我最近尝试为我的手臂板编译 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
[ALL  ]        print to_unix_path(sysconfig.PREFIX)
[ALL  ]                         ^
[ALL  ]    SyntaxError: invalid syntax

当我运行时：

python-config --include

它工作正常，所以我想知道问题可能出在哪里。谢谢你的帮助。

我有同样的问题，问题出在这里：

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

这意味着它使用的是 Python 3 而不是 Python 2，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 PATH 开头的 python2 处添加带有 python 链接的目录：

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