    <p>The issue is hopefully pretty easy to resolve. When you do this...</p> <pre><code>set(ARMADILLO_LIBRARY "C:\\Program Files (x86)\\armadillo\\lib") set(ARMADILLO_INCLUDE_DIR "C:\\Program Files (x86)\\armadillo\\include") </code></pre> <p>you're effectively short-circuiting the <code>find_package(Armadillo 2.4.2 REQUIRED)</code> call, since it expects to have to do the work to find these paths. However, when <code>find_package</code> does the work, the variable <code>ARMADILLO_LIBRARY</code> gets set to the path to the library itself - not the path to the lib's directory.</p> <p>So the problem boils down to setting <code>ARMADILLO_LIBRARY</code> to the path to the lib's directory rather than the lib itself. This ultimately yields a linker error since the target <code>gmm</code> (added in src\mlpack\methods\gmm\CMakeLists.txt) links to <code>mlpack</code>, and <code>mlpack</code> has been set to link to <code>${ARMADILLO_LIBRARIES}</code>, which isn't set correctly.</p> <p>It turns out that <code>find_package(Armadillo ...)</code> already checks in <code>"$ENV{ProgramFiles}/Armadillo/lib"</code> and <code>"$ENV{ProgramFiles}/Armadillo/include"</code>, and I expect these resolve to <code>"C:\\Program Files (x86)\\armadillo\\lib"</code> and <code>"C:\\Program Files (x86)\\armadillo\\include"</code> on your machine.</p> <p>So to fix this, you should delete the lines setting <code>ARMADILLO_LIBRARY</code> and <code>ARMADILLO_INCLUDE_DIR</code>, and revert your change in src\mlpack\CMakeLists.txt (using <a href="http://www.cmake.org/cmake/help/v2.8.10/cmake.html#command%3alink_directories" rel="nofollow" title="CMake v2.8.10 documentation for &quot;link_directories&quot; command"><code>link_directories</code></a> is generally a bad idea anyway).</p> <p>After making these changes, you should delete at least your CMakeCache.txt (in the root of your build tree), or even your entire build tree before re-running CMake to avoid the possibility of using bad cached values from previous failed attempts.</p>

    1. COThx ! Tried this but I get this error: CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (message): Could NOT find Armadillo: Found unsuitable version "0.0.0", but required is at least "2.4.2" (found C:/Program Files (x86)/armadillo/lib/libarmadillo.dll) ... could it be that my installation of armadillo is messed up somehow ?

    2. COYes - probably. Are you using the same generator for MLPack as you did for compiling Armadillo? (MinGW?) It looks like the Armadillo lib is found correctly, but that it can't be read properly to find out its version.

    3. COI compiled armadillo using cmake then mingw32-make install. Now, I just performed it again without any changes to the cmake files (except deleting cache and tree) and things went smoothly (same as when I did it a couple of days ago). Now I am not sure where I messed up last time, because after that using cmake for mlpack seems now satisfied with armadillo (detect version 3.800.2). But now I have warnings about libxml2 ("targets may link only to libraries"). Did not compile libxml2, just downloaded binaries ... might come from that ? (btw, super thx for the help)

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.
