Thread: errors with bitset

I'm stumped as to why this code won't compile:

Code:

#include <bitset>
int main () {	
	std::bitset<8> b;	
	return 0;
}

I get a whole slew of errors from gcc (2.95.2)

Code:

\JFEAND~1\PROGS\bitset.cpp: In instantiation of `bitset<8,long unsigned int>':
\JFEAND~1\PROGS\bitset.cpp:3:   instantiated from here
\JFEAND~1\PROGS\bitset.cpp:3: `CHAR_BIT' was not declared in this scope
\JFEAND~1\PROGS\bitset.cpp:3: `CHAR_BIT' was not declared in this scope
\JFEAND~1\PROGS\bitset.cpp:3: template argument 1 is invalid
..\lib\gcc-lib\i386-mingw32\2.95.2\..\..\..\..\include\bitset:541: `CHAR_BIT' was not declared in this scope
..\lib\gcc-lib\i386-mingw32\2.95.2\..\..\..\..\include\bitset:541: `CHAR_BIT' was not declared in this scope
..\lib\gcc-lib\i386-mingw32\2.95.2\..\..\..\..\include\bitset:541: template argument 1 is invalid

and so on...
any ideas?

Is it std:: for bitset? I don't think it is. Take out the std:: and it should work.

EDIT: I was wrong. It works fine for me though. The above code.

hmm... perhaps my older version of gcc has some strange implementation of bitset

Try this, it prob won't make any difference, but throw in a 'using namespace std;', and take away the 'std::', and see if that works.

Nope, same errors.
Also tried adding using std::bitset.
I think it's just a problem with my version of gcc.

I get a ton of errors about "template argument 1 is invalid" and "CHAR_BIT' was not declared in this scope"

I'd say if you need to do this program to get dev of something which will allow the use of <bitset>.

Hmm I suppose October 27, 1999 (release date) was quite a while ago. It's probably time to upgrade.

The thing is that the build is integrated into a text editor called Jen's File Editor, and I don't know how to integrate the new compiler build.

The limits.h didn't work either.
It's ok, I switched over to Dev C++ with a newer version of gcc, and it works now.
It's a better IDE anyways.
Thanks for the help.
