Hi,

Did you re-run configure from a clean state ?

After deleting the Configuration files and configure again, the error resolved. but i am getting another error while building qt src 5.9.7 on Ubuntu 16.04.

• [module declarative make first] Error 2
  Even I have tried to installed the qtdeclarative5-dev and qtdeclarative5-private-dev libraries and build again but give the same errors.

sudo ./configure -prefix $PWD/5.9.7 -release -static -accessibility -qt-zlib -qt-libpng -qt-libjpeg -qt-xcb -qt-pcre -qt-freetype -no-glib -no-cups -no-sql-sqlite -no-opengl -no-egl -no-xinput2 -no-sm -no-icu -nomake examples -nomake tests -skip qtactiveqt -skip qtenginio -skip qtlocation -skip qtmultimedia -skip qtserialport -skip qtquick1 -skip qtquickcontrols -skip qtscript -skip qtsensors -skip qtwebsockets -skip qtxmlpatterns -skip qt3d

First thing, don't use sudo, there's no need for that.

Then I would rather do an out of source build with qtbase only and then go on with the rest.

ther do an out o

Could you please update more in details would be helpful.

@Sukdev Out of source build:

mkdir /home/USER/build
cd /home/USER/build
PATH_TO_QT_SOURCES/qtbase/configure ...
make
make install

Basically, you don't build inside source code directory.

Thanks, it's resolved now with building fresh qt src packages and by removing sudo ...
