I am having trouble getting the configure script to recognise the pango libraries i have installed via Homebrew, which are dependancies for the training tools. So far, I've followed all steps detailed here:
https://github.com/tesseract-ocr/tesseract/issues/1453
and here:
https://github.com/tesseract-ocr/tesseract/wiki/Compiling#macos
and after running the configure script, I keep on getting these warnings in the output:
checking for pango >= 1.22.0... no
configure: WARNING: pango 1.22.0 or higher is required, but was not
found.
configure: WARNING: Training tools WILL NOT be built.
configure: WARNING: Try to install libpango1.0-dev package.
checking for cairo... no
configure: WARNING: Training tools WILL NOT be built because of
missing cairo library.
configure: WARNING: Try to install libcairo-dev?? package.
The libraries are located where they should be, at /usr/local/Cellar/pango/1.42.4_1
I've tried running the configure script as per the instructions above:
./configure CPPFLAGS=-I/usr/local/opt/icu4c/include LDFLAGS=-L/usr/local/opt/icu4c/lib
as well as trying to add the path to the linking flags:
./configure LDFLAGS="-L/usr/local/opt/icu4c/lib -L/usr/local/Cellar/pango/1.42.4_1/lib" CPPFLAGS="-I/usr/local/opt/icu4c/include"
and I still can't get the script to see the libraries.
Thanks in advance for any advice on how to solve this.
It looks like pango and/or cairo and maybe other libraries depend on libffi. libffi is called to be keg-only in Homebrew. Even if libffi is installed it is not linked via symbolic-links. When pkg-config tries to find a library, it also checks for its dependencies. Since libffi cannot be located pkg-config tells that cairo is not available. Therefore, one needs to call
brew link libffi --force
This should solve the problem without touching anything extra. At least it worked for my case.
This is a modified version of the answer provided by Boris [Boris: just say the word and I will delete this].
Tested on macOS 10.13.6 High Sierra.
None of the pre-existing answers worked for me - I had to explicitly add libpng to my brew requirements as given by Boris:
brew install cairo pango icu4c autoconf libffi libarchive libpng
export PKG_CONFIG_PATH=\
$(brew --prefix)/lib/pkgconfig:\
$(brew --prefix)/opt/libarchive/lib/pkgconfig:\
$(brew --prefix)/opt/icu4c/lib/pkgconfig:\
$(brew --prefix)/opt/libffi/lib/pkgconfig:\
$(brew --prefix)/opt/libpng/lib/pkgconfig
./configure
Note: If you already have some of the above you might rather want to run brew reinstall in place of brew install, at the risk of damaging other projects.
I didn't need to supply any flags to configure.
The aim is of course to get the training tools to compile so that combine_tessdata, wordlist2dawg, dawg2wordlist etc. are available (I haven't found macOS binaries for these anywhere).
The full instructions then become:
git clone git#github.com:tesseract-ocr/tesseract.git
git checkout tags/4.1.0
cd tesseract
./autogen.sh
brew install cairo pango icu4c autoconf libffi libarchive libpng
export PKG_CONFIG_PATH=\
$(brew --prefix)/lib/pkgconfig:\
$(brew --prefix)/opt/libarchive/lib/pkgconfig:\
$(brew --prefix)/opt/icu4c/lib/pkgconfig:\
$(brew --prefix)/opt/libffi/lib/pkgconfig:\
$(brew --prefix)/opt/libpng/lib/pkgconfig
./configure
make -j
sudo make install
# -> You should now have access to tesseract
make training
sudo make training-install
# -> You should now have access to the training tools: combine_tessdata, wordlist2dawg, dawg2wordlist, etc.
# If not, check /usr/local/bin/ is on your PATH, i.e.
export PATH=/usr/local/bin/:$PATH
Footnote: How I diagnosed the libpng problem:
As stated above and here, the error thrown is not very helpful:
make training
Need to reconfigure project, so there are no errors
Digging a little deeper, configure throws some warnings along the lines of:
configure: WARNING: pango 1.22.0 or higher is required, but was not found.
configure: WARNING: Training tools WILL NOT be built.
configure: WARNING: Try to install libpango1.0-dev package.
checking for cairo... no
configure: WARNING: Training tools WILL NOT be built because of missing cairo library.
configure: WARNING: Try to install libcairo-dev?? package.
checking that generated files are newer than configure... done
I also had one for cairo
So you have to run configure in debug mode:
./configure --enable-debug
And check config.log by greping for pango (say):
$PKG_CONFIG --exists --print-errors "pango >= 1.22.0"
That is the line that throws the warning when configure is executed.
You can now execute that last line manually:
pkg-config --exists --print-errors pango
dyld: Symbol not found: __cg_png_create_info_struct
Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /usr/local/lib/libPng.dylib
in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Abort trap: 6
which is how I traced the libpng cause. (In my case I had to reinstall/relink libpng because of various long-running clashes associated with gnuplot/octave/aquaterm etc. etc.).
HTH someone
This is the most elegant solution to the problem I found:
brew install cairo pango icu4c autoconf libffi libarchive libpng
export PKG_CONFIG_PATH=\
$(brew --prefix)/lib/pkgconfig:\
$(brew --prefix)/opt/libarchive/lib/pkgconfig:\
$(brew --prefix)/opt/icu4c/lib/pkgconfig:\
$(brew --prefix)/opt/libffi/lib/pkgconfig:\
$(brew --prefix)/opt/libpng/lib/pkgconfig
./configure
https://github.com/tesseract-ocr/tesseract/wiki/TrainingTesseract-4.00#on-macos-mojave-with-homebrew
I fixed this by copying the pkgconfig files under libffi and icu4c
(find the path by typing brew link libffi icu4c in your terminal)
and pasting them at /usr/local/lib/pkgconfig and then set
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
While I'm trying to install rmagic, it shows following error

I'm using MacOS sierra, ruby version 2.2.3
I had this issue a while back. You need to install imagemagick. Per the github repo for the rmagic gem
Pre-reqs:
ImageMagick Version 6.4.9 or later. You can get ImageMagick from www.imagemagick.org.
I believe you can also install it with brew
$ brew install imagemagick#6
$ brew link imagemagick#6 --force
$ gem install rmagick
brew unlink pkgconfig
bundle install
brew link pkgconfig
did the trick for me
Updating RMagick and Imagemagick is a painful expierence. I have updated the Imagemagick version on my mac (MacOS El Capitan Version 10.11.5) with homebrew for one project in Ruby 2.3 to 6.9.5-9
$ convert --version
Version: ImageMagick 6.9.5-9 Q16 x86_64 2016-09-09
Now an older project in Ruby 1.8.7 refuses to work with the error message "this installation of RMagick was configured with ImageMagick 6.8.9 but ImageMagick 6.9.5-9 is in use". Thus I uninstalled "rmagick", but it can not be installed again
$ gem install rmagick -v 2.16.0
Building native extensions. This could take a while...
ERROR: Error installing rmagick:

Can't install RMagick 2.16.0. Can't find MagickWand.h.
And if it can not be installed, the whole application can not be started. I tried all the answers from here, and none of them works on MacOS :-( I reinstalled imagemagick and pkg-config with homebrew, and tried various version of RMagick without success. 2.16.0 is the latest version of RMagick currently.
MagicWand seems to be used in ImageMagick version > 6.9, and it can be found on the machine:
find /usr/local -name MagickWand.h
=> /usr/local/Cellar/imagemagick/6.9.5-9_1/include/ImageMagick-6/wand/MagickWand.h
find /usr/local -name MagickWand.pc
=> /usr/local/Cellar/imagemagick/6.9.5-9_1/lib/pkgconfig/MagickCore.pc
It does not work even if I specifiy the these paths during the gem install (same error as above) :-(
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.9.5-9_1/include/ImageMagick-6 PKG_CONFIG_PATH=/usr/local/lib/pkgconfig gem install rmagick
UPDATE:
The error only occurs for Ruby 1.8.7, it is possible to install RMagick for Ruby 2.0 and Ruby 2.3. Ruby 1.8.7 and ImageMagick 6.9.5 do not seem to be compatible.
Ruby 1.8.7 x
Ruby 2.0.0 ✓
Ruby 2.3.1 ✓
To solve the issue in Mac OSX Sierra, High Sierra, El Capitan, Mojave, Catalina, Big Sur, and Monterey (M1 chip), you can do the following:
brew unlink imagemagick
brew install imagemagick#6 && brew link imagemagick#6 --force
imagemagick#6 is keg-only, so you'll need to force linking.
I had this same issue with ImageMagick 7.0.4-4. The proper fix is to install imagemagick#6. I found https://github.com/Homebrew/homebrew-core/pull/8756 useful if you accidentally deleted your imagemagick#6 or never had it installed in the first place.
macOs Sierra:
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
First of all
unlink your installed imagemagick which was not properly installed in latest mac high sierra by using.
brew unlink imagemagick
then install latest imagemagic6 using below command
brew install imagemagick#6 && brew link imagemagick#6 --force
Then install gem rmagick using below command
gem install rmagick
It will work perfectly fine.
yah this one solves my issue:
MacOS X Sierra:
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
Many things have changed in ImageMagick 7 like this path: include/.../wand , and wand/MagickWand.h is hardwired in the rmagic gem at the moment. In my case it was not possible to update the gem since the project is rather old. So I ended up installing an older version of ImageMagic.
You can install the latest version from 6.x.x:
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/6f014f2b7f1f9e618fd5c0ae9c93befea671f8be/Formula/imagemagick.rb
You can also pin it for later usege:
brew pin imagemagick
Something changed with ImageMagick 7.0.4-4 for me. wand/MagickWand.h couldn't be found any more:
% brew unlink imagemagick && brew link imagemagick
Unlinking /usr/local/Cellar/imagemagick/7.0.4-4... 71 symlinks removed

RMagick depends on an outdated version of imagemagick, version 6.(see below) Homebrew offers this as a keg-only package, which you can install with:
brew install imagemagick#6
The build output will include a Caveats section (also available from brew info imagemagick#6 if you cleared the output):
==> Caveats
imagemagick#6 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have imagemagick#6 first in your PATH run:
echo 'export PATH="/usr/local/opt/imagemagick#6/bin:$PATH"' >> ~/.zshrc
For compilers to find imagemagick#6 you may need to set:
export LDFLAGS="-L/usr/local/opt/imagemagick#6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick#6/include"
For pkg-config to find imagemagick#6 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig"
Rather than force-linking, which has the potential to cause problems with other software that does support newer versions of imagemagick, you can use the suggested exports to make the RMagick gem pick up the old version while it builds:
export LDFLAGS="-L/usr/local/opt/imagemagick#6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick#6/include"
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig"
gem install rmagick
Go help contribute to the upgrade effort if you know Ruby and C!
Install imagemagick version 6 because version 7 is not compatible:
$ brew install imagemagick#6
Should not link --force the older version because this will change the binaries in your path and the good brew doctor will complain.
Reference the headers and libraries from version 6 that was installed when building the native extension of the gem:
$ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick#6/6.9.10-14/lib/pkgconfig/ gem install rmagick -v '2.16.0'
Note: Worked for me without indicating the lib and include folder because the pkgconfig is responsible for this.
Note: 6.9.10-14 is the latest version of imagemagick#6, but feel free to change it if you need to use a different version
$ brew remove imagemagick && brew install imagemagick
$ brew uninstall pkg-config && brew install pkg-config
$ brew unlink pkg-config && brew link pkg-config
$ gem install rmagick
I don't have the reputation yet to leave this as a comment improving another answer, but #Evgeniy28's answer worked for me on Sierra only after also installing pkg-config, which doesn't come installed by default on a fresh Sierra machine.
So:
brew install pkg-config
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
Success:
$ gem install rmagick

Here is how I solved (after lots of tries and fail) on macOS High Sierra 10.13.3 with Homebrew:
it seems that RMagick 2.16.0 is not compatible with the newest version of ImageMagick (Version 7): http://wordsandmagic.com/2017/09/01/RMagick-2-16-0-Error-MagickWand
I uninstalled imagemagick: brew uninstall imagemagick
Then I installed Imagemagick with this formula: https://gist.github.com/JagdeepSingh/4b03cbeab16cc0bc729bbc6d275402d3
gem install rmagick
If you have already installed an old version Imagemagick, this should work: https://stackoverflow.com/a/41674363
There's no need to link or unlink anything, following the instructions from the brew install script helps:
brew install imagemagick#6
LDFLAGS="-L/usr/local/opt/imagemagick#6/lib" CPPFLAGS="-I/usr/local/opt/imagemagick#6/include" PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig" gem install rmagick

Voila, I'm now able to run this application locally.
Got same error for alpine 3.9 image build. It comes with ImageMagick 7.0.8.38-r0
To fix that you either use alpine 3.5 with ImageMagick 6.9.6.8-r1:
FROM alpine:3.5
Or install ImageMagick 6.9.6.8-r1 with package repository for 3.5:
RUN apk add imagemagick-dev=6.9.6.8-r1 --repository http://dl-3.alpinelinux.org/alpine/v3.5/main/
There is an open issue in rmagick repo regarding failed builds for ImageMagick 7.0.x. so hopefully it will be fixed soon.
Something was severely wrong on my system, so badly that it was completely f*d up, but I was finally to able to install RMagick for Ruby 1.8.7 again after I installed
an older version of ImageMagick with Homebrew
a new Ruby version of 1.8.7
a new version of GCC
The installation of a new Ruby version with RVM rvm install 1.8.7 also installed a new GCC compiler: it removed an older GCC version 4.6 and installed GCC version 4.9. Apparently GCC was not able to find the right headers despite pkg-config.
First, you don't need to uninstall imagemagick if it has a 6.x installed, like shown below. You can see the current "main" is 7.0.7-8 but 6.9.1-10 is still there.
$ brew info imagemagick
imagemagick: stable 7.0.7-8 (bottled), HEAD
Tools and libraries to manipulate images in many formats
https://www.imagemagick.org/

Poured from bottle on 2017-08-21 at 14:44:16
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula
If you don't have an old 6.x version, then install imagemagick#6.
Second, do not force link imagemagick, especially not 6. EDIT: See ¹
You need to set PKG_CONFIG_PATH in addition to the --with-opt-* flags.
This works for me on High Sierra with aforementioned brew setup on Ruby 1.9.3-p551:
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.1-10/lib/pkgconfig \
gem install rmagick -v '2.16.0' -- \
--with-opt-lib=/usr/local/Cellar/imagemagick/6.9.1-10/lib/ \
--with-opt-include=/usr/local/Cellar/imagemagick/6.9.1-10/include/ImageMagick-6/
Building ri docs fails, but those are inconsequential.
¹: Building works, the dylib path RMagick is searching is wrong though. Raised Issue #278 to clarify if this can be fixed. Otherwise manual symlinking of libMagickWand etc is necessary. Might still be safer to manually link the specific libraries than a brew link --force though.
I fully explain the installation process in ImageMagick install in centos .
anyway ...
after install Install Imagick & ImageMagick-devel & ImageMagick PHP library like below:
# yum install ImageMagick
# yum install ImageMagick-devel
# pecl install Imagick
go to /usr/include
cd /usr/include
Important: copy ImageMagick folder from "/usr/include" to "/usr/local/include" for ImageMagick find "MagickWand.h"
I tested this change on imagick-3.4.3(ImageMagick-7) and centos 6.5 and php56 and works perfectly ...
If you have already installed "ImageMagick" several times, first remove all of them and find "ImageMagick" & "imagick" folders and clean all of them and continue the installation process with this change.
Use the following command to find a file or folder:
find / -name 'ImageMagick*'
find / -name 'imagick*'
and continue your installation
before below lines don't forget:
go to "php.ini" find "disable_functions" and clean "proc_open,popen,proc_close" becuase make imagick needs these functions,
after complete installation you can add this functions to your "disable_functions" on "php.ini" file.
# phpize
# ./configure --with-php-config=/usr/local/php56/bin/php-config
...
Good luck...
For Ubuntu version > 12 and not using homebrew,
wget http://www.imagemagick.org/download/<required_imagemagick_version>
tar -xvf <path_to_your_downloaded_file>.tar.gz
If you are getting '7z' files instead of 'tar.gz' files in the wget link, then
7z x <path_to_your_downloaded_file>.7z
cd <path_to_your_downloaded_file>/
make
./configure
sudo make install
sudo ldconfig /usr/local/lib
Then you can resume your bundler for RMagick.

I install all the packages needed (imagemagick libmagickwand-dev, etc, I have tried all the packages described in other questions)
Does someone had the same problem? Any clue?
Everything was working fine before updating to 15.04
EDIT
I managed to make it work purging imagemagick and installing from source http://www.imagemagick.org/script/install-source.php?ImageMagick=9s6tlikqbn5eb0u0spg5o38sa4#unix
Now gives me this error: This installation of RMagick was configured with ImageMagick 6.9.1 but ImageMagick 6.8.9-9 is in use.
I had the same problem and I fixed it up updating rmagick. What I did was:
sudo apt-get install libmagickwand-dev imagemagick
bundle update rmagick
And now bundle works correctly.
I am on ubuntu 15.04 and was able to get it by specifying version of rmagick
gem 'rmagick', '2.15.0'
I ran into same problem on clean Ubuntu 15.4 installation. Upgrade rmagick from 2.13.2 to 2.15.0 helped.
Things I tried, that did not help:
manually symlink in /usr/include/wand MagickWand.h ⇒ magick_wand.h;
rolling back to libmagickcore-dev.
Hope it helps.
If you are on Debian/Ubuntu I was able to fix it by doing the following:
sudo apt-get install libmagickwand-dev
sudo apt-get install graphicsmagick-imagemagick-compat
PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH" gem install rmagick -v '2.13.2'
your lib versions may be different so check the version in /usr/lib/x86...

libiconv is missing.
However, looking at nokogiri's mkmf.log, the following errors are shown:
ld: warning: ignoring file /usr/local/Cellar/libxslt/1.1.28/lib/libxslt.dylib, **file was built for x86_64 which is not the architecture being linked (i386)**: /usr/local/Cellar/libxslt/1.1.28/lib/libxslt.dylib
ld: warning: ignoring file /usr/local/Cellar/libxml2/2.9.1/lib/libxml2.dylib, **file was built for x86_64 which is not the architecture being linked (i386)**: /usr/local/Cellar/libxml2/2.9.1/lib/libxml2.dylib

I have xcode and it's command tools installed.
My ~/.bash_profile has 64bit compiling forced by: export ARCHFLAGS="-arch x86_64"
I have libxml2, libxslt, and libiconv installed via Homebrew, and each is linked.
I've tried installing all of these without the ARCHFLAG in .bash_profile.
I've also brew install apple-gcc42 and linked, as per how tos I've found.
I've tried installing nokogiri by passing paths to libxml2, libxslt, and libiconv in /usr/local/Cellar/, but the install still fails, with same errors as above.
I've wasted at least a day on this - just trying to get one Ruby gem installed. I'd really like to get back to actually developing.
Can anyone please help?
Setting NOKOGIRI_USE_SYSTEM_LIBRARIES=1 before actually installing the gem did the trick for me.
Summarising:
If previously installed, uninstall the gem:
$ gem uninstall nokogiri
Use Homebrew to install libxml2, libxslt and libiconv if needed:
$ brew install libxml2 libxslt libiconv
Install the gem specifying the paths to the libraries to be linked against:
$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"
Check if HomeBrew is installed correctly with the appropriate XCode command line tools.
brew doctor
You can also check via XCode > Preferences
With valid command line tools installed, I was able to resolve the nokogiri error encountered after the OSX Maverick upgrade.
Also found that some of the 'brew' packages were outdated after the OS X Mountain Lion to Maverick upgrade. (e.g. qt, postgresql)
Here's what worked for me:
If you haven't already done so, install the XCode developer tools: $ xcode-select --install
Use homebrew to install (or reinstall) libxml2, libxslt and libiconv: $ brew install libxml2 libxslt libiconv
Install nokogiri: gem install nokogiri -- --with-iconv-dir=/usr/local/opt/libiconv
I found the solution I needed in an unmerged pull request to update the Nokogiri tutorials. I recommend that if someone else encounters this issue and has exhausted the solutions here, check that pull request list to see if someone has submitted an update to the instructions on the Nokogiri tutorials page.
From github page
First, you should:
xcode-select --install
and then re-install nokogiri.
That worked for me while another suggestion didn't. Hope this helps someone else.
