program startup problem
Hi, I'm having a problem where a program of mine is crashing with a sigsegv, but I'm clueless as to why it happens. The same source runs fine on a variety of machines, including my cygwin setup at home, but a friend is seeing the following segfault with backtrace: (gdb) run H2O.inp Starting program: /home/psd127/bin/cp2k.sopt H2O.inp Loaded symbols for /cygdrive/c/WINDOWS/system32/ntdll.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/kernel32.dll Loaded symbols for /usr/bin/cygwin1.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/advapi32.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/rpcrt4.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/ws2_32.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/msvcrt.dll Loaded symbols for /cygdrive/c/WINDOWS/system32/ws2help.dll 5 [main] cp2k.sopt 1128 _cygtls::handle_exceptions: Exception: STATUS_ACCESS_VIOLATION 423 [main] cp2k.sopt 1128 open_stackdumpfile: Dumping stack trace to cp2k.sopt.stackdump Program received signal SIGSEGV, Segmentation fault. 0x61016545 in stack_info::walk () from /usr/bin/cygwin1.dll (gdb) bt #0 0x61016545 in stack_info::walk () from /usr/bin/cygwin1.dll #1 0x7c859dcc in OutputDebugStringA () from /cygdrive/c/WINDOWS/system32/kernel32.dll #2 0x40010006 in ?? () #3 0x in ?? () (gdb) list 1 !-! I have to apologize for not being more precise, but I'm not even sure I understand the backtrace. This seems to be early during the program startup (i.e. before the main is reached) ? Could this be cygwin specific and/or does this ring a bell ?

any information that could be usefull or what I can do to solve this.
The single most valuable thing you could do would be try and extract a
simple testcase that demonstrates the problem. AFD is a huge project and
there may be many confounding factors; if you can write a little
self-contained program that opens and uses fifos in the same fashion as AFD
and shows the same effects, the problem would be a lot more tractable.
I have managed to write a little test program that shows that the fifos
do not work as I expected it. The attached program can be compiled simply
by 'cc fifot.c'. When called without any argument it opens the fifo fifot.fifo
and does a select on it to wait for some data to arrive. When called with
an argument it opens the fifo for writting and writes Hallo Ballo!.
Calling this program under cygwin as follows:
./a.exe 1
will cause it to block. Under linux it does not block and I would expect under
any other unix like system it will not block either (which I have not tested).
My understanding of fifos was that when I open a fifo for both reading and
writting, I could write to a fifo without it blocking.
Is cygwin handling fifos correct here and my understanding wrong?

Re: Send command and parameters into cygwin.bat
Now I can start an application in cygwin with a single command:-) @echo off C: chdir C:\program\cygwin\bin bash --login -i -c %xmds But how should I write if I want to start the application with a certain parameter or input file? What I would like to do is to run the following command xmds -i c:\path\ring.xmds. Best regards!

Re[2]: add folder name to filename
hi Nikolaos
NAP Fixed :
NAP added a space after folder:
NAP for file in folder */*; do
^^
NAP echo folder */*
NAP dir=$(basename $(dirname $file))
NAP base=$(basename $file)
NAP mv $file $(dirname $file)/${dir}_${base}
NAP done
Script started, file is typescript -- file - reserved word
hint: man file
