libfm-qt is the Qt port of libfm, a library providing components to build desktop file managers which belongs to LXDE.

libfm-qt is licensed under the terms of the LGPLv2.1 or any later version. See file LICENSE for its full text.

Runtime dependencies are Qt X11 Extras and libfm ≥ 1,2 (not all features are provided by libfm-qt yet).
Additional build dependencies are CMake, lxqt-build-tools and optionally Git to pull latest VCS checkouts. The localization files were outsourced to repository lxqt-l10n so the corresponding dependencies are needed, too. Please refer to this repository's README.md for further information.

Code configuration is handled by CMake. CMake variable CMAKE_INSTALL_PREFIX has to be set to /usr on most operating systems, depending on the way library paths are dealt with on 64bit systems variables like CMAKE_INSTALL_LIBDIR may have to be set as well.

To build run make, to install make install which accepts variable DESTDIR as usual.

Official binary packages are available in Arch Linux, Debian (as of Debian stretch) and openSUSE (Leap 42.1 and Tumbleweed).
The library is still missing in Fedora which is providing version 0.10.0 of PCManFM-Qt only so far. This version was still including the code outsourced into libfm-qt later so libfm-qt will have to be provided by Fedora, too, as soon as the distribution upgrades to PCManFM-Qt ≥ 0.10.1.
