#6988 new defect

AMIGAOS4: --enable-c++11 breaks compilation of commandline.cpp

Reported by: raziel- Owned by:
Priority: normal Component: Port: AmigaOS4
Keywords: Cc:


Using the flag --enable-c++11 with configure makes the compiler break with an error early on 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 -std=c++11 on a test program.



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
