do you need this to be a static_library or is source_set ok? (this'll be in
practice a thin archive i think which is functionally similar to a source set,
not really a 'thick' .a)

[Nick Bray (chromium), 2015/02/26 01:16:02]

Done.

+    sources = [
+      "mojo_syscall_internal.h",
+      "mojo_syscall.cc",
+      "monacl_sel_main.cc",
+    ]
+    deps = [
+      rebase_path("mojo/public/c/system", ".", mojo_root),

Note: a little funky, but this seemed cleaner than going full
mojo_sdk_source_set (particularly for the executable, below).

+      # This target makes sure we have all the pre-processor defines needed to
+      # use NaCl's headers.
+      "//native_client/build/config/nacl:nacl_base",
+      "//native_client/src/trusted/desc:nrd_xfer",
+      "//native_client/src/trusted/service_runtime:sel_main_chrome",
+    ]
+  }
+}
+
+# Untrusted code
+if (is_nacl) {
+  executable("irt_mojo") {
+    cflags_c = [ "-std=c99" ]
+    sources = [
+      "irt_entry_mojo.c",
+      "mojo_irt.c",
+      rebase_path("mojo/public/platform/nacl/mojo_irt.h", ".", mojo_root),

it looks like nacl_bindings is always in the same place relative to mojo/public,
so could you use a relative path here? i.e.

../mojo/public/platform/nacl/mojo_irt.h

Done.

+    deps = [

[jamesr, 2015/02/26 00:23:22]

and same here?

../mojo/public/c/system
