Thanks for your answers. And for the archives which helped me a lot.

At the end of the mail is the solution of the problem :

Hello,

I have several problems making freetds and php works together under AIX.
Has anyone successdully used this installation ?

At first, the apps and pools did not link OK. So I had to use the idea
of Fréderic le Guillou :
https://lists.ibiblio.org/sympa/arc/freetds/2004q3/016748.html

Now I have freetds which compiles and links OK. I can test the
connection to a SQL*Server DB with tsql.

I made this PHP test script :

<?php
$con = mssql_connect ("ip:port", "user", "****");
mssql_select_db ("db_name", $con);
$sql= "SELECT * FROM TABLE";
sleep(30);
$rs= mssql_query ($sql, $con);
echo "<html><head>/Title/</head><body>The field number one is:";
echo mssql_result ($rs, 0, 0);
echo " </body></html>";
mssql_close ($con);
?>

It works on the command line of php, but not from apache.
Why ?

Another problem : when I change the code of freetds, i can recompile and
install in /usr/local/freetds the libraries, but it seems php does not
use the libraries (I can delete them, php command line still works).

The explanation : freetds is linked inside the php lib and exec. So after recompiling freetds, I had to relink php.


My compilation directive :

UnixODBC :
./configure --prefix=/usr/local/unixODBC --enable-gui=no

Freetds :

./configure --prefix=/usr/local/freetds
--with-unixodbc=/usr/local/unixODBC --with-tdsver=8.0 --enable-dbmfix

PHP :
./configure --prefix=/usr/local/php
--with-apxs=/usr/local/apache/bin/apxs
--with-oci8=/oracle/oracle8/app/oracle/product/8.1.7
--with-mssql=/usr/local/freetds --without-mysql
--with-unixODBC=/usr/local/unixODBC

Thanks,

Joffrey Pannequin

Still the same architecture : freeTDS 0.62.4 / PHP 4.3.8 / AIX 4.3.3 .

I have been trying to locate the line in the source code that causes the problem, by debugging the program.
It appeared to me that it was due to a call to iconv_open.
This call works on the command line.
But not when called from the php module (libphp4.so) for Apache.
--disable-libiconv
So I launched the configure with the following options :

./configure --prefix=/usr/local/freetds --disable-libiconv --without-unixodbc --with-tdsver=8.0 --enable-dbmfix --disable-shared

--disable-libiconv is to use the iconv coded inside freetds instead of the one from AIX or gcc or whatever (see https://lists.ibiblio.org/sympa/arc/freetds/2004q1/015431.html and the replies).
--disable-shared is to use static library instead of shared ones. It means freetds will be inside php and not as a separate module (so bigger). But it avoided me segmentation fault... I guess it is due to the way AIX deals with shared libraries.

And now I can finally see my test page in my browser (well after the make && make install && [configure,make,make install for php as well]).


Note : I have to disable odbc by hand (in the Makefile) or I missed something (maybe --without-odbc).
