The Aalto ASR libraries and tools are built with CMake build system. They build natively in Unix-like operating systems. Building for Windows is possible under MinGW / MSYS environment, or using the gcc-mingw cross-building tools under Unix.

Building under Unix-like operating systems

Required packages for Ubuntu (and other Debian-based distributions)

build-essential
cmake

swig
libsndfile1-dev
libsdl1.2-dev
liblapack-dev
python2.7-dev
gfortran

libfftw3-dev (Optional. If not provided KissFFT is used)

Required packages for Scientific Linux (and other Redhat-based distributions)

yum groupinstall "Development Tools"
cmake28 (EPEL)

SDL-devel
python-devel
lapack-devel
libsndfile-devel

fftw-devel (optional. If not provided KissFFT is used)

Build instructions

git clone https://github.com/aalto-speech/AaltoASR.git
cd AaltoASR
mkdir build
cd build 
cmake ..
make

Instead of make all, also only a subproject or executable can be build, e.g.:

make aku

or make playseg

After this all a

make install

will install the binaries and libraries on the correct places. This location can be changed with the option -DCMAKE_INSTALL_PREFIX=/path to the cmake command.

For a debug build, add -DCMAKE_BUILD_TYPE=Debug to the cmake command (very slow). For an optimized build add -DCMAKE_BUILD_TYPE=Release.

Normally, if available, the FFTW library is used, otherwise the KissFFT library is used. To force the KissFFT library, add -DKISS_FFT=1 to the cmake command.

Creating an Eclipse project

If you would like to edit/debug the source code in Eclipse, you can follow the instructions given on http://www.vtk.org/Wiki/Eclipse_CDT4_Generator

In short

git clone https://github.com/aalto-speech/AaltoASR.git
cd AaltoASR
cmake -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug .

And import the resulting project in Eclipse.

Building under Windows and MinGW

  1. Install MSYS2 environment.

Follow the instructions on this page: http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/

  1. Open MinGW-w64 Win32 Shell and install the build tools and dependencies.

Enter in the MSYS2 prompt:

  pacman -S mingw-w64-i686-gcc
  pacman -S mingw-w64-i686-gcc-fortran
  pacman -S git
  pacman -S make
  pacman -S mingw-w64-i686-cmake-git
  pacman -S mingw-w64-i686-SDL
  pacman -S mingw-w64-i686-libsndfile
  pacman -S mingw-w64-i686-openblas-git
  pacman -S mingw-w64-i686-lapack
  1. Install AaltoASR.

While in the MSYS2 prompt, download AaltoASR. Before building, specify the MinGW resource compiler (windres) in RC environment variable. Otherwise lapackpp may not find it (showing the error "ld.exe: cannot find ressource.o: No such file or directory").

  cd /mingw32
  mkdir src
  cd src
  git clone https://github.com/aalto-speech/AaltoASR.git
  cd AaltoASR
  mkdir build
  cd build
  export RC=windres
  cmake .. -G"MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_PREFIX_PATH=/mingw32 -DCMAKE_INSTALL_PREFIX:PATH=/mingw32 \
    -DDISABLE_SWIG=On -DDISABLE_TOOLS=On
  make
  make install

Common build problems with MinGW and MSYS

  1. Lapackpp configuration fails at "could not determine path for home".

Lapackpp configure command stops at the following error:

  checking for windoze home path (mingw)... configure: error: Could not determine path for home

AaltoASR/build/vendor/lapackpp/src/lapackpp_ext/config.log shows:

  C:/Development/msys32/mingw32/bin/../lib/gcc/i686-w64-mingw32/4.9.2/../../../../i686-w64-mingw32/bin/ld.exe: cannot open output file conftest.exe: Permission denied

This problem occurs often when File System Auto-Protect is enabled from Symantec Endpoint Protection. Disable Auto-Protect, wipe the build directory, and re-run cmake and make.

Creating an Eclipse project

It is possible to create an Eclipse project in Windows, but compilation has to be done from an MSYS shell. Follow the instructions above, but instead of the typical out-of-source build, use the Eclipse CDT4 generator in the source directory:

  cd ${LOCALSOURCEDIR}/AaltoASR && \
  cmake . -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_PREFIX_PATH=${LOCALDESTDIR} -DDISABLE_SWIG=On -DDISABLE_TOOLS=On

and import the project from C:\MinGW\sources\AaltoASR. To compile, run make from the MSYS prompt.

Cross-compiling for Windows under Unix-like operating systems

Required packages for Ubuntu (and other Debian-based distributions)

build-essential
cmake
gcc-mingw-w64-i686 (or gcc-mingw-w64-x86-64)
gfortran-mingw-w64-i686 (or gfortran-mingw-w64-x86-64)

Build instructions

First the dependencies have to be compiled with the cross-compiler. You want to install all the cross-compiled software in a separate directory structure. The following examples use /local/i686-w64-mingw32.

wget http://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.gz
tar xf libogg-1.3.2.tar.gz
cd libogg-1.3.2
./configure --prefix=/local/i686-w64-mingw32 --host=i686-w64-mingw32
make
make install
cd ..

wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.4.tar.gz
tar xf libvorbis-1.3.4.tar.gz
cd libvorbis-1.3.4
./configure --prefix=/local/i686-w64-mingw32 --host=i686-w64-mingw32 \
  CFLAGS=-I/local/i686-w64-mingw32/include LDFLAGS=-L/local/i686-w64-mingw32/lib
make
make install
cd ..

wget http://downloads.xiph.org/releases/flac/flac-1.3.1.tar.xz
tar xf flac-1.3.1.tar.xz
./configure --prefix=/local/i686-w64-mingw32 --host=i686-w64-mingw32 \
  CFLAGS=-I/local/i686-w64-mingw32/include LDFLAGS=-L/local/i686-w64-mingw32/lib
make
make install
cd ..

wget http://www.mega-nerd.com/libsndfile/files/libsndfile-1.0.25.tar.gz
tar xf libsndfile-1.0.25.tar.gz
cd libsndfile-1.0.25
./configure --prefix=/local/i686-w64-mingw32 --host=i686-w64-mingw32 \
  --disable-sqlite --disable-alsa \
  CFLAGS=-I/local/i686-w64-mingw32/include LDFLAGS=-L/local/i686-w64-mingw32/lib
make
make install
cd ..

git clone https://github.com/xianyi/OpenBLAS.git
cd OpenBLAS
make BINARY=32 CC=i686-w64-mingw32-gcc FC=i686-w64-mingw32-gfortran HOSTCC=gcc TARGET=CORE2
make install PREFIX=/local/i686-w64-mingw32
cd ..

Then build AaltoASR using the cross-compilation toolchain.

git clone https://github.com/aalto-speech/AaltoASR.git
cd AaltoASR
mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=cmake/cross-mingw-i686/toolchain.cmake -DCMAKE_BUILD_TYPE=Release \
  -DDISABLE_SWIG=On -DDISABLE_TOOLS=On \
  -DCMAKE_PREFIX_PATH=/local/i686-w64-mingw32 -DCMAKE_INSTALL_PREFIX:PATH=/local/i686-w64-mingw32
make
make install
