在CMake Qt项目中链接和UIC顺序 [英] Linking and UIC order in a CMake Qt project
本文介绍了在CMake Qt项目中链接和UIC顺序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
谈论一个使用cmake的buildt的Qt 5.3.2项目。
这是UIC执行和target_link_libraries之间的调用顺序问题...不幸的是不是顺序。
会找到
1。）a CMakeLists.txt和
2的一个（仍然有效）摘录部分。 ）命令cmake的输出的摘录。
3。）不使用
生成的对'make'的下一个调用的输出
使进程崩溃，找不到头。查看
非崩溃make输出显示了原因：
[..]
扫描依赖关系目标qt
[29％]构建CXX对象CMakeFiles / qt.dir / home / kochmn / projects / sentinel / src / qt / form_main.cpp.o
[35％]构建CXX对象CMakeFiles / qt .dir / qt_automoc.cpp.o
链接CXX静态库libqt.a
[..]
[52％]生成ui_main.h
[..]
Make会在之前生成 libqt.a 头文件。
所以我尝试使用像
target_link_libraries（sentinel
$ {Qt5Widgets_LIBRARIES} $ {Qt5Gui_LIBRARIES} $ {Qt5Core_LIBRARIES}）
add_library（优化$ {DIR_SRC} /optimization/linalg.cpp）
add_library（qt$ {DIR_SRC} /qt/form_main.cpp）
target_link_libraries（sentinel qt optimization）
无效。问题：如何激励cmake 先运行UIC生成ui头文件，然后编译我的 libqt.a

[100％]建立目标sentinel $ b CMake生成顺序是根据文件和目标之间的依赖关系计算的。 如果您的 qt 库依赖于.ui文件生成的头文件，那么您必须在目标的输入中添加$ {qt_UI_H}c> qtQT5_WRAP_UI（qt_UI_H $ {qt_UI}）
。]
add_library（qt$ {DIR_SRC} /qt/form_main.cpp$ {qt_UI_H}）
并且CMake应该在编译之前通常在.ui文件上执行UIC。
libqt
target_link_libraries只能设置目标之间的依赖关系（在链接时）。在编译时，正常的行为是找到所有源文件。在你的情况下，生成一些头，所以设置这些头作为目标的输入，确保生成它们的宏（QT5_WRAP_UI）将在目标编译之前执行。Talking about a Qt 5.3.2 project which is buildt using cmake. This is a calling order problem between UIC execution and target_link_libraries... unfortunately not in that order.
Below this text you will find
1.) a (still functional) excerpt section of my CMakeLists.txt and
2.) an excerpt of the the output of the command 'cmake .'
3.) the output of a following call to 'make' without using the generated headers like 'ui_main.h'.
If (in the source of my library libqt.a) I require 'ui_main.h' the make process crashes not finding the header. Looking at the non-crashing make output shows why:
[..] Scanning dependencies of target qt [ 29%] Building CXX object CMakeFiles/qt.dir/home/kochmn/projects/sentinel/src/qt/form_main.cpp.o [ 35%] Building CXX object CMakeFiles/qt.dir/qt_automoc.cpp.o Linking CXX static library libqt.a [..] [ 52%] Generating ui_main.h [..]Make would generate libqt.a before generating the required header file. So I experimented using code like
target_link_libraries(sentinel ${Qt5Widgets_LIBRARIES} ${Qt5Gui_LIBRARIES} ${Qt5Core_LIBRARIES}) add_library(optimization "${DIR_SRC}/optimization/linalg.cpp") add_library(qt "${DIR_SRC}/qt/form_main.cpp") target_link_libraries(sentinel qt optimization)to no avail. The question: How can I motivate cmake to first run UIC generating the ui-header files and then compiling my libqt.a?

解决方案CMake generation order is computed from dependencies between files and targets. If your qt library depends on headers generated from .ui files, then you have to add
${qt_UI_H}in inputs of targetqt:QT5_WRAP_UI(qt_UI_H ${qt_UI}) [...] add_library(qt "${DIR_SRC}/qt/form_main.cpp" ${qt_UI_H})And CMake should normally execute UIC on .ui files before compiling
libqtBy the way using
target_link_librariesonly set dependencies between targets at link time. At compile time, the normal behavior is "All source files should be found". In your case, some headers are generated, so setting these headers as input of a target ensures that the macro which generates them (QT5_WRAP_UI) will be executed before the compilation of the target.这篇关于在CMake Qt项目中链接和UIC顺序的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
