Are such things as string so platform dependent in d or the stuff for the class and interface declarations that they aren't cross platform? I meant the gcc used by the n64 toolchain (libdragon). A string in D is a slice. A pointer + length. This is entirely platform agnostic. A dynamic array, is a slice, backed by the GC. This requires the GC and with that druntime. Which means you cannot append to a slice without druntime. Classes require a ton of infrastructure to work. They are not purely a compilation construct.

Dub's static library target type does not include dependencies or druntime/phobos. Typically static libraries do not combine to produce a bigger static library. But thats what I need and want. Combining of static libraries is not specific to D. Although you're going to need to figure out how to get a list of all the static libraries you want to combine. The actual combination should be pretty standard.

Thank you for the information. Sadly nothing for gdc directly. But how is dub solving my problem? Is the buildstep creating a "fat jar". So instead of compiling multiple .d files with gdc I would only compile the "fat jar" from dub? I think you misunderstood me. `dub` is the D's build system and it "knows" how to call the D compilers, including gdc. When you tell dub to build a static library (equivalent to "fat jar" for D) it will use whatever compiler options are needed to do so... you can run `dub build -v -release --compiler=gdc` to see which compiler options it's using to invoke gdc, and then you can just drop dub if you don't need it (though it's very useful to have).
