Problems with LCC-WIN32 compiler produced outputs
SkyIDE:
Hi,
The support for LCC-WIN32 is fully completed but after all the work I did, I just realised the compiler might be buggy. It's either me doing something wrong or it is the compiler itself.
I have a simple code:
--- ---#include <iostream.h>
int main()
{
int iVar = 0;
cout << "Simple LCC C++ Program\n";
for (int i = 0; i < 1000; i++)
cout << "Looping\n";
return 0;
}
Filename test.cpp
I use "lcc test.cpp -FoC:\test.exe"
You can also use "lcc test.cpp -o C:\test.exe" which is the standard
The problem is, the exe file is produced BUT the program does not run. When you type C:\test.exe it just starts and exits instantly without producing any output. I have completely no idea why it does this. Their web site is:
http://www.cs.virginia.edu/~lcc-win32/
I didn't see any -l(inking) options. I was hoping I will find something but nothing.

I reproduced the scenario copying and pasting your source code. When I run c:\test.exe it throws an exception:
--- ---C:\WINNT\system32\cmd.exe - c:\test.exe
The NTVDM-CPU has encountered an illegal instruction.

I doesn't matter which option I use to compile it.
If I change the code to:
--- ---#include <iostream.h>
int main()
{
cout << "Simple LCC C++ Program\n";
return 0;
}
then the program executes but freezes the command prompt...
Finally if I use -ansic or -pedantic switch I get a lot of warnings about obsolete code conventions. I'm not a C++ programmer, so that may be an issue here, but I can't tell you why :o
f0dder:
Hrm, has LCC-win32 finally added C++ support?
Last time I looked it was purely C, so I wonder how the above even compiles...
EDIT: hm, seems like LCC has some limited support for iostreams like stuff, even though it doesn't do C++?
Anyway, your problem (hinted by NTVDM error, which is something you get for DOS apps) is that LCC produces object file output, not executables - you need to manually link. Using "-Fo" just changes the name, not the contents, and windows then interprets the .exe (which is really a COFF object file) as a DOS .com app.
Ruffnekk:
LMAO, that *could* be the source of the problem here then :up:

Yes, sometimes I got exceptions too or it will just freeze.
