building expect problems on W10

building expect problems on W10

[rih3306]

I'm having trouble building expect. 

I'm using W10 + cygwin + GCC 9.1.0

$ uname -a
CYGWIN_NT-10.0  GZ1CB  2.11.2(0.329/5/3) 2018-11-08 14:34 x86_64 Cygwin

using this configure line
./configure --build=x86_64-unknown-cygwin  
CC=/cygdrive/C/work/usr/local/bin/gcc  --cache-file=config.cache 
&>expect-configure-out.txt

Configure output includes
 
This script, last modified 2003-10-07, has failed to recognize
the operating system you are using. 

Where do I start, suggestions?

Thank you

That's an odd combination, an ancient version of Cygwin with a new gcc
(which you probably built).

Why are you configuring like a cross-compilation?

None of that should be needed to build a package that is to be used in
the current version.

Configure usually shows "Target: x86_64-pc-cygwin", but yes the log also
shows "host='x86_64-unknown-cygwin'".  Anyway that is using configure
without any build, or host parameter.

Install cygport, the current Cygwin expect src package, upgrade Cygwin and all
packages that don't conflict with your local builds.

Untar the src package, and use cygport to build expect under Cygwin, as it takes
care of dependencies and quirks, from the directory containing the cygport file:

	$ cygport expect.cygport download all

which should build without errors.

Then you can update the expect version in expect.cygport and retry with the
latest source version.

Re: building expect problems on W10

Good suggestion thank you.

Can we please consider where I'm at presently before trying that?

I'm now able to build expect.exe and libexpect5.45.4.dll using this
configure line


./configure --disable-option-checking '--prefix=/usr/local' 
'--build=x86_64-unknown-cygwin' 'CC=/cygdrive/C/work/usr/local/bin/gcc'
'CFLAGS=-mcmodel=large' 'build_alias=x86_64-unknown-cygwin'
--cache-file=../config.cache --srcdir=. &>configure-out.txt


followed of course by make.

However,  running ./expect.exe produces a stackdump

which is here.

  Exception: STATUS_ACCESS_VIOLATION at rip=00000000000
rax=0000000000000000 rbx=0000000000800080 rcx=0000000000000000

Stack trace:

I get the stackdump both with and without the memory model option in the
configure line.

Is it possible to tweak my configure line and get rid of the stackdump?

Thank you.
