Question

我正在尝试从启用了fpectl模块的Docker容器内的源代码安装Python 2.7.14。

使用official Python jessie Dockerfile作为起点，我已将--with-fpectl配置选项添加到./configure命令。

您可以看到我的docker build命令in this gist的完整输出;然而，这里有一些有趣的内容：

./configure --build=x86_64-linux-gnu --enable-shared --enable-unicode=ucs4 --with-fpectl
...
checking for --with-fpectl... yes
...
x86_64-linux-gnu-gcc -pthread -fPIC -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -IInclude -I./Include -I/usr/include/x86_64-linux-gnu -I/usr/local/include -I/usr/src/python/Include -I/usr/src/python -c /usr/src/python/Modules/mathmodule.c -o build/temp.linux-x86_64-2.7/usr/src/python/Modules/mathmodule.o

 extern double PyFPE_dummy(void *);
               ^
...
Python build finished, but the necessary bits to build these modules were not found:
bsddb185           dl                 imageop         
sunaudiodev                                           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

（我实际上认为来自mathmodule.c的错误消息是良性的，但我认为我会将其包含在上下文中，因为它是唯一似乎与{{1}相关的其他输出}模块。）

当我使用此版本创建的图像启动容器时，我安装了Python，但没有fpectl模块：

fpectl

通过aptly 提供的--with-fpectl包似乎包含python模块（见下文）。但是，在这种情况下，由于各种原因（包括使用最新的2.7.x的能力），我更倾向于从源代码构建。我曾尝试检查用于Python软件包安装的配置选项，但在我自己的Docker构建中使用这些选项似乎也没有安装模块。

通过apt：

安装

fpectl

尽管如此，我缺少什么？是否需要一些额外的系统包来启用此模块，或者在配置步骤中需要一些额外的标志？

如何使用fpectl模块从源安装Python 2.7？
