Hi Siyu,

this, frankly, isn't the perfect mailing list for this topic. I've taken the discuss-gnuradio list into CC:; please sign up for that under [1] and continue discussing there!

I'll quickly address the things you say below:

the ldconfig message is probably not a problem, just a misconfiguration of something on your system. You can ignore it.

The -msse2 flag was added to GCC3.1 somewhen in May 2002. If you're building for x86 or x86_64 and your compiler doesn't know that, you either have a very strange compiler, or a very old one, that you simply can't use anymore.

If you're not building for x86, you might want to tell us.

Best regards,

Hi all,

Sorry for bother you. But I got two strange errors while I compile the code, downloaded from https://github.com/bastibl/gr-ieee802-11.

1. in the last step of installing gr-foo . after i type "sudo ldconfig".

i got a message like:

ldconfig: /usr/lib/libstdc++.so.6.0.20-gdb.py is not an ELF file - it has the wrong magic bytes at the start.

2. in the installation of gr-ieee802-11 part. i got a message:

[  9%] Building CXX object lib/CMakeFiles/gnuradio-ieee802_11.dir/moving_average_cc_impl.cc.o

How to solve it ? Many thanks.
