EUMETCastView

A viewer for the Eumetcast transmissions,EUMETSAT’s primary dissemination mechanism for the near real-time delivery of satellite images.

The Open Source program EUMETCastView allows you to view

• AVHRR images from Metop-A, Metop-B and Metop-C.
• VIIRS images from SUOMI NPP, NOAA-20 and NOAA-21 (M-Band and Day/Night Band)
• VII/METimage from Metop SGA1
• OLCI EFR/ERR from Sentinel-3A
• HRIT/LRIT images from Meteosat-11, Meteosat-10, Meteosat-9, Electro L3, FengYun 2H/2G, GOES-18, GOES-19 and Himawari-9.
• MERSI images from FY-3D
• FCI images from Meteosat-12

Linux software drivers ( for VM's ) : see https://itsfoss.com/install-mesa-ubuntu/

Compile in Linux :

• sudo apt install build-essential cmake
  qt6-base-dev qt6-5compat-dev
  libhdf5-dev libnetcdf-dev libarchive-dev libfreeimage-dev
  mesa-common-dev libglu1-mesa-dev libfontconfig1
• mkdir build
• cd build
• cmake ..
• cmake --build .

Building the AppImage :

Both variants are scripted; don't build them by hand in build/.

• ./scripts/build-appimage-container.sh — the release AppImage. Builds inside an Ubuntu 20.04 container (glibc 2.31, libstdc++ 3.4.28) so it also runs on distributions older than this one, in build-appimage-ubuntu2004/ and AppDir-ubuntu2004/. Needs podman or docker, Qt in ~/Qt/6.9.2/gcc_64, and linuxdeploy, linuxdeploy-plugin-qt and appimagetool in ~/AppImages. When it finishes it reports the symbol floor of everything in the AppDir and whether OpenSSL 3 was bundled.
• ./scripts/build-appimage.sh — the same build natively, in build-appimage/ and AppDir/. Quick to check, but the result only runs on systems as new as this one.

Both write EUMETCastView-x86_64.AppImage in the repository root; rename it for a release. Pass --skip-build to package the binaries already in bin/ instead of rebuilding.

Both also link into bin/, which every build tree shares — after a container build bin/EUMETCastView is the Ubuntu 20.04 binary, so rebuild natively before running or debugging it here.

Compile in Windows :

• Install msys2
• mkdir build
• cd build
• cmake -G "MSYS Makefiles" ..
• cmake --build .

or

Compile in QtCreator (Windows):

Setting up QtCreator

1. Open the "Build & Run" panel in QtCreator options
2. In the "Qt Versions" tab, add a new one pointing to (MSYS2_PATH)/ucrt64/bin/qmake.exe
3. In the "Compilers" tab, add a new one for MinGW C and C++, respectively pointing to (MSYS2_PATH)/ucrt64/bin/gcc.exe and .../g++.exe
4. In the "Debuggers" tab, add a new one pointing to (MSYS2_PATH)/ucrt64/bin/gdb.exe
5. In the "CMake" tab, add a new one pointing to (MSYS2_PATH)/ucrt64/bin/cmake.exe
6. In the "Kits" tab, add a new one where you use the compilers, debugger, qt and cmake defined above
7. Select "CodeBlocks - Ninja" as CMake Generator
