Kdenlive/Development/WindowsBuild: Difference between revisions

Latest revision as of 16:00, 23 June 2022

Different efforts are currently being led to make building Kdenlive on Microsoft Windows possible. The most successful one is with Craft, as described in the Building and Distributing Kdenlive on Windows and Mac article

Compiling on Windows using Craft (Recommended method)

Set up Craft as described here. (Choose MinGW as compiler)
Start building kdenlive. You can simply run craft kdenlive. If it fails because of zlib, simply run craft zlib and retry. Note that if you want to compile kdenlive in debug mode, you can do so by running craft --buildtype Debug kdenlive

Compiling on Windows in MSYS2 bash shell

Download MSYS2 (x86_64 preferred) and install this unix-like environment for Windows.
Then download our build script to the directory where you want it to work.
From a mingw64 shell, "cd" to that directory and run the script ("./kdenlive-msys2.sh")
Answer "yes" to package manager questions (pacman) to update build system and download dependencies
Wait for MLT & Kdenlive to build
Run Kdenlive from "/mingw64/bin/kdenlive"

Cross compiling on GNU/Linux using MXE

You should first follow the steps necessary to build Kdenlive on GNU/ Linux.

Getting and configuring MXE

Then, on the level where you cloned the kdenlive repository, you should clone a special version of MXE (M cross environment):

git clone https://github.com/vpinon/mxe.git

Then create a settings.mk file with the following command (copy/paste the whole block)

cat >mxe/settings.mk <<EOF
MXE_TARGETS := x86_64-w64-mingw32.shared.posix
override MXE_PLUGIN_DIRS += plugins/multimedia plugins/kdeframeworks plugins/apps
kdenlive_SOURCE_TREE := $PWD/kdenlive
EOF

Installing MXE dependencies

MXE requires the following dependecies (many of which should already be on your system, since you built the GNU/Linux version):

sudo apt install \
    autoconf \
    automake \
    autopoint \
    bash \
    bison \
    bzip2 \
    flex \
    g++ \
    g++-multilib \
    gettext \
    git \
    gperf \
    intltool \
    libc6-dev-i386 \
    libgdk-pixbuf2.0-dev \
    libltdl-dev \
    libssl-dev \
    libtool-bin \
    libxml-parser-perl \
    make \
    openssl \
    p7zip-full \
    patch \
    perl \
    pkg-config \
    python \
    ruby \
    scons \
    sed \
    unzip \
    wget \
    yasm \
    xz-utils

Building kdenlive with MXE

cd mxe
make kdenlive
make gdb  #for debugging
plugins/apps/deploy_kdenlive.sh

Debugging

In case of crash, look for kdenlive PID in the task manager, start gdb:

gdb

And in gdb:

 (gdb)attach PID

-* If you are using Windows 10, turn on Developper mode, as explained here ([https://docs.microsoft.com/en-us/windows/uwp/get-started/enable-your-device-for-development here]
+* Set up Craft as described [[Guidelines_and_HOWTOs/Build_from_source/Windows|here]]. (Choose MinGW as compiler)
-* Install powerShell. You will find the latest version [https://github.com/PowerShell/PowerShell/releases/ here]. If you have a 64bits system (probable if you have a recent system), choose the "win-x64" version. Otherwise, use the "win-x86" version.
-* Create a Craft directory, and download the script:
-<pre>
-cd C:/
-mkdir Craft
-cd Craft
-curl -o https://invent.kde.org/packaging/craft/-/raw/master/setup/CraftBootstrap.py
-</pre>
-* Now, you can run the installer using <code>python CraftBootstrap.py </code>. It will ask for a compiler, choose Mingw-w64, then an architecture, choose 64bits if you are on a 64 bits system. The craft setup up will take a while.
-* As requested, source the environment by running <code>C:\Craft\craft\craftenv.ps1</code>
-* Make sure that craft is properly installed by running <code>craft -i craft</code>
 * Start building kdenlive. You can simply run <code>craft kdenlive</code>. If it fails because of zlib, simply run <code>craft zlib</code> and retry. Note that if you want to compile kdenlive in debug mode, you can do so by running <code>craft --buildtype Debug kdenlive</code>
