I am unable to compile PHP 4.1.0 with libiodbc 3.0.5 

Here is what I did: 

____________________________________________________________

$ ls 
libiodbc-3.0.5.tar.gz 
php-4.1.0.tar.gz 

$ tar xzf libiodbc-3.0.5.tar.gz 
$ cd libiodbc-3.0.5 
$ ./configure --prefix=/home/kan/tmp --disable-shared --disable-gui 
..... 
$ gmake 
..... 
$ gmake install 
..... 

$cd .. 

$ tar xzf php-4.1.0.tar.gz 
$ cd php-4.1.0 
$ ./configure --with-apxs=/usr/local/apache/bin/apxs --with-iodbc=/home/kan/tmp --without-mysql --without-xml 
.... 

$ make 
..... 
Making all in .

I am supposing that libZend.la library contains libiodbc.a library functions. And in the last compile command both libZend and libiodbc are presents. So conflict with multiply definition somewhere here.

Thanks,
