c++ - boost 程序选项 : linking error

Question

我在服务器上编译我的 C++ 代码时遇到错误。

所以在这个特定的服务器上，安装的标准 g++ 是版本 4.4.6，我不能将其用于我的程序，因为我需要 -std=c++14。

所以我使用了一个不同的版本，它安装在另一个用户的主目录中，这是一个版本 7.1，用命令 g++_71 调用。

除了我使用 boost program_options 的一个类之外，了解所有文件的编译情况。

当只链接到 -lboost_program_options 时，它不会工作，因为它会链接到旧版本的 boost，它不支持我正在使用的功能，并且也是用 4.4.6 gcc 编译的。

因此我下载了 boost 版本 1.66.0 并将其安装在我的主目录中我命名为 boost 的文件夹中。我确保使用正确的工具集 g++_71 安装了 boost，即使这不应该改变 program_options 所在的仅 header 库的内容。

现在我仍然遇到链接器错误:

make: *** [ACOPPD] Error 1

我尝试了不同的技术来解决这个错误:

• 我尝试只执行推荐的 include :#include "boost/program_options.hpp" 和 -I/home/mkupper/boost/boost_1_66_0仅 header 库的 boost 文档推荐的 Makefile，即 program_options。

• 我试图包含完整路径:#include "/home/mkupper/boost/boost_1_66_0/boost/program_options.hpp"

• 我尝试将 -I/home/mkupper/boost/boost_1_66_0 -L/home/mkupper/boost/boost_1_66_0/libs 包含到链接器和编译器标志中。

• 除了其他包含之外，我还尝试包含 -lboost_program_options。

• 我试过 -lstdc++ 是否会改变任何东西。

没有什么改变链接器错误，我很无奈!

这是我当前的 Makefile:

CFLAGS  := -std=c++14 -Wall -Ofast -march=native -Wunused-parameter
LDFLAGS :=  -lstdc++ -I /home/mkupper/boost/boost_1_66_0 -L /home/mkupper/boost/boost_1_66_0/libs

OBJEXT := o

OBJECTS := $(addprefix $(BUILDDIR)/,$(SOURCES:%.$(SRCEXT)=%.$(OBJEXT)))

Answer 1

-I选项表示编译器需要在哪里找到包含文件，因此它属于编译器标志CFLAGS。

-L 选项指示链接器需要在哪里找到库文件，-l 选项告诉链接器要包含哪些库，因此两者都应该进入LDFLAGS。

说到这里，您错过了 LDFLAGS 中的 -lboost_program_options 标志。因此，链接器不会包含 boost_program_options 库。 -L 单独在这里是没有意义的。

底线 - 试试这些:

CFLAGS  := -std=c++14 -Wall -Ofast -march=native -Wunused-parameter -I/home/mkupper/boost/boost_1_66_0
LDFLAGS :=  -L/home/mkupper/boost/boost_1_66_0/libs -lstdc++ -lboost_program_options
