I have a 64 bit red hat linux (also 64 bit) box.
1) I downloaded boost from
boost_1_34_1.tar.bz2 <http://downloads.sourceforge.net/boost/boost_1_34_1.tar.bz2?modtime=1185241 108&big_mirror=0>
2) Unizipped and installed it (./configure , make install ) everything worked fine.
Questions:
[Well, neither question is actually a question about Boost, but anyway]
1) How do I check if I now have the 64 bit version of boost?
file <any-library-file> should produce output such as: <library>: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), stripped You can also use readelf -h <any-library-file>
2) I see that all libraries were put into /usr/local/lib and I can compile my hello world code with the following command.
* $ g++ hello.cpp -lboost_thread-gcc41-mt-1_34_1
but when I try to run the created a.out file I get a file not found error msg.
* $ ./a.out
* ./a.out: error while loading shared libraries: libboost_thread-gcc41-mt-1_34_1.so.1.34.1: cannot open shared object file: No such file or directory
I did an ldd and this is the output.
$ ldd a.out
libboost_thread-gcc41-mt-1_34_1.so.1.34.1 => not found
You should add /usr/local/lib to LD_LIBRARY_PATH environment variable. - Volodya
