为什么我不能在 /usr/include 中安装 boost？
我正在尝试将 boost 安装到包含目录中，以避免在每个 g++ 编译器调用中使用 -I 标志，我使用以下命令行安装：./bjam - -prefix=/usr/include 安装 查看--prefix值，它安装在/home/myusername中，为什么？ 提前致谢。
I'm trying to install boost into include directory for avoid -I flag use in each g++ compiler call,I installed using this command line: ./bjam --prefix=/usr/include install
see --prefix value, it install in /home/myusername, why?
Thanks in advance.

您需要 root 权限才能安装在
/usr/include中。事实上，你的系统不让你这么做，已经帮了你一个忙了。
--prefix选项表示安装所有内容的位置 - 头文件、库、可执行文件、文档等。例如，头文件将安装在/ usr/include/include，它不会出现在编译器的搜索路径中。免责声明：：假设
./bjam --prefix=...的行为与./configure --prefix=...类似。我实际上并没有使用过bjam。如果bjam的--prefix选项有其他含义，请纠正我。根据您的系统，您也许可以从存储库安装 Boost，而不是从源代码构建它。例如，对于 Debian 或 Ubuntu，诸如
sudo apt-get install libboost之类的东西可能会起作用。请注意，我说过类似的话； Boost 似乎由许多包组成；
apt-cache search boost，或者更好的是，进行 Google 搜索以了解如何在您的特定系统上安装 Boost。You would need root permissions to install in
/usr/include.Actually your system has done you a favor by not letting you do that. The
--prefixoption says where to install everything -- headers, libraries, executables, documentation, etc. For example, the header files would be installed in/usr/include/include, which is not going to be in your compiler's search path.Disclaimer:: This assume that
./bjam --prefix=...behaves similarly to./configure --prefix=.... I haven't actually usedbjam. Ifbjam's--prefixoption means something else, please correct me.Depending on your system, you may be able to install Boost from a repository rather than building it from source. For Debian or Ubuntu, for example, something like
sudo apt-get install libboostmight work.Note that I said something like that; it appears that Boost consists of a number of packages;
apt-cache search boost, or better yet, do a Google search to see how to install Boost on your particular system.尝试运行
这样做应该以适当的权限运行
bjam以安装到/usr/local/include和/usr/local/lib，两者它应该在你的搜索路径中......Try running
Doing this should run
bjamwith appropriate privileges to install to/usr/local/includeand/usr/local/lib, both of which should be in your search path...
