尝试在我的代码中静态链接 boost 程序选项库时，我在链接器尝试链接它时遇到错误。

我不希望在我的测试程序中使用动态绑定，因此如果我在进行链接时缺少要包含的任何库，则需要任何指针。

问题是我链接到我的程序的方式。我正在做如下

g++ -g test.cxx -o test -L/<path>/boost_1_39_0/lib/Linux64//libboost_program_options-gcc41-mt-1_39.a

而我们需要做如下

g++ -g test.cxx -o test /<path>/boost_1_39_0/lib/Linux64//libboost_program_options-gcc41-mt-1_39.a

这将解决问题。

您正在使用编译器开关-L错误。在 gcc -L中用于指定要搜索库的目录。但是，这意味着如果您没有在附加标志-l之后指定库名称，它将无法链接该库以形成您想要的可执行文件。

因此，在这种情况下，您将执行以下操作：

g++ -g test.cxx -o test -L/<path>/boost_1_39_0/lib/Linux64/ -lboost_program_options-gcc41-mt-1_39
