Problems with iconv on AIX 5.3 and 6.1 - maybe a bug

I think it is a bug, but it might also be a misunderstanding. Background: I am trying to convert Joomla 1.0.X to 1.5.X and ran into problems with the conversion of the database that is done during the migration. I started out by doing several of the tests/samples in the php manuals, but always got blank results. I tried changing the php.ini settings: [iconv] iconv.input_encoding = ISO8859-1 iconv.internal_encoding = ISO8859-1 iconv.output_encoding = ISO8859-1 and I dont think it is really necessary - as the iconv command interface also accepts ISO-8859-1 as an argument. Initially I was confused by the information provided by phpinfo() from Joomla 1.0.X SysInfo tab: iconv iconv support enabled iconv implementation unknown iconv library version unknown Only when I looked in iconv.c did I find where the "unknown" string was coming from: #ifdef PHP_ICONV_IMPL

        REGISTER_STRING_CONSTANT("ICONV_IMPL", PHP_ICONV_IMPL, CONST_CS | CONST_PERSISTENT);

#elif HAVE_LIBICONV

        REGISTER_STRING_CONSTANT("ICONV_IMPL", "libiconv", CONST_CS | CONST_PERSISTENT);

#elif defined(NETWARE)

        REGISTER_STRING_CONSTANT("ICONV_IMPL", "Novell", CONST_CS | CONST_PERSISTENT);

#else

        REGISTER_STRING_CONSTANT("ICONV_IMPL", "unknown", CONST_CS | CONST_PERSISTENT);

#endif

        REGISTER_STRING_CONSTANT("ICONV_VERSION", version, CONST_CS | CONST_PERSISTENT);

It seems my system is being configured, but under #else - "unknown". I did some digging in configure. Once configures finds iconv (PHP version 5.2.13 line numbers!) Please note the bold lines: *configure:45884: checking for iconv support configure:45947: checking for iconv* configure:45975: xlc -o conftest -L/usr/local/ssl/lib -L/usr/local/lib -L/usr/lib -L/usr/local/mysql/lib -blibpat h:/usr/local/lib:/usr/lib:/usr/local/ssl/lib:/usr/local/mysql/lib -R/usr/local/lib -L/usr/local/lib conftest.c -lf reetype -lpng -lz -ljpeg -lcurl -lz -lrt -lm -lxml2 -liconv -lm -lcurl -lxml2 -liconv -lm 1>&5 ld: 0706-027 The -R /usr/local/lib flag is ignored. *configure:46563: checking if iconv is glibc's* configure:46572: xlc -o conftest -I/usr/include -L/usr/local/ssl/lib -L/usr/local/lib -L/usr/lib -L/usr/local/mysq l/lib -L/usr/lib -blibpath:/usr/local/lib:/usr/lib:/usr/local/ssl/lib:/usr/local/mysql/lib -R/usr/local/lib -L/us r/local/lib conftest.c -lfreetype -lpng -lz -ljpeg -lcurl -lz -lrt -lm -lxml2 -liconv -lm -lcurl -lxml2 -liconv - lm 1>&5 "configure", line 46566.10: 1506-296 (S) #include file <gnu/libc-version.h> not found. configure: failed program was: #line 46565 "configure" #include "confdefs.h" #include <gnu/libc-version.h> int main() { gnu_get_libc_version(); ; return 0; } *configure:46590: checking if using GNU libiconv* configure:46610: xlc -o conftest -I/usr/include -L/usr/local/ssl/lib -L/usr/local/lib -L/usr/lib -L/usr/local/mysq l/lib -liconv -L/usr/lib -blibpath:/usr/local/lib:/usr/lib:/usr/local/ssl/lib:/usr/local/mysql/lib -R/usr/local/l ib -L/usr/local/lib conftest.c -lfreetype -lpng -lz -ljpeg -lcurl -lz -lrt -lm -lxml2 -liconv -lm -lcurl -lxml2 - liconv -lm 1>&5 "configure", line 46604.22: 1506-045 (S) Undeclared identifier _libiconv_version. configure: failed program was: #line 46600 "configure" #include "confdefs.h" #include </usr/include/iconv.h> int main() {

I felt that it "should" work with *libiconv *as it's variable. In configure, as a hack to test, I added the lines: if { (eval echo configure:45975: \"$ac_link\") 1>&5; (eval $ac_link) 2>&5; } && test -s conftest${ac_exeext}; then rm -rf conftest* eval "ac_cv_func_iconv=yes"

else echo "configure: failed program was:" >&5 cat conftest.$ac_ext >&5 rm -rf conftest* eval "ac_cv_func_iconv=no" fi and farther below: *echo "MAMF TESTING:host:" $host_alias "iconv_impl_name is:" $iconv_impl_name >&5*

    case "$iconv_impl_name" in
*      aix_libiconv | gnu_libiconv )*

make: 1254-004 The error code from the last command is 1. So I modified iconv.c to read: /* {{{ PHP_MINIT_FUNCTION */ PHP_MINIT_FUNCTION(miconv) {

======== To be continued. The sapi/cli/php5 is not being created now. Will be updated with changes in the failed make test output once I figure what has gone wrong. :(
