It shouldn’t be difficult, if only... While adding support for SmartOS I’ve encountered many “autoconf” packages that claim to be shell agnostic, yet are riddled with BASH-isms. SmartOS comes with KSH installed in /bin/sh by default, that’s how I noticed.
In order to make some progress and not have to patch pretty much every package, I ended up forcibly replacing the #!/bin/sh shebang on every script before buidling: https://github.com/vizanto/nixpkgs/commit/152344c19aa1f8839fc3360eef826d803901a2f8 Best regards, Danny On 1 apr. 2015, at 23:26, Peter Simons <[email protected]> wrote: > Hi guys, > > the default builder in Nixpkgs (and pretty much all other shell code in all > our > packages) assumes that it's interpreted by "bash".
