我正在将一个巨大的项目从Qt 4.x迁移到5,我差不多完成了但是我遇到了我无法找到的错误,我认为它与某些库的链接有关但我在这里有点迷失。我希望有人可以对这件事情说清楚。
错误:

您正在使用以下库的-L
选项:
-L"./libHDP.a" \
-L"./zlib1.dll" \
-L"./libqxmpp.a" \
-L"./libqextserialportd.a" \
-L
指定搜索库的目录。使用-l
(小写)指定库。如果您想要指定确切的名称,则可能需要在libarary名称前添加冒号。例如,
-l :./libHDP.a \
-l :./zlib1.dll \
-l :./libqxmpp.a \
-l :./libqextserialportd.a \
有关详细信息,请参阅https://sourceware.org/binutils/docs/ld/Options.html#Options。
答案 1 :(得分:3)
./ release \ addeditaton.o:addeditaton.cpp :(。text + 0x6ac2):未定义引用`_imp ___ ZN10HTTPClient5abortEv&#39;
这样的行通常至少意味着以下任何一个问题:
您没有安装相应的库。
您没有使用您所依赖的符号安装正确的版本。
您的关联选项设置不正确。
在这种情况下,抱怨是关于http客户端库的,所以让我们先检查你的项目文件。您在开始时正确使用了-L
和-l
选项,但最终没有使用,所以让我们澄清它们的含义:
-L
表示库的路径。
-l
或者表示库名称或库的绝对路径。
现在,让我们看一下你在问题的最后写的内容:
-L"./libHDP.a" \
#-l../../Qwt/qwt-5.2.0/lib/debug/qwt5 \
#-lqenc \
#-lzlibwapi \
-L"./zlib1.dll" \
#-lqextserialport \
-lsetupapi \
#-lqxmpp \
-L"./libqxmpp.a" \
#-ljson_lib \
#-lSerialPort1
-L"./libqextserialportd.a" \
因此,您应该使用以下内容替换它:
-lHDP
#-l../../Qwt/qwt-5.2.0/lib/debug/qwt5 \
#-lqenc \
#-lzlibwapi \
-lzlib1 \
#-lqextserialport \
-lsetupapi \
#-lqxmpp \
-lqxmpp.a \
#-ljson_lib \
#-lSerialPort1 \
-lqextserialportd
或者,您也可以使用上面提到的-l
选项指定静态库的绝对路径。
请注意,您不应混淆项目中的QtSerialPort和QextSerialPort等内容。最好使用QtSerialPort。
