Description Alex Afanasyev 2011-09-28 14:37:45 UTC

On Ubuntu 11.04 librt requires libpthread.  As a result, when ./waf tries to check whether librt present, it fails with unresolved pthread symbols.  

The following solves the problem:

line 87 in src/core/wscript
- if not conf.check(lib='rt', uselib='RT', define_name='HAVE_RT'):
+ if not conf.check(lib='rt', uselib='RT, PTHREAD', define_name='HAVE_RT')
