Build fail on OS X - no matching constructor for initialization of 'const QVector<double>'

Hello,
As written in title, I failed on build on mac OSX.

This is when I run cmake.

Is there something I am missing?
Thanks.

Probably an outdated Qt version. @djKooks are you compiling using MacPorts or Homebrew (or other?)

Please read this bug report: #1633

Things to consider...

I assume you're hitting a non-C++11 constructor error, which should be handled already here with the line ADD_DEFINITIONS(-std=c++0x).

• Is this an older build environment that you've recently pulled code down for which may require deleting CMakeCache.txt or is this a fresh clone/fresh build?
• Can you provide your compiler version using clang --version? Are you running an old SDK or anything special we should know about?
• Which Qt version?
• Where did you get Qt from? Is there a chance you are building on MacPorts or some type of system with a non-C++11 build of Qt?

My macOS 10.10 machine:

clang --version
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin15.4.0
Thread model: posix

@tresf Thank for quick reply! I used Homebrew. I followed instruction on https://github.com/LMMS/lmms/wiki/Compiling-lmms-(Apple).
Please refer the versions I used.

kwangin-ui-MacBook-Pro:~ kwangin$ qmake --version
QMake version 2.01a
Using Qt version 4.8.6 in /opt/local/lib
kwangin-ui-MacBook-Pro:~ kwangin$ clang --version
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin14.5.0
Thread model: posix

Thanks.

@djKooks it appears to be picking up a non-Homebrew version of Qt (Homebrew wouldn't install to /opt, however Qt Creator may have).

Can you try to follow the instructions for Qt5? I think specifying Qt5 will fix it up inadvertently and not mess with whatever the other version is for.

If you don't need the /opt version you may decide to remove it which should also fix the problem however since it's finding Qt4 which we're moving away from, the Qt5 instructions should hit two birds, so to speak.

@tresf Thanks! I'll try and let you know.

Your Qt environment does not enable the constructor. This is why the Clang build for Qt4 was dropped in #3208.

FWIW I just encountered this same error after deleting CMakeCache.txt which apparently caused cmake to be run again but without the same parameters as I provided originally (cmake .. -DCMAKE_INSTALL_PREFIX=../target -DWANT_QT5=True -DCMAKE_BUILD_TYPE=Debug -DWANT_SWH=OFF).

Fortunately I'd just seen this issue and so worked out the cause.

I wonder if there's some way to not have this happen or at least warn about it?

BTW thanks for mentioning using qmake --version to determine which Qt version is being used:

$ qmake --version
QMake version 2.01a
Using Qt version 4.8.6 in /usr/local/Cellar/qt/4.8.6/lib

(Side note: I deleted CMakeCache.txt because I couldn't work out why the new Eq plugin wasn't being built... I eventually realised that it was because I was using make lmms which doesn't rebuild the plugins. Whoops. :) )
