Question

我尝试使用curses支持编译和安装Python失败了，我在编译标志上尝试了各种迭代等等，似乎无法使这个东西工作。

这是在Solaris 11上，Python版本3.4.3：

首先，这是问题：

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'

各种Googlez告诉我，这是因为在编译Python时，找不到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，传递了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

这似乎应该这样做。 config.log似乎没有表明任何失败。

checking curses.h usability... yes
checking curses.h presence... yes
checking for curses.h... yes
checking ncurses.h usability... yes
checking ncurses.h presence... yes
checking for ncurses.h... yes

我还尝试使用Solaris打包工具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

然后我尝试了：

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

在任何一种情况下，情况相同：

ImportError: No module named '_curses'

编辑更新：

我刚刚意识到curses模块是在“make install”期间构建的，而不是“make”，所以我错过了一些关键错误。特别是在使用ncurses的/ usr / local / pkg安装时：

当我最初发布时，我没有使用“--with-shared”编译ncurses。我用那个选项重新编译了ncurses，之后，这个工作：

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

看来你热衷于重新发明轮子。我建议你看一下NetBSD的PKGSRC，它与Solaris兼容，现在效果很好......甚至还有SUN Studio编译器。 SmartOS / Illumos的二进制包可以在Solaris 11上开箱即用（如果你是x86）。

请注意，在autotools配置+向PATH注入假gcc，ld，as命令后，这些打包内容确实有一些补丁+修补补丁文件，这些命令改变了cmdline参数真正的编译器。你真的想重新发明这一切吗？
