  • 1.  Error building sys* databases

    Posted 03/26/20 08:38 PM
    Hello everybody!

    We installed informix 14.10,FC3 on a Red Hat Linux 8.1 distribution (Ootpa), the installation log didn't  have warnings or errors, but, when We try initialized the instance for the first Time, it cannot to build sys* databases, we tried manually to build it with shell 

    $INFORMIXDIR/etc/buildsmi without success..

    The principal error is: 

    dbaccess: error while loading shared libraries: libncurses.so.5: wrong ELF class: ELFCLASS32

    Cleaning up whatever was successfully created

    dbaccess: error while loading shared libraries: libncurses.so.5: wrong ELF class: ELFCLASS32


    We review all the prerequisites in machine notes and it was validated. Though the same machine notes didn't refer RH8 as a certified distribution, but in the Informix Server System Requirements

    Ibm remove preview

       it does. 

    Some ideas? thanks in advance

    Hi, Jessica,

    on RedHat 8.x "libncurses.so.5" is provided by ncurses-compat-libs-6.x, exact package version will depend on the current level of the O/S, for example on RH 8.0 I see

    ncurses-compat-libs-6.1-7.20180224.el8.x86_64

    Make sure the 64-bit version (x86_64) is installed.

    Hope it helps.

    Hi Jessica,
    As I tested on Red Hat 8.1, if ncurses6 is already installed, the bulidsmi script works fine after creating a symbolic link for ncurses5 as shown below.

    ln -s /usr/lib64/libncurses.so.6 /usr/lib64/libncurses.so.5
    ln -s /usr/lib64/libtinfo.so.6 /usr/lib64/libtinfo.so.5

    However, it is recommended to install the compatibility library.
    Installing ncurses-compat-libs with yum or dnf doesn't give any errors and buildsmi works fine.

    Jessica:

    The problem is in this message:
    dbaccess: error while loading shared libraries: libncurses.so.5: wrong ELF class: ELFCLASS32

    Apparently you have a 32bit copy of the ncurses package installed and the Informix engine is a 64bit engine (v14.10 does not support a 32bit release any longer BTW). Install the 64bit ncurses package. If your Linux is 32bit, then you will have to reinstall a 64bit Linux instead.
