我最近尝试为我的扶手板编译crosstool-ng。 主机是Arch linux 3.9.4-1。 我遇到了以下几个问题：
[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
[ERROR] configure: error: failure running python-config --includes

当我跑步时：
python-config --include
它运作正常，所以我想知道问题出在哪里。 谢谢你的帮助。
答案 0 :(得分：3)
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（我在家中创建一个名为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
