Qt 5.8 compile issues with std::chrono

492 Views Asked by At

I am developing a Qt application on Ubuntu 17.04. I was previously using the latest Qt version (Qt 5.12.2) but I had to go back a few versions to Qt 5.8.

I was able to compile with using Qt 5.12 with no issues but with Qt 5.8 I get the following errors all related to std::chrono:

In file included from /opt/Qt5.8.0/5.8/gcc_64/include/QtCore>/qmutex.h:48:0,
                 from /opt/Qt5.8.0/5.8/gcc_64/include/QtCore/QMutex:1,
                 ...

/usr/include/c++/6/chrono:221:6: error: macro "max" requires 2 arguments, but only 1 given
  max()

/usr/include/c++/6/chrono:224:19: error: expected ‘;’ before ‘_Rep’
  static constexpr _Rep
                   ^~~~
etc

Any ideas on how to resolve this issue.

Is this a g++ version or a libstdc++ version issue?

Here is my g++ version:

$ g++ --version
g++ (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406
