[lexical_cast][random] ADL problem with gcc c++11
Hi, I can't get this to compile on gcc-4.6.1 with -std=c++0x flag: #include <boost/random.hpp> int main() { return 0; } I'm getting an error in lexical_cast: C:\dev\boost/boost/lexical_cast.hpp:1323:120: error: there are no arguments to 'swprintf' that depend on a template parameter, so a declaration of 'swprintf' must be available [-fpermissive] Obviously, I can compile with -fpermissive, but I'd like to report this anyway.

Hi,
I can't get this to compile on gcc-4.6.1 with -std=c++0x flag:
#include <boost/random.hpp>
int main() { return 0; }
I'm getting an error in lexical_cast:
Could not reproduce it with trunk version and gcc-4.6.1-9ubuntu3. Which version of boost are you using? -- Best regards, Antony Polukhin

I tested both trunk and release branches + the 1.49.0 release. All fail. I'm on Windows using gcc-4.6.1 mingw. I typically test using BJam. I also test using the gcc compiler directly with these flags: -Wall -mconsole -ftemplate-depth-512 -DNDEBUG -DNDEBUG -O3 -finline-functions -funroll-loops -Wfatal-errors -std=c++0x -static-libgcc -static-libstdc++ ========================================================================== Using built-in specs.

Very strange. I pasted your code into a file, and tried it on my Mac. I used trunk and release branches, gcc 4.2.1 and clang (from svn). All succeeded. Sample command: $ clang++ -I /Volumes/EyeFive/Marshall/Sources/boost/release junk.cpp $ -- Marshall

Looks like it's a known and mingw specific issue. https://svn.boost.org/trac/boost/ticket/6252 -- Olaf

Created ticket #6717. I'll fix it after dealing with iterator_range<> optimizations. -- Best regards, Antony Polukhin

The bug only appears when the compiler is very strict about name lookups in template contexts. GCC 4.6+ is stricter than 4.2. This particular bug is a missing include, which may be windows-specific.

Yes, and clang is (usually) stricter than gcc.

That would explain why I didn't see it. -- Marshall Marshall Clow Idio Software <mailto:mclow.lists@gmail.com> A.D. 1517: Martin Luther nails his 95 Theses to the church door and is promptly moderated down to (-1, Flamebait). -- Yu Suzuki
