Question

尝试在Python3.4上构建lxml：系统确实有libxml2和libxslt。

pp build无法确定MULTICORE（？）等（？）

下载了相关版本：

LXML-3.4.1
libiconv的-1.14
libxml2-2.9.2
的libxslt-1.1.28

首先，尝试标准构建（动态）：

$ CFLAGS="-O0" pip3 install lxml

构建没有错误，但是：

Python 3.4.2 (default, Dec 13 2014, 16:48:48) 
[GCC 4.8.3] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> from lxml import etree
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: ld.so.1: isapython3.4: fatal: relocation error: file /usr/lib/python3.4/site-packages/lxml/etree.cpython-34m.so: symbol __xmlStructuredErrorContext: referenced symbol not found

符号存在，但是：

$ nm /usr/lib/python3.4/site-packages/lxml/etree.cpython-34m.so | grep __xmlStructuredErrorContext
         U __xmlStructuredErrorContext

但是，本地＆＃39;在底层的libxml2中：

# nm /usr/lib/libxml2.so.2 | grep __xmlStructuredErrorContext
000d69d0 t __xmlStructuredErrorContext

好的，按照建议的那样尝试构建STATIC ：

$ STATIC_DEPS=true CFLAGS="-O0" pip3 install lxml

...

**Exception: Command "make -j6" returned code 256**

Building lxml version 3.4.1.

Latest version of libiconv is 1.14
Latest version of libxml2 is 2.9.2
Latest version of libxslt is 1.1.28

Answer 1

我的注意力被这个错误所吸引：

**Exception: Command "make -j6" returned code 256**

尝试将安装命令更改为：

STATIC_DEPS=true CFLAGS="-O0" pip3 install lxml --install-option="--multicore=1"

这是一个古老的问题，我希望它可以帮到某个人。

配置返回的代码256 - python setup.py egg_info失败，错误代码为1 / tmp / pip_build_root / lxml
