Hmm.  Small thing, you didn’t want to copy that system DLL to the gr-python dir, the gr-python DLL is a custom build.  But for the moment let’s not worry about that.

Let’s try this as a test... copy the pyd file to /bin folder and see if the error change.

  If not, then reopen dependency checker and drill down into the gnuradio-osmosdr and see if any of the device  driver DLLs or other reference is missing.

Past that I am puzzled.  But I’ll have a bit of time tomorrow eve to look a bit closer.

The System32 dll is also being loaded here as well.

I don't have a run_gr_d.bat file so I can't run that test for you.

I moved the Python27.dll file from C:\Windows\System32 to my python install directory which is C:\Python27. I also copied it to the GR python locations as well.

However, the same issue persists. Here is the output of your command list after the "fix" was applied.

So evidently even though the dll is gone from System32 the issue still persists.

Thoughts? Again I appreciate your help.

Subject: Re: [Discuss-gnuradio] GNURadio Windows Errors with OsmoSDR

OK, I think a clue here is that a python dll is installed in System32.
Windows will always check System32 regardless of the PATH, so something there might be causing some misdirection.

Try this... run the "run_gr.bat" file and once in, run python by simply entering "python"

Then enter;
import subprocess
print subprocess.check_call("where python27.dll") import sys
print(sys.executable)
for p in sys.path:
import numpy
import gnuradio
import osmosdr

This will get us some basic path info and we can see where it breaks.
THEN repeat, but before running the python command enter "cd ..\gr-python27" and see if the results are different.
Finally, repeat the above but using the run_gr_d.bat instead.  That runs the debug version of python, and it's less likely you have a debug version installed on your machine, so if _d works that's just further confirmation.

My suspicion is that the above will show that that the DLL from
System32 is being loaded in the first case, but not in the others.  If so, then the solution is to remove python27.dll from System32 (which belongs to a different python installation) and move it to wherever you have a 64-bit install of python27 (since it at least appears to be a 64 bit Dll) in the same folder as python.exe.  If you have more than, then copy it to each one that doesn't have one of it's own.

If none of this worked, please send screen shots back.

I don't believe many Python distros are still installing to System32 for exactly this reason.
