    text
    copied!<p>Performed the following steps:</p> <p>I have a working cross development system for gumstix overo (arm) running on Ubuntu 9.04. Now I want to use boost. So I tried to crosscompile boost like follows:</p> <p>1.) Download boost 1.49</p> <p>2.) build boost build system with: tools/build/v2/ bootstrap.sh</p> <p>3.) Modified user-config.jam to: # Configure gcc (default version). using gcc : arm : /opt/Gumstix.Toolchain/overo-oe/bin/arm-angstrom-linux-gnueabi-gcc ;</p> <p>4.) Compile boost by calling: ~/boost_1_49_0$ ./tools/build/v2/b2 toolset=gcc-arm stage</p> <p>5.) Resulting in: ...failed updating 56 targets... ...skipped 6 targets... ...updated 783 targets...</p> <p>-> I do not know what failed but within stage/libs all libs are existing.</p> <p>Setup simple C project:</p> <pre><code>#include &lt;boost/asio.hpp&gt; boost::asio::io_service io_service; ... No other boost stuff here. </code></pre> <p>Now link against created libboost_system.a library.</p> <p>Results in:</p> <pre><code>make all Building target: ChecksumTest_arm-omap3503 Invoking: GCC C++ Linker arm-angstrom-linux-gnuabi-g++ -L../../../../../../../Binary/Lib -L/home/Workspace /Projekte/boost/boost_1_49_0/stage/lib -o "ChecksumTest_arm-omap3503" ./src/ChecksumTest.o -lTools_arm-omap3503 -lboost_system -lrt ./src/ChecksumTest.o: In function `global constructors keyed to _Z8checkCrcRKN5Tools8Checksum4TypeERKj': ChecksumTest.cpp:(.text+0x20): undefined reference to `boost::system::get_system_category()' ChecksumTest.cpp:(.text+0x2c): undefined reference to `boost::system::get_generic_category()' ChecksumTest.cpp:(.text+0x38): undefined reference to `boost::system::get_generic_category()' ChecksumTest.cpp:(.text+0x44): undefined reference to `boost::system::get_generic_category()' ChecksumTest.cpp:(.text+0x50): undefined reference to `boost::system::get_system_category()' ChecksumTest.cpp:(.text+0x5c): undefined reference to `boost::system::get_system_category()' ChecksumTest.cpp:(.text+0x110): undefined reference to `boost::system::get_system_category()' ChecksumTest.cpp:(.text+0x19c): undefined reference to `boost::system::get_system_category()' ./src/ChecksumTest.o: In function `checkCrc(Tools::Checksum::Type const&amp;, unsigned int const&amp;)': ChecksumTest.cpp:(.text+0x460): undefined reference to `boost::system::get_system_category()' ./src/ChecksumTest.o:ChecksumTest.cpp:(.text+0x6fc): more undefined references to `boost::system::get_system_category()' follow collect2: ld returned 1 exit status make: *** [ChecksumTest_arm-omap3503] Error 1 </code></pre> <p>Same project (even without crosscompiled boost) does link on windows host. So there is something wrong with the generated lib. I spent multiple hours to find my fault without success.</p> <p>Any hints ?!</p> <p>Edit: I now tried to build only the sytem lib by calling: ~/boost/boost_1_49_0$ ./tools/build/v2/b2 toolset=gcc-arm variant=release link=static runtime-link=static stage --with-system</p> <p>Resulting in: ...updated 8 targets...</p> <p>without any further build error. But linking fails also.</p>
