Output from clang++ showing link failures
Running under the "Developer Command Prompt for VS2012", this program:
#include <iostream>
int main()
{
std::cout << "Hello, world\n";
}
compiles and runs fine with VC++ 2012, using the command lines:
<span class="quote">>cl hello.cpp
>hello</span >
using the command line:
<span class="quote">>clang++ hello.cpp</span >
It compiles OK, but the link fails with messages like:
hello-111ee3.o : error LNK2019: unresolved external symbol __ZSt4cout
referenced in function _main
Attached is the output file created by this command line:
<span class="quote">>clang++ -v hello.cpp >clang++.log 2>&1</span >
Feel free to contact me for more information.
