Hii , @SGaist i am using Qt version 5.12.8

Also this is wrong - Qt has no functiondec, but std has: std::decQt Online Installer direct download: https://download.qt.io/official_releases/online_installers/

Then the include for QTextStream is missing. :)

@Christian-Ehrlicher
Just saw it suggest it under
qmuparserbase.cpp:1891:21: note: suggested alternatives:
/usr/include/x86_64-linux-gnu/qt5/QtCore/qtextstream.h:238:28: note: ‘dec’
238 | Q_CORE_EXPORT QTextStream &dec(QTextStream &s);So yeah it could be that simple :)

Hi , Not Solved yet
how to build on 5.12.8 distribution provided
how to install required development packages
how to use full path to the qmake executable.how to build on 5.12.8 distribution provided
You have not told us who provided the distribution
how to install required development packages
That depends on the distribution.
For Ubuntu 20.04 you can see the development packages here.how to use full path to the qmake executable.
$ locate qmake # Select one of the paths to a qmake executable that is shown on your system # Use that # Examples: $ /usr/bin/qmake $ /home/rajel052/Qt/.../bin/qmake -

What is this?! You are supposed to call qmake using absolute path instead of just qmake:
/home/rajel052/Qt/5.15.2/gcc_64/bin/qmake PATH_TO_YOUR_PRO_FILEAlso, delete the content of your build folder before calling qmake.
