从源代码构建python时如何忽略本地python [英] How to ignore local python when building python from source

问题描述

当我尝试使用以下命令构建自己的Python版本：

When I try to build my own version of Python using:

./configure --enable-shared --prefix=/app/vendor/python-dev && make && make install

我在安装过程中看到一些错误：

I see some errors during installation:

/ usr / bin / ld：/usr/local/lib/libpython2.7.a(abstract.o）：针对$ .rodata.str1.8重新定位
R_X86_64_32制作
共享对象时不能使用；用-fPIC重新编译/usr/local/lib/libpython2.7.a：
无法读取符号：错误值

/usr/bin/ld: /usr/local/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32 against `.rodata.str1.8' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libpython2.7.a: could not read symbols: Bad value

当链接器尝试使用 /usr/local/lib/libpython2.7.a 而不是新编译的库时，问题开始。

The problem starts when the linker tries to use /usr/local/lib/libpython2.7.a and not the newly compiled library.

如何防止链接器（配置/制作）使用系统上安装的python库？

How can I prevent the linker (configure/make) from using the python libraries installed on the system?

推荐答案

这似乎是 setup.py 脚本的错误特征，该脚本始终包含 / usr / local make 构建目标 sharedmods 时，在搜索路径中找到code>。

This looks to be a misfeature of the setup.py script always including /usr/local in the search path when make builds the target sharedmods.

您必须手动获取 setup.py ，所以...

You'll have to manually frob the setup.py, so do the...

./configure --enable-shared --prefix=/app/vendor/python-dev

...首先，然后编辑 setup.py ，找到第442、443和444行，如下所示。

...first, then edit setup.py, find lines 442, 443, and 444 which should look like this...

if not cross_compiling:
    add_dir_to_list(self.compiler.library_dirs, '/usr/local/lib')
    add_dir_to_list(self.compiler.include_dirs, '/usr/local/include')

...并注释掉它们，使它们看起来像这样...

...and comment them out so they look like this...

# if not cross_compiling
    # add_dir_to_list(self.compiler.library_dirs, '/usr/local/lib')
    # add_dir_to_list(self.compiler.include_dirs, '/usr/local/include')

...然后 make 应该可以工作。

...then the make should work.
