Recently I've been trying to learn the Raku language, and I tried to make a simple Snake Game.
The code starts with this :
use SDL2::Raw;
use Cairo;
But when I compile using rakudo raku.raku, I get this error :
Cannot locate native library 'SDL2.dll': error 0x7e
in method setup at C:\Program Files\Rakudo\share\perl6\core\sources\60460C9F1B4C4D337A9E1B809E754542AE8E6474 (NativeCall) line 319
in method setup at C:\Program Files\Rakudo\share\perl6\core\sources\60460C9F1B4C4D337A9E1B809E754542AE8E6474 (NativeCall) line 366

in block <unit> at raku.raku line 10
I succesfully installed SDL2::Raw and Cairo with zef install SDL2::Raw and zef install cairo and when I type zef list, it lists the modules as installed :
===> Found via Zef::Repository::LocalCache
Cairo:ver<0.3.2>
SDL2::Raw:ver<0.3>
Random information :
line 10 of raku.raku is SDL_Init(VIDEO); and line 319 of 60460C9F1B4C4D337A9E1B809E754542AE8E6474 is nqp::buildnativecall(self,
Thanks for any answer !
I would check the documentation for SDL2::Raw which gives instructions on making sure you have the SDL2 libraries installed.
As it looks like you're on windows you want https://libsdl.org/download-2.0.php

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.
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
CC: lua_lua
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).
I'm on OS X 10.11.1 running the latest version of X Code. I installed Lua 5.3 today from source with no problem. Seems to work correctly. No errors installing luarocks and then using it to install moonscript. However, both moon and moonc give the following error when invoked from the command line:
$ moon
/usr/local/bin/lua: /usr/local/share/lua/5.3/alt_getopt.lua:24: attempt to call a nil value (global 'module')
stack traceback:
/usr/local/share/lua/5.3/alt_getopt.lua:24: in main chunk
[C]: in function 'require'
/usr/local/lib/luarocks/rocks/moonscript/0.4.0-1/bin/moon:2: in main chunk
[C]: in ?
Looking at alt_getopt.lua shows that it is indeed using the now-defunct 'module' keyword. The GitHub project for this module appears to be dead with no action in the past 3 years.
How should I proceed to get Moonscript working on my system?
Yes, as you noted, module has been deprecated for quite a while and was only working with earlier versions because of compatibility switches.
You can comment out the line 24 in alt-getopt and add the following line to the end of the alt-getopt.lua file: return {get_opts = get_opts, get_ordered_opts = get_ordered_opts}.
This should make this module Lua 5.2/5.3 compatible (I haven't checked if there are any other compatibility issues with using Lua 5.3 though).

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.
