make it possible to install both headers and library #457

Closed teto closed 4 years ago

teto commented 4 years ago

Hi,

I am trying to bump the nixos package for luv and one problem I have is that I can't install both the library and headers at the same time (or I hqven't found how) because BUILD_MODULE is used for 2 distinguished actions https://github.com/luvit/luv/blob/f38ae04ce02f856566637d2a52527373a5ed61d9/CMakeLists.txt#L131 https://github.com/luvit/luv/blob/f38ae04ce02f856566637d2a52527373a5ed61d9/CMakeLists.txt#L201 On nixos once a package is installed, its folder becomes readonly so that it doesn't get tampered with so I can't rerun the installer twice. I wish there was an other boolean to install the headers (or always install them).

Sounds reasonable to me.

The recommended way to handle having both headers and libraries is to use a nix multiple output derivation to specify the multiple outputs with the separate parts so that the include files are available as build dependencies and the libraries are a separate runtime dependency to reduce the size of the closure.

@aiverson this looks orthogonal; you can arrange the folders in different outputs but this is to avoid running the nix installer twice.
