[Dev-C++] MinGW port of gcc 3.2 and paths

[Luigi S. <gi...@li...>]

Hello all,

I've downloaded "new" MinGW gcc 3.2 to use it instead of "old" Mingw gcc 
2.95.2.

As I happen to use "gcc" from the command line, I've noticed the following 
change.

Say that "c:\test\hello.cpp" is the famous "hello world" program, also, 
suppose the semicolon, after the string literal "Hello world!\n", is missing.

When the command:

gcc -c c:\test\hello.cpp

is issued, one expects an error message of the type:

FILE:LINE: MESSAGE

where FILE is:
c:\test\hello.cpp      if "old" gcc is used
c:/test/hello.cpp      if "new" gcc is used

On Win98SE, I would like to have paths written in Windows style, and so 
tried a simple pipe:

gcc -c c:\test\hello.cpp | reverse_slashes

where "reverse_slashes" is a program turning all slashes into backslashes.

It does not work, since,  gcc prints error messages on the standard error 
stream


The next thing I thought of is:

gcc -c c:\test\hello.cpp 2>&1 | reverse_slashes

but that does not work either, because "command.com" is not "bash"!

Any suggestion is welcome.
TIA

Searched the MingW mailing list, got this:

------- Start -------
 Try Mumit Kahn's little redir utility. I think links to his site are in
 the mingw pages link section. with redir you can either redirect to a file
 or reirect to stdout and use less.

 Nicholas
------ Stop ------

I visited the site, and did a (very) superficial search, result: no `redir'
available. See if you can find it. Or google it, it should be archived
somewhere. I remember using it with DJGPP.

Thanks,

I've realized that my question was a bit OT, but you were so kind to answer 
it anyway.

I'm posting 2 possible solutions, so it will be stored in the ML archive.

1) REDIR
A google search using keys: "khan redir" yielded (first result) the 
directory: 
http://programming.ccp14.ac.uk/ftp-mirror/programming/mumit-khan/pub/khan/egcs/mingw32/misc/ 


There I found "redir.zip".

To solve my problem:
redir -eo gcc -c c:\test\hello.cpp | reverse_slashes

2) ERROUT
in the message http://sourceforge.net/mailarchive/message.php?msg_id=1166366
I found out about "errout", a program which may be downloaded using the 
link: http://www.simtel.net/pub/pd/12516.html

To solve my problem:
errout gcc -c c:\test\hello.cpp | reverse_slashes


Finally, here is the code for "reverse_slashes"

reverse_slashes
---------------
/* turn slashes ('/') into backslashes ('\\') */

#include <stdio.h>
int
main()
{
   int c;

   while ((c = getchar()) != EOF)
     putchar((c == '/') ? '\\' : c);

   return 0;
}
