Errors Compiling PHP 4.3.1 with Apache 2

Hey, I had the same problem and it took me a few days to fix and needed a lot of help from different people. In a nutshell, this is what I did: Th files under ext/mysql/lib/ do not have a reference to errno.h file which they need. Therefore, I manually added an #include <errno.h> to the following files. vi ext/mysql/libmysql/mysql.h vi ext/mysql/libmysql/my_malloc.c vi ext/mysql/libmysql/my_realloc.c vi ext/mysql/libmysql/my_delete.c vi ext/mysql/libmysql/my_tempnam.c vi ext/mysql/libmysql/my_error.c vi ext/mysql/libmysql/my_getwd.c vi ext/mysql/libmysql/my_setwd.c vi ext/mysql/libmysql/my_once.c vi ext/mysql/libmysql/safemalloc Doing the above should take care of those errors. If in the future you want to install the --with-mysql, I ran into problems with this aswell. The functions in php_folder/ext/mysql/libmysql/my_tempnam.c are not being used but referenced by another file(s). Therefore what I did I: 1) Removed the reference to my_tempnam.c from ext/mysql/config.m4 file. 2) Commented out all the contents of the my_tempnam.c file. Can't believe I had to work so hard to get this to work. Good Luck, Felderi Santiago
