Cygwin error: "child_info_fork::abort: Loaded to different address:"

Question

I am trying to build my software using cygwin-x86(32 bit version) on Windows-7.
Cygwin-x64(64 bit) works perfectly fine on the same machine. I want to build 32-bit executable.
Whenever I try cygwin-x86, I get the following errors:

[main] make 7780 child_info_fork::abort: C:\cygwin\bin\cygiconv-2.dll: Loaded to different address: parent(0x440000) != child(0x5F0000)
make: fork: Resource temporarily unavailable

I have checked this thread Cygwin Error

I have already tried everything mentioned in there, but I still continue to face the same issue.
Whenever i try /usr/bin/rebaseall -v or cd /usr/bin && ./rebaseall -v as mentioned in the step 7 of the accepted answer in the above mentioned thread, I get this error:

/usr/x86_64-pc-cygwin/sys-root/usr/bin/cygvtv_stubs-0.dll: skipped because wrong machine type. /usr/x86_64-pc-cygwin/sys-root/usr/bin/cygz.dll: skipped because wrong machine type.
Segmentation fault (core dumped)

I get this wrong machine type error for a lot of other .dll's as well.
As mentioned earlier I have cygwin-64 installed on my machine & working as expected. But while running rebaseall it is somehow looking for x86-64-pc-cygwin instead of 32 bit version.

Answer 1

The thread is obsolete.

run /usr/bin/rebase-trigger, close all cygwin processes and run again setup-x86.exe. Also without installing anything will execute a rebase for you.

You can also specify the option full.

Additional note: The most likely cause of fork problems on 32 bit system are too many programs and libraries installed.

for example: /usr/x86_64-pc-cygwin/sys-root/usr/bin/cygz.dll

belongs to cygwin64-zlib a cross library for building cygwin64 programs from cygwin32. Do you really need it ? If not, as I suspect, remove all cywgin64 packages .

Answer 2

The problem can also be triggered by an anti-virus program. (I saw it happening with Avast.) You can test if this is the cause by disabling it.
