I came across something else like this. Created a
`dub.settings.json` file in the dub project, but still requires
`dmd`:
```sh
$ dub
Performing "debug" build using dmd for x86_64.
app ~master: building configuration "application"...
Running pre-build commands...
Error: unrecognized switch '-Os'
run `dmd` to print the compiler manual
run `dmd -man` to open browser on manual
dmd failed with exit code 1.
```
*dub.settings.json*:
```js
{
"defaultArchitecture": "x86_64",
"defaultCompiler": "ldc"
}
```

It depends on whether your DMD or LDC installation comes first in your PATH environment variable. Both ship with a `dub` executable that uses their compiler as default. And how do I specify the specific compiler I want? On the command line you can use the `--compiler=dmd` flag. You can't specify this in the dub.json, since your project is supposed to be compiler agnostic.

And how do I specify the specific compiler I want? Following the command line documentation [1], you can use the --compiler option to select which to use. You can make the dub.json do different things depending on the target and/or compiler, but the default works fine regardless if you're doing something simple. https://dub.pm/commandline.html

I managed to do it like this:
```js

"authors": [
"Alexander Zhirov"
],
"description": "MyProgram",
"dflags": [

"preBuildCommands": [
"gcc -Os -c c/*.c -o obj/ip_addresses.o"
],
"sourceFiles": [

}
```

How to do it now - I have already forgotten.

I don't know how to do it using dub, but you could use pragma(lib) in one (or more) of your source files as a workaround: pragma(lib, "m"); pragma(lib, "X11"); pragma(lib, "Xrandr"); T -- MACINTOSH: Most Applications Crash, If Not, The Operating System Hangs
