install from source code on windows

[lynnsky]

hello,I install it according to https://github.com/introlab/rtabmap/wiki/Installation#windows.
I finished the first eight steps.But the next step I did't discover RTABMap.exe.So how can I get the RTABMap.exe.I will show you what I get now:

I think you miss some dependent libraries.
For example, you do not have rtabmap_gui.dll so I guess you didn't have Qt.

Your project list is a little different from mine.
Here is my project list.

Indeed, RTAB-Map.exe is built only if Qt is detected by CMake.

I add these three lines to solve it.But another error appears.I add 'D:\pcl\4.8.0\bin' to noEventsExampleProject -> Properties -> Configuration Properties -> VC++ Directories -> Executable Directories.It does't work.

Set the "QT_MOC_EXECUTABLE" a full path for the executable file, moc.exe.

You don't have to change the CMakeLists.txt. CMake tries already to find Qt here (setting all Qt macros):

IF("${RTABMAP_QT_VERSION}" STREQUAL "4")
        FIND_PACKAGE(Qt4 COMPONENTS QtCore QtGui QtSvg)
ELSE()
        FIND_PACKAGE(Qt5 COMPONENTS Widgets Core Gui Svg)
ENDIF()

Which Qt version do you have?

• For Qt4, make sure the bin directory of Qt is in the PATH environment variable so that CMake can find qmake tool when searching for Qt.
• For Qt5, you can put in the PATH the directory containing Qt5Config.cmake (somewhere inside the Qt5 installation directory) or execute CMake like this: cmake -DRTABMAP_QT_VERSION=5 -DQt5_DIR=path/to/directory/of/Qt5Config.cmake

cheers

Thanks to you all.
@matlabbe I use qt4 and bin directory of Qt is in thepathenvironment.I wonder there is no FindQT.cmakefile in cmake_modules directory ,how can it find qt?
@Wade5566 I set a full path.It works.

[matlabbe]

FindQt4.cmake is already in CMake installation (cmake/share/modules/FindQt4.cmake). What is your CMake output?

[lynnsky]

I findFindQt4.cmakein CMake installation.It is so interesting.I don't know why CMake output this:
Could NOT find Qt4 (missing: QT_MOC_EXECUTABLE QT_RCC_EXECUTABLE QT_UIC_EXECUTABLE) (found version "4.8.0")

[matlabbe]

It is like the development tools are not found by CMake. You could try to execute cmake-gui in Administrator mode. Otherwise, use the solution of @Wade5566 by setting manually the missing tool path.

OK.Thank for your help.
