RE: [Discuss-gnuradio] Wrong number of arguments for overloaded function 'gr_top_block_sptr_connect'.

[Johan Mussche]

I have followed the advise, but it did not work. I am working on Ubuntu 9.04 
and use gnuradio 3.2.2.
The error only occurs when I use the SSRP. Other flow-graphs create no errors.

Are there any other ideas about the cause.

Regards,
Johan

I have seen this error before on a fedora 11 system, reproducible too. If you 
make clean, make, and make install your from your source, and try again, it 
should go away. I have no idea why.

Also, I recommend using gnuradio 3.2  (or from the master) which comes with a 
way-newer version of grc.

Hello everyone,

I am trying to use a SSRP with GNU-radio. In the past, with version 3.1 of 
gnuradio and GRC 0.69, the SSRP worked.

Now I am using the latest version of GNU-radio from the svn trunk in 
combination with swig 1.3.36 and python 2.6.
I have installed the ssrp-files into gnuradio and added the SSRP-block to GRC. 
Loading the firmware into the SSRP is no problem but
when I want to run the flow-graph I get the following error:

I have also tried to to use the old GRC (0.69) but that gives the same error, 
so it has nothing to do with GRC.

Can anyone tell me the cause of this error. Is it because of the newer version 
of swig or gnuradio?

Best regards,

Johan
