When building plasma 5.15, everything goes well until
"plasma-workspace". Then
I get the following:
---------------

---------------
The reason for all the errors is in the first warning: TRUE is not
defined, so
it evaluate to 0. Then the appmenu.cpp file has:
----------
#if HAVE_X11
#include <QX11Info>
#include <xcb/xcb.h>
#endif
[...]
#ifdef HAVE_X11
if (KWindowSystem::isPlatformX11()) {
auto *c = QX11Info::connection();
[...]
----------
The first #if HAVE_X11 evaluates to false, so the header file is not
included.
Then the second #ifdef HAVE_X11 evaluates to true, since HAVE_X11 _is_
defined, so that "auto *c = QX11Info::connection();" is compiled, but of
course, QX11Info has not been defined.
There is a fix in 5.15.3.
Now, how is it that we have not seen that before? I've built
plasma-5.15.0
already once, without error... The only difference I see is that I had
gcc-8.2.0. But I tried to reinstall gcc-8.2.0, and: same error!
I may well be out of my depth here.
