The VLC-devel port already uses this patch:

https://trac.macports.org/browser/trunk/dports/multimedia/VLC-devel/files/dispatch_queue_serial.patch

It would be best to keep the VLC and VLC-devel ports as similar as possible, so 
maybe you can use (a copy of) this same patch for VLC.

You would provide a patch file modifying the source code as originally
unpacked. See https://guide.macports.org/chunked/development.patches.html
(and the rest of https://guide.macports.org/chunked/ for more information
on Portfile development). This patch should only be applied on pre-10.7
systems.

The filename it's talking about should be a hint... it's a deliberate
failure, and if that had succeeded then configure would have aborted with a
complaint about your C compiler being broken.

Lots of configure tests fail, because configure checks for include files,
libraries, and functions that may or may not exist on any given OS or
release thereof. If the compiler doesn't error out when it should, then it
can't check what functionality works on your system.

Oh sorry, it's qt5-qtwebengine, not qt5-webengine.

If the directory /opt/local/var/macports does not exist you have a problem with 
your MacPorts installation and should reinstall MacPorts. (You can re-download 
the installer from our web site.) Reinstalling MacPorts will not affect your 
installed ports. However, it seems unlikely that that directory would be 
missing, unless you deliberately deleted it.

According to the earlier parts of the log you showed, nothing was installed 
anywhere.

There are countless reasons why a port might fail to build, including that some 
software simply does not build on one version of OS X when it does build on a 
different version of OS X. However, the specific problem you're quoting does 
not initially sound like one of those kinds of problems.

See below ...

I'm attempting to install py34-pyqt5 on OS X 10.8.5. All seems to be going well 
until it fails on installing qtwebengine. Trying to install just this package 
on its own with the -v flag gives me the following output. Can anyone suggest 
what this is telling me or how to fix it? Thanks. (Xcode 5.5.1)

That message is intended for the developer of the port, and is something that would 
certainly have been resolved before the port was committed. The fact that this happened 
to you suggests something unusual is happening in your case. It's hard to know what, 
because you tried again without cleaning first; that might even be the cause of this

Strangely,  "sudo port clean qt5-webengine" tells me "Port qt5-webengine

You quoted a couple of error lines above, but I would be interested in 
knowing what the ones which follow mean:

Error: Please make sure that this software supports 'make install

VLC fails to build

[listmember]

Hello all,

VLC 2.2.2 fails to build on 10.6.8

the build log gives me in $BUILDDIR/work/vlc-2.2.2/modules/gui/macosx

>> :info:build intf.m:688:91: error: use of undeclared identifier 
>> 'DISPATCH_QUEUE_SERIAL'
>> :info:build informInputChangedQueue = 
>> dispatch_queue_create("org.videolan.vlc.inputChangedQueue", 
>> DISPATCH_QUEUE_SERIAL);

A search for 'DISPATCH_QUEUE_SERIAL' brought me to



which offered a potential solution. 

I am not experienced with the phases in macports build process, so here is my 
question:

How to pass NULL for the second parameter to dispatch_queue_create() ?

P.S.

the config log gives an error, too:
> conftest.c:11:10: fatal error: 'ac_nonexistent.h' file not found
> #include 
>  ^

is this somehow related?

thanks in advance
