Geoip_city on Mac OS

July 11th 2010

Today, I spent a time to install gem geoip_city. So what did I do:

Get latest version of GeoIP C Api from http://geolite.maxmind.com/download/geoip/api/c/

    wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP-1.4.6.tar.gz
    tar zxf GeoIP-1.4.6.tar.gz
    cd GeoIP-1.4.6

Read file README.OSX. Found simple instructions to compile this lib.

    export GEOIP_ARCH='-arch i386 -arch x86_64 -arch ppc -arch ppc64'
    export MACOSX_DEPLOYMENT_TARGET=10.4
    export LDFLAGS=$GEOIP_ARCH
    export CFLAGS="-mmacosx-version-min=10.4 -isysroot /Developer/SDKs/MacOSX10.4u.sdk $GEOIP_ARCH"
    ./configure --disable-dependency-tracking
    perl -i.bak -pe'/^archive_cmds=/ and !/\bGEOIP_ARCH\b/ and s/-dynamiclib\b/-dynamiclib \\\$(GEOIP_ARCH)/' ./libtool
    make

When run all this stuff, I did not get a success result, I still have a error when install gem.
show available SDKs in you host
```
ls /Developer/SDKs 
```
I got two: MacOSX10.5.sdk MacOSX10.6.sdk
So change line in readme file before

export CFLAGS="-mmacosx-version-min=10.4 -isysroot /Developer/SDKs/MacOSX10.4u.sdk $GEOIP_ARCH"

export CFLAGS="-mmacosx-version-min=10.4 -isysroot /Developer/SDKs/MacOSX10.6.sdk $GEOIP_ARCH"

and execute all steps from README file.
but found a problem in step configure:

% ./configure --disable-dependency-tracking
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

I choose another SDK and set to “MacOSX10.5.sdk”
run again all steps
then install gem and all works fine

if you have troubles to install gem and still see next message:

checking for GeoIP_record_by_ipnum() in -lGeoIP... no
you must have geoip c library installed!
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
     --with-opt-dir
     --without-opt-dir
     --with-opt-include
     --without-opt-include=${opt-dir}/include
     --with-opt-lib
     --without-opt-lib=${opt-dir}/lib
     --with-make-prog
     --without-make-prog
     --srcdir=.
     --curdir
     --ruby=/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
     --with-geoip-dir
     --without-geoip-dir
     --with-geoip-include
     --without-geoip-include=${geoip-dir}/include
     --with-geoip-lib
     --without-geoip-lib=${geoip-dir}/lib
     --with-GeoIPlib
     --without-GeoIPlib

So you should add include /usr/local/lib to DYNLD_LIBRARY_PATH. Or do next: in step of configuration do ./configure —disable-dependency-tracking —prefix=/opt/GeoIP and then next steps from README. I suggest do make clean before each compiles. And then sudo gem install geoip_city — —with-geoip-dir=/opt/GeoIP to install gem.
