    I have problems with php5-recode and php5-odbc. With both packages installed, odbc_execute() hangs up causing Segmentation Fault. I was using a simple script to test that:

    <?php
    #DSN "mydb" with a user and password "marin"
    $connect = odbc_connect("myaccess", "", "");

    # query the users table for name and surname
    $query = "SELECT * FROM FRT_NAME";

    # perform the query
    $result = odbc_exec($connect, $query);

    # fetch the data from the database
    while(odbc_fetch_row($result)){
                $name = odbc_result($result, 2);
            print(    "$name\n");
    }

    # close the connection
    odbc_close($connect);
    ?>

    After uninstalling php5-recode, the issue is solved.

    Hope this might help someone:

    I tried to compile php 4.3.2-RC2 (+some older versions) with recode AND imap (and gd+png+jpeg support, ldap, gettext, zlib .. but these are not interesting right now).

    Why? I needed to run Imp + Horde + Turba. Turba talks to LDAP directory (and LDAP uses utf-8 encoding which I need to convert to iso-8859-2), so I modified Turba to use 'recode' for charset conversions utf8<->iso8859-2.

    System: FreeBSD4.7+Apache 1.3.27+Ben SSL

    I either could not properly compile OR after compiling apache coredumped.

    Problem was: imap (libc-client) and recode (librecode) use the same function hash_lookup(). Therefore during loading libphp.so (and libraries it depended on) whole apache crashed. Without a word of what's going on.

    The problem is detectable by forcing static linking (in FreeBSD modify librecode.la and change
    library_names='librecode.so.0 librecode.so librecode.so'
    to
    library_names='librecode.a'

    Now during linking of php the linker complains of double definition of hash_lookup.

    Solution:

    -grab recode3.6 from ftp://ftp.gnu.org/pub/gnu/recode/
    -unpack, go to src, in files combine.c, hash.c, names.c, recode.c, testdump.c, html.c, hash.h replace hash_lookup() by hash_lookupX() [or invent some better name],
    compile recode (i had to do:

    setenv CFLAGS "-I/usr/local/include"
    setenv LDFLAGS "-L/usr/local/lib -lintl"
    ./configure --prefix=/usr/local/recode --exec-prefix=/usr/local/recode --without-included-gettext
    make
    make check
    make install

    (recode is installed to /usr/local/recode.You can change this and you can force static linking of recode, so that after building libphp.so this modified recode is no longer needed and can be deleted! )

    For some reason this recode needs to have externally defined
    int error;
    therefore we have to modify configure script +one .c php source file:

    1. modify configure script of php: find
    recode_format_table();
    and somewhere before start of main() add
    int error;

    so the result is:

    char *program_name;
    int error;
    int main() {
    recode_format_table();
    ; return 0; }

    (I modified both occurences of recode_format_table() in configure of php4.3.2rc2)

    2. run configure, should work ok (my another problem was with imap: though my c-client was compiled WITHOUT ssl, configure complained that it IS using ssl, so i had to edit configure once again and comment following lines:
    void mm_searched(void){}
    void mm_expunged(void){}
    // char ssl_onceonlyinit();  --- commented
    int main() {
    // ssl_onceonlyinit(); --- commented
    return 0;
    }

    Now configure was rather happy :-)

    for the record: I did
    ./configure --with-apxs=/usr/local/apache/bin/apxs --with-imap --enable-sysvsem --enable-sysvshm --with-sybase=/usr/local/freetds --with-gettext --with-ldap --with-zlib --with-recode=/usr/local/recode -with-gd=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local

    3. edit ext/recode/recode.c (or any other .c source file, add somewhere (e.g. at the end)
    int error;

    without it during linking 'error not defined' will be complained.

    4. do 'make' and php is yours :-)

    It took me 2 days.. so do not delete this note, someone might even find it useful and mail me his thanks :-]

    When compiling PHP into Apache as static module Apache configure will complain about an undefined symbol in librecode. You need recode-3.6 (e.g. on ftp://ftp.gnu.org/pub/gnu/recode/) to get rid of this error. It doesn't matter if you're compiling PHP as DSO.

    I see that the Recode (3.6) module is also incompatible with the MySQL module as well as the others noted in the "warning" note above.
