| I am sorry, your description has me completely confused. Note, when
| compiling, 'gcc' cannot correctly link c++ code; you must use
| 'g++' - so 'gcc' and 'g++' are two different beasts, even though
| they come in the same package (which as a whole is called 'GCC').
I use g++; I've got an advice to try gcc, but it did not help. The code is
written in C++.
|
| 'does not see iostream.h' could mean any number of things:
|
| (a) The code:
| #include <iostream.h>
| results in an error such as:
| test.cc:1: iostream.h: No such file or directory
|
| This usually means GCC is incorrectly or incompletely
| installed. One possibility is that only the C compiler ('gcc')
| was installed, and the C++ compiler ('g++') was not.
In my case g++ works well, gcc has links problems.
|
| (b) code such as:
|
| #include<iostream>
|
| int main()
| {
| cout << "Hello world!" << endl;
| }
| results in errors such as:
| incl.cc:5: error: 'cout' was not declared in this scope
|
| This is becuase C++ 1998 requires cout and endl be called
| 'std::cout' and 'std::endl', or that a proper using directives
| such as 'using namespace std;' be used.
|
| (c) any number of other things.
This error is not my case - I had <iostream.h>. Let's not use gcc, as the
g++ was the compiler for this project in 2000-2001.
|
| If you can, please include a short-but-complete code example, which is
| sufficient to cause the problem, and paste (do not summarize) the
| error messages you get.
I am concentrating on this.

| Why do you think extern "C" {} has anything to do with your problem?

|
| Did your existing executable suddenly stop working? If it didn't, and
| you aren't a programmer, why are you trying to recompile it?
| (There is nothing wrong with non-programmers recompiling code, but
| when it does not compile, they usually lack the vocabulary and /
| or concepts necessary to describe the problems encountered, or to
| apply the suggestions of people (invariably programmers) trying to
| help.)
My existing executable doesn't give enough digits - I will need very small
changes if I can recompile the project (I have not done any changes yet).
I understand the mathematical part of the code well, but not the part
associated with flex.

Thanks you, I will try to provide code examples.

I started the thread with
