在运行 ubuntu 的服务器中构建 FastCGI 时出错

我想在运行 ubuntu 的服务器中将 FCGI 与我的C++代码连接起来。我没有在 FCGI 网站的测试平台列表下找到 ubuntu，但我还是尝试构建它。

./configure似乎工作正常。但是，当我运行make时，我收到 2 个错误，如下所示：

fcgio.cpp: In destructor 'virtual fcgi_streambuf::~fcgi_streambuf()':
fcgio.cpp:50: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::overflow(int)':
fcgio.cpp:70: error: 'EOF' was not declared in this scope
fcgio.cpp:75: error: 'EOF' was not declared in this scope

fcgio.cpp: In member function 'virtual int fcgi_streambuf::underflow()':

make[1]: Leaving directory '/home/giridhar/fcgi-2.4.1-SNAP-0910052249'

解决此问题将不胜感激。
