    <p>I am linking a (Python extension) library that embeds the Matlab engine with the following command (generated using cmake)</p> <pre><code>c++ -mmacosx-version-min=10.6 -bundle -headerpad_max_install_names -o library.so library.o /Applications/MATLAB_R2009b.app/bin/maci64/libeng.dylib /Applications/MATLAB_R2009b.app/bin/maci64/libmx.dylib -framework Python </code></pre> <p>resulting in </p> <pre><code>$ otool -L library.so library.so: @loader_path/libeng.dylib (compatibility version 0.0.0, current version 0.0.0) @loader_path/libmx.dylib (compatibility version 0.0.0, current version 0.0.0) /System/Library/Frameworks/Python.framework/Versions/2.6/Python (compatibility version 2.6.0, current version 2.6.1) /opt/local/lib/gcc44/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.13.0) /opt/local/lib/gcc44/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0) </code></pre> <p>However, when I try to use the library, I get an error message:</p> <pre><code>ImportError: dlopen(./library.so, 2): Library not loaded: @loader_path/libmex.dylib Referenced from: ./library.so Reason: image not found </code></pre> <p>I believe the problem stems from the fact that the linker includes the matlab dylib files in the form <code>@loader_path/libeng.dylib</code> rather than using the full path, even though I give the full path to <code>g++</code>. How can I force the linker to use the full path?</p> <p>I know one solution is to use </p> <pre><code>export DYLD_LIBRARY_PATH=/Applications/MATLAB_R2009b.app/bin/maci64:$DYLD_LIBRARY_PATH </code></pre> <p>which is where those library files reside, but I'd like to avoid that as it causes some other problems. </p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
