如果你学习C++，请不要选择DevCpp

有网友发信给我，说使用DevCpp编译一个MTL库的测试程序出现一堆莫名其妙的错误。

DevCpp我听说过，以前也下载使用过，据说号称Windows平台下的gcc。结果我用DevCpp一编译网友的程序，感觉此编译器不堪大用。

网友的测试程序是这样的：

#include <iostream>
#include <boost/numeric/mtl/mtl.hpp>
int main(int argc, char* argv[])
{
    using namespace mtl;
    // Define dense vector of doubles with 10 elements all set to 0.0.
    dense_vector<double>   v(10, 0.0);
    // Set element 7 to 3.0.
    v[7]= 3.0;
    std::cout << "v is " << v << "/n";
    return 0;
}

结果出现莫名其妙的错误，说实话它的编译错误提示极为晦涩，我基本看不懂，只好以图为证：

但是我用VS 2008 + sp1编译这个程序，则一点问题都没有。看看网友怎么评论DevCpp的吧：

Get rid of Dev-C++ and download VC++ 2008 Express. If you have any difficulties after that, let us know.
Dev-C++ has not been supported by its creators for a long time. It is horribly out of date. You might be able to just update your version of the compiler and keep the IDE as-is, but you get a really good debugger integrated with VC++ 2008 Express that really blows the competition away.

所以在Windows平台下学习C++，我建议你选择VS 2005及更高版本的VS，或者选择开源的CodeBlocks。
