Use libnix as a prefix for all Nix libraries In particular "libutil" was always a problem because it collides with Glibc's libutil. Even if we install into $(libdir)/nix, the linker sometimes got confused (e.g. if a program links against libstore but not libutil, then ld would report undefined symbols in libstore because it was looking at Glibc's libutil). 2013-11-24 00:53:41 +01:00			`libexpr_NAME = libnixexpr`

Rename $(here) to $(d) for brevity, and remove trailing slash 2013-11-22 17:45:52 +01:00			`libexpr_DIR := $(d)`

Drop the dependency on libgc in libmain Instead, libexpr now depends on libgc. This means commands like nix-store that don't do any evaluation no longer require libgc. 2013-11-23 21:19:36 +01:00			`# The dependency on libgc must be propagated (i.e. meaning that`
