CYGWIN + windos10 + eclipse clp prolog

[Manu goswami]

Hi Developers,

I have previously build eclipse clp prolog several times in CYGWIN but suddenly it has started to show ‘SEGMENTATION FAULT’ even after fully reinstalling CYGWIN and removing (manually deleting) old Cygwin.  No error is reported at build time and .exe is successfully generated but on execution of .exe file after build shows ‘ SEGMENTATION FAULT’. Kindly support in resolving most urgently.


Warm regards,

Manu

Report upstream to wherever you got the sources for whatever "eclipse 
clp prolog" is - in whatever language(s) they use - web links to 
projects and sources are more informative than garbled buzzwords.

SIGSEGV is a symptom of a programming error - out of bounds access - 
caused by following the wrong pointer to an invalid location, using a 
NULL pointer, array or buffer index incorrect, use after free, incorrect 
object size or indirection, just to suggest some of the most frequent 
and common causes.

If you have made your own local and/or recent changes to the sources, 
they are invariably the likely cause of the issue, so recheck any recent 
local work very carefully.

The Cygwin project provides packages for execution and development but, 
as Cygwin is an all volunteer effort, with limited personnel each with 
limited time, so all projects built using those packages are the 
responsibility of those projects downstream of Cygwin, otherwise we 
would not have any time to maintain and expand the packages supported.

Re: CYGWIN + windos10 + eclipse clp prolog

[Manu goswami]

Hi Brian,

Thanks for the reply.

Eclipse clp is a version of open source prolog and had been running successfully on my computer for some months.

There has been no change in source code.

What new I did was to install msys2 and call a particular Cygwin compiled exe from msys2. The called Cygwin compiled  .exe did run from msys2 but most probably crashed Cygwin causing segmentation fault ever since. Surprisingly the called Cygwin compiled .exe runs successfully but eclipse clp prolog .exe fails.

Should I remove msys2 ? as I have reinstalled Cygwin multiple times ever since this error occurs.


Warm regards,

Manu

That's the only recent local change, but the Msys2 DLLs are often 
outdated Cygwin derivatives, and Cygwin programs may try to call 
functions nonexistent in Msys2 DLLs.
The situation can be mitigated by setting the path to run the Cygwin 
compiled code using the Cygwin DLLs from the Cygwin bin, and changing 
the path to run the Msys2 tools using the DLLs from the Msys2 bin.

Re: CYGWIN + windos10 + eclipse clp prolog

[Manu goswami]

Hi Mr Brian,

Yes, you were right. The problem was upstream in Eclipse Prolog Source code. Has been resolved now. You may consider the issue closed.

Only one query. Cygwin is a good idea and works well.  But is it weaker in GUI and multithreaded as compared to msys2? Kindly advise

Warm regards,

Manu

As previously stated, Msys2 DLLs are often outdated Cygwin derivatives, 
focused on allowing development of Windows apps using GNU tools, so the 
Windows apps developed using those tools can make full use of Windows 
GUI and multithreaded facilities, but Cygwin is better than Msys2 in the 
respect of being more functional and up to date libraries and tools, as 
it provides a complete POSIX and Linux compatible layer over Windows, 
with over 10k packages including enough applications to support the 
common X clients, window managers, and desktop environments GNOME, KDE, 
LXDE, MATE, as well as command line and development tools and libraries 
for building POSIX sources into Cygwin apps, or native Windows apps 
requiring Mingw libraries and tools.
