In continuation of #15 a new error appear during 'Testing if package can be loaded'

If you run R CMD ldd path/to/your/qtbase/src-build/qtbase.so, does the QtBluetooth library show up? Perhaps the linker strips this, since only libsmokeqt.a uses QtBluetooth symbols.

It is not present, no...

I'm facing the very same issue (undefined symbol _ZTI23QBluetoothTransferReply referenced from qtbase.so) on Ubuntu 14.04 LTS, 64-bit, R version 3.1.0 (2014-04-10), Platform: x86_64-pc-linux-gnu (64-bit), with Qt 5.2.1.

R CMD ldd qtbase.so does not show QtBluetooth library, even though I supplied LD_LIBRARY_PATH to a directory containing the library when building qtbase.

qtbase.so linking command was:

This issue is similar to the one we'd been discussing with Michael some time ago on the cranvas google group (see https://groups.google.com/forum/?hl=en#!topic/cranvas/qX2rkNMlKXk). If I try to (iteratively) tweak src/CMakeLists.txt in a way similar to your last solution:

I'm getting further and further facing new and new undefined symbols, and finally I get stuck at:

** testing if installed package can be loaded

In this latter case (tweaking CMakeLists.txt), R CMD ldd qtbase.so found libQt5WebKitWidgets.so in /usr/lib/x86_64-linux-gnu. If I remove that library (and some more) from there, I can load qtbase.so successfully. Why did R try to find the lib in another location than the one supplied via LD_LIBRARY_PATH (which contained the lib as well)?

Hi Tomas,

Please submit a PR for the fixes you needed to get this far. Unfortunately, I have no idea why R is disobeying the LD_LIBRARY_PATH.

R CMD ldd qtbase.so does not show QtBluetooth library, even though I supplied LD_LIBRARY_PATH to a directory containing the library when building qtbase.

qtbase.so linking command was:

This issue is similar to the one we'd been discussing with Michael some time ago on the cranvas google group (see https://groups.google.com/forum/?hl=en#!topic/cranvas/qX2rkNMlKXk). If I try to (iteratively) tweak src/CMakeLists.txt in a way similar to your last solution:

set(LIB_LOC "") if(Qt5Multimedia_FOUND) get_target_property(QtMultimedia_location Qt5::Multimedia LOCATION) set(LIB_LOC ${LIB_LOC} ${QtMultimedia_location}) endif(Qt5Multimedia_FOUND) if(Qt5MultimediaWidgets_FOUND) get_target_property(QtMultimediaWidgets_location Qt5::MultimediaWidgets LOCATION) set(LIB_LOC ${LIB_LOC} ${QtMultimediaWidgets_location}) endif(Qt5MultimediaWidgets_FOUND) if(Qt5Network_FOUND) get_target_property(QtNetwork_location Qt5::Network LOCATION) set(LIB_LOC ${LIB_LOC} ${QtNetwork_location}) endif(Qt5Network_FOUND) if(Qt5Qml_FOUND) get_target_property(QtQml_location Qt5::Qml LOCATION) set(LIB_LOC ${LIB_LOC} ${QtQml_location}) endif(Qt5Qml_FOUND) if(Qt5Quick_FOUND) get_target_property(QtQuick_location Qt5::Quick LOCATION) set(LIB_LOC ${LIB_LOC} ${QtQuick_location}) endif(Qt5Quick_FOUND) if(Qt5Sql_FOUND) get_target_property(QtSql_location Qt5::Sql LOCATION) set(LIB_LOC ${LIB_LOC} ${QtSql_location}) endif(Qt5Sql_FOUND) if(Qt5Test_FOUND) get_target_property(QtTest_location Qt5::Test LOCATION) set(LIB_LOC ${LIB_LOC} ${QtTest_location}) endif(Qt5Test_FOUND) if(Qt5Webkit_FOUND) get_target_property(QtWebkit_location Qt5::Webkit LOCATION) set(LIB_LOC ${LIB_LOC} ${QtWebkit_location}) endif(Qt5Webkit_FOUND) if(Qt5WebKitWidgets_FOUND) get_target_property(QtWebKitWidgets_location Qt5::WebKitWidgets LOCATION) set(LIB_LOC ${LIB_LOC} ${QtWebKitWidgets_location}) endif(Qt5WebKitWidgets_FOUND) if(Qt5DBus_FOUND) get_target_property(QtDBus_location Qt5::DBus LOCATION) set(LIB_LOC ${LIB_LOC} ${QtDBus_location}) endif(Qt5DBus_FOUND) if(Qt5Svg_FOUND) get_target_property(QtSvg_location Qt5::Svg LOCATION) set(LIB_LOC ${LIB_LOC} ${QtSvg_location}) endif(Qt5Svg_FOUND) if(Qt5XmlPatterns_FOUND) get_target_property(QtXmlPatterns_location Qt5::XmlPatterns LOCATION) set(LIB_LOC ${LIB_LOC} ${QtXmlPatterns_location}) endif(Qt5XmlPatterns_FOUND) if(Qt5PrintSupport_FOUND) get_target_property(QtPrintSupport_location Qt5::PrintSupport LOCATION) set(LIB_LOC ${LIB_LOC} ${QtPrintSupport_location}) endif(Qt5PrintSupport_FOUND) if(Qt5Help_FOUND) get_target_property(QtHelp_location Qt5::Help LOCATION) set(LIB_LOC ${LIB_LOC} ${QtHelp_location}) endif(Qt5Help_FOUND) if(Qt5UiTools_FOUND) get_target_property(QtUiTools_location Qt5::UiTools LOCATION) set(LIB_LOC ${LIB_LOC} ${QtUiTools_location}) endif(Qt5UiTools_FOUND) if(Qt5SerialPort_FOUND) get_target_property(QtSerialPort_location Qt5::SerialPort LOCATION) set(LIB_LOC ${LIB_LOC} ${QtSerialPort_location}) endif(Qt5SerialPort_FOUND) if(Qt5Sensors_FOUND) get_target_property(QtSensors_location Qt5::Sensors LOCATION) set(LIB_LOC ${LIB_LOC} ${QtSensors_location}) endif(Qt5Sensors_FOUND) if(Qt5Bluetooth_FOUND) get_target_property(QtBluetooth_location Qt5::Bluetooth LOCATION) set(LIB_LOC ${LIB_LOC} ${QtBluetooth_location}) endif(Qt5Bluetooth_FOUND) if(Qt5Positioning_FOUND) get_target_property(QtPositioning_location Qt5::Positioning LOCATION) set(LIB_LOC ${LIB_LOC} ${QtPositioning_location}) endif(Qt5Positioning_FOUND) if(Qt5Nfc_FOUND) get_target_property(QtNfc_location Qt5::Nfc LOCATION) set(LIB_LOC ${LIB_LOC} ${QtNfc_location}) endif(Qt5Nfc_FOUND) target_link_libraries(qtbase smokeqt ${R_LIBRARIES} ${LIB_LOC})

I'm getting further and further facing new and new undefined symbols, and finally I get stuck at:

\ testing if installed package can be loaded Error : .onLoad failed in loadNamespace() for 'qtbase', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/home/sieger/R-qt5/x86_64-pc-linux-gnu-library/3.1/qtbase/libs/qtbase.so': /home/sieger/R-qt5/x86_64-pc-linux-gnu-library/3.1/qtbase/libs/qtbase.so: undefined symbol: _ZNK17QWebHitTestResult8mediaUrlEv

Note that the _ZNK17QWebHitTestResult8mediaUrlEv symbol is defined in libQt5WebKitWidgets.so.

In this case, qtbase.so linking command was:

In this latter case (tweaking CMakeLists.txt), R CMD ldd qtbase.so found libQt5WebKitWidgets.so in /usr/lib/x86_64-linux-gnu. If I remove that library (and some more) from there, I can load qtbase.so successfully. Why did R try to find the lib in another location than the one supplied via LD_LIBRARY_PATH (which contained the lib as well)?

With the recent rework of the linking, I think this issue is resolved. Please open a new one if things do not work.
