Hi, I am having a problem with running the globus-url-copy with the -udt option.
I installed the threaded version of the gridftp server using the nightly build of last week (make gridftp globus_gridftp_server-thr). I used gcc32 as the flavor. I then compiled gridftp with UDT with-flavor=gcc32dbgpthr. I ran the gridftp server without the "--protocol_stack udt_ref " option. Next I ran globus-url-copy as: globus-url-copy -vb -udt ftp://localhost:40300/dev/zero ftp://localhost:40300/dev/null and it gave me the following error: error: globus_ftp_client: the server responded with an error 500 500-Command failed : Setting data channel driver stack failed. 500-globus_xio: driver activation failed. 500-globus_extension_module: Couldn't dlopen libglobus_xio_udt_ref_driver_gcc32dbg.so in /home/zulfiimani/gridftp/INSTALL/lib (or LD_LIBRARY_PATH): libglobus_xio_udt_ref_driver_gcc32dbg.so: cannot open shared object file: No such file or directory 500- 500 End I have the libglobus_xio_udt_ref_driver_gcc32dbgpthr.so.* files in the GLOBUS_LOCATION/lib dir but not 'libglobus_xio_udt_ref_driver_gcc32dbg.so' because I have a threaded build. I even tried globus-url-copy -vb -dcstack udt_ref ftp://localhost:40300/dev/zero ftp://localhost:40300/dev/null but got the same error. Then I ran the gridftp server with the '--protocol_stack udt_ref' option and then executed the globus-url-copy without '-udt' option and it worked fine. Any inputs on this will be great. Thanks Zulfi
