Hi, I've talked about this with the Ceph dev's but I'm still struggling to get this working, so I hope there is somebody here who has a solution. I'm trying to rewrite phprados so it uses the new C++ API. I'm running into trouble with ioctx_create, this returns a ioctx object which I have to handle somehow in the PHP extension. My code can be found at http://www.widodh.nl/git/phprados.git in the librados2 branch. In PHP it looks like: $r = new Rados(); $r->init(); $r->conf_read_file('/etc/ceph/ceph.conf'); $r->connect(); $io = $r->ioctx_create('data'); $io->create('foo'); $r->shutdown(); With my current code I get a segfault with the following backtrace: 0x00ec1b86 in librados::IoCtx::create (this=0xbfffcb84, oid=..., exclusive=false) at librados.cc:2765 2765 return io_ctx_impl->client->create(*io_ctx_impl, obj, exclusive); (gdb) bt #0 0x00ec1b86 in librados::IoCtx::create (this=0xbfffcb84, oid=..., exclusive=false) at librados.cc:2765 #1 0x00e5ba7e in zim_RadosIoCtx_create (ht=1, return_value=0x8901cc0, return_value_ptr=0x0, this_ptr=0x8901b1c, return_value_used=0) at /home/wido/repos/phprados/ioctx.cc:64 #2 0x0836114a in ??

() #7 0x00646ce7 in __libc_start_main () from /lib/libc.so.6 #8 0x08066ce1 in _start () All the magic is done in rados.cc, in PHP_METHOD(Rados, ioctx_create) I register the returned ioctx object as a internal Zend object which I try to retrieve in ioctx.cc in PHP_METHOD(RadosIoCtx, create) I tried Googling around and see how other extension do this (since there is no documentation about this) and I seem to be in the right direction. Anyone here has an idea about how to solve this or what is going wrong here?
