Informix 14.10.FC8 on RHEL 8.6 installation - missing packages ?

Hello, In the doc i see - Red Hat Enterprise Linux ES release 8.0 (Kernel: 4.18.0-80, Glibc: 2.28-42). The following packages have to be installed: libaio-0.3.110 libgcc_s1-8.2.1 libstdc++6-8.2.1 ncurses-utils-6.1-7 pam-1.3.1-4 elfutils-libelf-0.174-6 When i try to install libgcc_s1 and ncurses-utils I get Error: Unable to find a match and yum whatprovides <package> gives Error: No Matches found But, I have in the system libgcc-8.5.0-10.el8.x86_64 ncurses-6.1-9.20180224.el8.x86_64 Is it OK ? Thanks ------------------------------ Samuel ------------------------------ #Informix

Hi Samuel, I think the informix installer needs libncurses.so.5 and libtinfo.so.5 to run. The workaround for that is : # cd /usr/lib64 # ln -s libncurses.so.6.1 libncurses.so.5 # ln -s libtinfo.so.6.1 libtinfo.so.5 Cheers,Markus​ ​​​ ------------------------------ Markus Holzbauer ------------------------------

Hi Indeed during the first try i had this message Prerequisite Verification Check ------------------------------- One or more prerequisite system libraries are not installed on your computer. Install libncurses.so.5 and then restart the IBM Informix installation And according to advice I received I linked libncurses.so.5 to libncurses.so.6.1 After that i was able to install informix. I didn't have message about libtinfo.so.5 However, there remains the problem of the "missing packages" libgcc_s1 and ncurses-utils and i don't feel comfortable ignoring them. Thanks ------------------------------ Samuel To ------------------------------

Might be a documentation issue. I don't think libgcc_s1 exists in the redhat 8 world. Same for ncurses-utils. I found a reference for an older version in redhat 7 (marked as outdated). rpmfind lists only occurrances for Suse Linux instead. My suggestion: Give it a try to run without. You can also check if all the dependencies are present by using the ldd command on each binary file which is running. $ cd <INFORMIXDIR>/bin $ export LD_LIBRARY_PATH=${INFORMIXDIR}/lib:${INFORMIXDIR}/lib/esql $ ldd *You will see if any required library is missing on your system. This might be the case for some utilities which use external software, but should not produce any "missing" output for the informix standard binaries (such as oninit, onstat, onmode, dbaccess etc.) For my installation (not running redhat). This e.g. gives a "not found" output for libcurses.so.5 for nsradmin and ism_watch and missing libXm.so.4 for ipload. These are all utilities we are not using at all, so we will won't run into any issues. Marcus Haarmann

There are errors in the package names listed under RHEL 8.0. A document defect has been logged. libgcc_s1 and ncurses-utils are the package names for SLES, not RHEL. The correct package name for RHEL should be libgcc and ncurses-compat-libs The version number for these two packages in RHEL 8.0 would be : libgcc-8.2.1 ncurses-compat-libs-6.1-7 Just make sure these two packages are installed as ncurses-compat-libs would create libncurses.so.5 which Informix requires. ------------------------------ Casey Tan ------------------------------

The libgcc_s1 and ncurses-utils are the package names for SLES. A document defect has been submitted for this error. The correct names for RHEL 8.0 should be ncurses-compat-libs-6.1-7 and libgcc-8.2.1 ------------------------------ KHON CHIEK TAN ------------------------------
