Re: exec() system() help!!! dynamic libraries problem?

Check the error codes you are getting (the optional *third* arg in exec()). Also, check out what "nobody" has for their "path" Env variable: echo GetEnv("path"), "<BR>\n"; Perhaps you just need to SetEnv() that to have the shared libraries in it. SetEnv("path=" . GetEnv("path") . "/some/path/to/shared/libs/:/more/shared/libs"); Also triple-check that the non-working commands aren't in /usr/sbin or some other place not in the path. You can either exec("/usr/sbin/command" ...) (IE, give the full path to the command, whatever it may be) or use SetEnv to make more commands available. I'm assuming shared libraries are found in the path, but what do I know? You may have to resort to writing a shell script for the commands that need libraries, something not unlike this: ----- mycommand ---------------- #!/bin/ash export LD_PRELOAD=/full/path/to/somelib.so.1 exec command $@ ------------------------------------ and then in PHP use exec("mycommand"...) Hey... I'm just realizing that maybe you could use SetEnv for the LD_PRELOAD thing... I have to do all this just to run PHP as CGI with the Postgres libraries in the first place, but you already have PHP running... ----- Original Message ----- From: Sergiy P Zhenochin <serega@ics.uci.edu> Newsgroups: php.general Sent: Tuesday, December 05, 2000 5:41 PM Subject: [PHP] exec() system() help!!! dynamic libraries problem? > > I have php-4.0.0 compiled as an Apache module on RedHat > 6.2, i386.
