File To C Array is a tool that generates a C array from the contents of any file. Such arrays can be used as a way of embedding resource files into an executable binary, gaining access to the resource files without having to use platform-dependent code. The tool requires Nana C++ Library in order to build, but you can download a Windows binary below.
Protip: if the output file that you choose is the same as the input file, it will automatically get renamed like in the screenshot above.

g++ --std=c++17 FileToCArray_main.cpp -lnana -lpng -ljpeg -o FileToCArray
If compiling on Windows you will also need to link to some Windows standard libraries:
g++ --std=c++17 FileToCArray_main.cpp -lnana -lpng -ljpeg -lgdi32 -lcomdlg32 -mwindows -o FileToCArray
To add an icon resource do the following:
windres icon_resource.rc -o icon_resource.o
g++ --std=c++17 FileToCArray_main.cpp icon_resource.o -lnana -lpng -ljpeg -lgdi32 -lcomdlg32 -mwindows -o FileToCArray
