It seems that the functions in my_tempnam.c are not used.  If I removed my_tempnam.c from ext/mysql/config.m4 php builds and seems to run correctly.

config.m4
53c53
<       libmysql/my_delete.c libmysql/my_tempnam.c libmysql/my_open.c libmysql/mf_casecnv.c libmysql/my_read.c \
---
>       libmysql/my_delete.c libmysql/my_open.c libmysql/mf_casecnv.c libmysql/my_read.c \

Does this mean by chance the gcc 3.1 treats this as an error what used to be a warning only in 2.9x ?

To me it looks like the linker has trouble with it somehow.  Compiles OK, but fails in linking with the 'unhandled FORM value: 14' error.

  Again, it looks as if the routines in my_tempnam.c are not referenced anywhere in the extension, so to me it looks as if it would be safe to remove the source file.

I've found this line through google: http://gcc.gnu.org/ml/gcc/2002-02/msg00965.html

Even better this one http://gcc.gnu.org/ml/gcc/2002-02/msg01071.html (one of the Follow-Ups)

  Is this something that could be caught when ./configure is run?  My concern is that ./configure checks for tempnam successfully eventhough it will not link.

  However, since this seems to be the behavior of AC_CHECK_FUNCS there might not be anything to do.

It seems that I have no problems with

Both are redhat linux,

Be sure to use the latest version of binutils that matches the gcc version you are using.

also works for Red Hat 7.3 and PHP 4.3.1:  

install:
mysql-3.23.54a-3.73.rpm
mysql-devel-3.23.54a-3.73.rpm

./configure --with-mysql=/usr

RedHat 9, standard instalation, PHP 4.3.1

Solution 

  --with-mysql=/path_to_base_mysql_directory

solve a problem

On Mandrake 9.1 none of the above methods seem to work. By installing libmysql12 and adding --with-mysql=/mysql_base_dir I just get "No header files in this location".

However, when putting --with-mysql=/usr I get:

...
ext/mysql/php_mysql.o(.text+0x1c74): In function `zif_mysql_create_db':
/home/lanttis/php-4.3.1/ext/mysql/php_mysql.c:1118: undefined reference to `mysql_create_db'

Any enlightment on the matter is deeply appreciated!
