我正在尝试将TagLib library用于QT，但我遇到以下错误：
error adding symbols: DSO missing from command line
你知道什么是错误以及如何解决它？
感谢。

您必须添加动态库的路径（DSO-Dynamic Shared Object），例如，如果您的dll-->(libName.dll)或.so --> libName.so
将以下命令添加到.pro文件中：
INCLUDEPATH += "{1}"
LIBS += -L"{2}"
LIBS += -lName
其中：
1: Path of headers (.h files)
2: Path of the .dll file (Windows) or .so (Linux)
在我的情况下，文件位于：

所以我将按如下方式配置它：
INCLUDEPATH += "/usr/include/taglib"
LIBS += -L"/usr/lib/"
LIBS += -ltag
在我的代码中，我将包含以下库：
#include <aifffile.h>
