Unable to start SOLR server (Ruby on Rails)

Question

I'm using sunspot_rails and sunspot gems in my Rails3 application and following the steps to installing sunspot on https://github.com/outoftime/sunspot , I cannot get my sunspot server to run.

When I enter my directory, run bundler and then run rake sunspot:solr:start I get the following error

Emil@Emil-PC /cygdrive/c/work/pilarhq
$ rake sunspot:solr:start

Answer 1

I have found http://www.garethhunt.com/2008/02/11/cygwin-died-waiting-for-dll-loading/ and had to do the following:

1. close all cygwin windows
2. call c:\\cygwin\\usr\\bin\\ash from Run (Win-R)
3. call rebaseall from therein

Answer 2

I ran into something similar (Windows 7 enterprise, using cygwin and rails) and found that the simple rebaseall approach was not working. In brief, the problem is that rebaseall doesn't necessarily know all the .dll's and .so's it has to fix. The solution is to compose your own list and run rebaseall against that list using the -T option. For me, the process that finally worked was:

1. in a cygwin shell: find /bin /lib /usr -iname '*.so' > /tmp/to_rebase.lst
2. in a cygwin shell: find /bin /lib /usr -iname '*.dll' >> /tmp/to_rebase.lst
3. quit all cygwin shells and stop all cygwin processes
4. run as Administrator C:\\cygwin\\bin\\ash.exe
5. /bin/rebaseall -T /tmp/to_rebase.lst
6. exit ash
7. restart machine
