c++ - 如何使用GTK +设置CMakeList？

我像这样设置CMakeLists:

project(physiotreapy)

set(HEDEAR_FILES Physiotreapy.h)
set(SOURCE_FILES Physiotreapy.cpp)

add_library(libphysiotreapy STATIC ${SOURCE_FILES})
target_include_directories(libphysiotreapy PUBLIC .)

add_executable(physiotreapy ${SOURCE_FILES} main.cpp)

find_package(PkgConfig REQUIRED)
pkg_check_modules(GTK3 REQUIRED gtk+-3.0)

include_directories(${GTK3_INCLUDE_DIRS})
link_directories(${GTK3_LIBRARY_DIRS})

add_definitions(${GTK3_CFLAGS_OTHER})

target_link_libraries(physiotreapy libphysiotreapy )

但是当我尝试运行此代码时:

#include <gtk/gtk.h>

int main (int argc, char *argv[]) {
    GtkWidget *okno;

    gtk_init(&argc,&argv);
    okno = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_widget_show (okno);

    gtk_main ();

    return 0;
}

我收到一些错误:

/cygdrive/c/Users/Mateusz/Desktop/My project/projects/physiotreapy/main.cpp:11: undefined reference to `gtk_init_abi_check'
/cygdrive/c/Users/Mateusz/Desktop/My project/projects/physiotreapy/main.cpp:11:(.text+0x35): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `gtk_init_abi_check'

最佳答案

看起来您那里有95％，但是我认为您忘记列出要链接的库了。我的“FooBar”项目的CMakeList.txt文件的相关部分包含以下内容，其中前3行与您的行几乎相同:

FIND_PACKAGE ( PkgConfig REQUIRED )
PKG_CHECK_MODULES( GTK REQUIRED gtk+-3.0 ) # or use gtk+-2.0, etc...
INCLUDE_DIRECTORIES ( ${GTK_INCLUDE_DIRS} )
SET ( FOOBAR_LIBS ${GTK_LIBRARIES} )

请注意，我在第四行跟踪需要哪些库。然后，当我创建可执行文件时，在我的CMakeLists.txt中:

ADD_EXECUTABLE ( foobar foobar.cpp )
TARGET_LINK_LIBRARIES( foobar ${CMAKE_THREAD_LIBS_INIT} ${FOOBAR_LIBS} )

请注意$ {FOOBAR_LIBS}，在我的例子和许多实际示例中，它包含许多库，而不仅仅是GTK +库。另一种流行的方法是列出这样的库:

ADD_EXECUTABLE ( foobar foobar.cpp )
TARGET_LINK_LIBRARIES( foobar ${CMAKE_THREAD_LIBS_INIT} ${GTK_LIBRARIES} )

如果您需要链接多个包，则将它们全部列出，类似于以下内容:

ADD_EXECUTABLE ( foobar foobar.cpp )
TARGET_LINK_LIBRARIES( foobar ${CMAKE_THREAD_LIBS_INIT} ${GTK_LIBRARIES} ${POSTGRESQL_LIBRARIES} ${OPENGL_LIBRARIES} )
