I'm running on nitrous.io and trying to install the rgeo gem using ruby 2.0.0-p353.
I don't have sudo
access, so I tried to compile and install geos from source.
Once I downloaded and untarred the source files, I cd
into the source folder and run
mkdir /home/action/local && ./configure --prefix=/home/action/local
make && make install
This runs for a bit. I then run
gem install rgeo -- --with-geos-dir=/home/action/local
Things look alright, but if I hop into a terminal I get
RGeo::Geos.supported?
> false
Looking back over the mkmf.log
file, I see these lines:
/usr/bin/ld: cannot find -lgeos
/usr/bin/ld: cannot find -lgeos_c
/usr/bin/ld: cannot find -lgeos
/usr/bin/ld: cannot find -lgeos_c
This blog post: http://blog.thefrontiergroup.com.au/page/2/ mentions creating symbolic links to fix this issue:
cd /usr/lib
sudo ln -s libgeos-3.3.3.so libgeos.so
sudo ln -s libgeos-3.3.3.so libgeos.so.1
libgeos
isn't installed to usr/lib for me, it's in /home/action/local/lib
and when I check that directory I see libgeos.so
is already symlinked to libgeos-x.x.x.so
.
If I switch ruby versions to 1.9.3-p392 and run the gem installation line, everything works as planned.
On my MacBook Pro I can successfully use rgeo
with ruby 2.0.0-p395
, but the geos library is installed by homebrew and therefore in a path rgeo
is expecting.
Was there a change with ruby 2.0 that affects compiling gems?
