I added --enable-cxx11 to configure and removed the space--as discussed 
elsewhere in this thread--from the path to the Qt5 things. The compiler 
problems have gone away but now there appear to be problems linking Qt. Recall 
that the Qt version that I am attempting to reach is 5.5 downloaded from Qt's 
own web site.

Here is my build script:


#  Create a build directory if one does not already exist.
cd /Applications/Words/LyXOuterFolder/git
mkdir -p build

# Clean out any previous build products but leave the build directory (*).
rm -rf /Applications/Words/LyXOuterFolder/git/build/*
rm -rf /Applications/Words/LyXOuterFolder/git/Contents/

cd /Applications/Words/LyXOuterFolder/git/lyx/

# Move to build directory and run configure that is in lyx directory.
cd /Applications/Words/LyXOuterFolder/git/build/
../lyx/configure \
    --with-version-suffix=-2.X \
    --with-libiconv-prefix=/usr/lib \
    --with-x=no \
    --disable-stdlib-debug \
    --enable-cxx11 \
    --prefix=/Applications/Words/LyXOuterFolder/git \
make install-strip

Here are the last few lines with errors. The linker might have found my Qt4 
installation from MacPorts. I don't know if it is 32-bit or 64-bit or both. 
/opt/local/ is the MacPorts stuff. FWIW the referenced library is here:


  CXXLD    lyx
Undefined symbols for architecture x86_64:

lyx::frontend::GuiWorkArea*&, void>(void (lyx::frontend::GuiWorkArea::*&&&)(),

Attached is my config log. It contains the lines

configure:2902: result: no
