@seasea128 thanks, done. Sorry for the delay.

Hi, it seems like kddockwidgets in extra provides Qt6 version now. This package requires kddockwidgets-qt6 and now cannot be installed as kddockwidgets-qt6 will try to override kddockwidget's file.

@jholmer fixed, thanks.

@rmeno12 there is the flag to build it with Qt 6. I enabled it just because Qt 5 has reached the end of its life, and Qt 6 seems to work well.

Am also getting the same build error. I noticed that the upstream repo claims to support Qt5 not Qt6: see here and here. Is there a reason this version builds against Qt6?

This package currently seems to be failing to build:

@krumelmonster it works with both qcustomplot and qcustomplot-qt6, as qcustomplot provides the header file needed here. I updated the PKGBUILD, thanks.

I also moved kgraphviewer from optdepends to depends, as it's not a runtime dependency, so you would have to rebuild the package to use it. Let me know if you want me to move it back to optdepends.

@Rubo odd. qcustomplot-qt6 gives me libqcustomplot-qt6.so.2.1.1 and that has the symbol:

$ nm --demangle --dynamic --defined-only --extern-only  /usr/lib/libqcustomplot-qt6.so.2.1.1 | grep QCPAxisTicker::generate
000000000008bde0 T QCPAxisTicker::generate(QCPRange const&, QLocale const&, QChar, int, QList<double>&, QList<double>*, QList<QString>*)

@krumelmonstern I, on the other hand, get your errors on a clean chroot precisely when I add qcustomplot-qt6 to depends.

Just confirming that installing qcustomplot-qt6 fixed these linker errors so it should be added to depends:

/usr/bin/ld: /tmp/ccxFfXJB.ltrans9.ltrans.o:(.data.rel.ro+0xc18): undefined reference to QCPAxisTicker::generate(QCPRange const&, QLocale const&, QChar, int, QList<double>&, QList<double>*, QList<QString>*)' /usr/bin/ld: /tmp/ccxFfXJB.ltrans9.ltrans.o:(.data.rel.ro+0xc40): undefined reference toQCPAxisTicker::createSubTickVector(int, QList<double> const&)' /usr/bin/ld: /tmp/ccxFfXJB.ltrans9.ltrans.o:(.data.rel.ro+0xc48): undefined reference to QCPAxisTicker::createLabelVector(QList<double> const&, QLocale const&, QChar, int)' /usr/bin/ld: /tmp/ccxFfXJB.ltrans16.ltrans.o: in functionFrequencyPage::FrequencyPage(PerfParser, QWidget)::{lambda()#2}::operator()() const': /usr/src/debug/hotspot/hotspot/src/frequencypage.cpp:136:(.text+0x2c96): undefined reference to `QCPGraph::setData(QList<double> const&, QList<double> const&, bool)' collect2: error: ld returned 1 exit status make[2]: *** [src/CMakeFiles/hotspot.dir/build.make:671: bin/hotspot] Error 1 make[1]: *** [CMakeFiles/Makefile2:1774: src/CMakeFiles/hotspot.dir/all] Error 2 make: *** [Makefile:146: all] Error 2

The link error can be fixed by adding qcustomplot-qt6 to depends, as cmake/FindQCustomPlot.cmake is able to find both qcustomplot{-qt6,} correctly, while libqcustomplot.so provided by extra/qcustomplot is a qt5 library.
