Gr-air will not link correctly on 64 bit Ubuntu 12.04 says incompatible with

GNU Radio

Hello discuss-gnuradio list this is Lee M,

Making the gr-air application on a 64 bit Ubuntu 12.04 computer stops
with a linking error.

I found the Wiki instruction about editing /etc/ld.so.conf

The wiki entry is:
http://gnuradio.org/redmine/projects/gnuradio/wiki/UbuntuInstall#Broken-libtool-on-Debian-and-Ubuntu

It seems to me that /etc/ld.so.conf is a list of directories that the
linker “ld” is being configured to vist, yes?

I tried various versions of adding the text “/usr/local/lib” to
ld.so.conf, I ran ldconfig. The make error stayed the same.

Here is the text of the linking error:

cat errortext.txt

Here’s what I just did:

git clone GitHub - bistromath/gr-air-modes: Gnuradio Mode-S/ADS-B radio
cd gr-air-modes
mkdir build
cd build
cmake …
make

Worked just fine.

Run the file command on CMakeFiles/air_modes.dir/modes_crc.cc.o

Perhaps there is a version mismatch betwenn 32 and 64 bit ?
