Cygwin error: “-bash: fork: retry: Resource temporarily unavailable”

Question

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, bu

Answer 1

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.
