Hi, Ubuntu 20.04 dropped the qt4 from its official repo, but sometimes I still want to use it. So I try to compile it from the source but failed. See the info below:
$ wget https://download.qt.io/archive/qt/4.8/4.8.7/qt-everywhere-opensource-src-4.8.7.tar.gz $ tar -zxvf qt-everywhere-opensource-src-4.8.7.tar.gz $ cd qt-everywhere-opensource-src-4.8.7 $ ./configure # The following step failed for Ubuntu 20.04: $ make -j4 ../../include/QtCore/../../src/corelib/tools/qpair.h:62:20: note: because ‘QPair<int, int>’ has user-provided ‘QPair<T1, T2>& QPair<T1, T2>::operator=(const QPair<T1, T2>&) [with T1 = int; T2 = int]’ 62 | QPair<T1, T2> &operator=(const QPair<T1, T2> &other) | ^~~~~~~~ make[1]: *** [Makefile:18175: .obj/release-shared/qsslsocket_openssl.o] Error 1 make[1]: Leaving directory '/home/werner/Downloads/qt-everywhere-opensource-src-4.8.7/src/network' make: *** [Makefile:278: sub-network-make_default-ordered] Error 2 Any hints for this problem?
