The latest snapshot build at http://pre.racket-lang.org/
adds an `--embed-dlls` option for `raco setup` for use on Windows. The new flag causes the generated ".exe" file to contain a copy of ".dll" files that would otherwise need to be packaged with the ".exe". If there are no other files needed by the executable --- if the program contains no `define-runtime-path`s for files other than DLLs, and so on --- then an ".exe" with embedded DLLs can run all by itself on another machine. The `--embed-dlls` flag should work for most DLLs, including all of the DLLs in the main Racket distribution, but it won't work for everything. Embedded DLLs are linked using the technique described at https://www.joachim-bauch.de/tutorials/loading-a-dll-from-memory/ and using Joachim Bauch's MemoryModule library. It won't work, for example, with DLLs that use thread-local variables (but many DLLs avoid those, since the system `LoadLibrary` function also didn't work for them prior to Windows Vista). DrRacket's "Create Executables" doesn't yet include an option like `--embed-dlls`, but it will soon. If it works as expected, we'll also make `--embed-dlls` automatic for "Create Executables" for the teaching languages. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
