無法在Ubuntu 16.10，perl的版本上安裝QtCore4 5.24.1

Question

我試圖在Ubuntu 16.10安裝QtCore4，perl的版本5.24.1：

sudo apt-get install cmake 
sudo apt-get install qt4-designer libqtgui4-perl 
cpan -g QtCore4 
bunzip2 Qt4-0.99.0.tar.bz2 
tar xvf Qt4-0.99.0.tar 
cd Qt4-0.99.0 
perl Makefile.PL 
make VERBOSE=1 

這裏make失敗，錯誤消息：

這些線程可能涉及：

• What is this error message about implicitly deleted virtual destructors?

• PythonQt Dynamic Python binding for Qt Applications: build error in C++11 mode

Answer 1

好像有在派生類x_QDBusConnectionInterface缺少析構函數：

/home/hakon/Qt4-0.99.0/smokeqt/qtdbus/x_1.cpp:1594:7: note: ‘virtual __smokeqtdbus::x_QDBusConnectionInterface::~x_QDBusConnectionInterface()’ is implicitly deleted because the default definition would be ill-formed:

通過/home/hakon/Qt4-0.99.0/smokeqt/qtdbus/x_1.cpp在線路1595插入默認析構函數：

~x_QDBusConnectionInterface(); 

錯誤消失編輯。然而，其他三個文件，現在也有這個丟失的析構函數錯誤：

• /home/hakon/Qt4-0.99.0/smokeqt/qtgui/x_3.cpp:4024

• /home/hakon/Qt4-0.99.0/smokeqt/qtgui/x_13.cpp:3572

• /home/hakon/Qt4-0.99.0/smokeqt/qthelp/x_1.cpp:873

修復這些錯誤的方式和第一個相同，仍然出現新的錯誤：

/home/hakon/Qt4-0.99.0/qtcore/src/util.cpp: In function ‘void 
XS_AUTOLOAD(CV*)’: /home/hakon/Qt4-0.99.0/qtcore/src/util.cpp:2234:59: 
error: cannot convert ‘bool’ to ‘void*’ in initialization  
    static smokeperl_object nothis = { 0, 0, 0, false }; 
                ^

的smokeperl_object定義在/home/hakon/Qt4-0.99.0/qtcore/src/smokeperl.h第9行給出：

struct smokeperl_object { 
    bool allocated; 
    Smoke* smoke; 
    int classId; 
    void* ptr; 
}; 

根據這個定義，取代了false在/home/hakon/Qt4-0.99.0/qtcore/src/util.cpp:2234用0似乎是一個很好的嘗試：

static smokeperl_object nothis = { 0, 0, 0, 0 }; 

沒有重新編譯修復此錯誤，但顯示鏈接器錯誤：

我仍然不知道如何解決這個最後的錯誤..
