system() returns undefined function, but exec(), passthrou() and the backtick operator works. Running Apache-2.0.40.

Can you please attach a sample script here which shows this problem?  Somehow I doubt this has anything to do with Apache2..but could you check if compiling a CGI and running the test script with it does the same?

 [2002-09-10 00:15 UTC] danne at wiberg dot nu
My script:
$command='/sbin/ping -c 1';
passthru($command); /* This works */
exec($command); /* This works */
system($command); /* This gives undefined function */
My output:
PING ( 56 data bytes 64 bytes from icmp_seq=0 ttl=247 time=14.091 ms --- ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max/stddev = 14.091/14.091/14.091/0.000 ms

I just compiled php standalone, it worked, no undefined function.
 [2002-09-10 19:48 UTC]
Can you try compiling a new apache2 module from _clean_ sources (fresh download from :) and only include
the minimum amount of configure options. (ie. just the --with-apxs2 one)

| In order to build PHP as a Apache2 module on FreeBSD, you have to  |
| add  --with-tsrm-pth to your ./configure line. Therefore you need  |

Should I include this also?

Using --with-apxs2 --with-tsrm-pth

same problem.

Only --with-apxs2 doesn't work, se below:

Syntax error on line 273 of /usr/local/etc/apache2/httpd.conf:
Cannot load /usr/local/libexec/apache2/ into server: /usr/local/libexec/apache2/ Undefined symbol "pthread_getspecific"
 [2002-09-11 08:23 UTC]
So it's yet another apache2 problem then.
Could you also try this snapshot:
 [2002-09-11 16:47 UTC] danne at wiberg dot nu
./configure --with-apxs2
[loads of suff]
checking for Berkeley DB2 support... no
./configure: 21429: Syntax error: "fi" unexpected (expecting "then")

The PHP installation segfaults, but when I compile it against Apache2 I don't get an executable, so how do I debug it?
 [2002-10-05 02:57 UTC]
Yeah, it does that sometimes... just try make install again.
 [2002-10-08 06:13 UTC] danne at wiberg dot nu
Yes, I've tried daily since Sep 14:th. Same coredump. Would be nice if I could contribute with something useful or work around the problem.
 [2002-10-08 22:26 UTC]
Are you able to successfuly complete the make install if you add --without-pear to your confgure line?
 [2002-10-09 16:41 UTC] danne at wiberg dot nu
Tried it and it worked well, I've tried a few applications (squirrelmail, gallery) under this build and it works fine.

But the main thing: system() works!

Thanks a lot, case closed!

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at
In case this was a documentation problem, the fix will show up soon at

In case this was a website problem, the change will show
up on the site and on the mirror sites in short time.
Thank you for the report, and for helping us make PHP better.
