Trouble with c-string functions.

I've included cstdio library in all .cpp files. In main.cpp i can use strlen but on the contrary in rest .cpp files i can't do this.

	Source code
1 2 3 4 5 6 7 8	// some.cpp #include <iostream> #include <cstdio> using namespace std; int sdfsd() { strlen(); // compilier don't know about this function }

	Source code
1 2 3 4 5 6 7	// main.cpp #include <cstdio> int main(int argc, char *argv[]) { strlen(); // allright. }

I've made new project yet - no results.

my opinion is "never" use such as:

	Source code
1	using namespace std;

which make tings less clear

I write "never" because "always / never do something rules" are not good rules
it's just my opinion

what do you mean 'compiler doesnt know'?

Show exact compiler error message, and exact COMPLETE code that gives that error.

If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.

I've attached screenshot of problem.
http://rghost.net/37615951 the whole project, it's the most helpful thing in my situation.

non-working code is more than 10 000 characters. It is in a flex.cpp file.
At 12 str - inclusion stdio.h;
at 795 str - using of strcpy and small above strlen.

I think the reason is in the linking or smth the same, but not exactly in the library.

your problem seems to be in .l / .y file (??? #line 75 "dscrptFlex_Perl.txt")
which is missing string.h

Yes, that's it.
But i still don't understand why i was needed to string.h ?

Quoted from "Nicolas SOUCHON"

which is missing string.h

<string.h> is not standard c++. correct is <cstring>

not sure the generated parser is C++

even
sure the generated parser is not C++

so
what could be the problem including string.h

@KBAC
whithout the code of the parser, how could I tell why you need it
but sure generated parser uses, at least, strcpy
