Building boost::log's snprintf.hpp in Sun Studio 12.3: some functions aren't defined that are expected

[Brian Vandenberg <phantall+boost@…>]

I get the following error building with Sun Studio 12.3:

"./boost/log/detail/snprintf.hpp", line 40: snprintf is not defined.
"./boost/log/detail/snprintf.hpp", line 41: vsnprintf is not defined.
"./boost/log/detail/snprintf.hpp", line 44: swprintf is not defined.
"./boost/log/detail/snprintf.hpp", line 45: vswprintf is not defined.

Changes needed are something along the lines of:

#if defined( __SUNPRO_CC )
#include <stdio.h>
#else
#include <cstdio>
#endif

... and

#if defined( __SUNPRO_CC )
using std::swprintf;
using std::vswprintf;
#else
using ::swprintf;
using ::vswprintf;
#endif

The compiler has non-compliant standard headers. This issue can be worked around by Boost.Compatibility.

Should be fixed in [85810].

[Brian Vandenberg <phantall+boost@…>]

I just tried the suggested fix and I'm still seeing errors indicating that snprintf / vsnprintf are not defined.

[Brian Vandenberg <phantall+boost@…>]

ack. my apologies, I'm experimenting with getting boost::asio to build and have -D_XOPEN_SOURCE=1 in my command-line args ... there's some odd stuff going on with that.

[Andrey Semashev]

So, is the problem fixed eventually?

[Brian Vandenberg <phantall+boost@…>]

I should've made that more clear. Yes, I applied the changes you made and the problem gets resolved.
