pip error: unrecognized command line option ‘-fstack-protector-strong’
提问by cooltoast
When I sudo pip install pyquery, sudo pip install lxml, and sudo pip install cython, I get very similar output with the same error that says:
当 I sudo pip install pyquery、sudo pip install lxml、 和 时sudo pip install cython，我得到非常相似的输出，并显示相同的错误：
x86_64-linux-gnu-gcc: error: unrecognized command line option ‘-fstack-protector-strong'

I ran into this problem when I attempted to upgrade my pandas version to 0.15.2
当我尝试将我的 Pandas 版本升级到 0.15.2 时遇到了这个问题
If you install gcc-4.9 you are likely to still have an older version of gcc on your system (gcc-4.7 in my case).
如果您安装 gcc-4.9，您的系统上可能仍然有旧版本的 gcc（在我的例子中是 gcc-4.7）。
I can think of 3 ways to solve this issue:
我可以想到3种方法来解决这个问题：
a) symlink /usr/bin/x86_64-linux-gnu-gcc to /usr/bin/x86_64-linux-gnu-gcc-4.9 if you want to be more organized about this use update-alternatives, see https://askubuntu.com/questions/26498/choose-gcc-and-g-version
a) 将 /usr/bin/x86_64-linux-gnu-gcc 符号链接到 /usr/bin/x86_64-linux-gnu-gcc-4.9 如果您想对此使用更有条理，请使用update-alternatives，请参阅https://askubuntu .com/questions/26498/choose-gcc-and-g-version
b) figure out how to manually specify which compiler pip uses and set it in some sort of .conf file - I haven't examined where this file lives or if there are CLI options for pip that accomplish the equivalent. In principle, creating/editing a /usr/lib/pythonX.Y/distutils/distutils.cfg should do it. I ran into problems when I tried to use this approach.
b) 弄清楚如何手动指定 pip 使用的编译器并将其设置在某种 .conf 文件中 - 我还没有检查过这个文件所在的位置，或者是否有 pip 的 CLI 选项可以完成等效操作。原则上，创建/编辑 /usr/lib/pythonX.Y/distutils/distutils.cfg 应该这样做。当我尝试使用这种方法时遇到了问题。
c) Edit /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py to reflect your updated compiler
c) 编辑 /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py 以反映您更新的编译器

回答by Sjoerd
One possible solution would be to use GCC 4.9 or higher, which does support the -fstack-protector-strongflag.
一种可能的解决方案是使用支持该-fstack-protector-strong标志的GCC 4.9 或更高版本。
回答by user323094
Instead of upgrading to GCC 4.9, I was trying to find where the flag was defined and remove it. On Debian Wheezy, I found it in /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py which belongs to the libpython2.7-minimal package. My solution was to replace all occurrences of -fstack-protector-strong with -fstack-protector within this file. Then pip install executed the correct build command.
我没有升级到 GCC 4.9，而是试图找到定义标志的位置并将其删除。在 Debian Wheezy 上，我在 /usr/lib/python2.7/plat-x86_64-linux-gnu/_sysconfigdata_nd.py 中找到了它，它属于 libpython2.7-minimal 包。我的解决方案是在这个文件中用 -fstack-protector 替换所有出现的 -fstack-protector-strong 。然后 pip install 执行了正确的构建命令。
