digitalmars.D - SCons and D

It seems I am on a bit of a roll getting changesets relating to D
support for SCons into an appropriate state so that they get merged
into the mainline SCons repository. So maybe now is a time to get any
"pet peeves" with D support in SCons fixed.

For myself, I am currently working on a new tool "dub" to handle
getting dependencies from the Dub repository. It works for unit_testing
in my D projects, but I need to write some proper SCons tests before
submitting a pull request to the SCons mainline.

Anyone wanting to try the dub tool now will need to use dub.py from my
SCons_D_Experiments Git repository on BitBucket or GitHub.

(The dmd, ldc, and gdc tools in that repository are just mirrors of
what is in the mainline Mercurial repository on BitBucket, unless some
experiments rather than bug fixes are needed.)

I'd like to give this a try, but do you have a link to your 
repository?

When I create a shared library I get an error message.

SharedLibrary('lib2', ['lib2.d'])

leads to

dmd -oflib2.so -shared -defaultlib=libphobos2.so 
-L-soname=lib2.so lib2.os
Error: unrecognized file extension os

Apparently using the .os extension works for C but not with dmd.

Hummm=E2=80=A6 there is a passing test for creating shared objects, the tes=
t
must be wrong in some way.

Can you email me a small project that exhibits the problem for you, and
I will add it to the test suite.

I sent you an email with my code. The solution I found was to use

SharedLibrary('lib2', ['lib2.d'], SHOBJSUFFIX='.o')

instead of the above SharedLibrary call (which I took from the 
documentation).

Certainly that works, but it would be better that you didn't have to do
that. This should work "out of the box" without hassle. Also the tests
in the test suite for the D tools do not have this and they pass. This
would lead to the hypothesis that the D compilers are behaving
differently for you and for me, which I suspect means we are working on
different platforms, which would indicate a gap in the CI testing for
SCons.

I sent you another message. I fixed it by adding one line to 
dmd.py to set that variable.
