First post in the list, I hope I am not mistaken in the place to post
the question, but let's give it a try.
I'm having hard times with cygwin here, random libraries stop working
once I update or install new ones.
Today I run 'rebaseall' and it detected a lot of completely missing DLLs
from packages. So I wrote a script to build up the list of packages that
contained the DLLs to use setup-x86_64 to reinstall them.
After reinstalling, 'rebaseall' ran without apparent issues. But still
ssh and perl are unusable.
If I run the ssh client, it simply returns to the command prompt. Perl
likewise. Passing any commandline parameters does not change it.
If I run ssh with 'strace' ('strace ssh'), it pops up a windows dialog
'the procedure entry point __memcpy_chk could not be located in the
dynamic link library c:\cygwin\bin\cygcrypto-1.0.0.dll'
I found this file is located in the 'openssl100-1.0.2o-1' package. The
file is present and has about 2.3MB in size. I've deleted the package's
tar from within my local cygwin packages cache and reinstalled. Still
With perl I get the same, but the complained file is called
Maybe I should be looking for that __memcpy_chk from another DLL; it may
be missing and strace/cygwin informs a misleading DLL name?
I'm using Windows 10 1709 / 16299.248.
cygwin's dll is: cygwin1.dll file version: 2008.0.0.0, version: 2.8.0.
Thanks in advance to whoever has suggestions on how to tackle with this
issue, it's been plaguing me for months now.
