| Debugging symbols allow you to debug your application better. Debugging symbols are added to your binary by the compiler. You have to decide during the cmake step if you want debugging symbols or not. To compile your application with debugging symbols, use
| | {{Moved To Community | Guidelines_and_HOWTOs/Debugging }} |
| cmake . -DCMAKE_BUILD_TYPE=debugfull
| |
| to compile it without debugging symbols, use
| |
| cmake . -DCMAKE_BUILD_TYPE=release
| |
| Depending on your decision, output generated with the command kDebug will also be (debugfull) or not be (release) added to your application.
| |
| | |
| As an example, let's start with a hello world application.
| |
| | |
| '''main.cpp'''
| |
|
| |
| <pre>
| |
| #include <KApplication>
| |
| #include <KAboutData>
| |
| #include <KCmdLineArgs>
| |
| #include <KMessageBox>
| |
|
| |
| int main (int argc, char *argv[])
| |
| {
| |
| KAboutData aboutData(
| |
| // The program name used internally.
| |
| "tutorial1",
| |
| // The message catalog name
| |
| // If null, program name is used instead.
| |
| 0,
| |
| // A displayable program name string.
| |
| ki18n("Tutorial 1"),
| |
| // The program version string.
| |
| "1.0",
| |
| // Short description of what the app does.
| |
| ki18n("Displays a KMessageBox popup"),
| |
| // The license this code is released under
| |
| KAboutData::License_GPL,
| |
| // Copyright Statement
| |
| ki18n("(c) 2007"),
| |
| // Optional text shown in the About box.
| |
| // Can contain any information desired.
| |
| ki18n("Some text..."),
| |
| // The program homepage string.
| |
| "http://tutorial.com/",
| |
| // The bug report email address
| |
| | |
| | |
| KCmdLineArgs::init( argc, argv, &aboutData );
| |
| KApplication app;
| |
| KGuiItem yesButton( i18n( "Hello" ), QString(),
| |
| i18n( "This is a tooltip" ),
| |
| i18n( "This is a WhatsThis help text." ) );
| |
| KMessageBox::questionYesNo( 0, i18n( "Hello World" ),
| |
| i18n( "Hello" ), yesButton );
| |
| return 0;
| |
| }
| |
| </pre>
| |
| '''CMakeLists.txt'''
| |
| <pre>
| |
| project (tutorial1)
| |
| find_package(KDE4 REQUIRED)
| |
| include (KDE4Defaults)
| |
| include_directories(${KDE4_INCLUDES})
| |
| set(tutorial1_SRCS main.cpp)
| |
| kde4_add_executable(tutorial1 ${tutorial1_SRCS})
| |
| target_link_libraries(tutorial1 ${KDE4_KDEUI_LIBS})
| |
| install(TARGETS tutorial1 ${INSTALL_TARGETS_DEFAULT_ARGS})
| |
| </pre>
| |
| Now let's compile this without debugging symbols:
| |
| cmake . -DCMAKE_BUILD_TYPE=release
| |
