4GL

Posted in 1999

Summary

RW compiled a 4GL program with the -shared option and got a dynamic linker error opening lib4gsh720.so. Rahul Dhuvad advised setting LD_LIBRARY_PATH to $INFORMIXDIR/lib/tools. Vicente Salvador suggested a symlink in /usr/lib. Jonathan Leffler listed the library path, ld.so.cache, symlink or link-option routes, and warned not to move INFORMIXDIR after building.

Could anyone help me with the following problem: I am trying to compile my 4gl program using -shared option (I want my exec file to be smaller). I can't run my program - I get message: dynamic linker: error opening lib4gsh720.so Killed What do I need to do to run my program? Thanks in advance, Regards, RW.

Hi, I think you forgot to set LD_LIBRARY_PATH (in Solaris) -or- equivalent <runtime-shared-lib-search-path> environment variable to point to $INFORMIXDIR/lib/tools. i.e. In Solaris, setenv LD_LIBRARY_PATH $INFORMIXDIR/lib/tools #--csh export LD_LIBRARY_PATH=$INFORMIXDIR/lib/tools #--ksh After setting this env. variable, just execute your program(a.out). Hope this helps, Rahul. RW wrote: > > Could anyone help me with the following problem: > I am trying to compile my 4gl program using -shared option (I want my exec > file to be smaller).

Installation of 4GL program is wrong and doesn't creates the appropiate link. 1. Connect as root 2. cd /usr/lib 3 ln -s $INFORMIXDIR/lib/tools/lib4gsh720.so . and compiler should work fine.

Either: ensure $INFORMIXDIR/lib/tools is included in LD_LIBRARY_PATH or its equivalent on your O/S Or: ensure $INFORMIXDIR/lib/tools is handled by ld.so.cache (Linux) Or: add a symlink in /usr/lib referencing $INFORMIXDIR/lib/tools/lib4gsh720.so Or: Decide to add $INFORMIXDIR/lib/tools/lib4gsh720.so to your link options -- but don't move INFORMIXDIR after building your executable. If the code has to be moved to a new machine, the INFORMIXDIR must be in the same place on the new machine. -- Jonathan Leffler (jleffler@informix.com, jleffler@earthlink.net) Guardian of DBD::Informix v0.60 -- see http://www.perl.com/CPAN #include <disclaimer.h>
