Starting with this very trivial C program:
#include <stdio.h>

int main(void) {
printf("Zstandard v%d\n", ZSTD_versionNumber());
}
and compiling with
x86_64-w64-mingw32-gcc -o test.exe test.c -lzstd
when I then run ./test.exe, I get the Windows critical-error-handler
dialog stating "The code execution cannot proceed because
libzstd-1.dll was not found. Reinstalling the program may fix this
problem."
My question is not how to fix the problem (I'm well aware of that),
but rather why that message is being displayed at all, and is it a bug
in Cygwin somewhere? All I could find Googling was previous
suggestions that Cygwin routinely calls SetErrorMode with, amongst
other things, SEM_FAILCRITICALERRORS with the intention of suppressing
this dialog.
Is that correct, and if so is this just me? :o)
Windows 10 22H2, Cygwin 3.4.10, running all the commands from mintty.
I also get the same popup if I run C:\cygwin64\bin\sh -c
"/cygdrive/c/path/to/test" either from a Command Prompt or even from
"Start -> Run". Running this via "sh" called from a non-Cygwin process
(itself invoked from a Command Prompt) which has also called
SetErrorMode is how I hit this.
Better to let you know that there is a problem, and what the problem is, so you
can fix it!
I have spent hours trying to track down initialization failures, when daemons
just ignored that a library they needed was not found or loaded!
Install the following package:
$ cygcheck -f /usr/x86_64-w64-mingw32/sys-root/mingw/bin/libzstd-1.dll
mingw64-x86_64-zstd-1.5.5-1
