= Build Instructions using Phobos/Druntime trunk on Linux/OSX/FreeBSD/Solaris =

After LDC for D2 has been build,
we can now set up a working LDC environment.

 * Fetch&Compile Phobos/Druntime:

{{{
cd ldc/
git clone https://github.com/AlexeyProkhin/phobos
git clone https://github.com/AlexeyProkhin/druntime
cmake -DRUNTIME_DIR=./druntime -DPHOBOS2_DIR=./phobos .
make phobos2
}}}

 * Setup target directory for installation (root access required):

{{{
mkdir /opt/ldc2
mkdir /opt/ldc2/bin
mkdir /opt/ldc2/import
mkdir /opt/ldc2/lib
}}}


 * Install the ldc2 binary and phobos/druntime library

{{{
cp bin/ldc2 bin/ldmd2 bin/ldc2.conf /opt/ldc2/bin
cp lib/libdruntime-ldc.a lib/liblphobos2.a /opt/ldc2/lib
cp -r druntime/ phobos/ /opt/ldc2/import
cp -r runtime/import/ldc /opt/ldc2/import
}}}



 * Change the contents of /opt/ldc2/bin/ldc2.conf to:

{{{
default:
{
    switches = [
        "-I%%ldcbinarypath%%/../import",
        "-I%%ldcbinarypath%%/../import/druntime/import",
        "-I%%ldcbinarypath%%/../import/phobos",
        "-L-L%%ldcbinarypath%%/../lib",
        "-defaultlib=lphobos2",
        "-debuglib=lphobos2"
    ];
};
}}}

 * Done! :D

'''Notes:'''

 * "object.d: Error: module object cannot read file 'object.d'"; This error indicates that your ldc2.conf is wrong; you may have a stale ldc2.conf around that is used by ldc2 instead.[[BR]] To check for other ldc2.conf files on your system you can do "find / -iname "ldc2.conf"". Or put a syntax error into ldc2.conf; if ldc2 isn't complaining, it's using a different ldc2.conf file.

 * You can install ldc2 in some other directory, of course, but you need to adjust some paths!

----

'''Playtime'''

 * Create a file called main.d:
{{{
import std.stdio;

void main()
{
   printf("Hello World!\n");
}
}}}

 * Compile it to verify that LDC with Phobos is working:
{{{
export PATH=/opt/ldc2/bin:$PATH
ldc2 main.d
./main
}}}
