First of all see the excellent installation manual by Martyn Plummer and Bill Northcott (JAGS Version 3.4.0 installation manual) at section 2 “Mac OS X”.

For the rest of us (me included) thinking  ./configure without any options will do the job are getting the following error:

configure: error: "You need to install the LAPACK library"

(It will not work even with the  –with-lapack=’-framework vecLib’ option.)

Do not follow this instruction! You do not have to install the LAPACK library because on OS X 10.9 the optimized (accelerated by Apple engineers) version of LAPACK is allready installed, see the LAPACK(7) Mac OS X Manual Page.

From now on just type the slightly modified commands in your bash-shell (terminal):

export CC=/usr/bin/clang

export CXX=/usr/bin/clang++

export CFLAGS="-g -Os -mmacosx-version-min=10.6 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -arch i386 -arch x86_64"

export CXXFLAGS="-g -Os -mmacosx-version-min=10.6 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -arch i386 -arch x86_64"

export FFLAGS="-g -Os -mmacosx-version-min=10.6 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -arch i386 -arch x86_64"

export LDFLAGS="-mmacosx-version-min=10.6 -arch i386 -arch x86_64"

./configure --disable-dependency-tracking --with-included-ltdl

make -j 8

sudo make install

Of course, make sure you have installed all the required tools before executing the commands.

Happy ./configuring!
