[Discuss-gnuradio] undefined symbol: _Z20gr_make_io_signatureiii
Hey! I installed gnuradio like described here: http://gnuradio.org/trac/wiki/UbuntuInstall and everything worked fine. Now I try to run the benchmark and i get this: sudo ./usrp_fft.py Traceback (most recent call last): File ./usrp_fft.py, line 23, in module from gnuradio import gr, gru File /usr/local/lib/python2.5/site-packages/gnuradio/gr/__init__.py, line 27, in module from gnuradio_swig_python import * File /usr/local/lib/python2.5/site-packages/gnuradio/gr/gnuradio_swig_python.py, line 23, in module from gnuradio_swig_py_runtime import * File /usr/local/lib/python2.5/site-packages/gnuradio/gr/gnuradio_swig_py_runtime.py, line 6, in module import _gnuradio_swig_py_runtime ImportError: /usr/local/lib/python2.5/site-packages/gnuradio/gr/_gnuradio_swig_py_runtime.so: undefined symbol: _Z20gr_make_io_signatureiii I tried to find answers in the history here but was not successful, can anybody give me a hint? I get the same error with usrp_benchmark_usb.py thanks! Tomek -- Ist Ihr Browser Vista-kompatibel?

[Discuss-gnuradio] USRP Benchmark fails with 32MB/sec
Hey! I installed the software and all tests ran OK. I have an USRP and I ran the benchmark test_usrp_benchmark.py and almost every time I start the script I get another result. Sometimes 4MB sometimes 16MB but never 32MB. I´m using an DELL Inspiron 8100 with 512 RAM, 866MHZ Mobile PIII and USB 2.0 PCMCIA could this be the problem?

AW: [Discuss-gnuradio] Why is Barker Spreading difficult to usrp?
Hello! I´m really new to gnu-radio. I installed the 3.0.4 version on my Ubuntu system finally and now I need some ideas, here is what I want to do: I want to use the USRP to sniff everything going on between 2 WLAN-PCMCIA Laptops on 2,4GH. How do I do that..? Does GNU Radio give me any tools making it possible to visualize this in any way? Thx!

[Discuss-gnuradio] gnuradio_swig_python.cc:133570: error: invalid conversion from `const char*' to `char*'
Hey! need some more help with gnuradio on cygwin. I´m still following the Installing GNU Radio with Cygwin and the only problem so war war that i couldn´t get wxPython to work because the patch -p0 -b -i config.patch command is always telling me: $ patch -p0 -b -i config.patch patch: Only garbage was found in the patch input.. but the instruction sais wxPython is not necessary so I went on. Everything worked until i run make it tells me: f::_attack_rate' will be initialized after ../../../../gnuradio-core/src/lib/general/gri_agc2_ff.h:82: warning: `float gr i_agc2_ff::_decay_rate' ../../../../gnuradio-core/src/lib/general/gri_agc2_ff.h:40: warning: when init ialized here gnuradio_swig_python.cc: In function `void SWIG_Python_FixMethods(PyMethodDef*, swig_const_info*, swig_type_info**, swig_type_info**)': gnuradio_swig_python.cc:133570: error: invalid conversion from `const char*' to `char*' make[6]: *** [gnuradio_swig_python.lo] Error 1 make[6]: Leaving directory `/usr/src/gnuradio-3.0.4/gnuradio-core/src/lib/swig' make[5]: *** [all] Error 2 make[5]: Leaving directory `/usr/src/gnuradio-3.0.4/gnuradio-core/src/lib/swig' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/usr/src/gnuradio-3.0.4/gnuradio-core/src/lib' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/usr/src/gnuradio-3.0.4/gnuradio-core/src' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/src/gnuradio-3.0.4/gnuradio-core' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/gnuradio-3.0.4' make: *** [all] Error 2 can anyone give me a hint what to do and how to fix this? Could it be that i have not installed wxPython correctly like i mentionen above? thx! tomek -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS.

[Discuss-gnuradio] Problem: Package fftw3f was not found in the pkg-config
Hello! I´m new to GNU Radio. I´m working on a project now and trying to get it to compile. I´m using cygwin and followed the Installing GNU Radio with Cygwin instruction step-by-step. The only problem i hade on the way was with wxPython because i tried the 2.8.6.0 and the instructions are for version 2.8.0.1 and i am missing the config.patch file in the 2.8.6.0 version. Anyhow...i tried it despide my failure with wxPython because the instruction sais it is not necessary. Everything else was fine and worked. Now i tried to configure gnuradio 3.0.4 and i get the following message: checking for fftw = 3.0... Package fftw3f was not found in the pkg-config search path. Perhaps you should add the directory containing 'fftw3f.pc' to the PKG_CONFIG_PATH enviroment variable No package 'fftw3f' found configure: error: Libary requirements (fftw3f = 3.0) not met; consider adjusting the PKG_CONFIG_PATH enviroment variable if you libaries are in a nonstander prefix so pkg-config can find tham. swhat do i have to do? edit the PKR_CONFIG_PATH? I googled and found out it FC5 could be the answer but FC5 installatin isw not explained in the cygwin instruction (http://gnuradio.org/trac/wiki/FC5Install) so anybody can give me a hint? thx!
