Hi,

I had a problem executing dx program in my computer after installing
opendx-4.2.0.

The make install work fine, and also calling dx programs works as well.

The "Welcome" and "Data Explorer" windows opens correctly.
But, when I tried to start the suggested tutorial:

===> Click on "Edit Visual Programs ..."	("Net File Selection" opens)
======>  Edit Filter line: to /usr/local/dx/samples/tutorial/*.net  [filter]
======>  Select: Selection /usr/local/dx/samples/tutorial/example1.net [ok]

I got the following error message:

------------------------------------------------------------------------------
Error: Unable to connect to dxexec.

The xterm window reports (at the same time) the additional message:

bash-2.05b$ dx
_dxl_ReadPortNumber: Bad file descriptor
timeout waiting for response from DX
select: Bad file descriptor

------------------------------------------------------------------------------

I found the program dxexec in directory /usr/local/dx/bin_freebsd/dxexec

and run it. It seems to work properly.




I'm using FreeBSD 4.8 and the usual installation port.

I'll sent a copy of the final information about "make install" of opendx.
