qmake 不会将 .pro 文件中的库添加到 makefile [英] qmake doesn't add libraries from .pro file to the makefile

问题描述

我尝试使用 qmake 构建一个 QT 项目.为此，我需要 boost 库.

I try to build an QT project using qmake. For this I need the boost library.

LIBS += -L/usr/lib/ \
 -lboost_system \
 -lboost_filesystem

但是在运行 qmake 之后，这些库并没有添加到 makefile 中:

But after running qmake, these libraries are not added to the makefile:

LIBS = $(SUBLIBS) -L/usr/X11R6/lib64 -lQt5MultimediaWidgets
-L/build/buildd/qtmultimedia-opensource-src-5.0.1/lib -L/usr/lib/x86_64-linux-gnu
-L/usr/lib/x86_64-linux-gnu/x86_64-linux-gnu -lQt5OpenGL -lQt5Multimedia -lpulse
-lQt5Widgets -lQt5Network -lQt5Gui -lQt5Core -lGL -lpthread

正如预期的那样，链接器打印了许多错误，例如

As expected, the linker prints many error like

/usr/include/boost/system/error_code.hpp:214: error: undefined reference to boost::system::generic_category()

如果您想查看整个 .pro 文件，请转到 https://raw.github.com/francisengelmann/FabScan100/master/qtTest/qtTest.pro

If you want to take a look to the whole .pro file, go to https://raw.github.com/francisengelmann/FabScan100/master/qtTest/qtTest.pro

我也遇到了与 opencv 类似的问题.有谁知道如何解决这个问题?

I am also having a similar problem with opencv. Does anyone know how to solve this issue ?

推荐答案

更改.pro文件后需要再次运行qmake.仅删除您的构建目录是不够的.

You need to run qmake again after changing the .pro file. Just removing your build directory is not enough.

另外你确定你的 qmake 目标是 linux-g++ 吗?INCLUDEPATH 是否有效?

Also are you sure your qmake target is linux-g++? Does the INCLUDEPATH work?
