fcgio.cpp:50: error: 'EOF' was not declare

Question

I am attempting to build fastcgi on a Linux Ubuntu 10.x machine.

I run the following commands:

./configure make

and I get the following error:

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::sync()':
fcgio.cpp:86: error: 'EOF' was not declared in this scope
fcgio.cpp:87: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::underflow()':
fcgio.cpp:107: error: 'EOF' was not declared in this scope
make[2]: *** [fcgio.lo] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/somepath/fcgi-2.4.0'
make: *** [all] Error 2

I notice that others have had the same problem and have asked this question in various fora etc - however, I have not as yet, seen an answer to this question/problem.

Has anyone ever managed to build fastcgi on Linux? How do I fix this problem?

Answer 1

Use -1 instead

EOF is defined in <stdio.h> as follows:

#define EOF (-1)

or (more professionally), you may put the following code above your main() or inside your header file:

#ifndef EOF
#define EOF (-1)
#endif

Answer 2

EOF is a C macro and seems that you do not have it defined in fcgio.cpp or that something has undefined it. I would first try to add #include <stdio.h> to start of fcgio.cpp.

Answer 3

I had the same problem on Ubuntu 11.10 Linux 64bit. Following most of @paercebal's advice I created the following patch which resolved the problem:
