c++ - 在 Ubuntu 13.04 上链接 boost::filesystem

Question

我正在尝试将一个项目链接到 Ubuntu 13.04 上的 boost:filesystem，但在最后阶段我遇到了一些奇怪的链接错误。

构建配置是通过 cmake 完成的:

find_package(Boost COMPONENTS system filesystem program_options REQUIRED )
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})

target_link_libraries(${YARS_TARGET} yarsLib GLEW GL GLU glut m dl xerces-c ode ${Boost_LIBRARIES})

我尝试使用不同的 boost 版本。对于 1.49 和 1.53，我有相同的行为。在 Ubuntu 12.04 上，它确实可以正常工作，而在我运行 Archlinux 和 boost 1.53 的开发机器上，它编译、链接和运行都很好。

Answer 1

只是一个建议:

1) 检查你的 boost 库是否包含所需的符号，你可以使用这样的东西:nm -D/usr/lib64/libboost_filesystem.so.1.52.0 |详细信息 | C++过滤器 | grep 你的名字

2)尝试更改链接库的顺序，例如将 -lboost_bla-bla-bla 放在命令行的末尾，然后再次使用 g++ 运行此命令，不要使用 make 或其他东西，只需复制粘贴命令并进行实验与它。
