使用ax_check_compile_flag的autotools语法错误
[英]autotools syntax error with ax_check_compile_flag
问题描述
I am using autotools for building my C++ application. 
我正在使用autotools来构建我的C ++应用程序。 In my configure.ac I have the following line: 在我的configure.ac中，我有以下行：
AX_CHECK_COMPILE_FLAG([-Wall], [CPPFLAGS="$CPPFLAGS -Wall"])
which causes the following error when executing ./configure (after running autoreconf -i ): 执行./configure （运行autoreconf -i之后 ）会导致以下错误：
./configure: line 3825: syntax error near unexpected token `-Wall,'
./configure: line 3825: `AX_CHECK_COMPILE_FLAG(-Wall, CPPFLAGS="$CPPFLAGS -Wall")'
My system: Linux web 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux 我的系统： Linux web 3.2.0-4-amd64＃1 SMP Debian 3.2.65-1 + deb7u2 x86_64 GNU / Linux
On my Ubuntu machine it works well, why do I get this error? 在我的Ubuntu机器上运行良好，为什么我会收到此错误？

autoreconf isn't magic (though I encounter package maintainers who obviously believe this). autoreconf并不神奇（虽然我遇到明显相信这个的软件包维护者）。 When you ran autoreconf , it failed to find the AX_CHECK_COMPILE_FLAG macro, and produced a corrupt configure script. 运行autoreconf ，无法找到AX_CHECK_COMPILE_FLAG宏，并生成了损坏的configure脚本。 Usually that produces an error/diagnostic message at the same time. 通常，它会同时产生错误/诊断消息。
'AX_CHECK_COMPILE_FLAG` comes from the autoconf archive project, and Debian has a package which provides this, named autoconf-archive . 'AX_CHECK_COMPILE_FLAG`来自autoconf归档项目，Debian有一个提供此命名的包，名为autoconf-archive 。 Likely, you forgot to install it: 可能，你忘了安装它：
sudo apt-get install autoconf-archive
