有关CUDA-cum-Boost交互的问题偶尔会出现在SO上，但它们总是（？）关于编译：CUDA在使用Boost的巫术技巧方面遇到了麻烦。常识是使用Boost从CUDA编译的代码中隔离代码。
所以，我已经做到了这一点：我正在编写一个小型CUDA实用程序，其中boost::program_options很有限地用于实现单个类。我的问题在于链接。
我正在使用Debian Stretch（64位），它是用GCC 5.x构建的（这包括它的Boost 1.58软件包）。然而，我在本地安装的CUDA 7.5只能使用gcc 4.9.x或更早版本，这就是我使用的。编译完所有内容后，仍会保留未定义的引用。也就是说，在我这样做之后：
/usr/bin/g++-4.9 -Wall -std=c++11 originally_cu.o originaly_cpp.o weird_cmake_generated_intermediate_link.o -o foo_app -rdynamic /usr/local/cuda/lib64/libcudart_static.a -lpthread -lrt -ldl -lboost_log -lboost_system -lboost_program_options /usr/local/cuda/lib64/libcudart_static.a -lpthread -lrt -ldl -lboost_log -lboost_system -lboost_program_options
（CMake产生了这一点，我不确定为什么我会看到双-l s）
我明白了：
originally_cpp.o: In function `FooConfiguration::getFromProgramArguments(int, char**)':
FooConfiguration.cpp:(.text+0x5d4): undefined reference to `boost::program_options::options_description::options_description(std::string const&, unsigned int, unsigned int)'
FooConfiguration.cpp:(.text+0x6ca): undefined reference to `boost::program_options::options_description::options_description(std::string const&, unsigned int, unsigned int)'
FooConfiguration.cpp.o: In function `boost::program_options::validation_error::validation_error(boost::program_options::validation_error::kind_t, std::string const&, std::string const&, int)':
FooConfiguration.cpp:(.text._ZN5boost15program_options16validation_errorC2ENS1_6kind_tERKSsS4_i[_ZN5boost15program_options16validation_errorC5ENS1_6kind_tERKSsS4_i]+0x2e): undefined reference to `boost::program_options::validation_error::get_template(boost::program_options::validation_error::kind_t)'
等等。
我想也许这与Boost是用gcc 5.x构建的事实有关;所以，我下载了Boost 1.60，用gcc 4.9构建它，并将其安装在/opt/boost下（编辑：并将/opt/boost/lib添加到`LD_LIBRARY_PATH）。但是当我尝试使用它时，它很好 - 它构建了，但我在Boost中得到了分段违规（而且我知道我不应该，因为相同的代码在另一台机器上运行，至少到了解析命令行的程度）参数）。这是来自gdb的回溯：
