    <p>Many people appear to have encountered this problem. The GNU website strongly recommends running </p> <pre><code>./contrib/download_prerequisites </code></pre> <p>in the source directory to avoid problems with linking MPC, MPFR and GMP. The following link contains the instructions I've followed: <a href="http://gcc.gnu.org/wiki/InstallingGCC" rel="nofollow">http://gcc.gnu.org/wiki/InstallingGCC</a> which I've listed here:</p> <pre><code>tar xzf gcc-4.8.1.tar.gz cd gcc-4.8.1 ./contrib/download_prerequisites cd .. mkdir objdir cd objdir $PWD/../gcc-4.8.1/configure --prefix=$HOME/gcc-4.8.1-install make make install </code></pre> <p>The FAQ at this url: <a href="http://gcc.gnu.org/wiki/FAQ#configure_suffix" rel="nofollow">http://gcc.gnu.org/wiki/FAQ#configure_suffix</a> claims that the compilation will have no problem finding MPC related files so long as they are located in a subdirectory of the gcc-4.8.1 source directory. Running </p> <p>./contrib/downlaod_prerequisites</p> <p>downloads MPC in the correct location, yet I still get this error after running make: </p> <pre><code>checking for x86_64-unknown-linux-gnu-gcc... /home/xxxx/gcc-4.8.1-build/./gcc/xgcc -B/home/xxxx/gcc-4.8.1-build/./gcc/ -B/home/xxxx/gcc-4.8.1-install/x86_64-unknown-linux-gnu/bin/ -B/home/xxxx/gcc-4.8.1-install/x86_64-unknown-linux-gnu/lib/ -isystem /home/xxxx/gcc-4.8.1-install/x86_64-unknown-linux-gnu/include -isystem /home/xxxx/gcc-4.8.1-install/x86_64-unknown-linux-gnu/sys-include checking for suffix of object files... configure: error: in `/home/xxxx/gcc-4.8.1-build/x86_64-unknown-linux-gnu/libgcc': configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details. </code></pre> <p>Opening <strong>/home/xxxx/gcc-4.8.1-build/x86_64-unknown-linux-gnu/libgcc/config.log</strong> reveals the following error:</p> <pre><code>/home/mgiamou/gcc-4.8.1-build/./gcc/cc1: error while loading shared libraries: libmpc.so.2: cannot open shared object file: No such file or directory </code></pre> <p>The GNU FAQs (<a href="http://gcc.gnu.org/wiki/FAQ#configure_suffix" rel="nofollow">http://gcc.gnu.org/wiki/FAQ#configure_suffix</a>) say that this error is symptomatic of not having properly installed MPC. Any help would be much appreciated.</p>

    1. CODid you exactly follow the instructions from step 1, or did you first try something else and only then run the contrib script? Can you look through the logs for the command line that created cc1 (should contain "-o cc1")?

    2. COI followed the instructions sequentially; I didn't try anything beforehand. The command line that creates cc1 is very large, anything I should be looking for in particular?

    3. COAny -L flag related to MPC. Then check that there is indeed a libmpc.a in that directory, and no libmpc.so. Then check that there isn't a libmpc.so in any of the other paths pointed to by a -L flag.

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.
