Hi all,
I have upgraded to the latest cygwin this morning and
I can not anymore run my programs that use ifstream to
read input files. It crashes giving segmentation
fault. When I ran strace, I found that the actually
fails in mmap.cc complaining STATUS_ACCESS_VIOLATION.
Here's the simple code I ran. Anybody have any clues?
Interestingly the following programs works fine with
-mno-cygwin option which unfortunaty I can not use for
my application.
# include <iostream>
# include <fstream>
int main(int argc, char *argv[])
{
char ch;
if (argc < 2)
{
cout << "Usage: a.out file_name" << endl;
}
ifstream is(argv[1], ios::in);
while (! is.eof())
{
is.get(ch);
cout << ch;
}
is.close();
return 0;
}
Thanks,
- Vijay

Vijay,
Please (re)read <http://cygwin.com/problems.html>, especially the part
about attaching (as an uncompressed text *attachment*) the output of
"cygcheck -svr". FYI, you must be using the earlier version of g++ as
well, since g++ 3.2 complains on compiling your program (you need to
insert "using namespace std;" before main() for it to compile).
FWIW, your program works just fine on Cygwin 1.5.3-1 (as a datapoint). I
didn't install 1.5.4 yet, so can't try reproducing it there.
Igor

Sorry for providing all the information needed. Ok,
let me give it another short.
I am using gcc 2.95.3-10 and compiling the program
using /usr/bin/g++-2.exe and here's the output from
cygcheck -svr

Could someone tell me what I am doing wrong or do I have something set up wrong
in my install. I am simply trying to learn but if I put this in a file called
first.cpp:
//
// this is first test application
//
#include <iostream>
using namespace std;
int main()
{
cout << "Welcome to C++\r\n";
cout << "Hope you learn a lot\r\n";
}
and then do:
/usr/develop/src/learning
$ gcc -g -o ./debug/first.exe ./first.cpp
I get this for output - not too pretty.
/tmp/ccRHUQ8U.o(.text+0x49): In function `main':
/usr/develop/src/learning/first.cpp:11: undefined reference to `std::cout'

$
And it doesn't get any better if I try it with -mno-cygwin. I can compile the
Cygwin cvs tree and the setup cvs tree but those you makefiles.
Any help or a pointer would be appreciated.

g++ !
Oh, and in your output, get rid of the \n, use
cout << "foo" << endl;
instead.
Cheers,

To compile C++ program one should use g++ (not gcc).
For instance,
$ g++ -g -o ./debug/first.exe ./first.cpp
To compile C program one should use gcc.
For instance,
$ gcc -g -o ./debug/first2.exe ./first2.c

Now, this is off topic, it belongs in nntp://comp.sys.lang.c++ or some
such... but anyway:
To make it more verbose:
This makes your code easier to port (take to other environments).
End of line, i.e. \n and \r in combinations, depends on which OS you are
using... "endl" is always right.
BTW: I find code that looks like this a lot more readable:
cout
<< "Welcome to C++" << endl
<< "Hope you learn a lot" << endl
;
But, I guess, this might cause some sensitive people to start grumblin' ;-)

Thanks Rob,
That was sort of a duh wasn't it. I guess I need some more reading - gcc shows
in man as the GNU C and C++ compiler and if I do a man g++ I get the manual for
gcc or if I do man "g++". Thought that was the right one - even though I have
seen both.
Off to the books.

Brian,
FYI (and to get this into the archives), if there's only one input source
file, you can simply use the default make rules, and they should do the
right thing, i.e., if you say "make first", it should invoke the right
compiler to process first.cpp (at least you'll see what the right compiler
is). If you want to pass extra flags, try "make CXXFLAGS=-g CFLAGS=-g
first"). Putting the file in a different directory, as in your case, will
not be as easy, though...
