[Discuss-gnuradio] Link error in compilation of sample programs in /uhd/host/examples

[中城 智之]

Hi all,

I installed GnuRadio+UHD onto Ubuntu 12.10(64bit) and 13.04(64bit) by using 
build-gnuradio script in http://www.sbrac.org/files/build-gnuradio. No error 
message had been displayed in the installation. But a following link error 
message is shown when I compile sample c++ programs in /uhd/host/examples. 

******** error message ***********
>Scanning dependencies of target benchmark_rate
>[  5%] Building CXX object CMakeFiles/benchmark_rate.dir/benchmark_rate.cpp.o

*******************************

The compile procedure I use is following:
$ mkdir /uhd/host/examples/build
$ cd /uhd/host/examples/build
$ cmake ../
$ make

"ldconfig -p | grep boost_thread" returns

libboost_thread.so.1.49.0 (libc6,x86-64) => /usr/lib/libboost_thread.so.1.49.0
libboost_thread.so (libc6,x86-64) => /usr/lib/libboost_thread.so

therefore, I think that the path to boost library is recognized by operating 
system.

I would like you to inform me my mistake.
