That analogy is the GPL - the concrete (library/APL) is restricting your ownership of your building (App) - you can’t build the building without the concrete, but the restriction for use of concrete forces you to give up your work. Imagine if concrete was a licensed building material and that every time you built a building that used concrete you have to turn ownership of your house over to the manufacturer of the concrete. Here’s an analogy that a member of the FSF team came up with back in the early days of the GPL as to why the LGPL was needed:

You should ask them about the source code and remind them that it’s required for their tool to be LGPL. Hi Tim, can you explain that a little more for someone not familiar with legal issues and English language?įirst, if you are using an LGPL library and the creator is not providing the source code, they are already breaking the rules of LGPL.

The word “Lesser” in the title shows that the LGPL does not guarantee the end user’s complete freedom in the use of software it only guarantees the freedom of modification for components licensed under the LGPL, but not for any proprietary De Poo:

The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the MIT License. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The license only requires software under the LGPL be modifiable by end users via source code availability. The license allows developers and companies to use and integrate software released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components.

The GNU Lesser General Public License (LGPL) is a free software license published by the Free Software Foundation (FSF). Wikipedia’s discussion is actually right on for a change: For example, the C library is LGPL or you wouldn’t be able to create ANY commercial, closed source app for Linux at all. LGPL has the caveat that you can use it in a commercial application without the need to open source the commercial app so long as you include/make available the source code for the library as part of your app. Will be included in next prerelease or if you like to try now, please do not hesitate to contact Winter: The example project lists all the devices and even works nice on Raspberry Pi.

You can open a connection to a device and transfer data as needed.

The new LibUSBDeviceMBS class provides functions to list devices and query information. The library itself is licensed LGPL, so you can load it in commercial applications, but distribute it as DLL/so/dylib file. With quite a few Linux distributions, it comes preinstalled. The new plugin classes are based on the open source LibUSB library, which works on MacOS, Windows and Linux. Wether this is a scale to weight items, barcode devices, various sensors or just a special label printer, we do provide classes to help you.įor some time now we got HIDAPI classes to replace the older MacHID, LinuxHID and WinHID classes to provide a cross platform interface for USB devices with HID protocol.Īnd now we replace MacUSBConnect and WinUSB classes with our new LibUSB classes. Quite a few Xojo developers use our MBS Xojo USB Plugin to connect to devices, do measurements, exchange data and query information for their applications.
