生成NumPy时出错：找不到lpython2.7

Question

我需要在这里的集群上构建NumPy（我没有根访问权限）。我已经编译了我自己的Python2.7.3版本（使用--enable shared），而且由于我没有根访问权限，所以Python位于非标准位置。不过，我在编译NumPy时遇到了一个问题。我得到的是：

gfairchild@cj-fe1 ~/code/packages/src/numpy-1.6.2> export CFLAGS="-L/usr/projects/infmodels/gfairchild/packages/lib"
gfairchild@cj-fe1 ~/code/packages/src/numpy-1.6.2> python setup.py build --fcompiler=gnu95

由于某些原因，即使它在CFLAGS指定的目录中，也找不到{}。我甚至把目录添加到LD_LIBRARY_PATH：

^{pr2}$

我该怎么做才能让这个工作起来？谢谢！在

Answer 1

我认为您需要将-L/some/path选项放入LDFLAGS，而不是CFLAGS。CFLAGS[通常]传递给编译器，LDFLAGS[通常]传递给链接器，而您看到的是链接器错误：）

顺便说一下，在这种情况下，错误出现在Fortran编译器错误之后。您也可以尝试在FCFLAGS中提供-L（即使它不是真正的编译器，而是链接器标志。。这只是为了以防万一你真的非常渴望黑客攻击）。在

Answer 2

我刚修好了！在numpy-1.6.2目录中，我看到一个名为site.cfg.example的文件。从里面看，我看到您可以指定库和包含目录。我只创建了一个名为site.cfg的文件，其内容如下：

[DEFAULT]
library_dirs = /usr/projects/infmodels/gfairchild/packages/lib:/usr/local/lib
include_dirs = /usr/projects/infmodels/gfairchild/packages/include:/usr/local/include

这就是它完成建造所需的全部。m01的解决方案（添加LDFLAGS的路径）让我走得更远，但仍然出错了。site.cfg文件允许它完成生成。在
