The tools posix.mak has recently been updated to use DMD=../dmd/src/dmd instead of assuming an already-installed system-wide dmd.

However, this has been done without also adding appropriate paths for druntime and phobos, so the build will fail:

$ make -f posix.mak ../dmd/src/dmd -m64 -ofgenerated/linux/64/rdmd rdmd.d Error: cannot find source code for runtime library file 'object.d' dmd might not be correctly installed. Run 'dmd -man' for installation instructions. Specify path to file 'object.d' with -I switch make: *** [generated/linux/64/rdmd] Error 1

For discussion thread (and a partial patch) see: http://forum.dlang.org/thread/mailman.3.1392153392.6445.digitalmars-d-learn@ puremagic.com

Tweak to DMD value in posix.mak was made in this commit: https://github.com/D-Programming-Language/tools/commit/385f9959bab520af92722b1ad4f7ce428079c02c

... almost 2 months ago, so I don't know why no one has screamed 'til now. :-P

It's dmd which needs to know how to find druntime and phobos, so I think it would be better to check-in a default dmd.conf/sc.ini to dmd/src that works for the default folder layout.

I'm not opposed to this solution, but can you comment on the potential for such a dmd.conf/sc.ini to interfere with the druntime and phobos builds which also make use of ../dmd/src/dmd ... ?

Meanwhile, I have fixed the patch I proposed to the tools' posix.mak: it works, although it could perhaps do with a bit of design thought.

Just to note, there is now a working fix that only alters posix.mak and doesn't impose changes on any other project: https://github.com/D-Programming-Language/tools/pull/117

This fixes https://d.puremagic.com/issues/show_bug.cgi?id=12205 by adding library/include paths to the locations where druntime and phobos have been built, plus a flag to prevent/suppress alignment errors in one of the builds.

In the event that the user wishes to build using the system dmd instead of the locally-built ../dmd/src/dmd, this is trivial to achieve by overriding with DMD=dmd. DFLAGS will also then be overridden with those from the system dmd.conf.
