C++ error: stream.h: No such file or directory

[kdwoell]

Phase II of my ongoing drama to get some legacy C++ code running. As seen in a related post I'm not a developer, but a sysadmin.

Again, for some reason now matter how I format my post, I get this msg:
"You are only allowed to post URLs to other sites after you have made 15 posts or more."
(sigh) see attached file

try using iostream instead of iostream

Please disregard this post...I read the original post without my glasses..

The include statements you mention are identical. Perhaps you meant something else?

Why dont you give it what it wants? Google will get you stream.h.

What he meant was to use "#include <iostream>" instead of "#include <stream.h>".

Ok, slight progress; changing the include as follows:

#include <iostream>

/*#include <stream.h>*/
#include <math.h>

Results in this compile error:

[root@localhost up]# make 
g++ -DHAVE_CONFIG_H -Wall -g -I. -c atmosphere.cpp -o atmosphere.o
atmosphere.cpp: In function ‘void lower_atmosphere(double, double*, double*, double*)’:
atmosphere.cpp:134: error: ‘cerr’ was not declared in this scope
atmosphere.cpp:134: error: ‘endl’ was not declared in this scope
atmosphere.cpp:136: error: ‘exit’ was not declared in this scope
make: *** [atmosphere.o] Error 1
[root@localhost up]#

Which is an improvement over what I got yesterday:

g++ -DHAVE_CONFIG_H -Wall -g -I. -c atmosphere.cpp -o atmosphere.o
atmosphere.cpp:23:20: error: stream.h: No such file or directory
atmosphere.cpp: In function ‘void lower_atmosphere(double, double*, double*, double*)’:
atmosphere.cpp:133: error: ‘cerr’ was not declared in this scope
atmosphere.cpp:133: error: ‘endl’ was not declared in this scope
atmosphere.cpp:135: error: ‘exit’ was not declared in this scope
make: *** [atmosphere.o] Error 1

Final include statements in the .cpp that was holding up compilation:

#include <iostream>
using namespace std;
#include <cstdlib>
/*#include <stream.h>*/
#include <math.h>

Apparently from another forum #include <iostream> must be referenced to use the exit function in gcc 3.4., and iostream includes cstdlib. However in gcc 4.3 this dependency has been removed so you need to #include <cstdlib> to use exit.

It worked but an opinion from a veteran developer is welcome.

Many thanks for the assist!

I'd by no means call myself a "veteran", but what are you after an opinion on?

If your only problem was some mis-included files and a lack of "using namespace std", then doing what you did to get the code to compile is perfectly fine. Doing these sorts of things won't affect runtime behaviour, if that's what you're asking - they'll only allow the code to be compiled.
