please help : Error: Unexpected type name
HI all, when I try to compile the example code only use boost head-file in SunOS :
#include
#include <iostream> #include <iterator> #include <algorithm> int main() { using namespace boost::lambda; typedef std::istream_iterator<int> in;
std::for_each( in(std::cin), in(), std::cout << (_1 * 3) << " " ); }
I get many errors like 'Unexpected type name', the first one is :
CC -g -I../. -c -o main.o main.C ".././boost/lambda/detail/function_adaptors.hpp", line 203: Error: Unexpected type name "boost::lambda::Arg1" encountered.
could someone give a hand.

HI Bruce , it's already in the code .
using namespace boost::lambda; typedef std::istream_iterator<int> in;
std::for_each( in(std::cin), in(), std::cout << (_1 * 3) << " " ); }

Understood. I am advocating that you fully qualify the _1 at the call site as you might be running afoul of a clash with some other _1s. Sun, Xiuxin wrote:

Still get same errors even after comment out following lines that the
possibility of _1 error could be excluded.

Can I just be absolutely clear here - Do you mean that compiling this code:-
#include
yes, the file relation of my test code is :
main.C is placed in .../boost_1_35_0/test/
boost is in .../boost_1_35_0/
CC version : Forte Developer 7 C++ 5.4 Patch 111715-18 2006/11/02
and errors are :
CC -g -I../. -c -o main.o main.C
".././boost/lambda/detail/function_adaptors.hpp", line 203: Error:
Unexpected type name "boost::lambda::Arg1" encountered.
".././boost/lambda/detail/function_adaptors.hpp", line 203: Error:

You mentioned in your earlier post that you were using Sun Forte 7 compiler. AFAIK, that is ancient; boost 1.34 needs at least Sun Studio 11, and boost 1.35 does not support Sun's C++ compiler at all :(
