linux - Crosstool-ng python 错误

Question

我最近尝试为我的 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
[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，所以我想知道问题出在哪里。感谢您的帮助。

我遇到了同样的问题，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 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

要解决这个问题，只需创建一个新目录(我在家里创建了一个名为 bin 的目录)并创建两个名为 python 和 python-config 的符号链接(symbolic link)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 的开头添加带有 python 链接的目录:

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