Qt Linking Error? #5397
Qt Linking Error?
#5397

|
I tried to build a qt project with xmake: add_rules("mode.debug", "mode.release", "mode.releasedbg")
-- Set the languages used in the project
set_languages("c++17")
add_requires("eigen >=3.4.0")
add_requires("fmt >=8.1.1")
add_requires("boost =1.78.0")
add_requires("nlohmann_json =3.10.5")
add_requires("polyscope")
add_requires("tbb")
add_requires("qt5base =5.15.2")
add_requires("qt5core")
add_requires("qt5gui")
--add_requires("qt5lib =5.15.2")
add_requires("qt5network")
add_requires("qt5webview")
add_requires("qt5widgets")
--add_requires("opengl")
--add_requires("glu")
-- Define the target executable
target("StitchMeshQt")
set_kind("binary")
-- Include headers from these directories
add_includedirs("StitchMeshQt", "persist_contact")
add_files("StitchMeshQt/*.cpp")
add_files("persist_contact/*.cpp")
--add_files("*.cpp")
add_packages("eigen", "fmt", "boost", "nlohmann_json", "polyscope", "tbb")
add_packages("qt5base", "qt5core", "qt5gui", "qt5lib", "qt5network", "qt5webview", "qt5widgets")
--add_packages("opengl", "glu")
if is_plat("windows") then
--add_syslinks("opengl32", "glu32")
-- Add WIN32 macro definition
add_defines("WIN32")
endThe compilation staged worked well, but why am I getting these linking errors? |

add_rules("qt.widgetapp")
add_frameworks("QtCore", "QtGui", "QtOpenGL", "QtWidgets")
add_defines("Q_OBJECT", "Q_GADGET", "Q_NAMESPACE", "Q_NAMESPACE_EXPORT")这样会少一些linking error： 似乎少了一些widget的东西？ |

这个是没进行moc，导致Qt的metaObject没出来，你把带Q_OBJECT的.h写到add_files里就可以了 |
