Right, AFAIK... somebody here posted that they had success with 4GL after installing a backward-compatibility compiler package and specifying that (gcc-based) compiler executable in INFORMIXC. >I know I've run into problems with the 7.24.UC5 ESQL/C on RH6.0 >because system call or function _xstat() is not defined, but I've not >yet tested I4GL et al. Why would you use 7.24.UC5 rather than Client 2.10's ESQL/C? >> PATH=/usr/local/bin:/bin:/usr/bin:/usr/info>> rmix/4gl720ud7_linux/bin:/usr/informix/4glrds720ud7_linux/bin:/usr/informix/4gli >> d720ud7_linux/bin:/usr/informix/sql720ud7_linux/bin:/usr/informix/bin Uh, I don't like this at all. All of your Informix products should be installed in a *single* INFORMIXDIR... I don't think you can mix and match across multiple INFORMIXDIRs, can you? >> LD_RUN_PATH=/usr/informix/4gl720ud7_linux/lib/tools:/usr/informix/sql720ud7_linux/ >> lib/tools:/usr/informix/lib >> LD_LIBRARY_PATH=/usr/informix/4gl720ud7_linux/lib/tools:/usr/informix/>> sql720ud7_linux/lib/tools:/usr/informix/lib But where are the entries for IDS's and Client's shared libraries? Again, I think you need everything in one INFORMIXDIR, then bring in lib, lib/esql, lib/tools, etc. (e.g. lib/c++, lib/cli, lib/dmi, if you need them too) into LD_LIBRARY_PATH. >> Starting up my configured db server, I see various messages before >> successful startup : >> dupfd:fd 1025, max 1024 >> ... >> dupfd:fd 1048, max 1024 >> (Does anyone know if these messages indicate a problem waiting to occur >> ?) > >Possibly.

It's only for soctcp, and I haven't had a chance to look into it... this message is VERY odd for Red Hat 6.0, though. Is this a beta version of Red Hat?
