Trouble in building c++ environment

Hi everyone !

I am currently a developer for the Societé des arts technologiques in Montreal. We working on open-sourced tools used by several artists and I have suggested to use the nix package manager in order to package our software. I am attempting to add Shmdata, Switcher and Scenic to nixpkgs but I have some trouble with the c++ linker (with Switcher).

I have forked Nixpkgs into our own repositories and I have added Shmdata and Switcher. The CMake process works fine but I have trouble during the compilation :

-- Build files have been written to: /build/switcher/build
cmake: enabled parallel building
build flags: -j1 -l1 SHELL=/nix/store/r47p5pzx52m3n34vdgqpk5rvqgm0m24m-bash-4.4-p23/bin/bash

I have found some issues about libcstd++ but I don’t know if it is really an issue in my case.

In order to reproduce my issue, you can use my fork of nixpkgs and then just build switcher nix-build -A switcher.

Thanks :wink:

Looks similar to

Try removing glibc from the buildInputs of the derivation?
