Question

我正在尝试连接到Qt中的ubuntu上的SQL Server数据库，需要安装ODBC驱动程序。我做了文件告诉我要做的here。并将here中的unixOBDC安装到/usr/local/unixODBC，然后运行这些命令

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

导致一些来源

出现语法错误

如果我现在运行我的代码，这就是我得到的

QSqlDatabase: QODBC driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QPSQL QPSQL7

我缺少什么？

使用错误版本的qmake可能会导致问题。最可能与您在源代码中使用的不一样。

在Linux（Ubuntu）上安装ODBC驱动程序，以便在运行“make”时获取语法错误
