Installation

LDC Installation process

This section will explain how install ldc on your system

Build dependencies

• libconfig
• libconfig-devel
• cmake
• gc
• gcc-c++
• gcc
• libconfig
• llvm 3.0

LLVM

On linux many distribution have already packaged this one, so take it.

Manual build

Download llvm 3.0 $ wget http://www.llvm.org/releases/3.0/llvm-3.0.tar.gz

on 32 bit system

$ ./configure --prefix=/usr             \
              --bindir=/usr/bin         \
              --datadir=/usr/share      \
              --includedir=/usr/include \
              --libdir=/usr/lib         \
              --enable-optimized        \
              --enable-assertions

on 64 bit system

$ ./configure --prefix=/usr             \
              --bindir=/usr/bin         \
              --datadir=/usr/share      \
              --includedir=/usr/include \
              --libdir=/usr/lib64       \
              --enable-optimized        \
              --enable-assertions

Build llvm

make -j9

Install llvm

su -c 'make install'

LDC

Now we will build and install ldc as D2 compiler. In first download ldc.

$ git clone git://github.com/ldc-developers/ldc.git

Get druntime and phobos2 for ldc.

$ cd ldc; git submodule init; git submodule update;

Manual build

By default build ldc as D2 compiler

In /usr/local

$ cmake .
$ make -j9 VERBOSE=2 phobos2

In /usr

$ cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr .
$ make -j9 VERBOSE=2 phobos2

In your home dir

$ cmake -DCMAKE_INSTALL_PREFIX:PATH=${HOME} .
$ make -j9 VERBOSE=2 phobos2

Usefull variable

• LIB_SUFFIX some operating system use /usr/lib64 as lib dir for 64bits libraries like Fedora, Ubuntu ...
  In this case -DLIB_SUFFIX=64
• CMAKE_INSTALL_PREFIX this var could be used:
• default prefix is /usr/local
• User install you want install in your home directory so set CHROOT_INSTALL_DIR as ${HOME}
• BUILD_SHARED_LIBS you want build as static library turn to OFF: -DBUILD_SHARED_LIBS=OFF
• INCLUDE_INSTALL_DIR if you want install header file in other directory as default
• D_VERSION this var equal 2 by default set this one to 1 if you want build ldc as D1 compiler
• PHOBOS2_DIR if you have put the phobos dir in other way set path to right dir
• RUNTIME_DIR
• if you have put the runtime dir in other way set path to right dir (D2 => druntime)
• if you build as D1 compiler and use ccmake set this var to runtime dir

Install ldc

$ su -c 'make install'

Tips

Sometime you have a build's computer and an other computer to install. So on on your build's computer by example you mount in /mnt the root dir of install computer. In this cas set DESTDIR as /mnt.

$ su -c 'make install DESTDIR=/mnt'
