Re: [Qgis-user] Error compiling QGIS 2.18.8: "QStringLiteral was not declared in this scope"

[Hernán De Angelis]

Thanks Jürgen and Larry for your fast responses!

Now I sit here trying to get this to work in my machine. Downloaded the
latest master from GitHub and see that now it can only accept qt5 and py3.
QGIS is moving fast!

Cheers and thanks again!

That is also in recent versions of qca.  So this bug only unfolded on platforms
that had older versions (jessie/trusty) - which initially was a bit puzzling.

Re: [Qgis-user] Error compiling QGIS 2.18.8: "QStringLiteral was not declared in this scope"

[Larry Shaffer]

Hi Hernán,

It looks like someone backported a fix from QGIS 2.99 (upcoming 3.0
release) code branch, where QStringLiteral() is preferred over QString()
because it is available in Qt5, and other reasons. The use of
QStringLiteral in 2.x code bases needs removed (as Jürgen mentioned).

Side note: I have gotten around it for C++ plugin development, where I
wanted to compile the same plugin code for QGIS 2 and 3 while focusing more
on QGIS 3 coding style/standards, by using the following macro:

#ifndef QStringLiteral
// Add define for Qt4
// Source code is assumed to be encoded in UTF-8 (as per Qt5 macro)
//# define QStringLiteral(str) QString::fromUtf8(str, sizeof(str) - 1)
// But... that macro does not appear to work on Linux with GCC,
// Just add QString() stub instead
# define QStringLiteral(str) QString(str)
#endif

This *could* be added to 2.x branches (to guard against this type of
error), but there is the problem that there is no standard base included
header file, e.g. qgis.h and qgsconfig.h are not always included. So, no
clear place to put the macro.
