我尝试编译和安装支持curses的Python，但是一直失败了。我已经尝试了各种编译标志等迭代操作，但似乎无法使其正常工作。
这是在Solaris 11上，Python版本为3.4.3：
首先，这里是问题所在：
Python 3.4.3 (default, Mar 3 2015, 14:43:41)
[GCC 4.5.2] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import curses
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/pkg/python/3.4.3/lib/python3.4/curses/__init__.py", line 13, in <module>
from _curses import *
ImportError: No module named '_curses'
一些谷歌用户告诉我，造成这个问题的原因是Python编译时未找到ncurses库。
所以我从ftp://ftp.gnu.org/gnu/ncurses/(5.9)安装了curses到/usr/local/pkg/ncurses/5.9，并尝试重新编译Python，并传入ncurses的位置:
export LDFLAGS=-L/usr/local/pkg/ncurses/5.9/lib
export CPPFLAGS="-I/usr/local/pkg/ncurses/5.9/include -I/usr/local/pkg/ncurses/5.9/include/ncurses"
./configure --enable-shared --prefix=/usr/local/pkg/python/3.4.3
make
make install
看起来应该可以了。config.log 没有显示任何失败。

我也尝试使用Solaris packaging工具OpenCSW来安装这些软件包：
libncurses5 CSWlibncurses5 5.9,REV=2011.11.21 298.2 KB
libncurses_dev CSWlibncurses-dev 5.9,REV=2011.11.21 258.4 KB
libncursesw5 CSWlibncursesw5 5.9,REV=2011.11.21 341.5 KB
mutt_ncurses CSWmutt-ncurses 1.5.23,REV=2014.03.14 484.4 KB
ncurses CSWncurses 5.9,REV=2011.11.21 123.1 KB
接下来我尝试了：
export LDFLAGS=-L/opt/csw/lib
export CPPFLAGS="-I/opt/csw/include -I/opt/csw/include/ncursesw"
./configure --enable-shared --prefix=/usr/local/pkg/python/3.4.3
make
make install
无论哪种情况，情况都是一样的：
ImportError: No module named '_curses'
编辑更新:
我刚意识到 curses 模块是在 "make install" 期间构建的，而不是在 "make" 期间，因此我错过了一些关键错误。特别是在使用 /usr/local/pkg 安装的 ncurses 时:

cd /usr/lib; ls -l libncurses*的输出是什么？ - l'L'l-I/usr/local添加到CPPFLAGS，并将-L/usr/lib添加到LDFLAGS；看起来你已经合理地设置好了一切。 - l'L'l
