标签: c++ windows qt qt5 mingw32

我正在处理带有子目录的QT项目,它在linux(ubuntu)上运行良好,但是当我尝试在Windows上运行时,我得到未定义对`moduleInterface :: ...的引用其中 ... 指的是我的子目录中的所有方法。我使用的Qt版本(5.11.2)在Linux和Windows中都是相同的。子目录配置如下:

main.pro

TEMPLATE = subdirs

SUBDIRS += \
         tests \
         coreSerialTerm \
         serialTermView

serialTermView.depends = coreSerialTerm
tests.depends = coreSerialTerm

DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs. 
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version     of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs   deprecated before Qt 6.0.0

编译时,出现以下错误:

它看起来像一个编译顺序问题。链接器可能找不到某些符号,因为它们属于其他子项目之一,但尚未处理。

尝试如下更改您的subdirs .pro文件:

TEMPLATE = subdirs

CONFIG += ordered

SUBDIRS += \             
         coreSerialTerm \
         tests \
         serialTermView

.depends属性在Windows上从未真正起作用。
