    <p>I'm new to autom4te, and I'm trying to use autoconf/automake to build and link a C++ program on multiple architectures. Complicating the linking is the fact that the project requires boost (filesystem, system, program_options).</p> <p>I'm using boost.m4 (from <a href="http://github.com/tsuna/boost.m4/tree/" rel="nofollow noreferrer">http://github.com/tsuna/boost.m4/tree/</a>), and it seems to locate all the libraries and headers successfully.</p> <p>Unfortunately, linking still fails, leaving me confused.</p> <p>These are the relevant lines of <code>configure.ac</code>:</p> <pre><code>AC_CONFIG_MACRO_DIR([m4]) # ... AC_PROG_CXX AC_PROG_LIBTOOL # ... BOOST_REQUIRE([1.41.0]) BOOST_FILESYSTEM BOOST_SYSTEM BOOST_PROGRAM_OPTIONS # ... </code></pre> <p>And in <code>src/Makefile.am</code>:</p> <pre><code>bin_PROGRAMS = phenomatrix phenomatrix_CXXFLAGS = $(BOOST_CPPFLAGS) phenomatrix_LDFLAGS = $(BOOST_LDFLAGS) $(BOOST_SYSTEM_LDFLAGS) $(BOOST_FILESYSTEM_LDFLAGS) $(BOOST_PROGRAM_OPTIONS_LDFLAGS) # $(BOOST_SYSTEM_LIB) $(BOOST_PROGRAM_OPTIONS_LIB) $(BOOST_FILESYSTEM_LIB) phenomatrix_LIBS = $(BOOST_SYSTEM_LIBS) $(BOOST_FILESYSTEM_LIBS) $(BOOST_PROGRAM_OPTIONS_LIBS) phenomatrix_SOURCES = adjacency_list.cpp distance.cpp genephene.cpp knearest.cpp marshall.cpp oracle.cpp type_shield.cpp avgmindist.cpp euclidean.cpp hypergeometric.cpp main.cpp mindist.cpp partialbayes.cpp utilities.cpp </code></pre> <p>These give no errors, and it even manages to find the libraries and headers:</p> <pre><code>checking for Boost headers version &gt;= 104100... yes checking for Boost's header version... 1_41 checking for the toolset name used by Boost for g++... gcc44 -gcc checking boost/system/error_code.hpp usability... yes checking boost/system/error_code.hpp presence... yes checking for boost/system/error_code.hpp... yes checking for the Boost system library... yes checking boost/filesystem/path.hpp usability... yes checking boost/filesystem/path.hpp presence... yes checking for boost/filesystem/path.hpp... yes checking for the Boost filesystem library... yes checking for boost/system/error_code.hpp... (cached) yes checking for the Boost system library... (cached) yes checking boost/program_options.hpp usability... yes checking boost/program_options.hpp presence... yes checking for boost/program_options.hpp... yes checking for the Boost program_options library... yes </code></pre> <p>But then, when I run <code>make</code>, I get errors:</p> <pre><code>libtool: link: g++ -g -O2 -o phenomatrix phenomatrix-adjacency_list.o phenomatrix-distance.o phenomatrix-genephene.o phenomatrix-knearest.o phenomatrix-marshall.o phenomatrix-oracle.o phenomatrix-type_shield.o phenomatrix-avgmindist.o phenomatrix-euclidean.o phenomatrix-hypergeometric.o phenomatrix-main.o phenomatrix-mindist.o phenomatrix-partialbayes.o phenomatrix-utilities.o -L/usr/local/lib -Wl,-rpath -Wl,/usr/local/lib phenomatrix-adjacency_list.o: In function `__static_initialization_and_destruction_0': /usr/local/include/boost/system/error_code.hpp:208: undefined reference to `boost::system::get_system_category()' /usr/local/include/boost/system/error_code.hpp:209: undefined reference to `boost::system::get_generic_category()' /usr/local/include/boost/system/error_code.hpp:214: undefined reference to `boost::system::get_generic_category()' /usr/local/include/boost/system/error_code.hpp:215: undefined reference to `boost::system::get_generic_category()' /usr/local/include/boost/system/error_code.hpp:216: undefined reference to `boost::system::get_system_category()' </code></pre> <p>which repeat ad nauseum.</p> <p>I'm not even sure how to go about testing to see if it's including the right directories. Yes, I understand that there's a <code>-t</code> flag on g++, but I don't exactly know how to pass that (from within autom4te).</p> <p>I gather this has something to do with multiple versions of the boost libs and headers on the same machine, and there's not much I can do about that.</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).
