    Hi!

    I have a problem using the environment variable LD_LIBRARY_PATH in my
    perl script. Everything works fine when I set it at the command prompt
    and then runs my perl script like this:

    presto1@S0222035> echo $LD_LIBRARY_PATH
    /SSW/informix/sdk2.50/lib:/SSW/informix/sdk2.50/lib/esql
    presto1@S0222035> ldd
    /usr/perl5/5.6.1/site_perl/sun4-solaris/auto/DBD/Informix.so
            libifsql.so => /SSW/informix/sdk2.50/lib/esql/libifsql.so
            libifasf.so => /SSW/informix/sdk2.50/lib/libifasf.so
            libifgen.so => /SSW/informix/sdk2.50/lib/esql/libifgen.so
            libifos.so => /SSW/informix/sdk2.50/lib/esql/libifos.so
            libifgls.so => /SSW/informix/sdk2.50/lib/esql/libifgls.so
            libnsl.so.1 => /usr/lib/libnsl.so.1
            libsocket.so.1 => /usr/lib/libsocket.so.1
            libaio.so.1 => /usr/lib/libaio.so.1
            libm.so.1 => /usr/lib/libm.so.1
            libdl.so.1 => /usr/lib/libdl.so.1
            libelf.so.1 => /usr/lib/libelf.so.1
            libifglx.so => /SSW/informix/sdk2.50/lib/esql/libifglx.so
            libc.so.1 => /usr/lib/libc.so.1
            libmp.so.2 => /usr/lib/libmp.so.2
            /usr/platform/FJSV,GPUS/lib/libc_psr.so.1

    and running

    presto1@S0222035> ./ins_rutin.pl presto db-ladd-lan06
    presto1@S0222035> echo $?
    0

    executes without error messages and carries out the expected
    operations against the database.

    On the other hand, when I have a LD_LIBRARY_PATH like

    presto1@S0222035> echo $LD_LIBRARY_PATH
    /SSW/informix9.4/lib:/SSW/informix9.4/lib/esql:/SSW/informix9.4/lib/tools

    and instead adds a row setting LD_LIBRARY_PATH in the perl script

    $ENV{"LD_LIBRARY_PATH"}="/SSW/informix/sdk2.50/lib:/SSW/informix/sdk2.50/lib/esql";

    invoking the script gives this

    presto1@S0222035> ./ins_rutin.pl presto db-ladd-lan06
    install_driver(Informix) failed: Can't load
    '/usr/perl5/5.6.1/site_perl/sun4-sol
    aris/auto/DBD/Informix/Informix.so' for module DBD::Informix: ld.so.1:
    /usr/bin/
    perl: fatal: libifsql.so: open failed: No such file or directory at
    /usr/perl5/5
    .6.1/sun4-solaris/DynaLoader.pm line 206.
     at (eval 1) line 3
    Compilation failed in require at (eval 1) line 3.
    Perhaps a required shared library or dll isn't installed where
    expected
     at ./ins_rutin.pl line 35

    Why does this happen?

    Some info:

    presto1@S0222035> perl -v

    This is perl, v5.6.1 built for sun4-solaris

    presto1@S0222035> uname -a
    SunOS S0222035 5.8 Generic sun4us sparc FJSV,GPUS
