How to build under Linux
The original development of nFITSview is done under Linux, so the easiest and the fastest way to build is under Linux.
- just build in Qt Creator.
- it should be also possible to build using CMake from the command line.
The latest version (3.5) of nFITSview install package for Linux 64-bit (Debian-based) is available for download too. The dependencies for installing are:
libboost-iostreams1.83.0 (>= 1.83.0)
libc6 (>= 2.34)
libgcc-s1 (>= 3.0)
libgomp1 (>= 4.9)
libpng16-16t64 (>= 1.6.2)
libqt6core6t64 (>= 6.6.0)
libqt6gui6 (>= 6.1.2)
libqt6network6 (>= 6.1.2)
libqt6widgets6 (>= 6.1.2)
libstdc++6 (>= 14)
How to build under Windows
Normally there is no need to build under Windows as the install package is provided. Anyway, for building under Windows one would need to download/install/build all the dependencies (boost, zlib, libpng), then fix the corresponding pathes for the libraries in the CMakeLists.txt file and then build the project using Qt Creator.
