Whenever we create scripts that are installed to $out, we must use runtimeShell in order to get the shell that can be executed on the machine we create the package for. This is relevant for cross-compiling. The only use case for stdenv.shell are scripts that are executed as part of the build system. Usages in checkPhase are borderline however to decrease the likelyhood of people copying the wrong examples, I decided to use runtimeShell as well.

/*
|
|
Note that this version of the extension still has some nix specific issues
|
|
which could not be fixed merely by patching (inside a C# dll).
|
|
|
|
In particular, the debugger requires either gnome-terminal or xterm. However
|
|
instead of looking for the terminal executable in `PATH`, for any linux platform
|
|
the dll uses an hardcoded path to one of these.
|
|
|
|
So, in order for debugging to work properly, you merely need to create symlinks
|
|
to one of these terminals at the appropriate location.
|
|
|
|
The good news is the the utility library is open source and with some effort
|
|
we could build a patched version ourselves. See:
|
|
|
|
<https://github.com/Microsoft/MIEngine/blob/2885386dc7f35e0f1e44827269341e786361f28e/src/MICore/TerminalLauncher.cs#L156>
|
|
|
|
Also, the extension should eventually no longer require an external terminal. See:
|
|
|
|
<https://github.com/Microsoft/vscode-cpptools/issues/35>
|
|
|
|
Once the symbolic link temporary solution taken, everything shoud run smootly.
