Whenever I try to run my .exe cobol file, i get this error..
fileName.exe Entry Point Not Found
The procedure entry point_impure_ptr could not be located in the dynamic link library cygwin1.dll
I am using OpenCObol and cygwin ver1.7.15.thanks
You'll need to specify the proper path for the command below, but Cygwin seems pretty persnickety with entry point addresses and updates, The system includes a rebaseall command to help fix this problem. Most times I've witnessed it is after a setup.exe pass, while the Cygwin system was still active (and perhaps only in the background and not visible).
C:\Users\btiffin\cygwin\bin\dash -c '/usr/bin/rebaseall'
Run that from a Windows CMD shell (while Cygwin isn't active, say after a clean boot and before running the Cygwin shell. Basically cygwin1.dll can't be open). You'll need to use the proper Windows path to dash for your particular install. Google Cygwin rebase for detailed articles.
I had a similar error message after upgrading from cygwin version 1.5 to 1.7. I solved it by completely removing and reinstalling 1.7 from scratch. I was told there might have been a problem with multiple versions of dlls.

I have nuXmv installed and added to my path on windows but have not seen instructions anywhere for adding it to the options->solvers menu on windows.
On Linux, as soon, as I've added nuXmv's bin folder to my path and restarted Alloy, it appeared in the list of available solvers. Make sure that you can run it in command line as nuXmv
I'm trying to execute a .sh script (that wasn't written by me) and I get the following error:
0 [main] echo (5320) C:\Program Files\Git\usr\bin\echo.exe: *** fatal error - cygheap base mismatch detected - 0x180343408/0x180317408.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version. The most recent version should
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution. Rebooting is also suggested if you
are unable to find another cygwin DLL.
I tried to follow the instructions in the error but I only have one cygwin1.dll file.
So I tried to execute the following command in a git bash shell:
/c/cygwin/bin/man
and I get:
0 [main] man (11952) C:\cygwin\bin\man.exe: *** fatal error - cygheap
base mismatch detected - 0x180317408/0x180343408. This problem is
probably due to using incompatible versions of the cygwin DLL. Search
for cygwin1.dll using the Windows Start->Find/Search facility and

I already tried to disable ASRL options in the exploit protection panel (as suggested by somebody) and reboot but that didn't fix the problem.
If I write
which -a cygwin1.dll
I get:
/c/cygwin/bin/cygwin1.dll
/c/cygwin/bin/cygwin1.dll
It looks like I have two cygwin1.dll but actually I only have one..
I have been searching for a possible solution since days but nothing seems to work for me.
Any suggestion?
While the error message is mentioning cygwin1.dll, it is misleading as the Git for Windows is using MSYS and the file was renamed msys-2.0.dll
Unfortunately the MSYS team forgot to change the error messages when they imported and modified the Cygwin source:
I encountered the same problem while trying to build a certain C/C++ project from source in the Git Bash Terminal.
Based on the previous answers by #Harry and #matzeri it seems that Git Bash is what is causing this problem. To resolve it I had to disable ASLR for all executables in my Cygwin install folder (Usuall C:\cygwin64) using the command
Get-Item -Path "C:\cygwin64\bin\*.exe" | %{ Set-ProcessMitigation -Name $_.Name -Disable ForceRelocateImages }
I restarted the computer and then switched to using Cygwin Terminal and compiled from there.
NB: Cygwin Terminal comes by default with Cygwin installation
Find all the msys-2.0.dll's on your machine and add the suffix .bkp to them.
Wherever you found them at, copy "C:\Program Files\Git\usr\bin\msys-2.0.dll" to those locations.
Notes:
If you were to copy from C:\msys64\usr\bin\msys-2.0.dll to all other locations, then you lose that nice additional text at the end that shows the branch you're on (master)
Same goes if you just decide to delete all the extra dlls and just add C:\msys64\usr\bin to your path, there must be a dependencies it looks for relative to the directory it normally resides.
Because apparently I skimmed the selected answer and missed the part about msys-2.0.dll, I had to figure this out myself. For future reference:
Run listdlls -r -v -d msys-2.0.dll
Check Base, Path, and Version info for discrepancies.
I have instaled Cygwin after running MinGW for a while now. But when I try to compile the console gives me:
/usr/lib/gcc/x86_64-pc-cygwin/4.9.2/cc1.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
What does this mean?
I have the same problem and I found the solution.
According to the FAQ of Cygwin
Q: Why is C:\cygwin\usr\bin invisible from windows?
A: Because it does not really exist. In cygwin, /usr/bin is just a link to /bin.
So trying to add "C:\cygwin\usr\bin" to PATH will be in vain.
Add "C:\cygwin64\bin" to PATH instead. Hope this helps :)
You are missing a library, please run cygcheck /usr/lib/gcc/x86_64-pc-cygwin/4.9.2/cc1.exe or ldd /usr/lib/gcc/x86_64-pc-cygwin/4.9.2/cc1.exe to see what is the missing library.
(I'd rather ask a question in the comments first, but I don't have enough reputation yet.)
Your cc1 is unable to load some DLLs it needs to start. Looking at the Cygwin source code, this can be either a library specified in LD_PRELOAD, or -- more probably -- a library the executable depends on. The ? in the error message seems to be the default return value of find_first_notloaded_dll (hookapi.cc), in case the function can't determine what library is missing.
To diagnose the issue, I suggest checking your PATH variable (or even clearing it of any non-Cygwin paths and trying the compilation again) and/or using Dependency Walker to find the missing DLLs (start it from a Cygwin shell, so it can see the same PATH). ldd (included with Cygwin) may also give some clues, but I wouldn't bet on it.
It's possible a clean re-install of Cygwin will be necessary to solve the issue.
Most likely, you are simply missing /usr/bin in the PATH variable.
Adding 'export PATH=/usr/bin:$PATH' to your .bashrc file will solve the issue.
Adding some background info. I had the same problem when building my own program and linking it against graphviz cgraph.dll. Turns out this is related to where windows searches for DLLs (see here: https://msdn.microsoft.com/en-us/library/7d83bc18.aspx) So adding the path of your missing library to PATH should fix the problem.
It is unfortunate that the message doesn't include the name of the library. Luckily cmd.exe DOES give you this name (so it's good for something after all;)
Are you including the path to your lib directory?
Looks like you are not
I'm not very familiar with Cygwin, I mainly use MinGW, but I think the error message speaks for itself
I also came this error on windows machine while executing .exe file generated by scilab2C i.e toolbox for Scilab
For Windows 32 bit Add the environment variable path as follow :
C:\cygwin\usr\i686-pc-cygwin\bin
Hope so this will solve your issue.
Just had this problem trying to compile a package with make and it wanted some cygguile dll file that was just installed along with make.
My solution was I had not only migrated my cygwin64 directory across drives because the sector sizes were mismatched for some reason even though the drivers were both under 2TB and should have been using 512 byte sector sizes.. So I had to install a new system and move files over there, might have had weird permissions on them.
Also had to patch cygwin1.dll end of Jan 2020 because of a recent input problem in ConEmu with Windows 10 1903 build, but just did it again with this working so that doesn't seem to be the issue.
Reinstalling cygwin by deleting that entire directory, taking ownership of it first.., seemed to work now...
when trying to install cygwin, I keep getting this error message:
the entry point
rl_filename_rewrite_hook could not be
located in the dynamic link library
cygreadline7.dll
Has anyone seen this before ?
Thanks
I had the same error with cygwin1.dll. I checked in c:\cygwin\bin and noticed there were two files, cygwin1.dll and cygwin1.dll.new (possibly from a failed or aborted setup run?). The ".new" version was in fact newer (and slightly larger) than the existing cygwin1.dll, so I replaced cygwin1.dll with cygwin1.dll.new, and ran setup again. It completed with no errors.
First idea is to try reinstalling libreadline7 (or similarly named package) using the cygwin installer. Use the search field to enter readline to make it easier to find the right package.
Another option is that in the cygwin installer, change form Curr to Prev in order to switch to the previous-stable release. This means lots and lots of downloading and reinstalling. I anctually did manage to provoke my error into becoming a libreadline7 error, and switching to Prev at least got rid of the error messages. (Yay! Now bash, ssh server and git is working again! Back to work here then...)
Please check your path in WINDOWS (advanced system properties) environment. I found that C:\WinAVR\bin was coming before my cygwin path, so I moved that to the end, fixed my issue.
If you have multiple CYGWIN1.DLL files in your system, it definitely causes headaches if you're not careful.
All of the sudden svn stopped working in cygwin installation on windows xp. when I execute svn binary, nothing happens, svn process does not even show up in the Task Manager. I've reinstalled svn but it did not help (the last resort would be to uninstall cygwin itself). Everything else in cygwin works fine: awk,python,sed,more,less,tail and etc.
here is what is happening ...
mt#s022 ~
$ which svn
/usr/bin/svn
mt#s022 ~
$ svn --version
mt#s022 ~
$ svn status
mt#s022 ~
$ svn info
mt#s022 ~
$
Same problem as well.
No solution, but here's an interesting thing: For me, "curl" and "wget" are also broken in exactly the same way. This makes me wonder if it is one of the underlying networking libraries (libcurl, or similar) that is at the root of the problem (total guess).
EDIT: I have solved this problem. The problem turned out to be what seems to have been a "bad" version of openssl. I used the Cygwin setup program to "Reinstall" OpenSSL. The version number in setup is now "0.9.8n" which seems to have replaced "0.9.8", which I suspect was a bad version that was temporarily distributed, so if you were unlucky enough to update at the wrong time then this is what you got. The new version doesn't seem to be installed automatically just by updating normally. I'm guessing 0.9.8 is seen as the same version as 0.9.8n.
In case this doesn't solve it for others: the key insight was gained by launching svn.exe from Windows Explorer. While it exits silently when run from the bash command line, when run from Windows Explorer it pops up a window complaining: "the procedure entry point pqueue_size could not be located in the dynamic link library cygcrypto-0.9.8.dll". This allowed me to identify OpenSSL as the culprit. The same might be possible for other problems that manifest as commands silently exiting when run from the bash terminal.
This is what I did:
net stop sshd (this is optional)
remove /usr/bin/cygwin1.dll
remove /usr/bin/cygcrypto-0.9.8.dll
run cygwin-setup
reinstall cygwin-base
Hope this helps.
Ran into this problem. It seemed to have started when I added one small package and left everything else as keep. Solution that worked: remove cygwin1.dll, run cygwin's setup.exe, keep everything except base->cygwin. Updating that updated cygwin1.dll, and all was fine again.
I had same issue.
I followed the suggestion above and tried to launch svn from the windows explorer and it turned out that I had a problem with cygwin1.dll itself.
Doing a reinstall of the cygwin package solved my problem
I had the same problem and upgrading/reinstalling the cygwin base classes didn't help me neither...
Until I disabled the "CYGWIN sshd" service.
Therefore, if you run the Cygwin sshd process, stop it first, before upgrading Cygwin.
Good luck!
