cygwin: diff.exe: error while loading shared libraries: cygsigsegv-2.dll - dll

I installed the latest cygwin x86-64. I added diffutils to get the basic diff(1) linux command. When I now run it, I get:
diff.exe: error while loading shared libraries: cygsigsegv-2.dll
I did a search for the dll here, but there are zero matches, not found.
I then re-ran the installer and did a search in the installer search box on this dll, and nothing came up.
Can you please advise?

cygsigsegv-2.dll is part of package libsigsegv2, which is required by
diffutils:
# diffutils
sdesc: "A GNU collection of diff utilities"
category: Utils
requires: cygwin libiconv2 libintl8 libsigsegv2
Installing that package should fix the problem.

Library not loaded: #rpath/libtbb.dylib in Prophet / Python

I'm on a Mac X1, Monterey.
I've installed prophet and run into this issue when trying to fit a model.
RuntimeError: Error during optimization: console log output:
dyld[90668]: Library not loaded: #rpath/libtbb.dylib
Referenced from: /Users/{username}/opt/anaconda3/lib/python3.9/site-packages/prophet/stan_model/prophet_model.bin
Reason: tried: '/private/var/folders/cd/dfrqgp4s4ll55cwb7rtgccbw0000gq/T/pip-install-rjpuj450/prophet_d7e4cce10e414c89a572fe3605ae9269/build/lib.macosx-11.1-arm64-cpython-39/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/libtbb.dylib' (no such file), '/private/var/folders/cd/dfrqgp4s4ll55cwb7rtgccbw0000gq/T/pip-install-rjpuj450/prophet_d7e4cce10e414c89a572fe3605ae9269/build/lib.macosx-11.1-arm64-cpython-39/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/libtbb.dylib' (no such file), '/usr/local/lib/libtbb.dylib' (no such file), '/usr/lib/libtbb.dylib' (no such file)
I know this has to do with the wrong paths being searched. I can find the dylib in
/Users/{user}/opt/anaconda3/lib/python3.9/site-packages/prophet/stan_model/cmdstan-2.26.1/stan/lib/stan_math/lib/tbb/
But, it seems prophet doesn't know to look there. I'm curious how I can update/fix either the rpath variable or find another solution?
I tried to create a symbolic link with sudo ln -s, but don't have permissions on the laptop.
TIA!
I got it to work on Apple Silicon (M1 Max in my case) by installing older versions of both pystan and prophet:
pip install pystan==2.19.1.1
pip install prophet==1.0
The other important piece of the puzzle is that you should use Python 3.8 to get it working.
Installing older versions of the libraries and using Python 3.8 are both talked about in issue #2002 on Github, but there's not really an explanation of the libtbb.dylib error message.

Installing kdesu on NixOS

When setting advanced properties on a program/link to start as another user it is throwing the error:
Sorry - Plasma
KDEInit could not launch 'kdesu':
Could not open library 'libkdeinit5_kdesu'.
Cannot load library /run/current-system/sw/lib/libkdeinit5_kdesu: (/run/current-system/sw/lib/libkdeinit5_kdesu.so: cannot open shared object file: No such file or directory)
I tried to install kdesu using:
[root#nixos:~]# nix-env -qaP kdesu
nixos.kdeFrameworks.kdesu kdesu-5.36.0
[root#nixos:~]# nix-env -iA nixos.kdeFrameworks.kdesu

which: no kdesu in (/root/bin:/run/wrappers/bin:/etc/per-user-pkgs/root/bin:/root/.nix-profile/bin:/nix/var/nix/profiles/default/bin:/run/current-system/sw/bin)
I also tried installing nix-env -iA nixos.kde-cli-tools but that does not work either.
Any suggestions on how to get kdesu installed on NixOS?
As a general rule, unlike many distros on NixOS installing a library directly doesn't work as intended; the application that needs the library won't be able to find it. Instead, the package must declare all it's dependencies.
Packages which have optional dependencies tend to have a way to add them via configuration. You may want to try something like this in /etc/nixos/configuration.nix
services.xserver.desktopManager.plasma5.extraPackages = with kdeFrameworks;
[ kdesu
];
I'm glad to see that you filed an issue on Nixpkgs, because this is not a configuration issue but a packaging bug.
It looks like kdesu lives in some libexec dir that doesn't hasn't been added to your PATH. It belongs to the kde-cli-tools package. You can run it with
$(nix-build '<nixpkgs>' -A kde-cli-tools --no-out-link)/lib/libexec/kf5/kdesu
You can use the above as an alias to launch kdesu until the fix to the packaging bug arrives.

When importing Nim module for Lua bindings, error shows: "could not load: lua(|5.1|5.0).dll"

I'm new to the Nim programming language, and coming from a Lua background, it excited me to find out that there is a module for adding Lua bindings to Nim.
I installed Nimble (Nim's package manager) for Windows and executed "nimble install lua" to download and install the correct module. Upon trying to import it and compile the source, this happened:
C:\Users\Ashley\Desktop\Stuff\Coding\Nim\Projects\LuaTest>nim c -r "C:\Users\Ashley\Desktop\Stuff\Coding\Nim\Projects\LuaTest\main.nim"
Hint: system [Processing]
Hint: main [Processing]
Hint: lua [Processing]
CC: main

Hint: [Link]
Hint: operation successful (10698 lines compiled; 1.262 sec total; 16.163MB; Debug Build) [SuccessX]
could not load: lua(|5.1|5.0).dll
Error: execution of an external program failed: 'c:\users\ashley\desktop\stuff\coding\nim\projects\luatest\main.exe '
I have Lua 5.1 already installed with the proper entries in PATH. It's located in Program Files (x86). The directory contains a dll called lua5.1.dll. I tried looking up the error on Google, but there were no results that helped. What could be the problem?
On Windows you can put the library at the same place as the generated binary. In this case the file should be called lua.dll, lua5.1.dll or lua5.0.dll. Also make sure that the library and binary are both for the same system architecture, either x86 (32bit) or x86-64 (64bit).

Not getting TBB to compile test examples

I am not getting TBB to work. I am following the steps in the "Getting started" document.
I am doing the following steps:
downloading the linux files + the sources files.
extracting them in 1 directory
calling make
going to tbb.../bin calling source tbbvars.sh intel64
going to examples/Getting_started/sub_string_finder
calling make
I then get the error:
sub_string_finder.cpp:32:30: fatal error: tbb/parallel_for.h: No such file or directory
I really googled a lot but can't find any related stuff.
I did also try to add some -I statement but it didnt help
I assume it is kind of a including/linking problem but I dont know how to fix.
This is all done on fedora 16 64bit. (kernel 3.1.4) // TBB version 4.0
The solution was to install tbb-devel package.

dlopen() error image not found

I have software that first loads a .dylib lets call libFirst.dylib using the following command:
void* handle = dlopen(path.c_str(), RTLD_LAZY | RTLD_GLOBAL);
Later on inside a function from the loaded libFirst.dylib I attempt to load another .dylib using the same command but for libSecond.dylib, the loading of this shared library gives me the following warnings in my Xcode console:
error warning: Ignored unknown object module at 0x129310 with type 0x8a8399
dlerror: dlopen(/path/libSecond.dylib, 9): Library not loaded: libFirst.dylib
Referenced from: /path/libSecond.dylib
Reason: image not found
What I don't get is that its says libFirst.dylib is not loaded but I am currently inside a function from libFirst.dylib, so how can this be?
All my paths in DYLD_LIBRARY_PATH appear correct too.
Thanks in advance, I have been stuck on this for days.
I ended up using -install_name to change the install name of all my libraries to #rpath/dylibName.dylib and then in Xcode I set the Runpath Search paths using #loader_path to find all my .dylibs that I was using.
use:
install_name_tool -id #executable_path/../Frameworks/mylib.dylib mylib.dylib
then check it with:
otool -D mylib.dylib
I think an easier way to get around this error would be to revert to an earlier version where you were not getting this error. Right click on the project folder and navigate to local history to revert to an earlier version. I verified this to be working on the android studio installed on Mac OS Big sur.
