Subject Re: Re: how to build an mt version of shared lib for zookeeper under cygwin?
Date Thu, 08 Apr 2010 06:32:18 GMT
$ ls /usr/lib/*pth*
/usr/lib/libpthread.a

checking for pthread_mutex_lock in -lpthread... yes

Attach is the complete log for configure and make. Am i just getting bad luck :(

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* 
/usr/lib/libpthread.a* 

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.
