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
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
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.
Operating System: Windows 8.1
Cygwin Version: Latest version, as of Sept. 9, 2014.
Guile Version: 1.8
Background:
My overall goal is to install a program called "MIT Photonics Band (MPB)" on Windows 8.1 using Cygwin. I am a new user, as I started using Cygwin a few days ago. I was able to install all required packages successfully after some troubleshooting. Eventually, I installed the MPB program using the generic ./configure, make, make install commands with slight modifications. All of this appeared to be successful.
The Problem:
When I try to run the executable program, I get the following error:
ERROR: In procedure primitive-load-path:
ERROR: Unable to find file "ice-9/boot-9.scm" in load path
Attempt At Solution:
The following is a page of the MPB installation manual:
MPB Installation Manual - Shared Libraries.
It appears to address my issue. Note that it mentions LIBDIR and foobar. For my operating system, foobar is PATH. The LIBDIR, however, I do not know explicitly because my "make install" output did not indicate it, as the manual suggests it should have. Anyhow, I found the location of ice-9/boot-9.scm through a computer search and its directory happens to be here:
C:\cygwin64\usr\share\guile\1.8\ice-9
Hence, I ran the following command (again, for a Windows 8.1 operating system) in bash:
$ export PATH="/usr/share/guile/1.8/ice-9:$PATH"
However, note that when I run $PATH, I get this message:
-bash: /usr/share/guile/1.8/ice-9:/usr/local/bin:/usr/bin:/cygdrive/c/Program: No such file or directory
I also tried:
$ export GUILE_LOAD_PATH="/usr/share/guile/1.8/ice-9:$GUILE_LOAD_PATH"
That yielded:
-bash: /usr/share/guile/1.8/ice-9:: No such file or directory
Furthermore, I tried to copy and paste the "ice-9" folder in various locations for a quick and sloppy solution, but it was to no avail. I searched online for answers as some users have had an issue with the program not finding the ice-9/boot-9.scm file in the past. I could not get my problem solved.
Please let me know if I need to provide more information. I appreciate the help!
EDIT: In response to the first user's post, I used the command echo $PATH and the following was the output:
/usr/share/guile/1.8:/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/NVIDIA Corporation/PhysX/Common:/cygdrive/c/Program Files (x86)/AMD APP/bin/x86_64:/cygdrive/c/Program Files (x86)/AMD APP/bin/x86:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files (x86)/Windows Live/Shared:/cygdrive/c/Program Files (x86)/ATI Technologies/ATI.ACE/Core-Static:/cygdrive/c/Program Files/MATLAB/R2013a/runtime/win64:/cygdrive/c/Program Files/MATLAB/R2013a/bin:/cygdrive/c/Program Files (x86)/Windows Kits/8.1/Windows Performance Toolkit:/cygdrive/c/Program Files/Microsoft SQL Server/110/Tools/Binn:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/System32/Wbem:/cygdrive/c/WINDOWS/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files/MATLAB/MATLAB Compiler Runtime/v81/runtime/win64:/usr/lib/lapack
Note that the problem still persists.
EDIT 2:
So I opened the "load.scm" file for GUILE and I found this line:
(define load-path '("/usr/share/emacs/20.7/lisp/"
"/usr/share/emacs/20.7/lisp/emacs-lisp/"))
I tried to add /usr/share/guile/1.8/ to these directories, but that didn't do anything either. Can't tell what's wrong.
Im trying to compile a Qt project based on the example given here.
I managed to compile without errors, but during execution there are errors. I'm getting these errors in pop up windows:
-open /dev/dsp error
-init failed
-start capture failed
-get frame failed
Moreover, the output displays:
sh: line 0: .:setqt4env:file not found
Trying open file
Could not open File! Error code: 5
/home/QFaceRec/QTFaceRecForPC exited with code 0
SIGSEGV Error when debugging with Qt Creator.
I have googled, answers are due to the application tries to access memory illegally.
Therefore, I try to execute in su - / root, but the run time error remain unsolved.
Im trying to compile and run the code in fedora with qt creator without the GPIO and serial port setting.
Anyone got any ideas to my problem? or knows how to compile the qt code in the link above
Answers are due to the application tries to access memory illegally. Therefore, I try to execute in su - / root
Do not do that! The illegal memory access is not a matter of permissions, it's a matter of the software having bugs. By running it as root, there's a possibility that those bugs will wreck your system.
I recently reinstalled Cygwin on my computer in order to get access to several command line elements that I was missing. I have never had previous difficulty with Cygwin, but after this reinstallation, an error message continues to appear after (almost) each command entered. For instance:
-bash-4.1$ wc m1.txt
3 [main] bash 2216 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x38D000)
-bash: fork: retry: Resource temporarily unavailable
2013930 4027950 74968256 m1.txt
Generally, the command still runs (as seen above), but not always. Occasionally, the 'error' message occurs several times in a row (the initial number "3" will then change to a "4" or "2", notably if I start a second Cygwin window.
Also, as soon as I start up Cygwin, I get the following message before the prompt:
3 [main] bash 6140 child_info_fork::abort: data segment start: parent(0x26D000) != child(0x36D000)
-bash: fork: retry: Resource temporarily unavailable
-bash: fork: Resource temporarily unavailable
-bash-4.1$
At the moment, I am debating whether to uninstall/reinstall Cygwin again or just live with the error messages, but I was curious if there might be an issue that I am unaware of.
(assuming Cygwin is installed at C:\Cygwin):
Open Task Manager and close any processes that look to be Cygwin related.
Open C:\Cygwin\bin in Windows Explorer
Verify that dash.exe, ash.exe, rebase.exe, and rebaseall exist in this folder
If any of them are missing, re-run Cygwin setup and select the dash, ash, and rebase packages
right-click your C:\Cygwin folder, uncheck Read-only (if its checked), and press OK.
When an error about not being able to switch some files comes up, select "Ignore All". Wait for this process to complete.
Browse to C:\Cygwin\bin in Windows Explorer
Right click dash.exe and click "Run as Administrator". A command Prompt should appear with nothing but a $
Type /usr/bin/rebaseall -v, hit enter, and wait for the process to complete.
If you get errors about Cygwin processes running, try Step 1 again. If that still doesn't work, Restart your computer into safe mode and try these steps again.
A commenter noted that, depending on your settings, you may have to type cd /usr/bin && ./rebaseall -v instead.
Try opening Cygwin again.
This process worked for me. I hope it works for you guys too.

I would like to add the following to the above answers, as it is what I had to do after reinstalling Cygwin:
Navigate to the "/usr/bin" directory (usually, C:\cygwin\bin) and right click, Run as Administrator the file: dash.exe
Then, at the $ prompt type the following, hitting enter after each line:
cd /usr/bin/
/usr/bin/peflags * -d 1
/usr/bin/rebaseall -v
What it does is, it marks the dll's as "rebase-able," and then rebases them. You have to have peflags.exe in addition to the above files (in previous answers). You may have to restart windows after doing this and you will definitely need to make sure that there are no processes nor services belonging to cygwin running. (Use task manager, kill any related processes, and then under the services tab look for any service starting with CYG and stop it.)
After doing this, I was able to get cygwin to run without any errors about dll's being loaded to the wrong addresses aka fork errors, etc.
I hope that this helps others, as it was a pain to find.
SOURCE: http://www.cygwin.com/faq.html#faq.using.fixing-fork-failures
and the rebase README file.
To add on to other answers here, we ran into the same issue but could not run the rebase command from the ash or dash shell. However, when launching the command from the Windows cmd shell, the following worked.
cmd /c "C:\cygwin64\bin\ash.exe /usr/rebaseall -v"
-v is to get verbose output
I found another information here :
http://cygwin.com/ml/cygwin/2014-02/msg00531.html
You have to delete the database at
/etc/rebase.db* and do in a "ash" windows :
peflags * -d 1
rebaseall
It works for me on 2 servers.
I solved this problem by restarting my computer. Probably installed a driver update and kept using sleep instead of shutting down.
Experienced the same issue when loading Cygwin with cygiconv-2.dll forking and not loading successfully in the Cygwin terminal, but after turning off my AntiVirus (it was specifically Ad-aware), the issue resolved, and Cygwin worked properly.
In case you are using babun's Cygwin, after rebaseall, try launching Cygwin by executing .babun\cygwin\cygwin.bat in a Windows command prompt or Windows explorer.
This works for me (while launching babun's default console - mintty results in fork error).
I had the error on win10 and i was trying to rebase to c: before install.
then i saw that the installer was installing it instead to c:/Users/myuser
so i was coping all files from c:/Users/myuser to c:.badun
and then restart plus open badun.bat
not shure if this was wise its now duplicated XD... but then it worked again.
Rebaseing didn't help in my case. In addition to what other people suggested, I noticed that reducing the length of PATH environment variable fixed the issue for me (and for other people as well as can be seen from this answer).
This issue is intermittent in nature & I found this issue when there is network is too slow to connect to remote machine on AWS.... I have Shell script that runs through Gitbash shell & it connects to AWS EC2 instance with ssh..... Most of the time, it ran correctly but 2 out 100 times it get into this issue bash: fork: retry: Resource temporarily unavailable .... Killing the MSYS2 terminal from task manager helps to overcome with this issue....
Negative side is you need to run the scripts from the beginning...
I had the same issue on Windows 10 and the mobaxterm app (which uses cygwin) and I tried all of answers listed here however for me, the solution was to simply delete the "CryptoPro CSP" application.
I started facing this problem after upgrading to windows 10. As of now I do not see that any of the above method working.
What I am noticing is that if you start cygwin with admin right (right click and say "run as admin") then it works fine.
Or you open cmd as administrator and then launch cygwin from there, then also it runs fine.
Just reinstall cygwin and select TCL and activate EXPECT
when trying to install cygwin, I keep getting this error message:
the entry point
rl_filename_rewrite_hook could not be

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.
