COMPILER: --enable-c++11 breaks compilation in commandline.cpp (AmigaOS4)

Description (last modified by raziel-)

Using the flag


with configure, makes the compiler error early in commandline.cpp.

    C++      base/commandLine.o
	base/commandLine.cpp: In function 'void Base::usage(const char*, ...)':
base/commandLine.cpp:162:36: error: 'vsnprintf' was not declared in this scope
      vsnprintf(buf, STRINGBUFLEN, s, va);
	gmake: *** [base/commandLine.o] Error 1

The same (or at least something similar) happens when using the flag


on a test program.

#include <stdio.h>
#include <stdarg.h>
void test() { va_list ap; vsnprintf(0, 0, 0, ap); }

Building it with

g++ -c -o test.o test.cpp

works fine, but adding the c++11 flag and using

g++ -c -o test.o test.cpp -std=c++11

throws this error

test.cpp: In function 'void test()':
test.cpp:5:48: error: 'vsnprintf' was not declared in this scope
 void test() { va_list ap; vsnprintf(0, 0, 0, ap); }

Looks like a broken toolchain. vsnprintf is part of C++11 (see:

You might need to update your C library's development headers.

Not broken, it seems it's not yet supported:

Probably can be closed then

In the upgraded Buildbot, I plan on enabling all platforms to build with C++11 by default soon, so whatever needs to be fixed for this to be fixed will be addressed at that point.

I don't really think that there si anything that needs "fixing", more a case of "supporting".

It seems the c++11 is simply not yet implemented in out adtools.

But anyway, thanks alot for taking a look
