Build Collabora Office

Linux

Build

Use a separate “online” checkout — not the one you use for regular Online builds. Clone the LibreOffice core repository and switch to the coda-25.04 branch. For general build guidance, see the normal build instruction.

It Requires what Collabora Online already requires and the additionally following Qt libraries: Qt6Core Qt6Widgets Qt6Gui Qt6WebEngineCore Qt6WebChannel Qt6WebEngineWidgets.

Run ./autogen.sh, then configure

./configure --enable-qtapp --with-lo-path=/path/to/core/instdir --with-lokit-path=/path/to/core/include --enable-debug CXXFLAGS="-O2 -g -fPIC"

Adjust the paths to --with-lo-path and --with-lokit-path.

Then run make -j$(nproc) on the top directory. This will result in coda-qt executable in this directory.

Run

Usage: ./qt/coda-qt DOCUMENT [DOCUMENT...]

e.g. ./coda-qt ../test/data/hello.odt

Debug with Chromium DevTools

export QTWEBENGINE_REMOTE_DEBUGGING=3311

Then run coda-qt and open http://localhost:3311

Flatpak

Building flatpak

There is a flatpak manifest under flatpak/com.collabora.Office.json.

Install following dependencies for building the flatpak.

flatpak install org.kde.Sdk//6.9 \
                org.kde.Platform//6.9 \
                org.freedesktop.Sdk.Extension.node20//24.08 \
                org.freedesktop.Sdk.Extension.openjdk21//24.08 \
                io.qt.qtwebengine.BaseApp//6.9

Use flatpak-builder to create a flatpak.

• Build and install user level: flatpak-builder build-dir com.collabora.Office.json --install --user --force-clean --ccache

• Create a bundle from the build-dir: flatpak build-bundle .flatpak-builder/cache CODA-Q.bundle com.collabora.Office
