PHP4 rc1 and include_path error

Hi folks, I've found references to other people having this problem in the list archives, but I couldn't find an answer, so I'm asking the list. I've done a fresh install of PHP4RC1 and Apache 1.3.12 on my Solaris 2.7 box. Evrything seemed to install okay, and PHP is being invoked on my script files. However, all scripts, including the "hello world" script I've included below, result in an error: Warning: Failed opening '<path to script>' for inclusion (include path='<some path>') in Unknown on line 0 Here's the script: <? echo "hello world"; ?> Needless to say, I'm not using include() in this script. I've tried various settings of the include_path to no avail. What am I missing? thanks - Darryl
