Here are some C and C++ libraries, DLLs, VCLs, source code, components, modules,application frameworks, class libraries, source code snippets, and the like, that you can usewith your programs without payment of fees and royalties. Note that some libraries (etc)listed here may have certain restrictions about its use and/or distribution. Be sure youread the licence conditions in each package before using them.
A few types of libraries have been moved to their own pages, due to the large number of itemsin those categories. Here are some of the other pages containing free libraries on this site:
Free Edit Controls, Libraries and Source Code
Note: if you are looking for WYSIWYG web editors that you can embed into your web page, you should check theFree Online Web-Based WYSIWYG HTML Editor JavaScriptspage instead.
Check out the 20 best free STL viewer tools for all platforms: Online, Mac, Windows, Linux, Android, and iOS. But it's the best STL editor for those interested in 3D sculpting. While it's great for editing, it lacks the ability to repair STL files and sometimes the finished result is non-manifold, which will require using repairing programs (such as those described in the article). The Most Powerful Data and Build Preparation Software. Materialise Magics is a versatile, industry-leading data preparation and STL editor software for Additive Manufacturing that allows you to convert files to STL, repair errors, edit your design and prepare your build platform.

[Update: this library does not seem to be available any more.]GradC++ ToolBox contains several C++ components dealing with threading, program options,logging, and initialisation of COBRA services. It comes with an administrative guide,programmers' guide and sources. I think the C++ library may be used free of charge fornon-commercial purposes, but I'm not sure. It's best to read the licence yourself.
Stl File Creator
[Update: this library does not seem to be available any more.]This library has functions which you can call from your MSDOS programs to access the long filenames (LFN) API found in Windows 95 and above.It thus makes it easy for you to write long file name (LFN) support. The library contains the POSIX.1 compatible opendir()functions, DOS findfirst() functions, open() functions, fopen() functions, mk/rm/chdir(), remove(), unlink(), rename(), getcwd(), getdcwd(),getcurdir(), fullpath(), lfn2sfn(). As you can see, all the hard work of accessing the API has been done for you - just use theusual familiar functions (whether Unix or DOS). It requires a Borland compiler to compile (which you can get it for free, legally - check out theFree C/C++ Compilers page).
