============ Check out source code and compile with gcc ==========
1. Set up build environment. Please refer to the section "Check out source code and compile with gcc" in this article.
2. Go to http://www.audiocoding.com/. Download FAAD2 2.7 bootstrapped package.
3. Untar FAAD2 2.7 bootstrapped package and build it with gcc. Optionally, you may install it by doing "sudo make install"
$ tar xzvf faad2-2.7.tar.gz
$ cd faad2-2.7
$ ./configure --with-mp4v2
$ make
4. Edit ~/.buildrc. Add the following lines to it.
SetSDKPath("faad2_include", "/path/to/faad2-2.7/include")
SetSDKPath("faad2_lib", "/path/to/faad2-2.7/libfaad/.libs/libfaad.a")
5. Set BIF branch, target and profile as follow. And then build it by doing "3".
[0] Set BIF branch (hxclient_3_1_0_atlas_restricted)
[1] Set Target(s) (dtdrive)
[2] Set Profile (helix-client-all-defines)
[3] run: build -trelease
...
[13] Help Page (full help in build/doc/index.html)
[Q] Quit
6. Now the source code is checked out and dtdrive is successfully compiled with gcc.
============ compile with icc ==========
Recommend to use icc 11.1.064 or later.
0. Build FAAD2 2.7 with icc.
$ ./configure --with-mp4v2 CC=icc CXX=icpc
$ make

3. Edit the following file, as a workaround of DPD200136428. You may skip this step first and try to compile dtdrive with icc. You are expected to see a few errors about type conversion while compiling the following file. The fix is to add force type casting, which is very simple. After applying the fix, compile it again.
datatype-restricted/rm/video/codec/rv89combo/enc/cinterp4i.cpp
4. Edit ./common/util/mmx_util.c in order to fix a code error. Here is the patch.

5. Edit datatype-restricted/rm/video/codec/rv89combo/disp/ccbridge.h to fix a source code bug.

6. Compile dtdrive with icc.
$ make clean
$ make CC=icc CXX=icpc SUBMAKEFLAGS="CC=icc CXX=icpc"
7. Run dtdrive to decode your audio/video files. Please note, you need to go to the directory of dtdrive executable. In addition, make sure the environment variable LD_LIBRARY_PATH includes the path to Intel compiler dynamic libraries, since dtdrive and its dynamic libraries require Intel compiler libraries.
$ cd release
$ ./dtdrive +u file:///root/media/health.rm
