what is possbole cause?

[wenmang]

I am using SGI STL for string class. When I do following:
std::string("hi");

Comipler complains:
"myTest.C", line 10: error: namespace "std" has no member "string"
std::string str("myTest");
^

"myTest.C", line 10: error: expected a ";"
std::string str("myTest");
^

make: *** [myTest.o] Error 1

I do make depend, it clearly states:
"myTest.o: /usr/local/include/sgistl/string"

vi "/usr/local/include/sgistl/string", I can see std namespace is
defined, why does
compiler complains then?

thanks.

Post your code so we can help.

If this doesn't compile, I think you need
to update your compiler package.

So? Does it (or, do you) know where the <string> is being pulled
from? BTW, make sure you don't put the '.h' there (sometimes some
folks just assume that <string> and <string.h> are the same thing.
They are most certainly aren't.

@g44g2000cwa.googlegroups.com:

std::string str("myTest");

#include <string>

std::string var = "blah";

if you then need to use the string in a place that requires a char*
then use

var.c_str()

example:

std::string var = "hello";
MessageBox(NULL,var.c_str(),"Message",MB_OK | MB_ICONINFORMATION);
Right?

I think that I am mentally challenged. We are using SCO compiler which
only supports pre-std C++, but on our development platform(UnixWare
7.1), we have g++ and sgi stuff(std C++) installed.
The error I mentioned earlier, pops up when native SCO C++ compiler is
used, and I have no idea how this compiler can compile SGI stuffs.

Please, post a minimal piece of code that reproduces the problem. Without
seeing what you are doing, it is impossible to tell what is going wrong.

this is piece of code I am trying to compile:

#include <string>

int main(int argc, char ** argv)
{
std::string str("myTest");

return 0;
}

It may be that you have an earlier version that doesn't used std::
so try and remove that and see what it does, and then decide if you
want that version of the compiler/lib or not.

Are you sure that the compiler is treating this as a C++ file? I know
that on Unix systems there is a difference between ".c" and ".C", but
I'm not sure if that is enough to make the compiler treat it the right
way.

Yes, I am sure.

By peeking into the sgi file named string, I can see following:
__STL_BEGIN_NAMESPACE
:
:
__STL_END_NAMESPACE

__STL_BEGIN_NAMESPACE defined as :
# define __STL_BEGIN_NAMESPACE namespace std {

Like I mentioned before, I did "make depend", it clearly indicates that
sgi string header file is included for the test program, I just don't
get why it won't compile.

Maybe "make depend" is finding a different include file than the
compiler is actually using.

Dump the preprocessor output to a file (-E with g++) and look for the
definition of std::string. Then you'll know for sure.

It may be looking at something different.
Instead, you can do two things to verify: run with -M and it will
dump out what it sees (you say gcc right?), and also use -E and
see what the #line directives and such is going on.
