compilation failure on macOS - error linking qt

[maxpietsch]

continuing the discussion from the forum:

The problem is that installation on macOS via default ./configure fails if homebrew's libtiff and or fftw libraries are installed. Using homebrew's recipe works:

brew tap MRtrix3/mrtrix3
brew install mrtrix3

I also note that the configure script is running slightly differently - did you add the -v option yourself, or are the versions being compiled somehow different?

@jdtournier Yes, for the default build I ran:

export LDFLAGS=-v 
./configure

I also tried deployment targets 10.12 and 10.10 without success. Log is here.

export MACOSX_DEPLOYMENT_TARGET=10.12
export QMAKE_MACOSX_DEPLOYMENT_TARGET=10.12
./configure

default PATH:

/Users/mp/mrtrix3/bin:/Users/mp/.pyenv/pyenv/bin:/usr/local/opt/qt5/bin:/usr/local/fsl/bin:/Users/mp/mrtrix3/release/scripts:/Users/mp/mrtrix3/release/bin:/usr/local/bin:/usr/local/opt/coreutils/libexec/gnubin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/Library/TeX/texbin

PATH in homebrew's build environment:

PATH=/usr/local/opt/python/libexec/bin:/usr/local/opt/python/bin:/usr/local/Homebrew/Library/Homebrew/shims/super:/usr/local/opt/pkg-config/bin:/usr/local/opt/qt/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/opt/qt5/bin
...
HOMEBREW_INCLUDE_PATHS=/usr/local/opt/qt/include
HOMEBREW_LIBRARY_PATHS=/usr/local/opt/qt/lib:/usr/local/lib:/System/Library/Frameworks/OpenGL.framework/Versions/Current/Libraries

Here is the full homebrew environment, here the default one. Not sure how those get interpreted but this might be helpfull.

If I use Homebrew's path for the standard installation, ./configure fails as it can not find clang. Removing /usr/local/Homebrew/Library/Homebrew/shims/super brings us back to the linking error.

I think Homebrew's compiler flags are set in /usr/local/Homebrew/Library/Homebrew/shims/super/cc which I've uploaded: here.

Seems this will be resolved once #1090 is merged in - closing.
