Dispatch is a separate project. There isn’t a dependency in the Dispatch project to tell it is building with a new compiler. The project would need to be modified to add a dependency on the swiftc binary being used to compile this project.

I don’t know how these dependencies are expressed in CMake but it doesn’t seem very difficult to do so in the autotools buildsystem, we have

AC_ARG_WITH([swift-toolchain],
  [AS_HELP_STRING([--with-swift-toolchain], [Specify path to Swift toolchain])],
  [swift_toolchain_path=${withval}
   AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
   SWIFTC="$swift_toolchain_path/bin/swiftc”

in configure.ac which ends up as a SWIFTC makefile variable, so as long as that argument is passed as an absolute path, it should work as a dependency in the build rules

$(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
       $(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES) -primary-file $< \

Is there a JIRA ticket for this ? the IBM folks should probably be the ones making these changes since we still don’t have the whitelist in place for Apple contributors to do so…

I don’t know how these dependencies are expressed in CMake but it doesn’t seem very difficult to do so in the autotools buildsystem, we have

AC_ARG_WITH([swift-toolchain],
[AS_HELP_STRING([--with-swift-toolchain], [Specify path to Swift toolchain])],
[swift_toolchain_path=${withval}
AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
SWIFTC="$swift_toolchain_path/bin/swiftc”

in configure.ac which ends up as a SWIFTC makefile variable, so as long as that argument is passed as an absolute path, it should work as a dependency in the build rules

$(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
$(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES) -primary-file $< \

Is there a JIRA ticket for this ? the IBM folks should probably be the ones making these changes since we still don’t have the whitelist in place for Apple contributors to do so…

I think the right order to build things is:

1. libdispatch (C)
2. Swift (compiler + stdlib + Dispatch overlay)
3. Foundation

Otherwise we need to build Swift, then build libdispatch, then go back to "Swift" to build the overlay, and only finally get to Foundation.

The order may need to vary by platform. On Linux, the DIspatch Swift
overlay code lives in swift-corelibs-libdispatch/src/swift. So it works to
build (1) Swift (2) libdispatch (both C and Swift) (3) Foundation.

The order may need to vary by platform. On Linux, the DIspatch Swift overlay code lives in swift-corelibs-libdispatch/src/swift. So it works to build (1) Swift (2) libdispatch (both C and Swift) (3) Foundation.

Question. Maybe the right thing to do is move the overlay even on OS X into swift. (Just trying to ask obvious questions).

I think the right order to build things is:

1. libdispatch (C)
2. Swift (compiler + stdlib + Dispatch overlay)
3. Foundation

Otherwise we need to build Swift, then build libdispatch, then go back to "Swift" to build the overlay, and only finally get to Foundation.

I don’t know how these dependencies are expressed in CMake but it doesn’t seem very difficult to do so in the autotools buildsystem, we have

AC_ARG_WITH([swift-toolchain],
[AS_HELP_STRING([--with-swift-toolchain], [Specify path to Swift toolchain])],
[swift_toolchain_path=${withval}
AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
SWIFTC="$swift_toolchain_path/bin/swiftc”

in configure.ac which ends up as a SWIFTC makefile variable, so as long as that argument is passed as an absolute path, it should work as a dependency in the build rules

$(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
$(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES) -primary-file $< \

Is there a JIRA ticket for this ? the IBM folks should probably be the ones making these changes since we still don’t have the whitelist in place for Apple contributors to do so…

Oh, I didn’t realize we had a separate copy of the overlay code (almost certainly the right thing to do at this point). But in that case, why are we seeing any of these errors?

When I was working this summer on getting SourceKit to build on Linux, one
challenge I encountered with getting the build to work cleanly was that
SourceKit is in the Swift repo, but it has a dependency on libdispatch.
Moving the dispatch overlay code such that libdispatch could always be
built before Swift would solve that problem nicely as well.

We think that the libdispatch incremental rebuilds didn't know that if
swiftc changed it needed to invalidate the compilation of the swift
dispatch overlay files (missing dependency in the make rule). A localized
change that could be enough to fix the problem is libdispatch PR #178. If
that isn't enough, we might have to do a more ambitious restructuring of
the libdispatch build.

Oh, I didn’t realize we had a separate copy of the overlay code (almost
certainly the right thing to do at this point). But in that case, why are
we seeing any of these errors?

      I think the right order to build things is:

      1. libdispatch (C)
      2. Swift (compiler + stdlib + Dispatch overlay)
      3. Foundation

      Otherwise we need to build Swift, then build libdispatch, then go
      back to "Swift" to build the overlay, and only finally get to
      Foundation.

                  I don’t know how these dependencies are expressed in
                  CMake but it doesn’t seem very difficult to do so in the
                  autotools buildsystem, we have

                  AC_ARG_WITH([swift-toolchain],
                  [AS_HELP_STRING([--with-swift-toolchain], [Specify path
                  to Swift toolchain])],
                  [swift_toolchain_path=${withval}
                  AC_DEFINE(HAVE_SWIFT, 1, [Define if building for Swift])
                  SWIFTC="$swift_toolchain_path/bin/swiftc”

                  in configure.ac which ends up as a SWIFTC makefile
                  variable, so as long as that argument is passed as an
                  absolute path, it should work as a dependency in the
                  build rules

                  $(abs_builddir)/swift/%.o: $(abs_srcdir)/swift/%.swift
                  $(SWIFTC) -frontend -c $(SWIFT_ABS_SRC_FILES)
                  -primary-file $< \

                  Is there a JIRA ticket for this ? the IBM folks should
                  probably be the ones making these changes since we still
                  don’t have the whitelist in place for Apple contributors
                  to do so…

this may be an unintended consequence of us putting the Linux overlay into the library repo (as opposed to the compiler repo).

I still think that is the right place for the overlay to live though, and that we should move the Darwin overlay there as well medium term (and work out any resulting build issues).

On both platforms we want to move towards a more integrated support for the Swift 3 interfaces directly from the library instead of the large overlay we have now.

The problem with moving the Darwin Dispatch overlay there is that other overlays depend on Dispatch, and we’re not ready to move those out somewhere else. That would compound this cross-repo dependency problem.
