c++ 模板参数问题

fallening

这样下载源代码：

1. git clone git://github.com/fengwang/random_variate_generator.git
   

复制代码

然后

1. cd random_variate_generator && make binomial_test
   

复制代码

错误如下：

1. g++ -c -O2 -Wall -g -std=c++0x -Iinclude  -o ./obj/binomial_test.o example/binomial_test.cc
   
2. example/binomial_test.cc: In function ‘int main()’:
   
3. example/binomial_test.cc:13:45: error: template argument 3 is invalid
   
4. example/binomial_test.cc:13:49: error: invalid type in declaration before ‘(’ token
   
5. example/binomial_test.cc:13:58: error: initializer expression list treated as compound expression
   
6. example/binomial_test.cc:13:58: warning: left-hand operand of comma has no effect
   
7. example/binomial_test.cc:16:14: error: request for member ‘begin’ in ‘vg’, which is of non-class type ‘int’
   
8. example/binomial_test.cc:16:26: error: request for member ‘begin’ in ‘vg’, which is of non-class type ‘int’
   
9. example/binomial_test.cc:18:31: error: request for member ‘begin’ in ‘vg’, which is of non-class type ‘int’
   
10. example/binomial_test.cc:18:43: error: request for member ‘begin’ in ‘vg’, which is of non-class type ‘int’
    
11. example/binomial_test.cc:18:59: error: unable to deduce ‘auto’ from ‘<expression error>’
    
12. make: *** [binomial_test.o] Error 1

gcc 4.5.1 编译错误信息如上，icc 11.1以及ms vc10均可通过。

解决了，原因在于<algorithm>在c++0x中隐式包含了<random>，两边的mt19937冲突。

(c++是一个恶心的东西。 让人无法知道include一个文件后，会引入哪些名字。就算有了名字空间，一样是混乱的。 )
