我在编译Emacs 23.3 Release Candidate 2时遇到问题：
我运行autogen.sh，./configure，make，最后make install，我收到此错误：

我之前从未见过这样的错误。这是什么意思？
答案 0 :(得分：17)
我在旧的Linux版本（RHEL 4.9）上遇到过类似的问题。
按照Eric Johnson的链接，这样的配置对我有用：
./configure CPPFLAGS="-fgnu89-inline"
答案 1 :(得分：5)
我正在尝试构建和安装GNU emacs-24.3：
> uname -a
Linux mymachine 2.6.18-274.12.1.el5 #1 SMP Tue Nov 8 21:37:35 EST 2011 x86_64 x86_64 x86_64 GNU/Linux
> pwd
emacs-24.3
> ./configure
> make
并且几乎完全相同＆＃34;多重定义＆＃34;用户815423426报告的错误。
在充分理解＆＃34; -fgnu89-inline＆＃34;之前意思是，我只是使用了Nemo的魔法线，瞧，它经历了：
> ./configure CPPFLAGS="-fgnu89-inline"
> make
> make install
