[Bug c++/29596] overloaded function not found
--- Comment #13 from again at gmx dot de 2006-10-30 17:12 ---
(In reply to comment #11)
I believe the testcase is invalid.
You're right, therefore I'm closing this bug. The author of the Boost.Lambda
library, Jaakko Järvi, kindly pointed my to a section of the library
documentation, where it is written that arguments to lambda functions can't be
non-const rvalues[1].
The following patch corrects the test case:
--- test2.cpp.~1~ 2006-10-27 11:02:14.0 +0200
+++ test2.cpp 2006-10-30 18:05:06.0 +0100
@@ -11,6 +11,8 @@
int main()
{
int a = 1, b = 2;
-std::cout (boost::lambda::_1)(std::make_pair(a, b)) std::endl;
+std::cout
+ (boost::lambda::_1)(boost::lambda::make_const(std::make_pair(a,
b)))
+ std::endl;
return 0;
}
I don't know why it compiles cleanly on VC++, though.
Best regards
Christian
