Update Makefile variable names 2014-02-01 11:23:14 +00:00			`libraries += libexpr`

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). 2013-11-23 23:53:41 +00:00			`libexpr_NAME = libnixexpr`

Rename $(here) to $(d) for brevity, and remove trailing slash 2013-11-22 16:45:52 +00:00			`libexpr_DIR := $(d)`

Allow (dynamic) libraries to depend on other libraries 2013-11-23 20:11:02 +00:00
Don't try to link libdl on FreeBSD. There is no libdl on FreeBSD. Instead the symbols are included in libc. 2015-10-02 13:35:33 +00:00			`libexpr_LDFLAGS =`
			`ifneq ($(OS), FreeBSD)`
			`libexpr_LDFLAGS += -ldl`
			`endif`
Add importNative primop This can be used to import a dynamic shared object and return an arbitrary value, including new primops. This can be used both to test new primops without having to recompile nix every time, and to build specialized primops that probably don't belong upstream (e.g. a function that calls out to gpg to decrypt a nixops secret as-needed). The imported function should initialize the Value & as needed. A single import can define multiple values by creating an attrset or list, of course. An example initialization function might look like: extern "C" void initialize(nix::EvalState & state, nix::Value & v) { v.type = nix::tPrimOp; v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun")); } Then `builtins.importNative ./example.so "initialize"` will evaluate to the primop defined in the myFun function. 2014-06-01 14:42:56 +00:00
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 20:19:36 +00:00			`# The dependency on libgc must be propagated (i.e. meaning that`
			`# programs/libraries that use libexpr must explicitly pass -lgc),`
			`# because inline functions in libexpr's header files call libgc.`
