no pthread_yield() on netbsd

[jym]

pthread_yield() function doesn't exist on netbsd. Use sched_yield() instead.

 With this modification, compilation is OK on Netbsd. MacosX seems to have the same problem (but I did not try to compile pbxt on it).

Hi JYM,

Thanks for the bug report! Please check if the following code solves the problem:

xtPublic void xt_yield(void)
{
#ifdef XT_WIN
 Sleep(0);
#elif defined(XT_MAC)
 usleep(0);
#else
#if defined(__NetBSD__)
 sched_yield();
#else
 pthread_yield();
#endif
#endif
}

Hello,

Sorry for the late reply..

yes, that's ok for this file. But I now have another problem with
compilation. (I have a netbsd updated to current and mysql 5.1.28:
(gcc v4.1.3)

When linking mysqld (I'm compiling pbxt in mysql):
 undefined reference to `typeinfo for handler'

I will see that error as soon as possible. And try the latest mysql.
I will keep you updated.

Thank you, and Greetings from Paris.

Hi JYM,

the problem with missing reference is on MySQL side. To make things work you will need to conifugre MySQL with the following option: --with-mysqld-ldflags=-export-dynamic

e.g.:

./configure --with-extra-charsets=complex --with-mysqld-ldflags=-export-dynamic
make
make install (as root)

This worked for me. However I had some problems using PBXT right after the INSTALL PLUGIN command. So I had to restart MySQL server and after that everything worked fine.

And we have pushed the xt_yield() bug fix to 1.0.07, so I am closing this bug.
