my environment, leading to this behavior (ie worked fine until 'Merge pull request #3970 from yebblies/idgend2', and breaks after that pull request is merged). If I 'unset CC' it works. But IMO it should work even when user has set CC (or at least provide a better error message) Also I notice CC is set to 'g++' in posix.mak which is untypical (instead of gcc for example) Other users could face the same issue which is hard to debug.

Yep.
