Sybase and PHP

We have been using sybase with PHP4 and now are looking to move to PHP5. I ran into an installation problem with PHP5 and starting looking at the bug reports and can't tell for sure whether sybase is being supported any longer. I was working with PHP5 source rpm on Fedora 6 when I ran into a problem with recompiling it (rpmbuild -ba). I really couldn't make much of the error. php-5.1.6-3 Building from rpm source I get the following errors. with standard Fedora6 src I added the following line to the --with-sybase-ct=/opt/sybase/OCS-15_0 \ Building from rpm source I get the following errors. ----- screen error ------ checking for string.h... (cached) yes checking for char... yes checking size of char... configure: error: cannot compute sizeof (char), 77 See `config.log' for more details. error: Bad exit status from /var/tmp/rpm-tmp.17076 (%build) ---------------------------------- partial output from config logs config.log before this it indicated that it was in confdefs.h ------------------------------- #define SIZEOF_LONG 4 #define SIZEOF_LONG 4 #define SIZEOF_LONG 4 #define SIZEOF_LONG 4 #define SIZEOF_LONG_LONG 8 #define SIZEOF_LONG_LONG 8 #define SIZEOF_LONG_LONG_INT 8 #define SIZEOF_PTRDIFF_T 4 #define SIZEOF_SHORT 2 #define SIZEOF_SHORT 2 #define SIZEOF_SIZE_T 4 #define SIZEOF_SSIZE_T 4 #define STDC_HEADERS 1 #define STDC_HEADERS 1 #define TIME_WITH_SYS_TIME 1 #define UCD_SNMP_HACK 1 #define UNDEF_THREADS_HACK #define USE_GD_IMGSTRTTF 1 #define USE_GD_IMGSTRTTF 1 #define YYTEXT_POINTER 1 #define _GNU_SOURCE 1 configure: exit 1
