Original GitHub issue: https://github.com/ADD-SP/ngx_waf/issues/50
如果不加参加数--with-cc-opt='-std=gnu99'会报建如下错
For gcc, you can enable the C99 standard by appending the parameter --with-cc-opt='-std=gnu99'.
如果加上参数--with-cc-opt='-std=gnu99'会报如下错误，
cc1plus: error: command line option ‘-std=gnu99’ is valid for C/ObjC but not for C++ [-Werror]
这个需要怎么解决呢
@ADD-SP commented on GitHub (Jul 1, 2021):
看起来编译器把 C 源代码文件识别为 C++ 源代码文件了。使用的编译器是 GCC 么？贴一下完整的
./configure参数看看。@R1hug0 commented on GitHub (Jul 2, 2021):
可能是GCC版本太低了？ 版本是 gcc-4.8.5

@ADD-SP commented on GitHub (Jul 2, 2021):
尝试把三个
--with-cc-opt参数中的值合并到一个--with-cc-opt里，因为只有最后一个--with-cc-opt会生效。如果不行的话尝试编辑
objs/Makefile，从CFLAGS删除-Werror，然后重新编译。@R1hug0 commented on GitHub (Jul 2, 2021):
试了下不行，我升级下GCC到7.0试试
@ADD-SP commented on GitHub (Jul 4, 2021):
@R1hug0 解决了么？
@R1hug0 commented on GitHub (Jul 5, 2021):
升级了GCC8.3，make的时候抛出下面的错误

在
--with-cc-opt中追加-Wno-array-bounds。@R1hug0 commented on GitHub (Jul 5, 2021):
Ok, done
