我正在尝试使用 gcc 8.3.0 在 cygwin 上编译和构建 libsigc++-2.10.2。
$ gcc --version
gcc (GCC) 8.3.0

当我运行 ./configure 时，我得到：
checking whether make supports the include directive... yes (GNU style)
checking dependency style of g++... gcc3
checking whether g++ supports C++11 features by default... no
checking whether g++ supports C++11 features with -std=c++11... no
checking whether g++ supports C++11 features with +std=c++11... no
checking whether g++ supports C++11 features with -h std=c++11... no
checking whether g++ supports C++11 features with -std=c++0x... no
checking whether g++ supports C++11 features with +std=c++0x... no
checking whether g++ supports C++11 features with -h std=c++0x... no
configure: error: *** A compiler with support for C++11 language features is required.
如果我尝试运行 autogen.sh 那么它会抛出：
configure.ac:28: installing 'build/missing'
Makefile.am:20: error: ENABLE_DOCUMENTATION does not appear in AM_CONDITIONAL
build/doc-reference.am:64: error: DIST_DOCTOOLS does not appear in AM_CONDITIONAL

请指教，谢谢！！
