Thanks for pointing this : Sorry, the next time I will do.

Thanks also for running and improving MacPorts.

Looks like the compiler blacklist needs some tweaking, to prevent it picking

:info:configure -- The CXX compiler identification is AppleClang 7.0.2.7000181
:info:configure -- The C compiler identification is AppleClang 7.0.2.7000181
:info:configure -- Check for working CXX compiler: /usr/bin/c++

opencv: add compiler blacklist

Are you sure you updated properly ? your build is still using /usr/bin/c++ which should have been explicitly blacklisted in the above commit.

[kencu (Ken)]

It probably goes to /usr/bin/cc because it doesn't have anything on the fallback list that is not blacklisted to choose.

:warn:configure All compilers are either blacklisted or unavailable; defaulting to first fallback option
:debug:configure Environment: 
:debug:configure CC='/usr/bin/cc'

[cjones051073 (Chris Jones)]

In my case with my 10.10 VM it picks macports 5.0. I don't see why this would behave differently...

[cjones051073 (Chris Jones)]

Also, I thought macports clang 5.0 was always in the fallback list by default. It shouldn't need explicitly adding no ?

[cjones051073 (Chris Jones)]

This is what I see

Above preferred compiler list is what I would expect to see. This is a box standard install of Macports in a 10.10 VM, I have not teased anything... I have to assumed the OP has tweaked something to change this in their case...

macdeport - Please run

sudo port clean opencv
sudo port -d configure opencv 2>&1 | tee configure.log

and post what you get.

[cjones051073 (Chris Jones)]

Also note, whilst I cannot point you to a log the build also worked fine in the build bots

​http://packages.macports.org/opencv/

binaries exist down to mac OS 10.9 (Darwin 13). So clearly the build there also picked a working compiler too...

Incidentally, macdeport - Why are you building from source anyway, rather than using the binary tarballs ? Is this intentional ? Perhaps whatever change to your macports configuration you have done to cause this, is also why the builds do not work for you ....

I am not a MacPorts, nor a Unix, expert : I simply appreciate and survive (well in general)...

If there is anything I can do to improve my configuration, it will be with pleasure, if you guide me. Thank you.

[cjones051073 (Chris Jones)]

A default installation will be using the binary tarballs when available. If your installation is not then there must be some reason. Without more details on what you did when you set up it, I cannot help more.

[cjones051073 (Chris Jones)]

do you get binary tarballs for other ports, or is everything installed from source for you ?

[cjones051073 (Chris Jones)]

You appear to not have Xcode installed. i.e. you have

DEBUG: OS X 10.10 (darwin/14.5.0) arch i386
DEBUG: MacPorts 2.5.4
DEBUG: Xcode none
DEBUG: SDK 10.10
DEBUG: MACOSX_DEPLOYMENT_TARGET: 10.10
Warning: Xcode does not appear to be installed; most ports will likely fail to build.

I have

DEBUG: MacPorts 2.5.4
DEBUG: Xcode 7.0.1
DEBUG: SDK 10.10
DEBUG: MACOSX_DEPLOYMENT_TARGET: 10.10

you should have paid attention to the warning above. Please install Xcode and try again.

Yes in general I get binary tarballs and some time MacPorts update are automatically though compilation

You're absolutely right I didn't install XCode and its GBs that I don't have the use of but only the command tools as indicated in a reference I don't retrieves at time.

In addition, I tried a clean reinstallation of OpenCV:

sudo port clean --all opencv
sudo port uninstall opencv port
sudo port -v install opencv @3.4.7_0+python37
...
Error: Processing of port opencv failed

How to install the compiled version directly?

[cjones051073 (Chris Jones)]

you are using a non default variant (python37). This is why you are not using the binary install tarballs, because these are only available for the default variants of each port.

If you want to use the binary install, remove +python37. Otherwise, I am afraid I am out of ideas as to why building from source is not working for you, sorry.

[cjones051073 (Chris Jones)]

b.t.w. you are correct *some* ports can be built without having Xcode installed. However, as the warning above notes not having it installed is likely to cause problems. If you have happy to live with this, fine, that's up to you. Otherwise just install Xcode.... Your choice.

[macdeport]

At this time there are 608 ports installed here and over several years opencv +python37 is the 1st in this situation: maybe I was especially lucky in this area?

Anyway, thank you for your careful help.
