What helps your system even more is deinstalling McAfee as it seems to
take a really safe but really dumb approach which slows Cygwin and Windows
drastically, unless you add a LOT of exclusions.
Then you can enable Windows Defender, and download and install Microsoft
Security Essentials if you are still on Win 7/8: Win 10 Defender includes
MSE functions so it is not required there.

Do you have security software installed that might be interfering with Cygwin?

This is often an issue of your security software having opened the
conftest.exe for inspection and the configure script expects to delete
it but cannot because it is now opened by another process.  Exclude your
working directory from the scan to resolve it.

It seems to sporadically be unable to remove a file 'conftest.exe' which is 
compiled in the tests within configure.  This shows up during configure as:

rm: cannot remove 'conftest.exe': Device or resource busy

The configure will then fail completely when this causes a critical test to fail.  

I suspect that this might have something to do with slowness to release an in-use file (the conftest.exe) in the Win7 operating system.  I've searched the archives and don't see this exact issue showing up in previous posts.  Have others experienced this problem?  Is there a fix which will allow me to complete building these packages? 


I ran into a similar problem on linux - but was unable to
describe it to the point where others could reproduce it -- so I 
manually worked around it in each case where it happened, until some
SW-update to the autoconf-stuff made it go away.  It also happened in 
multiple packages, so wasn't specific to any one -- but it also 
happened on *linux*.


The problem is that somehow the information for "conftest.exe" will
be *in* the directory "conftest.exe" with some temporary name.  It's 
really a weird one -- but it happened with different files (where

the actual file was in a directory that had the name of the file, and
the actual file being in the directory with some name like "out".

It happened with multiple SW products that I would build, but not
most.  Have no idea what caused it but do know that updating the
autoconf-related SW eventually made it go away.  Sorry can't be
more precise, but when I tried reporting it as a bug, different
dev-teams gave up and suggested re-formatting and re-installing 
linux.  So helpful!  


Occasionally I run into weird problems -- because of how my system
is setup -- but are still caused by bugs in the underlying SW --
like making perl, completely failed for a few years on my system
because I had a RAID 50 where the "optimal write size" was 12*64KB
(3 RAID-5's that were 4*64KB/stripe).  The underlying Gnu DB library
failed (probably still does, as no one wanted to try to fix it, 
was designed around the assumption that the optimal-write-size
would always be a power-of-2 -- which it is not.  


I even told how to reproduce and test for it (using a VM), but
it got ignored... ;^/

Errors using configure when building packages

2016-10-14 Thread Sinkler, Wharton
I've got a new Cygwin installation on Win7, which has issues with configure, 
the first step of building packages from source (I've seen this with 
ImageMagick, libtiff and others so it's not specific to the package I'm 
installing).  

It seems to sporadically be unable to remove a file 'conftest.exe' which is 
compiled in the tests within configure.  This shows up during configure as:

rm: cannot remove 'conftest.exe': Device or resource busy

The configure will then fail completely when this causes a critical test to 
fail.  

I suspect that this might have something to do with slowness to release an 
in-use file (the conftest.exe) in the Win7 operating system.  I've searched the 
archives and don't see this exact issue showing up in previous posts.  Have
