AX_CXX_COMPILE_STDCXX_11 不起作用:意外标记“，"附近的语法错误 [英] AX_CXX_COMPILE_STDCXX_11 doesn't work: syntax error near unexpected token `,'

问题描述

尝试在我的 configure.ac 文件中使用 AX_CXX_COMPILE_STDCXX_11，如下所示:

Trying to use AX_CXX_COMPILE_STDCXX_11 in my configure.ac file like this:

...
AX_CXX_COMPILE_STDCXX_11(, optional)
...

然而，导致错误:

./configure: line 16126: syntax error near unexpected token `,'
./configure: line 16126: `AX_CXX_COMPILE_STDCXX_11(, optional)'

我还放置了 这个文件到configure.ac文件旁边的m4目录中，并且在configure.ac的一开始就调用了AC_CONFIG_MACRO_DIR([m4]).以前有人遇到过这样的事情吗?

I've also placed this file into m4 directory next to configure.ac file and have AC_CONFIG_MACRO_DIR([m4]) called in configure.ac in the very beginning. Did anyone faced anything like that before?

推荐答案

通过运行 autoreconf -f instread of autoconf 解决了我的问题.

My problem solved with running autoreconf -f instread of autoconf.
