在 Linux (Ubuntu) 上为 Qt 安装 ODBC 驱动程序在 运行 "make" 时出现语法错误
Installing ODBC driver on Linux (Ubuntu) for Qt getting syntax error while running "make"
我正在尝试在 Qt 中连接到 ubuntu 上的 SQL 服务器数据库，并且需要安装 ODBC 驱动程序。
我做了文件告诉我做 here. And installed unixOBDC from here 到 /usr/local/unixODBC 然后 运行 执行这些命令
cd ~/Qt5.7.0/5.7/Src/qtbase/src/plugins/sqldrivers/odbc
qmake "INCLUDEPATH+=/usr/local/unixODBC/include" "LIBS+=-L/usr/local/unixODBC/lib -lodbc"
make
这导致了几个来源中的语法错误
这就是我现在 运行 我的代码
得到的结果
QSqlDatabase: QODBC driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7
我错过了什么？

问题可能是使用了错误版本的qmake导致的。它很可能与您在源代码中使用的不一样。
我正在尝试在 Qt 中连接到 ubuntu 上的 SQL 服务器数据库，并且需要安装 ODBC 驱动程序。
