没有找到编译选项可以调整需要支持的语言。
比如，我只需要中英文就好了，编译其它的又看不懂，既浪费硬盘，又浪费时间。

---------------------------------
移除不需要的语言对应的文件夹自然是可以的，但是没有更好的办法吗？

嗯,应该似乎是没有..所以我一直以为编译没太多选项

俺只编译过 wesnoth pidgin 和 wine

我在官网论坛问了。

解决方法如下：
The cleanest solution I've found is modifying m4/po.m4 which appears to handle which translations are compiled and installed. You can specify which translations you would like to build by modifying the ALL_LINGUAS_ variable (around line 125).

For example, I would change:
ALL_LINGUAS_=`sed -e "/^#/d" -e "s/#.*//" "$ac_given_srcdir/$ac_dir/LINGUAS"`
to
ALL_LINGUAS_="en_GB"
to enable only British English. Additional translations should be separated by a space.

After modifying, run ./autogen.sh and use your usual build sequence.

Hope that helps.

用./configure --help查一下，该有就有，没就没。写程序的人大概不会BT到没写参数帮助吧
