PHP4: ./configure quits with an error

[Anon]

Hi,

I am pretty desperate right now.

I installed Suse 7.0 and
- Apache
- MySQL
- PHP3
worked fine from the beginning (I had to make just a few changes).

Now I want to update to PHP4 (--with-informix=yes). So I got the latest PHP release from the Internet. I deinstalled the old PHP3 (mod_php) with YaST.

Then I call (from /usr/src/php4):

./configure --with-informix=yes

Output:

My Informix-Database & ClientSDK works fine and I don't think (though I am not sure) the error lies within wrong Informix-configuration.

Please help me!

Best regards

Hi ,
php3 and php4 must working correctly together on same server.
you dont must uninstall php3 for use php4...
maybe your uninstall operation delete some necessery elements for php.

It seems, that "bison" and "flex" are not installed by default (Suse Linux). After I installed both packages, it worked.

Thank you anyway. :-)
