Hello.

I am having trouble building a simple project that uses one of the
Standard C++ Library's IO facilities. The following is a stripped-down
version that illustrates the problem:

[beginning of sample program]
#include <fstream>

int main(int argc, char* argv[])
{
  std::ofstream saida("saida.txt");
}
[end of sample program]

This is the makefile I am using to build it:

[beginning of makefile]
proj = teste
libspadrao = kernel32.lib msvcrt.lib msvcprt.lib

opcomp = /c /EHs /G7 /WL /MT
oplink = /incremental:no /subsystem:windows /release /nodefaultlib
/verbose:lib

$(proj).exe: $(proj).obj
  link $(oplink) $(libspadrao) $(proj).obj

$(proj).obj: $(proj).cpp
  cl $(opcomp) $(proj).cpp
[end of makefile]

And finally, this is the undesirable output I get from the linker. I
tried using dumpbin in order to find where the missing symbols are
defined, but to no avail.

[beginning of relevant linker output]

quadrado.exe : fatal error LNK1120: 4 unresolved externals

What is missing in my build setting? Shouldn't msvcprt.lib include the
C++'s IO-related symbols which are said to be missing?

Thank you,
