Does LGPL allow linking?

Does LGPL allow linking?

No, by default a LGPL program cannot link to a proprietary library. LGPL is basically GPL + an exception allowing proprietary programs to link to it.

Can I use LGPL library in commercial software?

You can use and distribute LGPL libraries on your website and use them in combination with commercial code. The only big restriction is that you must keep the library open source, including any modifications you make to it, and allow your users to obtain the source, licence and copyright information for the library.

What is static linking and dynamic linking?

Static linking is the process of copying all library modules used in the program into the final executable image. In contrast, dynamic linking is the process of loading the external shared libraries into the program and then binds those shared libraries dynamically to the program.

Can I modify LGPL code?

You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library.

What is GCC runtime library exception?

This GCC Runtime Library Exception (“Exception”) is an additional permission under section 7 of the GNU General Public License, version 3 (“GPLv3”). When you use GCC to compile a program, GCC may combine portions of certain GCC header files and runtime libraries with the compiled program.

Should I use GPL or LGPL?

The main difference between the GPL and the LGPL is that the latter allows the work to be linked with (in the case of a library, “used by”) a non-(L)GPLed program, regardless of whether it is licensed under a license of GPL family or other licenses.

What is static library and dynamic library?

Static libraries, while reusable in multiple programs, are locked into a program at compile time. Dynamic, or shared libraries on the other hand, exist as separate files outside of the executable file. In contrast, a dynamic library can be modified without a need to re-compile.

What is linking static library?

In computer science, a static library or statically-linked library is a set of routines, external functions and variables which are resolved in a caller at compile-time and copied into a target application by a compiler, linker, or binder, producing an object file and a stand-alone executable.

Which is better static linking or dynamic linking in the LGPL?

A note on static vs. dynamic linking: The LGPL has different requirements depending on how the library is integrated with the remainder of the program. Generally, dynamic linking of LGPL code is considered best practice, as static linking makes meeting the license requirements more complicated.

Which is the best way to link LGPL code?

Generally, dynamic linking of LGPL code is considered best practice, as static linking makes meeting the license requirements more complicated. While it is possible to comply with LGPL code that is integrated into proprietary code as a statically linked library, it requires more effort.

What do you need to know about LGPL licensing?

If not, what else needs to be done? LGPL’s basic requirement is to separate the LGPL-licensed library and your own product well enough. That should allow users to supply their own version of the library instead of the one you’ve shipped with your software (with the bugs fixed, for instance).

Who is the creator of the LGPL license?

The GNU Lesser General Public License (LGPL) is another member of the GNU license family, along with the GNU GPL v2, the GNU GPL v3, and the GNU AGPL License. Like the others, it was published by the Free Software Foundation as part of Richard Stallman’s GNU Project. And like the others, it’s a copyleft license.
