Qt 5.01 does not start on Red Hat Linux 6 or Oracle Linux

  • Hi,

    I have Red Hat Enterprise Linux 6 64-bit and I tried to install Qt 5.0.1 64-bit for Linux and it ran in to the following error:
    Failed to load core: /u02/app/Qt/Tools/QtCreator/lib/qtcreator/plugins/QtProject/libCore.so: Cannot load library /u02/app/Qt/Tools/QtCreator/lib/qtcreator/plugins/QtProject/libCore.so: (/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found (required by /u02/app/Qt/Tools/QtCreator/lib/qtcreator/plugins/QtProject/../.././libQt5CLucene.so.5))

    The libstdc++.so.6 is the latest release that it can possibly be but it's latest GLIBCXX is GLIBCXX_3.4.13 and not GLIBCXX_3.4.15. I used strings on it and greped for GLIBCXX.

    I have tried setting LIBS and other environment variables but it has not worked. I have seen posts that suggest rebuilding/make gcc but I do not think that seems to be the issues.

    Thanks in advance!

    Hi and welcome to devnet,

    You either need to update your system to get a more recent version of libstdc++ or compile Qt yourself.

    You can search this forum for similar questions and get hints from these too
