Hi all, It's a little strange, to see the final error, because I got no error message during building. 1. configure Apache with no option 2. cd to PHP4 3. set IFX_LIBS , IFX_INCDIR, IFX_LIBDIR 3. ./configure --wih-informix=/usr/informix --with-apache=../apache_1.3.19 --without-mysql --prefix=/usr/local/bin 4. make / make install PHP4 , it looks fine 5. cd to Apache direcotyr, configure with --activate-module=src/modules/php4/libphp4.a and --enable-module=php4 6. make ... I got a lot of error, so many undefined symbol : sqli_connect_close SQLSTATE sqli_prep ifx_lo_write ... ... .. (about 3 pages ), and all the undefined symbol , their reference are the same : modules/php4/libphp4.a (ifx.o) Most strange things are I really didn't get any fatal error message to stop me to go on.:) can help?
