[Bug c++/29596] overloaded function not found

(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

However, my initial testcase (attachment #12493) does still not compile, so it
seems I have simplified it wrongly.  I will check this back and reopen the bug
accordingly.

[Bug c++/29596] New: overloaded function not found

2006-10-25 Thread again at gmx dot de 
Please find attached a sample program, which does not compile.

Unfortunately this program depends on boost.  I use the current boost version
1.33.1.  The include files algorithm and iostream are the ones belonging to
gcc-4.1.1.

Remark to test.cpp:23:
std::cout  boost::lambda::_1  '\n'

This should find the overloaded operator defined in boost/tuple_io.hpp.
