nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images. nomacs is licensed under the GNU General Public License v3 and available for Windows, Linux, FreeBSD, Mac, and OS/2.
We assume you have an IDE (i.e. Visual Studio), python, git, and Qt installed.
Get all dependencies:
git submodule init
git submodule updateProject folders in 3rd-party will not be empty anymore. Now call:
python scripts/make.py "qtpath/bin"This will build nomacs into build/nomacs. If you are using Visual Studio, you can then double-click build/nomacs/nomacs.sln. Right-click the nomacs project and choose Set as StartUp Project.
Build individual projects using:
python scripts/make.py "qt/bin" --project quazip,libraw --forceI like having a separate developer build (without submodules) that uses 3rd party libs already compiled. To do so you need to:
git submodule update --init --remote scripts
# python scripts/make.py "C:\Qt\Qt-5.14.1-installer\5.14.2\msvc2017_64\bin" --lib-path C:\coding\nomacs\nomacs\3rd-party\build
python scripts/make.py "qt/bin" --lib-path "nomacs/3rd-party/build"- check if you have setup opencv (otherwise uncheck ENABLE_OPENCV)
- check if your Qt is set correctly (otherwise set the path to
qt_install_dir/qtbase/bin/qmake.exe) - check if your builds proceeded correctly

For Ubuntu 21.04 and above:
sudo apt-get install debhelper cdbs qt5-qmake qttools5-dev-tools qtbase5-dev qttools5-dev libqt5svg5-dev qt5-image-formats-plugins libexiv2-dev libraw-dev libopencv-dev cmake libtiff-dev libquazip5-dev libwebp-dev git build-essential lcov libzip-dev -
For older Ubuntu versions:
sudo apt-get install debhelper cdbs qt5-qmake qttools5-dev-tools qt5-default qttools5-dev libqt5svg5-dev qt5-image-formats-plugins libexiv2-dev libraw-dev libopencv-dev cmake libtiff-dev libquazip5-dev libwebp-dev git build-essential lcov libzip-dev
Clone the nomacs repository from GitHub:
git clone https://github.com/nomacs/nomacs.gitThis will by default place the source into ~/nomacs
Go to the nomacs/ImageLounge directory and run cmake to get the Makefiles:
mkdir build
cd build
cmake ../ImageLounge/.Compile nomacs:
makeYou will now have a binary (~/nomacs/build/nomacs), which you can test (or use directly). To install it to /usr/local/bin, use:
sudo make installnote that you have to execute
sudo ldconfigafter a successful install.
Install the heif plugin for HEIF support.
- Set
ENABLE_TRANSLATIONStotrue(default:false) - Build all officially supported plugins
Install Homebrew for easier installation of dependencies. Install required dependencies:
brew install qt5 exiv2 opencv libraw quazip cmake pkg-configClone the nomacs repository from GitHub:
git clone https://github.com/nomacs/nomacs.gitGo to the nomacs directory and run cmake to get the Makefiles:
cd nomacs
mkdir build
cd buildFor Homebrew on Intel models:
Qt5_DIR=/usr/local/opt/qt5/ cmake -DQT_QMAKE_EXECUTABLE=/usr/local/opt/qt5/bin/qmake ../ImageLounge/.For Homebrew on Apple Silicon models:
Qt5_DIR=/opt/homebrew/opt/qt5/ cmake -DQT_QMAKE_EXECUTABLE=/opt/homebrew/opt/qt5/bin/qmake ../ImageLounge/.Run make:
makeYou will now have a binary (nomacs.app), which you can test (or use directly). To install it to /usr/local/bin, use
sudo make installWe have created a docker image that best simulates the travis system (currently it's ubuntu xenial 16.04). To build nomacs in a docker, you have to create the image:
docker build --rm -f "Dockerfile" -t nomacs:latest empty-docker-dirTo deploy nomacs in a docker on your system, you can mount this directory using:
docker run --rm -it -v C:\\coding\\nomacs:/usr/nomacs nomacs:latestIf needed, you can upload the image:
docker login
docker tag nomacs diemmarkus/nomacs
docker push diemmarkus/nomacs:latest
