Building GrandOrgue from sources

Obtaining the source code

With git

The simplest way of getting source codes is to use git.

  1. Go to some directory where the GrandOgue source subdirectory will be created

  2. Clone the main GrandOrgue repository

    git clone --recurse-submodules https://github.com/GrandOrgue/grandorgue.git

The source code will be fetched in the GrandOrgue subdirectory of the current directory

Manually

You can download the source code archive from GitHub

  1. Download archive

    • For getting the last sources from master branch go to the Download ZIP on GitHub
    • For getting sourcecode of a certain GrandOrgue release go to the Releases page, select the particular release, scroll down to Assets and download the Source code (zip) or Source code (tar.gz)

  2. Unpack this archive to some directory

  3. Download external submodules

    1. RtAudio: Download the source archive end extract it's contents to the submodules/RtAudio subdirectory of GrandOrgue source tree.
    2. RtMidi: Download the source archive and extract it's contents to the submodules/RtMidi subdirectory of GrandOrgue source tree.

Building for Linux on Linux

  1. Make sure that GrandOrgue source tree has been extracted to some subdirectory <GO source tree>
  2. Install requires software
    • Manually
      1. Install gcc C++ compiler, make, cmake and the development packages of wxWigets, jack (libjack), pkg-config, fftw (fftw3), wavpack and alsa (libasound) from your distribution
      2. Install docbook-xsl, xsltproc, zip, gettext and po4a (if present on your distribution)
    • Or run the prepared scripts for certain linux distributions by a sudoer user:
      • on Fedora run <GO source tree>/build-scripts/for-linux/prepare-fedora.sh
      • on OpenSuse run <GO source tree>/build-scripts/for-linux/prepare-opensuse.sh
      • on Debian 9+ or on Ubuntu 18+ run <GO source tree>/build-scripts/for-linux/prepare-debian-ubuntu.sh
  3. Build

    • Manually

      1. Create an empty build directory, eg:

        mkdir $HOME/gobuild

      2. Run cmake

        cd /home/user/gobuild
cmake -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" <GO source tree>

        Hint: For debugging a build, add the -DCMAKE_CXX_FLAGS=-g -DCMAKE_C_FLAGS=-g option to cmake.

      3. Run make

        make

      4. For making tar.gz, rpm and deb packages, run

        make package

      5. For making rpm source package, run

        cpack -G RPM --config ./CPackSourceConfig.cmake

    • Or run the prepared build script

      <GO source tree>/build-scripts/for-linux/build-on-linux.sh

      The built packages will appear in the build-for/linux subdirectory of current directory, the executables - in build-for/linux/bin

Building for OS X on OS X

  1. Prequisites:

    1. OS X >= 10.11
    2. Xcode >= 7.3
    3. homebrew

  2. Extract the GO sources somewhere, eg: /home/user/gosources

  3. Install the required software

    • Manually

      brew update
brew install gettext jack docbook-xsl wxmac cmake pkg-config fftw wavpack
brew link gettext --force

    • Or run the prepared scripts by a sudoer user:

      <GO source tree>/build-scripts/for-osx/prepare-osx.sh

  4. Build

    • Manually

      1. Create an empty build directory, eg: mkdir /home/user/gobuild

      2. Run cmake:

        cd /home/user/gobuild
cmake -G "Unix Makefiles" -DDOCBOOK_DIR=/usr/local/opt/docbook-xsl/docbook-xsl <GO source tree>

        Hint: For debugging a build, add the -DCMAKE_CXX_FLAGS=-g -DCMAKE_C_FLAGS=-g option to cmake.

      3. Run make

        make

      4. For making tar.gz package, run

        make -k package VERBOSE=1

    • Or run the prepared build script

      <GO source tree>/build-scripts/for-osx/build-on-osx.sh

      The built package will appear in the build-for/osx subdirectory of current directory,

Cross-building for Windows-64 bit on Linux

  1. Install mingw-w64 (On Debian/Ubuntu, install the package mingw-w64) and all packages needed to build GO under Linux.

  2. Prepare 5 directores:

    1. extracted wxWidgets sources [use the lastest release] to a directory (/wxsrc)
    2. extract GO trunk sources to a directory (/gosrc)
    3. create empty install directory (/inst)
    4. create empty win build directory (/buildwin)
    5. create empty linux build directory (/buildlinux)

    In the following, I use the short path from above - normally you would put them somewhere under $HOME and use something like /home/user/GO/wxsrc.

  3. Build wxWidgets

    cd /wxsrc
./configure --host=i686-w64-mingw32 --prefix=/inst --enable-unicode
git apply /gosrc/wxWidgets/wxWidgets-fix-build-3.0.2.patch
(cd locale && make allmo)
make
make install

  4. Build the tools for linux

    cd /buildlinux
cmake -G "Unix Makefiles" /gosrc/src/build
make

  5. Create toolchain definition for windows, file /inst/toolchain.def:

    # the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)
SET(MSYS 1)

 # which compilers to use for C and C++
SET(CMAKE_C_COMPILER i686-w64-mingw32-gcc)
SET(CMAKE_CXX_COMPILER i686-w64-mingw32-g++)
SET(CMAKE_RC_COMPILER i686-w64-mingw32-windres)
SET(PKG_CONFIG_EXECUTABLE i686-w64-mingw32-pkg-config)

 # here is the target environment located
SET(CMAKE_FIND_ROOT_PATH  /usr/i686-w64-mingw32 /inst)

 # adjust the default behaviour of the FIND_XXX() commands:
 # search headers and libraries in the target environment, search 
 # programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

  6. Build GO for windows

    cd /buildwin
cmake -DCMAKE_TOOLCHAIN_FILE=/inst/toolchain.def /gosrc -DCMAKE_INSTALL_PREFIX=/inst -DSTATIC=1 -DIMPORT_EXECUTABLES=/buildlinux/ImportExecutables.cmake -DRTAUDIO_USE_ASIO=OFF
make

    -DRTAUDIO_USE_ASIO=OFF turns building ASIO off - else you need to put the ASIO SDK into the sources

  7. If you have installed NSIS too, run

    make package

    to create an installer

  • If you want to build a 64bit version, replace everywhere in this instruction i686-w64-mingw32 with x86_64-w64-mingw32.

Simplified cross-compiling for Windows on Linux

There are some ready-to use bash scripts that allow to build windows executables on linux. Assume you have the GrandOrgue source extracted to GrandOrgue directory

  1. Install the necessary software running a prepare-script by root or a sudoer-user

    • If you have OpenSuse, run

      GrandOrgue/build-scripts/for-win64/prepare-opensuse.sh

    • If you have Ubuntu 20.04+, run GrandOrgue/build-scripts/for-win64/prepare-ubuntu-20.sh

  2. run build:

    GrandOrgue/build-scripts/for-win64/build-on-linux.sh

    Windows executables will appear in the build-for/win64 subdirectory of the current directory
