升压BCP不输出任何文件？ [英] Boost BCP doesn't output any files?

问题描述

我试图使用升压复制（BCP）工具拉 normal_distribution 类出加速的。然而，当我做 BCP normal_distribution ./my_normal_distribution_dir ，未出现任何my_normal_distribution_dir目录。

I'm trying to use the Boost Copy (BCP) utility to pull the normal_distribution class out of Boost. However, when I do bcp normal_distribution ./my_normal_distribution_dir, nothing appears in the my_normal_distribution_dir directory.

下面是关于说我在做这个环境的一些更详细的背景：

Here's some more detailed background on the environment that I'm doing this in:

在Mac OS 10.7，我下载了升压1.50和untared源文件。在顶层升压目录中，我做了 ./ bootstrap.sh 。于是，我做了 ./的bjam ./tool​​s/bcp ，它产于./dist/bin目录BCP可执行文件。我创建了一个名为my_normal_distribution_dir目录。然后，我尝试下面的命令来提取 normal_distribution 类：

On Mac OS 10.7, I downloaded the Boost 1.50 and untared source files. In the top-level Boost directory, I did ./bootstrap.sh. Then, I did ./bjam ./tools/bcp, which produced a bcp executable in the ./dist/bin directory. I created a directory called my_normal_distribution_dir. Then, I tried the following commands to extract the normal_distribution class:

./dist/bin/bcp normal_distribution ./my_normal_distribution_dir
./dist/bin/bcp --list normal_distribution --boost=./ ./my_normal_distribution_dir 
./dist/bin/bcp --list normal_distribution --boost=./ output-path:./my_normal_distribution_dir

我使用my_normal_distribution_dir的绝对路径也试过。

I also tried using the absolute path of my_normal_distribution_dir.

所有这些给下面的输出：

All of these give the following output:

no errors detected

不过，尝试所有这些东西之后，my_normal_distribution_dir目录仍然是空的！我该怎么办？

However, after trying all this stuff, the my_normal_distribution_dir directory is still empty! What should I do?

此外，由于<一个href=\"http://stackoverflow.com/questions/11596959/compiling-with-individual-boost-libraries-without-installing-boost\">this螺纹以暗示BCP。一旦我们解决上述问题，应BCP完美处理我的用例。

Also, thanks to this thread for suggesting BCP. Once we solve the problem described above, BCP should handle my use case perfectly.

推荐答案

我想你需要像

bcp --list math/distributions/normal.hpp
