PHP make fails (db2 and informix)

Morning All, I am currently trying to compile PHP4.0.6 (with both informix and db2 support) on a Redhat 7.1 based system. The source was obtain from php.net, blah blah blah. Everything is pretty standard on this end. Here is my configure command: ./configure --with-ibm-db2=/usr/IBMdb2/V7.1 --with-informix And this is the error I get when I make: In file included from /usr/IBMdb2/V7.1/include/sqlcli1.h:42, from /root/temp/php-4.0.6/ext/odbc/php_odbc.h:170, from internal_functions.c:38: /usr/IBMdb2/V7.1/include/sqlcli.h:323: parse error before `7' /usr/IBMdb2/V7.1/include/sqlcli.h:326: parse error before `5' Some C programmer types have told me it has something to do with the " #define SQLDATE" in the .h files for either informix or db2. Being the non-programmer that I am, this didnt help much... Our developers have a test system up and running and using their excellent documentation skills (none), we have no documentation on how they munged it to get it going. I found some references to this error around, but couldnt locate a resolution. Thanks for any help! ----- Chris Kulish Systems Engineer ING Advisors Network Ph. (515) 698-7583 Fx. (515) 698-3583 -----
