recompiling php

I am trying to recompile php 5 with freetds so am using this : ./configure '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql=/root/mysql-standard-4.1.9-pc-linux-gnu-i686' '--with-mssql=/usr/local/freetds' Things seem ok so I do make and at the end of make I get this error: /usr/bin/ld:ext/mssql/php_mssql.lo: file format not recognized; treating as linker script /usr/bin/ld:ext/mssql/php_mssql.lo:2: syntax error collect2: ld returned 1 exit status make: *** [libphp5.la] Error 1 I then did make install and of course got the same error: /usr/bin/ld:ext/mssql/php_mssql.lo: file format not recognized; treating as linker script /usr/bin/ld:ext/mssql/php_mssql.lo:2: syntax error collect2: ld returned 1 exit status make: *** [libphp5.la] Error 1 I then do make clean. Of course, it doesn't seem to regenerate the libphp5.so so once I restart apache, and check out phpinfo, it shows the old configuration. What's wrong? Thanks!
