Linux CrossToolNG python错误

我最近试图为我的arm板编译crosstool ng。 主机是Arch linux 3.9.4-1。 我遇到了以下问题：

[ALL  ]    checking for python... /usr/bin/python
[ALL  ]      File "/home/godard_b/workspace/raspberry_pi/staging/.build/src/gdb-7.4.1/gdb/python/python-config.py", line 47

当我跑步时：

python-config --include

它工作正常，所以我想知道问题出在哪里。

谢谢你的帮助。

我也遇到了同样的问题，问题在这里：

[ALL  ]        print to_unix_path(sysconfig.PREFIX)
[ALL  ]                         ^
[ALL  ]    SyntaxError: invalid syntax

这意味着它使用的是python3而不是Python2，可能是因为Python指向python3（这是Arch中的默认值）k

要解决此问题，只需创建一个新目录（我在home上创建了一个名为bin的目录），并创建两个名为python和python config的符号链接，指向python2和python2 config：

mkdir ~/bin
ln -s /bin/python2 ~/bin/python
ln -s /bin/python2-config ~/bin/python-config

现在，再次尝试构建crosstool ng，在路径的开头添加带有python链接的dir：

PATH=$HOME/bin:$PATH crosstool-ng build
