The tools are built by the build GitHub Action.
In addition to the Windows executables (msginit, xgettext, msgfmt, ...), this project also provides development files for MinGW/gcc and Microsoft Visual C (.h, .a, .dll.a, .lib, .dll.lib files).
For example, you have ready-to-use static libraries libasprintf.a, libcharset.a, libgettextpo.a, libiconv.a, libintl.a, libtextstyle.a (for MinGW-w64/gcc) and asprintf.lib, charset.lib, gettextpo.lib, iconv.lib, intl.lib, textstyle.lib (for MSVC) 2-bit and 64-bit systems.
You can download them from the releases page or from the project homepage.
Please refer to the official manuals documentation: here for iconv and here for gettext.
Starting with gettext v0.22.5 / iconv v1.17, the built DLLs and executables are signed.
Free code signing is provided by SignPath.io, certificate by SignPath Foundation.
The source code of gettext and iconv is developed and maintained by the Free Software Foundation.
This gettext-iconv-windows project only compiles gettext and iconv for Windows, and is maintained by Michele Locati.
The gettext and iconv tools do not collect personal data: they are used solely for local work.
