- Subject: problems with pthread library
Hello group:
I'm begining to migrate a 10k lines of code project to use the GNU tools.
I'm using eclipse 3.1 & CDT + latest Cygwin.
I have rewrite the OS Layer to begin use pthread library for
multi-threading capabilites.
When i try to debug my program i note the CPU going almost 100% with my
program & gdb.exe taking most of it. The program never goes further.
If i run the program without the debugger everything goes well.
So i decided to investigate more and found where the program hangs.
I found that when creating mutexes the debugger get lost. Not after the
first call but after a couple of invocation of 'pthread_mutex_init' &
'pthread_cond_init'.
I can repro the similar problem without using eclipse but directly using
cygwin and gdb.
Any hints on what is going on ?
Thanks,
Rodrigo.
