【问题描述】：

我虔诚地关注http://www.boost.org/doc/libs/1_61_0/more/getting_started/windows.html。

下载并解压 1.61 版本的 boost 后，我尝试按照本指南 5.1 节中的说明从源代码构建它。所以

bootstrap
.\b2

然后我得到错误：

error: Unable to load Jamfile.
error: Could not find a Jamfile in directory 'libs/config/checks/architecture'.
error: Attempted to find it with pattern '[Bb]uild.jam [Jj]amfile.v2 [Jj]amfile [Jj]amfile. [Jj]amfile.jam'.
error: Please consult the documentation at 'http://www.boost.org'.

与Trac issue #12173 of boost 完全相同。出了什么问题？如何让 bjam 找到 jam 文件？

【解决方案1】：

有点过时了，但我可以通过获取config 子模块来完成这项工作：

git submodule update --init libs/config

似乎配置模块是其他一些模块的未列出的先决条件。

【解决方案2】：

当“bootstrap.jam”试图从错误的路径加载构建系统的模块时，可能会发生此错误。

确保BOOST_BUILD_PATH 设置为“boost*/tools/build”并且未设置BOOST_ROOT。

错误配置示例：

libtorrent-rasterbar-1.2.0>set BOOST_BUILD_PATH=..\boost_1_68_0
libtorrent-rasterbar-1.2.0>set BOOST_ROOT=..\boost_1_68_0
libtorrent-rasterbar-1.2.0>b2

FIXED 配置示例：

libtorrent-rasterbar-1.2.0>set BOOST_BUILD_PATH=..\boost_1_68_0\tools\build
libtorrent-rasterbar-1.2.0>set BOOST_ROOT=
libtorrent-rasterbar-1.2.0>b2
