build failure: DISPATCH_QUEUE_OVERCOMMIT

Drew_Crawford1 · February 26, 2016, 3:06pm

Not sure where to post this, but I'm having trouble building CoreFoundation in swift-DEVELOPMENT-SNAPSHOT-2016-02-25-due to some kind of libdispatch issue.

The exact error is

Hi Drew,

I suspect you are getting caught in some work-in-progress to enable
CoreFoundation for using libdispatch on Linux. If both --foundation and
--libdispatch are given to the invocation of build-script (or are in the
same preset), then the build attempts to build CoreFoundation with
libdispatch dependent functionality enabled. Right now, this doesn't
compile, so the build fails.

As a workaround, in swift-corelibs-foundation/build.py around line 66
disable this block:

if "LIBDISPATCH_SOURCE_DIR" in Configuration.current.variables:
        foundation.CFLAGS += " "+" ".join([
                '-DDEPLOYMENT_ENABLE_LIBDISPATCH',
                '-I'+Configuration.current.variables[
"LIBDISPATCH_SOURCE_DIR"],
                '-I'+Configuration.current.variables[
"LIBDISPATCH_BUILD_DIR"]+'/tests' # for include of dispatch/private.h in
CF
        ])

Sorry this caught you; it has taken longer to get this done than
expected. Blocked on
Add support for CFRunLoop integration APIs by seabaylea · Pull Request #46 · apple/swift-corelibs-libdispatch · GitHub and likely
some follow up changes on both the foundation and dispatch side.

That was it! Thanks for a quick correct answer!

For anyone else in this situation, I have rolled up a patch which can be applied with `git am` as a workaround.

foundation-fix.patch (1.3 KB)

It would probably be simplest to disable it until it is really ready.

I hadn't really thought anyone would be trying to build dispatch and
foundation together who wasn't working on fixing it. Just commenting out
that block in build.py would do it.
