Re: pipe data form windows program to cygwin program
Hi
bob thanks for your help,
i solve the problem bny using only windows functions to have a pipe and
that is working well. It seems that posix and windows doesn't work well
together.

i think i did, but even if i didn't the fact that the program exit
normally will close all open handles under windows, won't it ?
It's true that all open handles for the parent process will be closed
on exit. However, if handles for the write side of the pipe were
passed to the child process, and any of them remain open, then that's
a problem. This appears to be the case for your sample program.
Here are some suggestions:
-- If you only need to write out some compressed data, try linking
with zlib and calling one of the gzip functions: some examples
are provided with the zlib source distribution. This is simple
(no pipes or subprocesses), efficient, and effective.
-- If you really do need a pipe to a subprocess, consider using
popen(), which does all of the work for you.
-- If for some reason you need to do all of the pipe and process
creation stuff yourself, be sure to close all of the unneeded
file descriptors in the child process as well as in the parent
process. The usual technique looks something like this:
int pfds[2];// pipe file descriptors
pipe(pfds); // make the pipe
if (fork() == 0) {
// child
// connect stdin to read side of pipe
dup2(pfds[0], STDIN_FILENO);
// close unneeded pipe descriptors
close(pfds[0]);
close(pfds[1]);
execlp(gzip, ...);
} else {
// parent
// connect stdout to write side of pipe
dup2(pfds[1], STDOUT_FILENO);
// close unneeded pipe descriptors
close(pfds[0]);
close(pfds[1]);
// write to stdout
// close stdout, or exit
}
Alternately, the parent could just write to pfds[1], the write side
of the pipe, if you don't want or need to mess with stdout. But it's
still important to close pfds[0], the read side of the pipe, in the
parent process.
Either way, there are no stray open file descriptors for the pipe
in any process, so when the parent closes the write side of the pipe,
the child should see EOF on the read side.
One final suggestion: I'd try to avoid mixing the win32 and posix APIs.
Life is complicated enough without trying to deal with win32 HANDLEs
and posix (int) file descriptors at the same time, or using functions
like DuplicateHandle() and dup2() in the same program.
HTH ...

the program is going great but at the end gzip( or you can try with cat

I thought that the cleanup thread of the cygserver was supposed to clean those but i have to remove them myself. Is this a normal behavior ? Is there something to configure in cygserver to clean those ? This is normal behaviour. SYSV IPC is designed to keep the IPC elements intact even if no process is accessing them. If you want to get rid of them, then you have to do this by using the appropriate IPC_RMID control call: msgctl (msgid, IPC_RMID, NULL); semctl (semid, 0, IPC_RMID); shmctl (shmid, IPC_RMID, NULL); Thank you, i will try to find a way to call shmctl from the last thread running. If you're creating an application which needs shared memory only on runtime, which should disappear when the last application using it exits, consider to use simple mmap calls. It's way easier than having to run cygserver.

Re: ncurses not found when compiling various packages
you should ckeck if there is links between ncurses and curses files. ex: curses.h - ncurses.h etc if not you should reinstall libncurses bertrand Thorsten Kampe a écrit: Hi, I often get the message from configure scripts for applications that are curses-based that no ncurses could be found (although it actually is installed[1] and many applications happily use it) What's going wrong and how can I point the configure script to my ncurses dlls?

Under linux i crypt the string with a salt and then i have to remove the first characters to remove the salt from the result string. But under cygwin it seems that i only have a 13 char string with no salt at the beginning and this result string is completely different from the linux result string with the same input. Does anyone know a way to solve that -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
Re: How To Export NFS?
Hello i think that's not the good way to run portmap nfsd and mountd directly you should install them as windows services. there is a script with cygwin called nfs-server-config which will configure that for you: install the services and generate default config files, you will then be able to add what you want to /etc/exports and then restart the services with thoses commands: to stop the services: cygrunsrv -E portmap cygrunsrv -E mountd cygrunsrv -E nfsd to start the services: cygrunsrv -S portmap cygrunsrv -S mountd cygrunsrv -S nfsd then i think it would have more chance to work Jack Polimer a écrit: Begin Disclaimer: The following searches produced nothing useful...

libiberty and getopt
Hi,
I need to compile a program using libiberty.a and the function
getopt_long. When compiling with the flag -liberty my program crash
because it don't take the right arguments from the command line. But
without libiberty this part work before.
i made a small program showing that problem, if anyone has an idea ?
i'm using the latest cygwin from the installer ,gcc-3.3.1 and ld 2.15.90
20040312
thanks
You can find next my source code for the test program and the result i
have with it.
My test program:
/*begin of argu.c*/
#include unistd.h
#include getopt.h
#include ctype.h
#include stdio.h
int main(int argc, char **argv) {
struct option long_opts[] = {
{v, 1, 0, 'v'},
{no-v, 0, 0, 'V'},
{k, 1, 0, 'k'},
{no-k, 0, 0, 'K'},
{l, 1, 0, 'l'},
{no-l, 0, 0, 'L'},
{0, 0, 0, 0}
};
int c;
while ((c = getopt_long(argc, argv, v:Vk:Kl:L:,
long_opts, NULL)) != EOF) {
switch(c) {
case 'v':
printf(v %s\n,optarg);
break;
case 'V':
printf(V\n);
break;
case 'k':
printf(k %s\n,optarg);
break;
case 'K':
printf(K\n);
break;
case 'l':
printf(l %s\n,optarg);
break;
case 'L':
printf(L\n);
break;
case '?':
printf(other:%c\n,c);
}
}
printf(argc=%d , optind=%d ,
file=%s\n,argc,optind,argcoptind?*(argv+optind):none);
return 0;
}
/*end of argu.c*/
when you compile it with : gcc argu.c -o argu.exe it works:
$ ./argu.exe -v abc -K test
v abc
K
argc=5 , optind=4 , file=test
but when you compile it with gcc argu.c -o argu.exe -liberty it gives:
$ ./argu.exe -v abc -K test
v (null)
K
argc=5 , optind=1 , file=-v

Re: libiberty and getopt
Hi again,
i just find the solution to my problem
in fact it seems that adding:
extern int optind;
extern char *optarg;
solve the problem. The compiler then auto-import these variables and it
is working after. This problem doesn't seem to exist under linux but it
could be a difference in versions between my linux and my cygwin.

Re: stat()/lstat() problem (?)
ZXPLESPAC001, Ext a écrit:
Hi,
here is my question/problem (see the example program below):
-//
#include stdio.h
#include sys/types.h
#include sys/stat.h
#include errno.h
static int is_dir(char * dr)
{
struct stat st;
if(stat(dr, st) == -1)
{
perror(stat);
return -1;
}
if(lstat(dr, st) == -1)
{
perror(lstat);
return -1;
}
}
int main(int argc,char **argv)
{
int rc;
rc=is_dir(//bin);
rc=is_dir(/bin);
}
-//
With my version of cygwin(Windows NT Ver 4.0 Build 1381 Service Pack 6 -
cygwin 1.5.9-1)
the first call to is_dir() produces an error(stat: No such file or
directory)
BUT the same code was compiled and run on Linux (RH9) and Sun (Solaris2.8)
and
produces no errors !!
The question is:
- is the behavior on Linux/Solaris normal ? I fact there ain't a '//bin'
only a '/bin',
but even all the shells treat them as representing the same path (BTW 'cd
//bin' on
cygwin/bash doesn't work ...)
this is a normal error under cygwin, you should look at the FAQ: //
refers to network places
- is it an error in cygwin ? Did all pathes (oops is my english very clear
?) have to
treat dupplicated '/' as single '/' ? Is the notion of a pathname normalized
somewhere
(maybe posix ?) ?
you should remove all // under cygwin to avoid those errors

Re: need loadkeys --mktable under cygwin
I found a solution i downloaded kbd-0.99 it doesn't compile under cygwin but if you take the files: loadkeys.y ksyms.c findfile.c getfd.c than you take kd.h wait.h and keyboard.h from a linux kernel and you can compile a simple loadkeys for cygwin to use to compile a kernel. i made this with those commands (i.m using a cross compiler): bison -y loadkeys.y mv -f y.tab.c loadkeys.c flex -8 -t analyze.l analyze.c i686-pc-cygwin-gcc -c -O2 -DDATADIR=\/usr/share/kbd\ loadkeys.c i686-pc-cygwin-gcc -c -Wall -O2 -DDATADIR=\/usr/share/kbd\ ksyms.c i686-pc-cygwin-gcc -c -Wall -O2 -DDATADIR=\/usr/share/kbd\ findfile.c i686-pc-cygwin-gcc -c -Wall -O2 -DDATADIR=\/usr/share/kbd\ getfd.c i686-pc-cygwin-gcc -s loadkeys.o ksyms.o findfile.o getfd.o -o loadkeys Igor Pechtchanski a écrit: On Tue, 30 Mar 2004, bertrand marquis wrote: Hello i.m trying to build the kernel under cygwin with a cross compiler (host=cygwin target=i386-linux) and it seems that the kernel need the loadkeys program to be build. I have tried to find it but it seems that it don't exist. Does anyone know a solution for that problem ? thanks Yep. It's called porting. :-) Seriously, though, looking at the man page for loadkeys, it doesn't seem too relevant for Cygwin. In particular, the entry for --mktable says: CREATE KERNEL SOURCE TABLE If the -m (or --mktable ) option is given loadkeys prints to the standard output a file that may be used as /usr/src/linux/drivers/char/defkeymap.c, specifying the default key bindings for a kernel (and does not modify the current keymap). Sounds like the kernel is not very cross-compilation friendly (i.e., it's expected to be compiled *on a Linux machine*). One solution is to create a loadkeys script that accepts only one option (--mktable) and prints out pre-defined text... Alternatively, contact the authors of the code and notify them that their code doesn't build on Cygwin (and probably won't on OpenBSD, either).
