Subject Re: how to build an mt version of shared lib for zookeeper under cygwin?
Date Thu, 08 Apr 2010 05:24:37 GMT
when you run configure what does it say for pthreads?

My cygwin says this:

checking for pthread_mutex_lock in -lpthread... yes

Do you have pthreads libs in /usr/lib?

I see:

$ ls /usr/lib/*pth*

You could also try running configure and the build, capture all the 
output and attach as a gzip'd file (or create a jira and attach there if 
you like). Should help to get to the bottom of the issue.
