Using CompareTool on Mac - macos

Is there a way / what's the way to use CompareTool on a Mac?
(How) can Ghostscript and ImageMagick be configured to work in this environment?
Thanks for your help.

You can download the latest version of GhostScript from http://pages.uoregon.edu/koch/
Locate the "GhostScript xx.xx" link with the highest "xx.xx" version number - it's usually near the top of the page - and click on it. This will start the download of the GhostScript PKG (Package Installer). How the download actually happens is dependant on your browser and system set-up, and thus outside the scope of this article.
Once the PKG has downloaded, open the folder it was downloaded to (this is usually "Downloads" within your own Home folder).
Double click the PKG icon and follow the on-screen instructions. Accept the defaults if you don't know what to change.
Once the process has finished, GhostScript should be installed and ready for action.

I recommend MacPorts or Homebrew which custom builds GhostScript and ImageMagick in your environment. Download MacPorts or Homebrew and type:
sudo port install ghostscript ImageMagick
or
brew install ghostscript ImageMagick
The port or brew command downloads GhostScript and ImageMagick and many of their delegate libraries (e.g. JPEG, PNG, Freetype, etc.) and configures, builds, and installs GhostScript and ImageMagick automagically.
I tried this out for myself with Homebrew on a MacBook Air, the MacPorts part I got from googling.

Brew installs not appearing in /usr/local/bin

I've installed a package using brew to a new Mac, imagemagick, and carried over a number of utilities that look for convert, a part of imagemagick in /usr/local/bin. These utilities can't find convert, using which, it's in /opt/homebrew/bin/convert.
In addition, I'm trying to get vscode to work from a command line. It's set up but running code gives the error ./MacOS/Electron: No such file or directory. Electron has been installed using brew but can only be found, again, in /opt/homebrew/bin/convert.
Any thoughts?
Since Homebrew v3.0.0, the default prefix is different depending on the chip architecture. The defaults are the following:
/opt/homebrew on Apple silicon
/usr/local on Intel
The main reason for this change was for Rosetta 2 compatibility.
It appears that you're trying to transition from an Intel machine to an Apple Silicon one. The simplest way to do this might be to reinstall all the formulae again via brew bundle. This shouldn't take very long thanks to the use of pre-built binaries.
Alternatively, you can always manually add /opt/homebrew/bin to your PATH (/usr/local is already in path).

getting ghostscript in docker image for mac

Apologies if this is a trivial question, I am very new to docker.
I'm trying to install ghostscript in a python base running on a mac. I've looked online and seen people load gs on linux with apt-get and on windows loading an exe installer program. On mac Ghostscript is loaded using brew, but brew is not in my docker image.
What options do I have? Should I try to find and pull a layer ghostscript? Copy the lib files into my image in the dockerfile? Somehow get brew in my image and use that to load?
Thanks
KenS's answer works - building from source code gives what I need, and also works for other architectures (where things like the apt-get or .exe installer I found through searches are platform dependent). I learned something about using Docker from his answer.

Which one I should download? "Download the latest version of libclang"

I want to install YouCompleteMe, on Mac OSX, early 2015.
I have installed it under guidance of Mac OSX part. However, I got one warning:
NoExtraConfDetected: No .ycm_extra_conf.py file detected.
Then I read the full installation guide, and know that I should Download the latest version of libclang. However, there are so many source code on the official webpage of LLVM, and I don't know what to install (figure below).
So, could you please tell me, which one I should install?
Thanks!
If you go to http://llvm.org/releases/download.html#3.8.0 you can see Pre-Build binaries for MacOsX that's what you need to download and extract. Once you extract this. You will need to source it's location using the path variable.
Now, You can also install clang using brew from the terminal.
brew install --with-clang llvm

How to install Poppler on Windows?

The most recent version of ScraperWiki depends on Poppler (or so the GitHub says). Unfortunately, it only specifies how to get it on macOS and Linux, not Windows.
A quick googling turned up nothing too promising. Does anyone know how to get Poppler on Windows for ScraperWiki?
Other answers have linked to the correct download page for Windows users but do not specify how to install them for the uninitiated.
Go to this page and download the binary of your choice. In this example we will download and use poppler-0.68.0_x86.
Extract the archive file poppler-0.68.0_x86.7z into C:\Program Files. Thus, the directory structure should look something like this:
C:
└ Program Files
└ poppler-0.68.0_x86
└ bin
└ include
└ lib
└ share
Add C:\Program Files\poppler-0.68.0_x86\bin to your system PATH by doing the following: Click on the Windows start button, search for Edit the system environment variables, click on Environment Variables..., under System variables, look for and double-click on PATH, click on New, then add C:\Users\Program Files\poppler-0.68.0_x86\bin, click OK.
If you are using a terminal to execute poppler (e.g. running pdf2image in command line), you may need to reopen your terminal for poppler to work.
Done!
Poppler Windows binaries are available from ftp://ftp.gnome.org/Public/GNOME/binaries/win32/dependencies/ -- but note that those aren't quite up-to-date.
If you're looking for Python (2.7) bindings (as this question's tag suggests), I requested them in the past via this bug report. A couple of people apparently managed to produce something, but I haven't checked those out yet.
As for a more recent (python bindings unrelated) poppler Windows binaries Google result, see http://blog.alivate.com.au/poppler-windows/
Finally, there's the brand-new (and currently very frequently updated) PyGObject all-in-one installer (mainly aiming to provide PyGObject-instrospected Gtk+3 Python bindings etc. for Windows), so if that's what you're looking for, go to http://sourceforge.net/projects/pygobjectwin32/files/?source=navbar
Download Poppler Packaged for Windows
https://github.com/oschwartz10612/poppler-windows/releases
I threw together a quick repo with the latest Poppler prebuilt-binaries packaged with dependencies for Windows. Built with the help of conda-forge and poppler-feedstock. Includes the latest poppler-data.
With anaconda installed on windows one can simply execute:
conda install -c conda-forge poppler
UPDATE 2
See the answer by Owen Schwartz.
UPDATE 1
Rumpel Stielzchen's comment:
This site is no longer maintained. Poppler version 0.68 is very
outdated today. You find the latest version compiled also for Windows
here: https://anaconda.org/conda-forge/poppler/files Sadly there is no
32 bit version, only 64 bit
… but this package contains no dependencies:
It seems that the Anaconda people have a tool to download a package
and all dependencies. And there is a file in the TAR package:
index.json which lists the package on which it depends. I downloaded
the dependencies one by one, and yes: It WAS a pain.
Original answer
Latest Poppler Windows binaries can be found here:
http://blog.alivate.com.au/poppler-windows/
Chocolatey
Poppler is available as Chocolatey package:
choco install poppler
By default Poppler is installed in C:\ProgramData\chocolatey\lib\poppler and shims are automatically created for the following tools: pdfdetach, pdffonts, pdfimages, pdfinfo, pdfseparate, pdftocairo, pdftohtml, pdftoppm, pdftops, pdftotext, pdfunite.
To update Poppler, run:
cup poppler
Scoop
Install from the main bucket:
scoop install poppler
By default Poppler is installed in ~\scoop\apps\poppler and shims are automatically created for the following tools: pdfdetach, pdffonts, pdfimages, pdfinfo, pdfseparate, pdftocairo, pdftohtml, pdftoppm, pdftops, pdftotext, pdfunite.
To update Poppler, run:
scoop update poppler
TeX Live
As mentioned in another answer, MiKTeX currently ships with Poppler tools, and so does another LaTeX distribution, TeX Live.
From the guide:
Command-line tools.
A number of Windows ports of common Unix command-line programs are installed along with the usual TeX Live binaries. These include gzip, zip, unzip, and the utilities from the poppler suite (pdfinfo, pdffonts, …)
Poppler suite is located by default in C:\texlive\<year>\bin\win32 and, if you can compile your LaTeX documents, should work out of the box since this location is added to the PATH by the installer.
To Simply install Poppler on Windows run through the below mentioned steps without touching the environmental varible.
Download the Latest Poppler Binary from the URL: http://blog.alivate.com.au/poppler-windows/index.html
Unzip it and copy the poppler-0.68.0_x86 folder in some path for ex, C:/User/Poppler/poppler-0.68.0_x86/poppler-0.68.0/bin
Now go to your Python code where you want to call Poppler for image conversion and use the below mentioned code snippet:
from pdf2image import convert_from_path
pages = convert_from_path('MyPdf.pdf', 500, poppler_path = r'C:\User\Poppler\poppler-0.68.0_x86\poppler-0.68.0\bin')
for page in pages:
page.save('out.jpg', 'JPEG')
You should consider using Windows Subsystem for Linux (WSL).
Enable WSL on Windows 10 (it will not work on S edition)
Install Ubuntu (latest version) on WSL from the Windows Store
Open Ubuntu command-line
In the Ubuntu Command-line, run the following commands:
sudo apt-get update
sudo apt-get upgrade
sudo apt install poppler-utils
pdftocairo -v - to check the installed version
You can then run pdftocairo (for example) in two ways:
Within the Ubuntu command-line: pdftocairo ...
Directly from Windows command-line: wsl pdftocairo...
NOTE: There is a default version of poppler for each release of Ubuntu. You will need to look up the instructions (there should be plenty on the internet), for how to install the latest version of poppler-utils on Ubuntu. This might involve quite a few steps, which will compile from the source code. For example, something like this https://askubuntu.com/a/722955. And then you might get a lot of problems.
The latest version of Ubuntu 19.04, can install Poppler 74. But Ubuntu 18.04 seems to be the latest version you can install for WSL for now, and that installs Poppler 62.
It looks like a version that is build-able with visual studio can be found here https://bitbucket.org/merarischroeder/poppler-for-windows/overview
Up to date binaries for Windows x64, Mac OSX-64, Linux-64bit can be found here
https://anaconda.org/conda-forge/poppler/files
Poppler version 0.84 is available at the link as of this writing which is very current.
The accepted answer and the link given by Alexey are no longer pointing to current versions of poppler
Update :
As of March 8, 2021 the best answer is by Owen Schwarz above https://stackoverflow.com/a/62615998/590388
Another option is that if you have installed MikTeX then poppler is included by default and is probably already in your PATH. In my case the binaries were installed under: C:\Program Files\MiKTeX 2.9\miktex\bin\x64
MSYS2 has the latest version available for install.
If you don't want to install the whole enviroment (or you wanted some kind of portable version) you could also just download Poppler straight from the repository, but then you'd also have to manually handle dependencies. Namely: libwinpthread, nspr, gcc-libs, nss, curl, brotli, openssl, libidn2, libiconv, gettext, libunistring, nghttp2, libpsl, libjpeg-turbo, lcms2, openjpeg2, libpng, zlib, libtiff, xz and zstd.
Install the Microsoft Visual C++ Build Tools
Install poppler through the Conda prompt conda:
conda install -c conda-forge poppler
please note: if you don't have anaconda installed, it can be downloaded from here,
https://docs.anaconda.com/anaconda/install/windows/

Imagemagick installation no good on Lion

I have a fresh installation of Lion. I need to install ImageMagick (IM) to use the "identify" command line tool to search for corrupt images in folders that have thousands of time lapse images.
I have installed IM from the Mac OS X Binary Release, word for word based on these directions.
I have Xcode 4.2 installed from the Mac App Store.
X11 appears to be installed default with Lion. X11 about shows: XQuartz 2.6.3 (xorg-server 1.10.3).
The problem is that IM's installation appears successful but every time I use the "identify" command it returns "identify: command not found".
I have searched and searched (within stack overflow, google, etc.) and found MANY MANY articles on both subjects (IM and detecting corrupt images), but I've found nothing that helps me out.
I have also tried installing MacPorts and that didn't work either. And it freaked me out as one of it's dependencies was downloaded from Facebook.net (WHAT?!). I did a fresh install of Lion after that happened.
Thanks for your time.
Installing ImageMagick with Homebrew worked for me:
brew install imagemagick
