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`

StorePath: Rewrite in C++ On nix-env -qa -f '<nixpkgs>', this reduces maximum RSS by 20970 KiB and runtime by 0.8%. This is mostly because we're not parsing the hash part as a hash anymore (just validating that it consists of base-32 characters). Also, replace storePathToHash() by StorePath::hashPart(). 2020-06-16 12:16:39 +00:00			`libexpr_LIBS = libutil libstore libfetchers`
Allow (dynamic) libraries to depend on other libraries 2013-11-23 20:11:02 +00:00
Fix memory corruption caused by GC-invisible coroutine stacks Crucially this introduces BoehmGCStackAllocator, but it also adds a bunch of wiring to avoid making libutil depend on bdw-gc. Part of the solutions for #4178, #4200 2020-10-30 19:55:53 +00:00			`libexpr_LDFLAGS = -lboost_context`
Apply OS checks to host platform, not build Previously, the build system used uname(1) output when it wanted to check the operating system it was being built for, which meant that it didn't take into-account cross-compilation when the build and host operating systems were different. To fix this, instead of consulting uname output, we consult the host triple, specifically the third "kernel" part. For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a simple ifeq to test whether we're compiling for that system, but for other platforms, like Darwin, FreeBSD, or Solaris, we have to use a more complicated check to take into account the version numbers at the end of the "kernel"s. I couldn't find a way to just strip these version numbers in GNU Make without shelling out, which would be even more ugly IMO. Because these checks differ between kernels, and the patsubst ones are quite fiddly, I've added variables for each host OS we might want to check to make them easier to reuse. 2021-06-01 07:58:21 +00:00			`ifdef HOST_LINUX`
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 += -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),`
