Hunspell.dll ksztse / create (Forrs / source : https://delphihaven.wordpress.com/2010/02/06/compiling-a-hunspell-dll-step-by-step): 

1.
Make sure you have a suitable C++ compiler at the ready. Ive no idea about C++Builder, but Visual C++ Express does the job fine, and its free.

2.
Make sure you have something like the (open source) 7-ZIP installed so you can open a compressed tarball file (.tar.gz).

3.
Download the Hunspell source from Hunspells Sourceforge homepage.

4.
Extract said source to a suitable directory. If you inspect the extracted files, youll come across more than one MSVC project file  specifically, you should be able to find one for MSVC 6 in src\hunspell (hunspell.dsp) and a MSVC 2005 project group (solution) in src\win_api (Hunspell.sln, hunspell.vcproj, libhunspell.vcproj, testparser.vcproj). Basically, Hunspell is a C++ library, though at some point, a new DLL project file with C exports (the one in win_api) was added to the standard distribution to make using Hunspell with (e.g.) Delphi simpler. Later still however, a C interface with slightly different signatures was added to the main source. Consequently, it doesnt really matter which project file you choose  my wrapper supports DLLs produced by either. Also, while only the win_api project file is set to create a DLL by default, youll still have to fiddle about with it before getting it to compile, and once done, it will create a slightly larger DLL compared to the other one.

5.
That in mind, load up MSVC Express, go to File|Open|Project/Solution, and find your way to src\hunspell\hunspell.dsp.  Accept the resulting prompt to convert the project file to the newest format.

6.
Go to Project|Add Existing Item, and from src\hunspell, choose every .cxx and .hxx file. I also suggest adding Hunspell.rc from src\win_api too.

7.
Go to Project|Properties, select Configuration Properties in the tree view, then All Configurations in the Configurations combo box (the latter lies directly above the tree view). Next, change Configuration Type to Dynamic Library (.dll), before selecting  C/C++ in the tree view and setting Additional Include Directories to ..\win_api.

8.
You should now be able to build the project, which will produce hunspell.dll under src\hunspell\Debug. To create a release build, select the Release configuration (most easily from the combo box immediately to the right of the run toolbar button), and rebuild. This should cause another hunspell.dll to be created, only this time under src\hunspell\Release.
