Re: Linking to C

[Mike Chaten]

Any options with just one dash afaik (ala -L) will pass through to dmd.

Re: Linking to C

[Mike Chaten]

How are you compiling & linking the files? I've gotten this error before
when I forgot to include a file in my compilation (in your case
libraw_c_headers)

/usr/bin/shell & Ubuntu 10.10

[Mike Chaten]

I filed issue 5047  when
I upgraded to Ubuntu 10.10 from 10.04. The problem revolves around the fact
that, by default, 10.10 installs byobu  which
contains it's own /usr/bin/shell.

According to the docs, shell is a "Simple command line shell". While this
might be very useful for sh support on windows, linux provides sh support in
every distro. Is there a use for shell to someone using dmd that I am not
aware of? If not, can this be removed from the deb/rpm for future releases?

Thanks
-Mike

Re: First big PITA in reallife D project

[Mike Chaten]

I doubt a new version of dmd will be out until November at the earliest, as
there is no dmd beta out at the moment.
In the mean time, you should be able to download the latest source code of
phobos at
http://www.dsource.org/projects/phobos/changeset/head/trunk?old_path=%2F&format=zip
and build the code.

I'm not familiar with dmd under windows, but I believe you can just replace
the phobos .lib/.dll/.whateverextension file with the one you built.
