1.

/root/Desktop/hero/MyTCPServer-build-desktop/../MyTCPServer/ui_tcpserverwindow.h:13: error: QtWidgets/QAction: No such file or directory

將QtWidgets換成QtGui

2.

/root/Desktop/ hero/MyTCPServer-build-desktop/../MyTCPServer/tcpserverwindow.cpp:96: error: ‘class QHeaderView’ has no member named ‘setSectionResizeMode’

TableView之中的問題:
QT5.x之後將setResizeMode改成了 setSectionResizeMode所以講Section去掉即可

3.

/root/Desktop/hero/MyTCPServer-build-desktop/../MyTCPServer/tcpserverwindow.cpp:146: error: ‘itoa’ was not declared in this scope

itoa並非標準類庫，將其換成sprintf(tmp,”%d”,i+1); 用sprintf即可

4.

/root/Desktop/hero/MyTCPServer-build-desktop/../MyTCPServer/ui_tcpserverwindow.h:57: error: ‘QStringLiteral’ was not declared in this scope

問題出在TCPServerWindow->setObjectName(QStringLiteral(“TCPServerWindow”));這句話
QT 4.8 setObjectName 沒有QStringLiteral這個 形參是QSTring 所以去掉這個QStringLiteral即可

5.

/root/Desktop/hero/MyTCPServer-build-desktop/../MyTCPServer/mytcpsocket.cpp:19: error: ‘Qt_5_6’ is not a member of ‘QDataStream’

當然Qt4.8怎麼會有5.6 改成4.8以下即可

5.之前怎樣配置的的編譯環境儘量與之前一樣。要不會出現與錯誤提示不和的錯誤。
比如說出現瞭如下的空指標異常，其實只是編譯環境不同找不到檔案。
Signal received
The inferior stopped because it received a signal from the Operating System.
Signal name : SIGSEGV
Signal meaning : Segmentation fault
這是錯誤說明程式中有空指標，斷點以下很容易找出錯誤所在！！！！
