  • [SOLVED] Could not open J-Link shared library. Exiting now.

    Hello,

    I am using Segger J-Link Ultra+ debugger under GNU/Linux and I am facing some problems with "
    J-Link Software and Documentation pack for Linux, TGZ archive, 64-bit" software package.

    Sometimes when I'm trying to run for example JLinkExe application I get following error:

    # ./JLinkExe
    SEGGER J-Link Commander V6.44g (Compiled Apr 18 2019 17:15:12)
    Could not open J-Link shared library. Exiting now.

    I noticed that this error occurs always after I run "ldconfig" Linux command.
    After run this (ldconfig) command I get another error:

    ldconfig: libraries libjlinkarm.so.6 and libjlinkarm_x86.so in directory /usr/local/JLink_Linux_V644g_x86_64 have same soname but different type.
    ldconfig: libraries libjlinkarm_x86.so and libjlinkarm_x86.so.6.44.7 in directory /usr/local/JLink_Linux_V644g_x86_64 have same soname but different type.

    Seems like the libjlinkarm_x86.so.6.44.7 library is not properly build during linking process, because:

    $ objdump -p libjlinkarm.so.6.44.7 | grep SONAME
    SONAME libjlinkarm.so.6

    $ objdump -p libjlinkarm_x86.so.6.44.7 | grep SONAME
    SONAME libjlinkarm.so.6

    As far as I know these libraries needs to have different sonames but they are the same. Probably "-soname" option of "ld" linker will help with this problem during linking process.

    Hello,
    Yes I know this article from Wiki but it didn't solve my problem - so that is why I sent the post with my solution on the forum.

    Regarding your suggestion - I've just created new support ticket with this bug.
    Thank you.
