我正在尝试将我的 QT 应用程序链接到 DLL (libshout)，同时为 Windows 构建。
我已将适当的行添加到我的 .pro 文件中：
LIBS += -L/local/lib -lmp3lame
LIBS += -L/local/lib -lshout
LIBS += -L/local/lib -logg
LIBS += -L/local/lib -lvorbis
LIBS += -lwsock32
我还成功地构建并安装了 libshout 到 /local/lib（我正在使用 mingw 和 gcc-dw2 编译器）。
但是，qmake 无法成功链接。我在下面粘贴了 gcc/make 输出。我什至不确定它是否正在尝试链接到正确的库（.a/.la 不是静态库吗？）。
我已经为此撕掉了 3 天的头发，所以任何帮助表示赞赏:)
