Subject RE: Threads in a module
Date Sat, 22 Nov 2003 01:05:14 GMT
Sonry, i don't write in english very well, when you do a programm which
uses threads you must compile with: 
		gcc example1.c -o example.out -lpthread

My question is when i compile the apache sources, with make, make all
and make install, where i must indicate the option -lpthread.
In the module i include <pthread.h>

Hey David,

A question like yours is probably better asked on the apache-modules
list. You can get on that by sending an empty mail to

If lpthread wasn't part of your link phase, you'd get issues with
unresolved symbols either at link time or at run time. You may want to
check if the code that creates the thread actually gets executed, or
doesn't get executed more than once.
