Build for macOS

We've been using gtk-osx to make the OS X binaries in the nip2 release area.

We have a OS X build system based on jhbuild that automates the whole process. Check the README.

Homebrew

VIPS is on homebrew. Install homebrew and type:

$ brew install vips

To verify your vips install, try:

$ vips --version
vips-8.6.3-Thu Mar  8 15:18:35 UTC 2018

This is a good way to get libvips on your system, not so great for nip2.

This will give you a vips with just the basic optional packages, missing things like imagemagick loading, openslide support, and so on. To get a list of all the optional dependencies, try:

$ brew info vips

For a full-fat version, try:

$ brew install vips --with-cfitsio --with-imagemagick --with-openexr --with-openslide --with-webp

vips will also work with graphicsmagick, which you may prefer. Swap --with-imagemagick for --with-graphicsmagick to use that library.

Python should just work, as long as you use the homebrew Python and not the Apple one. You should see:

$ which python
/usr/local/bin/python

Homebrew and Ruby

If you want to build things outside homebrew which depend on vips, such as ruby-vips, you will need to get your pkg-config working. You need to point pkg-config at the homebrew area, and, additionally, at various homebrew add-on areas.

In your .profile, add something like:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/local/opt/libxml2/lib/pkgconfig:/opt/X11/lib/pkgconfig:/usr/local/opt/libffi/lib/pkgconfig

To verify that pkg-config is working correctly with vips, try:

$ pkg-config vips --libs
-L/usr/local/Cellar/vips/7.32.1/lib ... a lot of stuff

From GIT on OS X

To build from source yourself on OS X, first install via homebrew to pull in the necessary packages, then uninstall, clone the git repository and build yourself.

Roughly:

brew install homebrew/science/vips --with-webp --with-graphicsmagick
brew uninstall vips
brew install openexr openslide homebrew/science/libmatio cfitsio libjpeg-turbo

Now set up your environment for building outside brew. You need to set PKG_CONFIG_PATH, I have something like this in my .profile:

function addpkg() {
  export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:$1/pkgconfig"
}

export PKG_CONFIG_PATH=
addpkg /usr/local/lib
addpkg /usr/local/opt/libxml2/lib
# we use xquartz: cairo needs those .pc as well
addpkg /opt/X11/lib
addpkg /usr/local/opt/libffi/lib

You need to set PATH to search /usr/local/. I usually build development versions of vips to a private area in my home, so I add that as well.

export VIPSHOME=$HOME/vips
export PATH=/usr/local/bin:$VIPSHOME/bin:$PATH
addpkg $VIPSHOME/lib

You have to tell Python and gobject-introspection about the private vips area:

export GI_TYPELIB_PATH=/usr/local/lib/girepository-1.0:$VIPSHOME/lib/girepository-1.0
export PYTHONPATH=$VIPSHOME/lib/python2.7/site-packages:$PYTHONPATH

You need some extra packages to build vips from GIT:

brew install autoconf automake gtk-doc swig

And now you can finally clone and build vips.

git clone git@github.com:jcupitt/libvips.git
cd libvips
CFLAGS="-g -Wall" CXXFLAGS="-g -Wall" ./autogen.sh --prefix=$HOME/vips --with-jpeg-includes=/usr/local/opt/jpeg-turbo/include --with-jpeg-libraries=/usr/local/opt/jpeg-turbo/lib 

The vips Python binding won't be able to install Vips.py for you, you need to do this by hand.

cd python
cp Vips.py /usr/local/lib/python2.7/site-packages/gi/overrides/

Fink

VIPS and nip2 are available via Fink. To install the nip2 end user program, type

fink install nip2

To use VIPS outside of Fink, you'll need the development package libvips31-dev (for VIPS version 7.34.2). The VIPS tools are in libvips-tools. To verify your vips install, try:

$ vips --version
vips-7.34.2-Tue Oct  1 19:42:09 EDT 2013

In order for your project to find the library, add /sw/lib/pkgconfig (replace "/sw" as appropriate for your Fink install root) to the environment variable PKG_CONFIG_PATH:

export PKG_CONFIG_PATH=/sw/lib/pkgconfig:$PKG_CONFIG_PATH

To verify that pkg-config is working correctly with vips, try:

$ pkg-config vips --libs
-L/sw/lib -lvips ... a lot of stuff

Macports

VIPS and nip2 are in Macports. Follow the install instructions, then:

$ sudo port install vips
$ sudo port install nip2

That will make a nip2 which uses X11 for display. You can make a nip2 that uses the native OS X backend like this:

$ sudo port install nip2 +no_x11 +quartz
