    <p>I was trying to install Boost on a linux machine(CentOs, Linux version 2.6.9-67.ELsmp). I followed with the instruction on Boost <a href="http://www.boost.org/doc/libs/1_49_0/more/getting_started/unix-variants.html#build-a-simple-program-using-boost">Getting Started</a> webpage. Downloaded and extracted the files, then I add prefix because I am not the root user.</p> <pre><code>./bootstrap.sh --prefix=/my_path/boost-1.49.0 ./b2 install </code></pre> <p>I go to /my_path/boost-1.49.0 and check there are /include/boost/ and /lib/ contain files there.</p> <p>also I set LD_LIBRARY_PATH to /my_path/boost-1.49.0/lib/.</p> <p>To test if I installed successfully, I compile the following code:</p> <p>main.cpp</p> <pre><code>#include &lt;boost/regex.hpp&gt; #include &lt;iostream&gt; #include &lt;string&gt; using namespace boost; using namespace std; int main(int argc, char *argv[]) { string line = "12345"; regex pattern("^123"); if (regex_match(line, pattern)) cout &lt;&lt; "match." &lt;&lt; endl; else cout &lt;&lt; "not match." &lt;&lt; endl; return 1; } </code></pre> <p>And compile by command:</p> <pre><code>g++ -v -I /my_path/boost-1.49.0/include/boost -L /my_path/boost-1.49.0/lib main.cpp -lboost_regex -o example </code></pre> <p>and generate following errors:</p> <pre><code>Reading specs from /usr/lib/gcc/x86_64-redhat-linux/3.4.6/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=x86_64-redhat-linux Thread model: posix gcc version 3.4.6 20060404 (Red Hat 3.4.6-9) /usr/libexec/gcc/x86_64-redhat-linux/3.4.6/cc1plus -quiet -v -I /my_path/boost-1.49.0/include/boost/ -D_GNU_SOURCE main.cpp -quiet -dumpbase main.cpp -mtune=k8 -auxbase main -version -o /tmp/ccW0ON8y.s ignoring nonexistent directory "/usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../x86_64-redhat-linux/include" #include "..." search starts here: #include &lt;...&gt; search starts here: /my_path/boost-1.49.0/include/boost/ /usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../include/c++/3.4.6 /usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../include/c++/3.4.6/x86_64-redhat-linux /usr/lib/gcc/x86_64-redhat-linux/3.4.6/../../../../include/c++/3.4.6/backward /usr/local/include /usr/lib/gcc/x86_64-redhat-linux/3.4.6/include /usr/include End of search list.

I have no idea of the error message above, really drive me mad. Any help is appreciated.</p> <p>Thanks for your patience and time.</p>

    1. COThe linker clearly does not include your installed boost libraries. Does it work to change `-L <your lib path>` to `-L<your lib path>`?

    2. CONope. In fact, my compile command did not have the space between -L and path. It's a typo in post, I'm sorry.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
