Fwd: autoconf: ./configure fails on cygwin for crosstool-ng-1.24.0

Resend because of spam filter. This message has also been sent to
bug-autoconf@gnu.org.

Hello,


I tried to run ./configure on the package crosstool-ng-1.24.0 under cygwin64
and it fails.

Here is the output:
   ./configure: This script requires a shell more modern than all
   ./configure: the shells that I found on your system.
   ./configure: Please tell bug-autoconf@gnu.org and
   ./configure: crossgcc@sourceware.org about your system, including
   ./configure: any error possibly output before this message. Then
   ./configure: install a modern shell, or manually run the script
   ./configure: under such a shell if you do have one.

The shell is bash:
   $ echo $SHELL
   /bin/bash

Bash version:
   $ $SHELL --version
   GNU bash, Version 4.4.12(3)-release (x86_64-unknown-cygwin)
   Copyright (C) 2016 Free Software Foundation, Inc.

Is there anything I can do to solve the problem?
If I have to provide more information I'll gladly do.

Thank you in advance.

Best regards,
Philipp

Hi Allan,

thank you for your suggestion.
Unfortunately, this leads to the same result and error message.

Based on your suggestion, I installed other shells:
zsh 5.5.1-1
   $ /bin/zsh ./configure
   ./configure: This script requires a shell more modern than all
   ./configure: the shells that I found on your system.
   ./configure: In particular, zsh 5.5.1 has bugs and should
   ./configure: be upgraded to zsh 4.3.4 or later.

zsh 5.1.1-1
   $ /bin/zsh ./configure
   ./configure: This script requires a shell more modern than all
   ./configure: the shells that I found on your system.
   ./configure: In particular, zsh 5.1.1 has bugs and should
   ./configure: be upgraded to zsh 4.3.4 or later.

dash 0.5.9.1-1
   $ /bin/dash ./configure
   ./configure: This script requires a shell more modern than all
   ./configure: the shells that I found on your system.
   ./configure: Please tell bug-autoconf@gnu.org and
   ./configure: crossgcc@sourceware.org about your system, including
   ./configure: any error possibly output before this message. Then
   ./configure: install a modern shell, or manually run the script
   ./configure: under such a shell if you do have one.

I don't want to build zsh 4.3.4. from source unless I have really no
other option.
I'm not convinced this would work though as it fails with a newer version.
What shell would be suited best for autoconf?

Best regards,
Philipp

It should work with your Bash. The fact that it fails with both your
Bash, and with recent zsh, suggest a configuration problem of some sort
(not a problem with your shells per se). You can try debugging it by
using 'bash -x configure', or by putting 'set -x' into 'configure' just
before the place you think is causing the problem.

Hello Paul,
hello Allan,

thanks to your input I was sure that the problem had to be found in my 
specific configuration and so I looked around and found it:
I had installed cygwin into the windows program folder and symlinked the 
folder to C:\cygwin64. This seems to have caused problems, because 
deleting the symlink and moving the folder to C:\cygwin64 directly 
resolved the issue. Now ./configure runs until it fails to find libtool, 
which I consider a success.

I can provide the /bin/bash -x ./configure log file upon request.

Thank you!

Philipp
