Hi, I'm trying to compile some code(with pthread.h included) where I test a trylock return against the variable EBUSY. Although, when compiling with -c -g -ansi -Wall -pedantic I get the following error, error: ‘EBUSY’ undeclared (first use in this function) (gcc -dumpversion = 4.3.3 @ ubuntu jaunty - 2.6.28-11-generic) -- View this message in context: http://www.nabble.com/Problem-with-pthread---EBUSY-tp22871393p22871393.html Sent from the gcc - Help mailing list archive at Nabble.com.
