Hi all, Here is a very simple test program I am compiling with
g++ -mno-cygwin -c test.cpp -o test.exe
--- snip ---
#include <iostream>
int main (int argc, char *argv[])
{
int frog = 10;
int blob = 20;
for ( int i = 0; i < 10; i++ )
{
std::cout << "hello world" << frog << " " << blob << std::endl;
frog += blob;
}
return(0);
}
--- snip ---
When I run this from a command.com style window, a very strange thing
happens - the text cursor starts jumping about the screen in a repeated
pattern (I'm not joking, I thought it was a virus or something at first).
When I run it from rxvt, rxvt just freezes on me after I press ctrl-c.
In both cases I have to use the task manager to close down a task called
ntvdm.exe which is using up 50% of the cpu time. If I end that task the
prompt returns to rxvt (or the command.com shell).
cygcheck -sv output is attached.
Regards

I would suspect that you are not running the program as ./test and are,
instead running some other random "program" named test.
It's usually a good idea not to use 'test' as a command name since UNIX
systems have a test program installed in /usr/bin.

But the man says he gets other responses in command.com (not bash or rxvt)
these don't have the path problem do they?
I thought window$/do$ always checks it's current directory first?

I thought of that before posting to the group, and renamed my executable to
my_test_is_mine_only.exe
Same results.
Its the oddest thing I've ever seen and reminded me (not in a good way) of
DOS days of old :-), any ideas?

Sorry to waste everybody's time, but I'm really confused now. I re-compiled
the program today with the *exact* same command line arguments, the only
difference is that I've rebooted the computer. The program now works
*fine*!!
The order of events:
1> I logged in as Administrator and ran cygwin's setup.exe
2> I installed all the latest Exp stuff, setup didn't say I needed to
reboot, so I didn't.
3> I logged out, logged back in as myself
4> Tried using the -mno-cygwin options and hit the problem posted yesterday.
5> Shutdown win2k and went home
6> First thing this morning, tried *exactly the same thing*, and it works.
:-?
I think I'll reboot no matter what Setup reckons in the future. :-)

What OS are you running? If it's NT/2K setup can't replace in use files,
and thats when it will warn. If setup doesn't warn you, then you don't
need to reboot.

You need the gcc-mingw package too if you want to use -mno-cygwin

Ok, installed it. It compiles but :
$ ./cpplus.exe
never returns and only moves the cursor in a random place.
it must be killed (ctrl-c has no effect) and the terminal isn't
restored. reset must be invoked to have a normal bash after running it.

This is what I was getting! I'm glad it wasn't just my imagination.
But after a reboot (or a day not looking at it), I re-compiled it and it
worked fine.

That sounds like the problems reported (which this thread is about).
However, I have no problems here (NT4 SP6a & latest Cygwin stuff).
I'm using rxvt as shell with bash.

sounds like hiho is a script file or something there mate.. backquotes
shouldn't exist in C++ programs.. and there aren't any in the program I
included.

It is the snippet you posted, not more and not less... just called it
hiho because we saw that 'test' may be a bad name. But it is really
interesting what happens if you use an executable and its name is
'hiho' without the postfix .exe:
$ g++ -mno-cygwin -c hiho.cpp -o hiho
$ chmod a+x hiho
$ ./hiho
./hiho: 9: Syntax error: EOF in backquote substitution
$ mv hiho hiho.exe
$ ./hiho
bash: ./hiho: No such file or directory
$ ./hiho.exe
bash: ./hiho.exe: No such file or directory

I guess this result isn't much better;)

That's very odd behaviour! What else is in your current directory? Is
there a hiho.exe.exe? :-)

No, I got 'hiho' after compiling with '-o hiho', after moving this to
'hiho.exe' I got the error.

I have some of these too... how do I know if the partitions are
nonexec or not? No hint when I type in 'mount'. I would like to
see a trigger in setup.exe to decide whether I want to have a shared
drive to be exec or nonexec.

Rather than assume that mount is not providing you with the information,
it would be better to double check that you actually do have noexec
directories. The mount command does provide appropriate information if
a directory is mounted with the -E option.
>I would like to see a trigger in setup.exe to decide whether I want to

No way! You'd like setup.exe to act differently or do something for
you??? What a novel concept.
I don't know why the setup maintainers are so insistent on thwarting the
desires of people who want to run it. I have my theories, of course...

I'd be interested in how you could see any quirks on linux with the
-mno-cygwin option. It seems to me that this would produce a program
that doesn't run at all, unless, maybe, you have wine installed or
something.

I was just testing the C++ code. No -mno-cygwin at all.
The quirks were having an unrunnable file foo.
Then I realised where I was in the fs, moved it out of there, and voila,
no problem.
However I think one interesting thing has come up - is the cygwin gcc
3.1.x patched to generate foo.exe when passed '-o foo' ?

gcc 3.1.x and every native cygwin gcc that I have used in the last four
years.

Gerrit,
If you remove the ".exe" extension from a binary executable, it gets
treated like a script. Very few binaries are valid script files...
When you use the "-c" option, you suppress the whole linking phase. The
output, regardless of its extension, is not a binary executable, it's an
object file. If you run the "file" command on your "hiho.exe" or its
earlier name: "hiho," you'll see something like this:
% g++ -c hiho.cpp
% file hiho.o
hiho.o: 80386 COFF executable not stripped - version 30821
Contrast:
% g++ hiho.cpp -o hiho.exe
% file hiho.exe
hiho.exe: MS Windows PE Intel 80386 console executable not relocatable
Lastly:
% g++ -mno-cygwin hiho.cpp -o hiho.exe
hiho.cpp:2: iostream: No such file or directory

Hallo Randall,
Then only the syntax of this command was wrong:
>>$ g++ -mno-cygwin -c hiho.cpp -o hiho
With the correct syntax it looks ok:
$ g++ -mno-cygwin -o hiho.exe hiho.cpp
$ ./hiho.exe
hello world10 20
hello world30 20
hello world50 20
hello world70 20
hello world90 20
hello world110 20
hello world130 20
hello world150 20
hello world170 20
hello world190 20
I just useed copy & paste (without using my brain;).

Wow, all of this traffic and Randall is the first, AFAICT, to notice
that someone was using the -c option incorrectly. When I did my test
case, I actually correctly did not use the -c option to try to create an
executable and I never noticed the cockpit error.
There are something on the order of 22 messages in this thread and it
looks like only one person actually noticed the obvious problem.

I suspect that this particular problem is probably due to the fact that
you haven't installed the latest gcc-mingw package.

This thread is not dead.
The result of this shows that Cygwin can at the moment be told to
execute code without having a correct executable file (also COFF
format).
Cygwin should have detected a non-executable file and
have refused to launch it.
What happens here on NT:
if you use incorrect syntax by appending .exe in g++ cmd :
$ g++ -mno-cygwin -c cpplus.cpp -o cpplus.exe ; g++ -mno-cygwin -c
cpplus.cpp -o cpplus
$ ls -l cpplus cpplus.exe
-rw-r--r-- 1 Nom 544 1855 Jul 21 20:38 cpplus
-rwxr-xr-x 1 Nom 544 1855 Jul 21 20:41 cpplus.exe
finally tring to launch it:
$ ./cpplus
BASH: ./cpplus: Permission denied
$ ./cpplus.exe
runs and hangs. (note that under Windows ME it doesn't run,saying
permission denied though it's detected as executable by ls).
two problems:
- ls should show non executable file (problem in cygwin filesystem /ls
excutable detection routine)
- incorrect code can be launched on NT systems.

Actually if it was going to happen anywhere, it is ash that should have
detected it, not cygwin. Since windows (without ntsec) has no concept
of an executable bit, unrecognized files are passed directly to /bin/sh.
This is similar to unix, except on unix there is the added protection
of the executable bit. If the file doesn't have the executable bit set
then it is actually never forwarded to /bin/sh by the OS.

I don't see this behavior on XP. Attempting to run the non-executable
program (cpplus in this case) either hangs or gives strange messages.
It's possible that, in your case, bash notices the lack of executable
bit and never passes things on for execution. I don't know why your
experience differs but I am not going to lose sleep over it.

If the file has a .exe extension, it is assumed to be executable. This
is by design. We've had two threads in the last week complaining about
cygwin being slow. Every time we open a file to check to see if it's
executable we slow things down.

I've explained what is happening above.
As usual, I'd welcome patches to ash to fix this behavior. I'm not
concerned about this enough to devote any time to it myself.

Sorry about the wild goose chase but it was very odd behaviour.
In 10 years of using gcc I've never come across the "trying to execute an
.obj file causes crash" problem before, but I was using linux and as you
say, the executable bit wouldn't have got set and I'd have noticed
immediately.
It seems strange that in this day and age, a .exe wouldn't have any info in
it to prevent something that is not an .exe from being run. To this extent,
any user can rename any file a .exe and cause his/her machine to do very
unstable things, that's just bad all round. Good old windows strikes again.
Thanks for tracking it down.
