MySQL Client / pthread Problem
Nick Vargish
Greetings,
Sorry if this is the wrong list, or if the answer is available in some
other (less intrusive) forum[1].
I am trying to use MySQL and a couple of tools on my OpenBSD 2.6 system. I
successfully built and installed MySQL using the ports facility. It runs
fine, and I can create databases and tables, run SELECTs and so on.
The problem crops up when I try to build tools that use the libmysqlclient
shared library. I get this error with php (by looking in the logs) and
with xmysql (built from within ports facility, by the way):
imrryr$ xmysql
/usr/libexec/ld.so: Undefined symbol "_pthread_key_create" called from
xmysql:/usr/local/lib/libmysqlclient.so.6.0 at 0x40039538
According to the system man pages, pthread_key_create does indeed exsit.
It doesn't seem to matter what I set my LD_LIBRARY_PATH to, but I'm open
to any suggestions.
Thanks for any advice or help you can pass my way,
Nick

Not 100% sure: but one must compile and link all threaded
programs with flag -pthread also if they itself are not
using threads (see 'man pthreads') ... hope this helps ...

to be linked to -lc_r also
This may be a bug in the current linker, not giving you an error when you
don't do this. Libmysqlclient calls some stuff in the libc_r
