Digitalmars D version 2 a fresh look

A few years ago I spotted the D language and was quite impressed by it, although the division of standard library, the development of a new 2.0 version and the stale state of many libraries stopped from active usage of it.

Now a lot of things changed, the 2.0 version is more or less stable and there's a GNU D compiler for this version and it's actively developed/supported, and even planned to be maintained as one of the GNU Compiler Collection. I wish it come true.

Having reviewed the specs for the D 2.0 I should admit that the language is engineered VERY thoroughly, with many features I was missing in Java and C++, it's clean and rich at the same time.

At first I was planning to use LDC compiler for D 1.0 because failed to compile GDC for MacOSX, but then I decided to start coding something useful for Linux only to study the language, and probably later there will be a viable implementation for MacOSX. The official implementation (DMD) can compile only 32-bit binaries for MacOSX, that's why I'm concerned on alternative implementations like GDC, LDC2...

LDC under ubuntu 11.10 one more try

Installed through apt llvm-2.9, downloaded trunk LDC, executed ccmake, and added -ldl to LIBCONFIG_LDFLAGS. Successfully built!

Build tango, and adjusted /usr/local/etc/ldc.conf:

// This configuration file uses libconfig.
// See http://www.hyperrealm.com/libconfig/ for syntax details.

// Special macros:
// %%ldcbinarypath%%
//  - is replaced with the path to the directory holding the ldc executable

// The default group is required
default:
{
    // 'switches' holds array of string that are appends to the command line
    // arguments before they are parsed.
    switches = [
        "-I/usr/local/include/d",
        "-I/usr/local/include/d/tango/core/vendor",
        "-L-L/usr/local/lib",
        "-L-ltango-ldc",
        "-d-version=Tango",
        "-defaultlib=tango-ldc",
        "-debuglib=tango-ldc"
    ];
};

LDC under Ubuntu 11.10

Install llvm 2.9 from repo, ccmake, specify path to llvm-config tool: /usr/lib/llvm-2.9/bin/llvm-config, finally was unable to build from sources. :(

D programming under MacOS X 10.6, LDC

See http://dsource.org/projects/ldc/wiki/OSXBuildInstructions

Macports to install llvm package (2.9). Then get the latest LDC (tip) from bitbucket mercurial repo, ccmake, adjust paths to match those of MacPorts (/opt/local).

Then build and install tango, as described in the link above.

Edit ldc.conf


switches = [
"-I/opt/local/include/d",
"-I/opt/local/include/d/tango/core/vendor",
"-L-L%%ldcbinarypath%%/../lib",
"-L-ltango",
"-d-version=Tango",
"-defaultlib=tango-ldc",
"-debuglib=tango-ldc"
];

LDC under MacOSX

Can't build it yet but the information I gathered is as follows:

Setup

sudo port install llvm
sudo port install llvm-devel
sudo port install mercurial
sudo port install ruby
sudo port install cmake

hg clone -r 0.9.2 https://bitbucket.org/lindquist/ldc
svn co http://svn.dsource.org/projects/tango/tags/releases/0.99.9 tango

Building LDC

cmake -DCMAKE_BUILD_TYPE=Release -DDEFAULT_TARGET="x86_64-apple-darwin10" ../ldc
make -j2

Genius G-Pen 560 under Ubuntu 10.04

1) add ppa and install wizardpen driver (xorg) from it
2) edit /usr/lib/X11/xorg.conf.d/70-wizardpen.conf to the following:

Section "InputClass"
Identifier "wizardpen"
MatchIsTablet "on"
MatchDevicePath "/dev/input/event*"
# MatchVendor "UC-LOGIC|KYE Systems|Ace Cad"
Driver "wizardpen"
Option "TopZ" "32"
Option "BottomZ" "1023"
Option "TopX" "185"
Option "TopY" "372"
Option "BottomX" "11811"
Option "BottomY" "8793"

EndSection
Section "InputClass"
Identifier "wizardpen ignore mouse dev"
MatchIsTablet "on"
MatchDevicePath "/dev/input/mouse*"
# MatchVendor "UC-LOGIC|KYE Systems|Ace Cad"
Driver ""
EndSection

3) reboot
