Thread: Need help on Linux testing please

Can someone please help me test this program on Linux and verify the problems on why it doesn't compile while it does on Windows? I can't seem to install Wubi. That's why I really need help. Thank you in advance.

There are lots of erros here which shold be pretty obvious. I'm not sure about most compilers used in Windows, but I think gcc is pretty strict with regards to correct ANSI C, which many windows environments are not. (Correct me if I'm wrong, of course - I am, afer all, a C-newbie and mere dabbler myself.)

Thank you so much for the help. I am also a C newbie. I did the program on Windows but my professor wants it to work on Linux as well. She said it doesn't compile on Linux. I'm still in the process of installing Linux right now the reason why I still can't test it myself. Thank you for giving me the queue on where to start so I can try editing now.

Linux may be more strict than Windows... but C is C...

The name conflicts are warnings that you're clobbering the names of library functions. The solution for these would be to use a different name CurTime or such.

The variable "particulars" appears to be particularly problematic, so you need to figure out where and how to fix that. Looking at your code I see it's a struct. You have declared the struct but never created an instance of the struct...

Code:

/*structure definition*/
struct tparticulars {
  char *entry;
  int cost;
  char *period;
};
tparticulars particulars;

--OR--

/*structure definition*/
struct tparticulars {
  char *entry;
  int cost;
  char *period;
} particulars;

Most of the other errors look like syntax or undeclared variables (possibly resulting from syntax errors) I'd say your first pass at this would be to work out each error in turn and get the compiler happy...

To be honest, I'm surprised it compiled on Windows. You may want to check the reporting level of that compiler... It looks like you would have the same errors but for some reason it didn't report them. (Unless you're susing some massively braindead compiler...)

Honestly, I did not encounter any error on Windows. I am using Code Blocks 10.5 with MinGW..

I will try to make the Linux compiler happy..

Very odd... because the problem with "particulars" not being defined should have stopped *any* C compiler no matter what OS it was on...

Oh well, best of luck with the rest of it....

Rename your functions
void remove();
void time();
, there are standard-lib functions with the same name.
Also do it for
void access();
void login();
