尝试在Python3.4上构建lxml：系统具有libxml2和libxslt。配置返回的代码256 - python setup.py egg_info失败，错误代码1在/ tmp/pip_build_root/lxml中
PIP构建不能确定多核，除其他事项外
相关版本下载（？）（？）：
- LXML-3.4.1
- libiconv的1.14
- libxml2-2.9 0.2
- 的libxslt-1.1.28
首先，尝试标准版本（动态）：
$ CFLAGS="-O0" pip3 install lxml
建立没有错误，但：
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
符号出现，但是：
$ nm /usr/lib/python3.4/site-packages/lxml/etree.cpython-34m.so | grep __xmlStructuredErrorContext
U __xmlStructuredErrorContext
不过是 '本地'在底层libxml2中：
# nm /usr/lib/libxml2.so.2 | grep __xmlStructuredErrorContext
000d69d0 t __xmlStructuredErrorContext
OK，尝试建立STATIC，如建议：
$ STATIC_DEPS=true CFLAGS="-O0" pip3 install lxml
...

对于第一种情况，'etree * so'库指向哪个库（'ldd ...'）？我的猜测是'xmlStructuredErrorContext'缺少一个，可能是因为其中一个链接库已经被弃用，或者因为它太旧而错过了。 – Evert
为动态构建，例如，它找到libxml2的系统库 - v2.9.2。 另一张海报表明这个符号上的'本地'标志可能是问题所在？合理？ ＃nm /usr/lib/libxml2.so.2 | grep __xmlStructuredErrorContext 000d69d0 t __xmlStructuredErrorContext – DrLou
尝试使用像[this]这样的python发行版（http://continuum.io/downloads）。特别帮助我解决lxml问题，以及许多其他问题。 – bahmait
