Re: General problems creating executables.

["David Westbury" <David dot Westbury at ipaper dot com>]

David,

I haven't had a problem with "hello world".  Here's my program and the gcc
string I used.

#include <stdio.h>

main()
{
     printf("hello world\n");
}

Here's how I compiled it:

gcc  hello.c   -o hello

When I run the above gcc command I get the following executable:

hello.exe

I run this by typing "hello.exe" at the command promt. It prints "hello
world" on my screen.

Perhaps you could use "-v" with gcc to get more verbose output.

I have in fact run into the problem you're having but only when trying to
link against a DLL.
Then I get no warnings, no errors and no executable. I don't yet know why.

Wish I could tell you more.  I apologize for all the help I've given you
8^).

David

David,

Thanks for the info.  I was wondering why such simple-sounding information
seemed so hard to find in the faq...

Have you gotten gcc to make executables successfully?  Or have you given
up on compiling, for now?

Thanks,
David
