This section describes how you can build a GNAT-compatible (COFF) object file
containing the resources. You do this using the Resource Compiler
windres as follows:
$ windres -i myres.rc -o myres.o
By default windres runs gcc to preprocess the .rc
file. You can specify an alternate preprocessor (usually named
cpp.exe) using the windres --preprocessor
parameter. You can obtain a list of all possible switches by entering
the command windres --help.
You can also use the Microsoft resource compiler rc.exe
to produce a .res file (binary resource file). See the
corresponding Microsoft documentation for further details. In this case,
you need to use windres to translate the .res file to a
GNAT-compatible object file as follows:
$ windres -i myres.res -o myres.o
