    copied!<p>I have two versions of GCC installed on my system 4.6.2 and 4.7.0. I am running Fedora Core 16.</p> <p>4.6.2 is installed in <code>/usr/bin</code> and 4.7.0 is installed in <code>/home/nerozehl/local/bin</code>. The libraries and runtime for C++ are also compiled and installed in <code>/home/nerozehl/local/lib</code> and <code>/home/nerozehl/local/lib64</code>.</p> <p>I also have two versions of Boost installed, with libraries in <code>/usr/lib64</code> and <code>/home/nerozehl/local/lib</code>. (Boost 1.47.0 and 1.49.0, respectively)</p> <p>The problem I am having is that g++ / ld are linking against the default libraries, and not the newer ones in <code>/home/nerozehl/local</code>. I am using <code>configure</code> to generate Makefiles, and am calling it this way:</p> <pre><code>CXX=g++47 CXXFLAGS="-g -O0 -pg" LDFLAGS="-L/home/nerozehl/local/lib" ./configure --prefix=/home/nerozehl/local </code></pre> <p>Where <code>g++47</code> resides in the <code>/home/nerozehl/local/bin</code> (in my <code>$PATH</code>).</p> <p>When I compile, everything is fine, and the newer headers are used, but when I check what it was linked against:</p> <pre><code>ldd source/noes linux-vdso.so.1 =&gt; (0x00007fffebfff000) libboost_filesystem-mt.so.1.47.0 =&gt; /usr/lib64/libboost_filesystem-mt.so.1.47.0 (0x0000003c6a800000) libboost_system-mt.so.1.47.0 =&gt; /usr/lib64/libboost_system-mt.so.1.47.0 (0x0000003c6a400000) libboost_program_options-mt.so.1.47.0 =&gt; /usr/lib64/libboost_program_options-mt.so.1.47.0 (0x0000003c6ac00000) libstdc++.so.6 =&gt; /usr/lib64/libstdc++.so.6 (0x0000003c6dc00000) libm.so.6 =&gt; /lib64/libm.so.6 (0x0000003c68c00000) libgcc_s.so.1 =&gt; /lib64/libgcc_s.so.1 (0x0000003c69c00000) libc.so.6 =&gt; /lib64/libc.so.6 (0x0000003c68800000) libpthread.so.0 =&gt; /lib64/libpthread.so.0 (0x0000003c69000000) librt.so.1 =&gt; /lib64/librt.so.1 (0x0000003c69800000) /lib64/ld-linux-x86-64.so.2 (0x0000003c68400000) </code></pre> <p>For the life of me I can't figure out how to force g++ / ld / configure to use my newer libraries. Any help would be appreciated.</p>
